Dear Shareholder,
 
As communicated to you in a separate letter, Van Kampen American Capital is
consolidating all of the retail mutual funds that we distribute under the single
name of Van Kampen Funds. This move accompanies the change in our legal name to
Van Kampen Funds Inc.
 
You can be assured that the change in your fund's name will not affect its
management or daily operations. You will begin seeing the application of this
change with this report. In addition, as of August 31, your fund, with the
exception of the Government Obligations Money Market Fund and the Money Market
Fund, will be listed in the daily newspapers by share class under the heading
"Van Kampen Funds." For your convenience, we have enclosed a separate brochure
that covers additional details related to these changes.
 
ECONOMIC REVIEW
 
The economic crisis in Asia deepened late in the reporting period while growth
continued at a robust pace in the United States and Europe. After last fall's
currency crisis, signs of recovery began to appear in Asia early in 1998 as
equity markets rebounded and currency values stabilized. But a steep decline in
the Japanese yen beginning in February undermined investor confidence in the
region and ignited fears of yet another round of currency devaluations. At the
heart of the problem was a sudden worsening of economic conditions in Japan and
the perceived inability of Japanese leaders to rescue the country's ailing
banking system.
 
Despite the drag from Asia, the U.S. economy continued to expand at a healthy
rate. The nation's inflation-adjusted output of goods and services ran at 5.4
percent during the first quarter, an annualized rate considered by many
economists to be virtually unsustainable without leading to inflation. As the
reporting period ended, however, there were indications that the Asian financial
crisis was finally having a moderating impact on domestic economic growth. Also,
the Conference Board's index of leading indicators points toward a slowdown in
economic growth for later this year.
 
In Europe, economic growth accelerated as the region looked forward to monetary
union, set to begin in January 1999. At that time, a common currency (the euro)
will begin to replace the currencies of the 11 participant nations. The
elimination of foreign-exchange risk within these 11 countries and widespread
financial reforms has led to a wave of mergers and acquisitions across the
region.
 
MARKET REVIEW
 
The wide variation of returns from global financial markets during the reporting
period reflected the vastly different circumstances in the three major economic
blocks of the United States, Europe, and Asia. In Europe, where companies have
relatively little exposure to Asia, stocks posted impressive gains. During the
12 months ended in June, the Dow Jones Europe/ Africa Index climbed 30.39
percent in U.S. dollar terms. The rally was broad based, with markets in
Finland, France, Germany, Greece, Ireland, Italy, Portugal, and Spain each
climbing more than 30 percent. European bonds also benefited from stable
monetary policy and low inflation.
 
Stock prices in the United States continued to move higher during the period,
but the Asian financial crisis had an uneven impact on corporate profits. The
Wilshire 5000 Index, consisting of all publicly traded U.S. companies, gained
26.32 percent during the 12-month period. Companies with heavy exposure to
domestic consumers benefited from strength in the American economy, while
commodity-related issues lagged. U.S. bonds benefited from a global flight to
quality and from a growing perception that domestic economic growth was slowing.
The yield on the Treasury's 30-year benchmark bond declined from 5.92 percent on
December 31, 1997 to 5.62 percent by the end of the period.
 
In Asia, renewed currency concerns caused major declines in nearly all equity
markets. Despite a solid rally in January, the Dow Jones Asia/Pacific Index
(excluding Japan) fell 48.77 percent during the 12 months through June and by
18.69 percent during the first half of 1998. The worst-performing Asian market
was Indonesia, where the average stock lost nearly two-thirds of its value amid
a deepening recession, political turmoil, and social unrest. Also, for the 12
months through June, the Dow Jones Indonesia Index declined by 87.66 percent in
U.S. dollar terms.
 
OUTLOOK
 
We remain optimistic about the prospects for European equity markets, based on
the region's accelerating growth rate and the introduction of a common currency
next year. As interest rates decline, liquidity should increase as more European
investors leave the sanctuary of money-market funds in favor of equities.
 
Our outlook for Asia is guarded. As the reporting period ended, the Japanese
government announced a bank bailout package that ignited a rally in Asian
financial markets. While we view the latest reforms in a positive light, we are
concerned that investor reaction to the news may have been overly euphoric.
 
                                                              ------------------
                                                                    1

                             LETTER TO SHAREHOLDERS
 
- --------------------------------------------------------------------------------
 
In the United States, economic growth is likely to slow in coming months as the
impact of the Asian crisis becomes more evident. With equities already trading
at record-high valuations, we are cautious about the ability of U.S. stocks to
rally significantly from current levels. On a longer-term basis, however, we
believe the environment for domestic equities remain highly positive.
 
Several factors are helping to sustain a generally bullish environment for
global bonds. Extreme economic weakness in Asia is exerting downward pressure on
energy, commodity, and goods prices. Also, the strong dollar is containing U.S.
inflation despite a tight labor market and above-trend economic growth.

In accordance with SEC regulations, Fund performance since inception as shown at
left assumes that: the maximum sales charge was deducted from the initial
investment of $10,000 in Class A shares; all recurring fees (including
management fees) were deducted; and all dividends and distributions were
reinvested. The graph presents the performance of Class A and Class C shares
which have been in existence since the Fund's inception. The performance of
Class B shares will vary based upon the different inception date and the sales
charge and fees assessed to that Class.
PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE PERFORMANCE.
 
The Van Kampen Aggressive Equity Fund, formerly the Morgan Stanley Aggressive
Equity Fund, seeks long term capital appreciation by investing primarily in a
non-diversified portfolio of corporate equity and equity-linked securities of
predominately U.S. corporations. The portfolio tends to hold between 30 and 40
issues (we held 44 securities at June 30), and we can invest up to 25 percent in
a single security when our conviction is very strong. The Fund also has the
ability to sell securities short, although there were no short positions at the
end of the period.
 
For the year ended June 30, 1998, the Fund had a total return of 30.93 percent
for the Class A shares at net asset value, as compared to a total return of
24.90 percent for the Lipper Capital Appreciation Index and 30.17 percent for
the Standard & Poor's 500-Stock Index during the same period.
 
After strong, above-benchmark performance in the first three quarters of the
Fund's fiscal year, the portfolio had a disappointing final quarter, returning
- -4.23 percent versus 3.30 percent for the S&P 500 and 1.78 percent for the
Lipper Capital Appreciation Index. Among our best-performing issues in the final
quarter were Clear Channel Communications and Continental Airlines, whose stock
prices rose approximately 11.4 percent and 3.5 percent, respectively. However
these gains were not enough to offset the weakness we experienced when Cendant,
a top-ten holding, fell precipitously on its mid-April announcement of
"accounting irregularities."
 
The 62 percent weighting in our top ten positions is significantly more
concentrated than most U.S. equity portfolios, but is typical for this Fund.
Since inception in January 1996, the ten holdings have tended to account for
between half and three quarters of assets. Our belief is that heavy
 
THE PERFORMANCE RESULTS PROVIDED IN THIS OVERVIEW ARE FOR INFORMATIONAL PURPOSES
ONLY AND SHOULD NOT BE CONSTRUED AS A GUARANTEE OF THE FUND'S FUTURE
PERFORMANCE. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE SO THAT AN
INVESTOR'S SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL
COST.

                              INVESTMENT OVERVIEW
(CONT.)
 
CONCENTRATION MAY LEAD TO GREATER-THAN-AVERAGE VOLATILITY, BUT NOT NECESSARILY
GREATER-THAN-AVERAGE RISK. TO US, RISK IS SYNONYMOUS WITH LACK OF KNOWLEDGE,
WHICH OUR STRATEGY OF "SEEKING THE INFORMATION EDGE" ATTEMPTS TO AVOID. WE MAY
BE WRONG--AS WE WERE WITH CENDANT RECENTLY--BUT WE BELIEVE WE CANNOT BE FAULTED
FOR A LACK OF KNOWLEDGE REGARDING OUR COMPANIES. OVER THE LONG TERM, WE BELIEVE
THE ABILITY TO CONCENTRATE IN ISSUES WHERE WE HAVE EXTREMELY STRONG CONVICTION
SHOULD LEAD TO STRONG PERFORMANCE. THIS HAS BEEN THE CASE SINCE THE INCEPTION OF
THE FUND, WHICH HAS OUTPERFORMED THE S&P 500 INDEX AT A TIME WHEN THE MAJORITY
OF U.S. EQUITY FUNDS HAVE UNDERPERFORMED. LOOKING FORWARD, WE SEE AMPLE
OPPORTUNITIES FOR CAPITAL APPRECIATION IN INDIVIDUAL STOCKS, AND WE HIGHLIGHT A
FEW OF OUR LARGEST HOLDINGS BELOW.
 
Our biggest position, Continental Airlines, seems exciting for several reasons.
At $60 per share as of June 30, the stock trades at only ten times consensus
earnings expectations for 1998. Such a low valuation in today's market implies
that investors are wary about the company's ability to grow off the 1998 base.
Our research indicates that growth should be strong. We believe that consensus
earnings per share (EPS) expectations of $5.75 for 1998 and $5.95 for 1999 are
too conservative. Like other airlines, Continental has recently begun to deploy
free cash flow into share repurchases. This is very accretive to EPS and should
enhance value over time. In addition to using strong cash flow from operations,
we anticipate that the company will monetize its stake in Amadeus, an
international reservation system, over the next 6 to 12 months. This should
create cash proceeds of $300 million or more, in exchange for an asset with no
earnings. Management has publicly committed to using all of those proceeds for
share repurchase. At or near current prices, this would eliminate 6 percent of
total shares outstanding.
 
Clear Channel Communications has been a strong performer year-to-date and in
1997, and we continue to be excited about its prospects. Following the company's
recent acquisition of More Group of the United Kingdom, Clear Channel has become
the largest "out of home" advertising media company in the world. The company is
extremely well managed and has been a leader in consolidating the radio and TV
station business in the United States, and more recently the billboard industry.
Radio and billboard share some very positive characteristics: extremely low
capital reinvestment, high profit margins, and the probability of secular growth
through market share gains against traditional television advertising.
 
We bought Loews aggressively when the stock was quite weak in May and June.
However, we believe business fundamentals are intact. Loews, the Tisch family
holding company, is a very unusual stock. It is a holding company with a strong
track record of investments by management, but investors are placing an
incredibly low valuation on the stock: less than nine times projected 1998
operating profits and less than one times projected year-end book value. Why
such a low valuation? We think there are three primary reasons. First, Loews
owns Lorillard, the cigarette manufacturer. Second, the company holds a large
and widely publicized S&P 500 put position, which may exceed $1 billion. Third,
the company is, from time to time, an aggressive buyer of its shares but it has
not repurchased any stock in more than a year.
 
At this point, however, we see many reasons to be enthusiastic about Loews.
Managed by the Tisch family, Loews is committed to maximizing shareholder value
over time. For an investment holding company, this will equate to maximizing
book value over the long term. Over the past 12 years, Loews per share book
value has compounded at a 15 percent annual rate. Its stock price, however, has
grown at less than half that rate. Even assuming a slowdown to 10 percent annual
growth, we believe the book value should exceed $100 by the end of next year. In
addition, we believe Loews stock should act as a hedge if the U.S. market
finally cracks. Although we do not have a view that the market is going down, we
would note that the Tischs have been very right before, and sometimes early. For
example, in the early 1990s, Loews put together the largest offshore drilling
company in the world by buying rigs at below scrap value. Today, Loews owns 70
million shares of Diamond Offshore, valued at about $40 per share, with a cost
to Loews of under $1 per share. We are bullish on Loews stock with or without a
market decline. But in the case of a significant market retrenchment, Loews
would, in our view, be one of the best stocks on a relative basis.
 
For the first time in years, a technology stock--Microsoft--has made it into our
top ten. Typically, we shy away from large investments in technology because it
is difficult to stay ahead of the information curve. Although we have held
Microsoft for some time, we added to our position in April and May amid the
sell-off related to the Department of Justice lawsuit. Our view was that
investors were exaggerating the threat of government action. While the stock has
surged to new highs recently and it is not cheap statistically, Microsoft offers
a powerful combination of growth, extremely high margins, and low risk of
competitive threats. Keep in mind that not all stocks in the portfolio performed
as favorably, and there is no guarantee that any of these stocks will perform as
well in the future.

                              INVESTMENT OVERVIEW
(CONT.)
 
Our eleventh-largest holding as of June 30 was Cendant, a stock that has been in
the news since the company's announcement in mid-April of "accounting
irregularities" in its CUC division. (Cendant was created from the merger of CUC
and HFS last December.) The stock dropped about 46 percent, falling as low as
$17 per share. Although the final audit report is not yet available, our initial
assessment was that the market overreacted by taking the stock down so far, so
fast. (At prices in the teens, the market had effectively wiped out most of the
value of the CUC business.) We believe the core franchise and membership
business models of the company remain intact but feel there is more uncertainty
now. We await the final audit report with about a 2 percent position in the
stock, having reduced our exposure substantially.
 
As we begin the new fiscal year, the Fund is very much a combination of classic
or familiar growth names such as Microsoft, less familiar or traditional growth
opportunities such as Continental Airlines and Loews, and stocks that fall
somewhere in between.

In accordance with SEC regulations, Fund performance since inception as shown at
left assumes that: the maximum sales charge was deducted from the initial
investment of $10,000 in Class A shares; all recurring fees (including
management fees) were deducted; and all dividends and distributions were
reinvested. The graph presents the performance of Class A and Class C shares
which have been in existence since the Fund's inception. The performance of
Class B shares will vary based upon the different inception date and the sales
charge and fees assessed to that Class.
PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE PERFORMANCE.
 
The Van Kampen American Value Fund, formerly the Morgan Stanley American Value
Fund, seeks to invest in small- to medium-sized companies that our research
indicates are undervalued with improving business prospects. The Fund's approach
to value investing seeks to outperform the Russell 2500 Small Company Index over
the long term.
 
Our stock selection process favors companies that offer the greatest value in
terms of price/earnings ratio and earnings growth rate. Among the companies
offering attractive value, we generally favor those with improving near-term
business prospects relative to investor expectations. To help control risk, the
Fund is diversified across the major economic sectors.
 
For the 12 months ended June 30, 1998, the Fund generated a total return of
28.26 percent for the Class A shares at net asset value, compared to a total
return of 18.10 percent for the Russell 2500 Small Company Index.
 
Stock selection in the finance, technology, and consumer durable sectors was the
main positive contributor to the Fund's relative performance during the
reporting period. In the finance sector, Providian, Capital One, and Nationwide
Financial Services posted solid returns, as these companies' earnings grew
faster than expected. The returns in the technology sector benefited from stocks
such as Electronic Arts, a video game company, and Novell, a networking software
company. Building and housing stocks, such as Furniture Brands and Lone Star
Industries, posted solid returns in the consumer durable sector. Stock selection
in the consumer service and health care sectors had a negative effect on overall
performance.
 
THE PERFORMANCE RESULTS PROVIDED IN THIS OVERVIEW ARE FOR INFORMATIONAL PURPOSES
ONLY AND SHOULD NOT BE CONSTRUED AS A GUARANTEE OF THE FUND'S FUTURE
PERFORMANCE. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE SO THAT AN
INVESTOR'S SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL
COST.

                              INVESTMENT OVERVIEW   (CONT.)
 
After increasing the Fund's presence in building and housing stocks during the
first part of the fiscal year, we have recently taken profits in many of these
holdings given that valuations have become extended and revenue growth has
started to slow. We also reduced our weight in the energy service sector due to
deteriorating fundamentals. Within the technology sector, we generally reduced
the Fund's presence in cyclical technology stocks (such as semiconductors) and
reinvested the proceeds into software stocks (such as Novell and Electronic
Arts) and cable equipment stocks (such as General Instrument and Antec). In
addition, we increased the Fund's exposure to the consumer non-durable sector,
as we found reasonably priced stocks with stable or improving business
prospects.
 
While overall corporate profit growth may continue to slow, our dual emphasis on
earnings revisions and valuation should enable the Fund to perform relatively
well over the long term. In addition, small- and mid-cap stocks currently offer
compelling value relative to large-cap stocks. We expect this valuation gap to
eventually narrow, providing an attractive opportunity for long-term investors.

In accordance with SEC regulations, Fund performance since inception as shown at
left assumes that: the maximum sales charge was deducted from the initial
investment of $10,000 in Class A shares; all recurring fees (including
management fees) were deducted; and all dividends and distributions were
reinvested. The graph presents the performance of Class A and Class C shares
which have been in existence since the Fund's inception. The performance of
Class B shares will vary based upon the different inception date and the sales
charge and fees assessed to that Class.
PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE PERFORMANCE.

value, as compared to a total return of -60.20 percent for the Morgan Stanley
Capital International (MSCI) Combined Far East Free ex-Japan Index.
 
The period was marked by the Asian economic crisis, which had been triggered by
the collapse of the currency peg in Thailand on July 2, 1997. Excessive
borrowing by Thai companies had led to the baht's collapse; other regional
currencies began to succumb in turn. These regional currency woes soon spread to
the equity markets as concerns about the overleveraged economies, typified by
excessive bank lending and an overinvestment in property and infrastructure,
took their toll. In the past, Asia's fortunes flourished because it was an
inexpensive low-end manufacturing base with a cheap labor force, favorable tax
rates, and a fixed exchange rate pegged to the U.S. dollar. Through the years,
however, the massive inflow of foreign investment and loans inevitably led to
overcapacity and rampant overinvestment by local corporates. These concerns
precipitated the sell-down of the equity markets as international investors took
flight in expectation of major fallout.

                              INVESTMENT OVERVIEW
(CONT.)
 
As the markets collapsed during this period, our strategy was to identify
economies and companies that could best compete on a value-added basis in a
technological world, rather than on export ability alone. Economies like Hong
Kong, Singapore, and Taiwan were thought to be able to better withstand the
effects of the "Asian contagion." Nonetheless, the crisis spread unabated and
took its initial victims in Southeast Asia down 70 percent from earlier peaks.
Northeast Asia was not spared; the destruction of the Korean economy jolted
international markets with the sudden realization that the contagion could have
a far-reaching global impact.
 
As the currencies and equity markets took their blows, the remaining economies,
including Hong Kong, Singapore, and Taiwan looked more expensive and vulnerable.
Hong Kong faced the risk that China's economy was rapidly slowing, and that the
currency peg to the U.S. dollar was exacting a heavy toll on its economy.
Seemingly, China's problems would have a serious effect on Taiwan, which faced
its own difficulties in the electronics sector. A fallout in this area would
have also been hazardous for Singapore, which was already faced with the
disintegration of its neighbors.
 
Consequently, the Hong Kong and China exposure was reduced, and a hedge was
entered into to minimize currency exposure to the Hong Kong dollar, New Taiwan
dollar, and Singapore dollar. Concurrently, money was put to work in selected
stocks in the more devastated markets that we believe offered compelling values
for the patient investor. Our view was that investors with the luxury of a
longer-term horizon stood to reap long-term gains by capitalizing on this
monumental meltdown in the Asian markets. The strategy was to concentrate on
identifying for acquisition, companies and stocks that represented irreplaceable
franchises available at bargain basement levels.
 
The devastation of the Asian markets in the second half of 1997 was momentarily
reversed in the first quarter of 1998, with the regional MSCI Combined Far East
Free ex-Japan Index returning 9.8 percent. The Fund underperformed the Index,
returning 1.5 percent. Following the abolition of the two-tier exchange rate in
Thailand and the reform of labor laws in Korea, the Asian markets finally began
to stabilize in January.
 
International investors flooded into Malaysia in February as the market turned
upwards. We remained cautious, however, because of serious concerns about the
large corporate and personal debt that hung over the economy. As such, the focus
of the Fund's investments was on stocks with strong cash flows and low debt
levels, which could outperform as the debt situation climaxed. The respite from
the regional financial turmoil allowed heavily indebted stocks to surge on
weakening interest rates and a strengthening ringgit.
 
Our focus on a few key names in Korea, such as Samsung Electronics and POSCO,
paid off. Samsung's technological lead in semiconductors has allowed it to stake
out significant market share, while POSCO's manufacturing efficiency allowed it
to remain one of the lowest-cost steel producers in the world. Both companies
embraced President DJ Kim's efforts to restructure the economy by retiring
excess capacity and reducing labor forces.
 
During the second quarter of 1998, the benchmark index returned -24.6 percent
versus the Fund's return of -22.6 percent. The continued slide in the yen forced
additional pressure on the Hong Kong to U.S. dollar peg, which translated into
higher interest rates in Hong Kong. Because the Hong Kong stock market is
dominated by interest rate sensitive counters such as property and banking
shares, the higher rates led to a decline of the overall market.
 
In Malaysia, the market's decline was led by companies with highly leveraged
balance sheets and uncertain cash flows, as well as the banks that had made the
loans to these companies. The Portfolio was concentrated in consumer-orientated
stocks such as Rothman's and Nestle, which have dominant market share and the
ability to pass along price increases directly to the consumer.
 
The overall market in Taiwan was hit hard by weakness in the electronics sector,
with overcapacity weighing particularly heavily on semiconductor stocks.
Component companies that have strong relationships with multinationals, such as
portfolio stalwarts Compal and Asustek, held up well in the downturn.
 
The effect of the fallout in the regional markets began to pervade the real
economy. The period was marked by corporate collapses and layoffs, which caused
many of the economies to descend into economic recessions and, in some
countries, political and social unrest.
 
The inability of the Japanese government to address the looming disaster in its
financial sector, and the corresponding depreciation of the yen against the U.S.
dollar, weighed heavily on the Asian markets. Combined with tepid demand from
the Japanese consumer, the weak yen led to a sharp reduction of Asian exports
into Japan. The Japanese banks, which had built up enormous exposure to Asian
corporate debt during the last decade, have begun calling in their loans at a
rapid level, further contributing to the liquidity crunch haunting the region.
 
Although we retain the view that the Chinese government will not devalue the
yuan (and consequently the Hong Kong dollar) in the short term, there are
increasing pressures in China. The competitiveness of Chinese exports has been
undermined by the regional currency depreciations, with forthcoming consequences
for both the level of exports and the profitability of the export sector.
Imports in China have gained significant ground at the expense of domestic
companies. The effect of a yuan devaluation in the near term would be negative
for Asia, most likely resulting in the Hong Kong to U.S. dollar peg breaking and
a further round of devaluation throughout the region.
 
The slowing Chinese economy is one factor that is likely to force a further
deterioration of the Hong Kong economy. Reported GDP growth in the first quarter
of 1998 was -2 percent, while unemployment jumped to 3.5 percent. The
destruction of wealth in property and equities, as well as the steep decline in
tourism, has forced retail sales down more than 10 percent in the first quarter
of 1998. This deflation, combined with high interest rates, is a lethal mixture
for the property sector, which has decreased in value 40 percent. The effect of
difficulties in the real estate sector will continue to be severe for the
overall Hong Kong economy.
 
Accurate forecasts of Indonesia's growth have become even more difficult since
the departure of longtime leader Suharto. Although the riots and demonstrations
have subsided, distrust of the government remains. Moreover, the rupiah
depreciation, combined with a drought brought on by El Nino, indicate that
simply feeding the country's 200 million people could prove to be difficult. The
situation is exacerbated by the flight of many of the ethnic Chinese, who
dominated the Indonesian economy but were targeted for racial attacks during the
riots earlier this year. Inflation is also becoming a serious problem, to add to
the country's ills. Despite extremely cheap valuations, the macroeconomic and
political risks in Indonesia remain immense.
 
Korea, however, has taken the lead in confronting its problems and attempting to
work through its version of the Asian financial crisis. The country's Financial
Supervisory Commission, composed of a mixture of leaders from the public and
private sectors, has set an aggressive timetable for dealing with financial
sector reform and corporate restructuring. The government has also built up more
than $40 billion in foreign reserves, while the Korean current account surplus
has reached $23 billion. Though immense problems remain in the economy, the
first steps have been taken to address these issues.

(CONT.)
 
Before Asia's financial crisis can end, countries of the region must directly
address the failures in their own economies. Although the problems in Japan have
proved to be the most recent catalyst, it is important to note that the
situation in Asia, and the seeds of its eventual recovery, are based within the
countries themselves. The IMF has instituted an initial cleansing of the banking
systems in the countries under its care, but a great deal of work needs to be
accomplished domestically as well.
 
On a stock-specific basis, we will continue to focus our investments in well-run
companies that are in nonfinancial businesses, and whose management has
consistently achieved high returns on equity. Companies with irreplaceable
franchises, world-competitive technology, and strong links with multinationals,
as well as those that do not require external financing will have the capability
and the opportunity to reap the rewards of the devastated Asian markets.

In accordance with SEC regulations, Fund performance since inception as shown at
left assumes that: the maximum sales charge was deducted from the initial
investment of $10,000 in Class A shares; all recurring fees (including
management fees) were deducted; and all dividends and distributions were
reinvested. The graph presents the performance of Class A and Class C shares
which have been in existence since the Fund's inception. The performance of
Class B shares will vary based upon the different inception date and the sales
charge and fees assessed to that Class.
PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE PERFORMANCE.

For the 12 months ended June 30, 1998, the Van Kampen Emerging Markets Fund had
a total return of -34.31 percent for the Class A shares at net asset value, as
compared to a total return of -38.58 percent for the IFC Global Total Return
Composite Index for the same period.
 
The currency crisis that began with the devaluation of the Thai baht on July 2,
1997, set off a selling panic that left most Asian equity markets down as of
year-end 1997. The crisis also negatively affected markets with fixed currency
regimes and fiscal or current account deficits, such as Brazil. In the aftermath
of the crisis, we began easing into Asia during the second half of 1997, given
our belief that the currency and stock markets had dramatically overshot
fair-value benchmarks. At the time, Asian markets were down 70 percent to 85
percent from their highs, and we felt that at such levels investors had
discounted a good deal of the economic devastation wrought by corporate
bankruptcies. While we felt that the near-term economic and earnings outlook for
Asian countries was grim, and that economic pain with its commensurate political
convulsions was to be expected (particularly in Korea and Indonesia), we
believed that many of these markets represented compelling value. In the face of
negative sentiment, we expected that any marginally positive news could ignite a
huge rally in the region.
 
Events of the first quarter of 1998 bore out our expectations, as both Thailand
and Korea experienced significant positive performance in the aftermath of
public restructuring and reform.

                              INVESTMENT OVERVIEW   (CONT.)
 
DURING THE FIRST QUARTER, THE THAI AND KOREAN MARKETS WERE UP 43.4 PERCENT AND
59.1 PERCENT, RESPECTIVELY. ALTHOUGH THESE MARKETS HAVE TRADED DOWN IN THE
SECOND QUARTER OF 1998, THEY STILL REPRESENT, IN OUR OPINION, THE BEST
INVESTMENT OPPORTUNITIES IN ASIA. ELSEWHERE, INVESTORS HAVE BEEN UNFORGIVING. IN
MARKETS WHERE MOMENTUM IS PERCEIVED TO BE SLOWING, EQUITIES HAVE BEEN PUNISHED.
FOR EXAMPLE, RUSSIA DECREASED 59.3 PERCENT DURING THE FIRST HALF OF 1998, WHILE
MEXICO DECREASED 22.2 PERCENT, AND TURKEY DECLINED 14.3 PERCENT.
 
In Latin America during the first half of 1998, we increased our Argentine
exposure by approximately 2 percent, to a market-weight position. This increase
was driven by signs of economic strength and the government's commitment to
reform. We decreased our Brazilian holdings by 2 percent, bringing us to a
market-neutral position. While Brazil offers attractive value and growth
opportunities on a stock level, it suffers from deteriorating macro variables,
such as a widening fiscal deficit and a vulnerable currency. In Argentina and
Brazil, we are focusing on the telecom sector, given its strong operating
earnings growth and privatization potential. While we remained underweight, we
increased our Mexican exposure by 1 percent during the month of April. Our
underweight position in Mexico is driven by deterioration in the country's macro
environment, including a worsening trade account and expectation for higher
inflation and interest rates. Given the continued fiscal strength of the Mexican
consumer, we are focusing on such consumer-related industries as beverages and
retailers.
 
The Asian markets, driven by declines in Thailand (down 32.0 percent), Indonesia
(down 57.9 percent), and Malaysia (down 30.1 percent), plunged 22.4 percent
during the first half of 1998. The best performing Asian market for the period
was Korea, up 5.6 percent. The abysmal returns for Asia were a result of renewed
fears that currencies in the region would be devalued again based on currency
instability in Japan and Russia. Investors also were troubled by reports of
widespread nonperforming bank loans, as well as rising interest rates,
inflation, and unemployment within Southeast Asia. The most notable political
event took place in Indonesia, where President Suharto resigned in May after
leading the country for 32 years. Vice President Habibie replaced him (to the
dismay of many student protesters) and has pledged new general elections next
year. We expect that Habibie will be in office on a transitional basis.
 
The equity markets of the Indian subcontinent plummeted, with India and Pakistan
falling 15.8 percent and 58.2 percent, respectively, during the first half of
1998. Both markets toppled in the aftermath of nuclear tests, which sparked
renewed tension in the region and economic sanctions from the United States and
Japan. We had viewed these markets as offering good value and growth potential.
However, with the announcement of a disappointing budget on June 1, we have
begun to trim our overweight position in India.
 
Equity markets in Europe, the Middle East, and Africa posted widely disparate
returns. The laggards included Russia (down 59.3 percent) and South Africa (down
14.2 percent). Meanwhile, Greece was the star performer of this region,
returning 44.9 percent through June 30. Russia's equity market was devastated in
the first half of the year due to political changes, pressure on the currency,
and the decline in oil prices. At the end of March, President Yeltsin dismantled
his cabinet in a successful effort to remove then-Prime Minister Chernomyrdin.
Yeltsin assembled his new team headed by Prime Minister Kiriyenko, who had
previously been the Fuel and Energy Minister. In the short-term, sentiment
deteriorated as fears over currency instability forced the central bank to hike
interest rates by more than 100 percent. On a positive note, expectations of an
IMF package for the ailing economy are widespread and should be supportive of
the market and currency.
 
South African stocks fell 23.3 percent in June, while the currency declined 15.7
percent versus the U.S. dollar. A weak supply of foreign currency reserves left
the government unable to ward off increasing pressure on the currency, as
speculators sensed vulnerability. A lack of consistency in implementing monetary
policy led to a loss of confidence in the South African central bank. The
central bank continued to tinker with overnight repurchase rates throughout the
month, only to induce more pessimism regarding the short-term future of the
South African market. Ongoing structural problems in wages (which remain high in
real terms), weaker dollar commodity prices, and low economic growth conspired
to create an overvalued rand versus Asian currencies, further eroding the
competitiveness of South African companies.

                              INVESTMENT OVERVIEW   (CONT.)
 
During the second quarter of 1998, we entered the Greek market, with 2 percent
exposure, given our expectation for improving macroeconomic numbers as the
country prepares to join the European Monetary Union. We moved to an overweight
stance on Hungary as a result of improving economic growth and declining
inflation. Though still overweight, we decreased our exposure to Russia by 2
percent as interest rates rose to astronomical levels. Finally, while
maintaining our underweight position, we increased our exposure to South Africa
by 3 percent where we are focusing on the corporate restructuring story.
 
The spectacular bust in Asia and the bear market in emerging countries have
heightened the importance of resolving the issues plaguing these markets. In our
view, investors are passing judgment that capitalism without democracy is
fundamentally flawed, and they are demanding politically open systems, which
encourage the free flow of information of all kinds. This free flow of
information is ultimately the best natural "regulator" in the world. A free
press, full and frequent disclosure by corporations, government agencies, and,
in particular, the banking system is vital for vibrant and effective economic
functioning.
 
We believe that one of the most critical factors in the modernizing equation for
poor countries, particularly democracies, is the specter of mass unemployment.
Economic liberalization dramatically increases efficiency and is fundamentally
deflationary in its early stages. Japan, Asia, and Russia are in the throes of
such an adjustment, and Latin America (particularly Mexico) is in the early
stages of recovery from a similar transition. In truly impoverished countries,
unemployment is more than a statistic and a political inconvenience. Social
safety nets are crucial in countries with high illiteracy and low labor
mobility. Mass privatizations are critical, not only in increasing efficiency
and accountability in large parts of the economy, but also as an important
source of funding for social security and unemployment benefits.
 
At the micro-economic level, a focus on shareholder values needs to replace the
idea of old-style "Asian values," in which businesses were run by overweening
politicians and ministries in the "national interest." In today's world of low
and declining tariffs, intense global competition, and readily available
information, corporate survival will increasingly depend on producing better-
quality goods and services at lower prices. We believe the corporate largesse
engendered by the corrupt nexus between politics and big business must end.
Increasingly, the ability to extract earnings from assets that exceed their cost
of capital will be key. Developing countries will have to focus on nurturing and
producing a professional cadre of businessmen who can steer family-operated
empires in a more competitive global landscape. Education at the management and
employee level will be critical, otherwise increases in technologically driven
productivity, primarily in the West, will erode one of the important competitive
edges of the emerging markets--cheap and plentiful labor.
 
To summarize, we believe there are several important lessons to be learned from
the Asian currency crisis:
 
    - Consistency in fiscal, monetary, and currency policy is crucial.
      Inconsistency is brutally punished.
 
    - Banking systems are the heart of an economy and must be carefully and
      rigorously supervised.
 
    - Bankruptcy laws are crucial cleansing solvents, and must be clearly stated
      and enforced.
 
    - Return on equity must exceed the cost of equity. Prices of both must be
      clear; shareholder and property rights must be respected in the capital
      market and in the boardroom.
 
    - Deregulating capital markets without deregulating domestic industry is a
      disastrous combination.
 
With Asian stocks down by as much as 90 percent, we believe that the region's
equity markets are at least approaching a trough and that an economic
breakthrough in Asia is also relatively close at hand. However, the size and
speed of the recovery will depend on the ability of Asian leaders to recognize
and resolve the issues mentioned earlier. As the period ended, a Japanese
yen-driven

panic led to a second round of volatility in Asia. Nonetheless, the early
indications are that Korea and Thailand in particular are starting to transform.
Both countries have new political leadership, which should foster needed
readjustments. With the equity market down 95 percent and Suharto ousted, it is
easy to say that the worst is over in Indonesia. In reality, however, the repair
work to construct a free-market economy and a functioning democracy will be long
and painful. The ability of Russia and China to adapt to economic recessions and
the intense pressure to devalue are important factors that have yet to play out.
 
The markets are in an unforgiving mood, having driven China and Hong Kong down
50 percent and Russia down 70 percent. There may be worse economic and political
news ahead, particularly if the Japanese mandarins don't become more realistic
in their assessment of the country's economic woes. We believe, however, that
the death knell to socialism's last and true champions has been struck and the
evidence indicates that Darwinian adaptation is underway. Stock buybacks in
Japan, chaebol asset sales in Korea, bankruptcy law formulation in Thailand, and
the passage of social security reform in Brazil are perhaps the first drops of
rain after the long drought.
 
Asset valuations are near bargain levels. Investor sentiment is the most
depressed that we have seen, and early signs of restructuring is evident across
several markets. Yen stability and some decisive action by Japan to end its
crisis of confidence will most likely be the catalyst that arrests the current
free fall in sentiment and prices. We are aligning our portfolios toward
countries and companies that are demonstrating hardheaded adaptability to the
new environment we envision.

In accordance with SEC regulations, Fund performance since inception as shown at
left assumes that: the maximum sales charge was deducted from the initial
investment of $10,000 in Class A shares; the maximum deferred sales charge was
deducted from the value of the investment of $10,000 in Class B and Class C
shares; all recurring fees (including management fees) were deducted; and all
dividends and distributions were reinvested.
PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE PERFORMANCE.
 
The investment objective of the Van Kampen Global Equity Fund, formerly known as
the Morgan Stanley Global Equity Fund, is to seek long-term capital appreciation
by investing primarily in equity securities of issuers in developed markets
throughout the world, and in emerging markets on an opportunistic basis.
 
For the period from the inception of the portfolio on October 29, 1997, through
June 30, 1998, the Fund generated a total return of 12.21 percent for Class A
shares at net asset value, as compared to a total return of 20.12 percent for
the Morgan Stanley Capital International (MSCI) World Index for the same period.
 
The Fund's underperformance in 1998 was almost entirely due to weak relative
performance from U.S. stock selection, particularly in the second quarter. It is
also clearly reflective of the fact that the U.S. market is being driven to
record levels by macro-cap names such as General Electric and Coca-Cola
respectively trading at 35 times and 53 times trailing earnings. As value
investors, we are loath to pay such premiums in what seems to be a flight to
(apparent) quality.
 
Several of our U.S. stocks were hurt, however, by specific events that we
believe caused them to be oversold. Borg Warner (BWA), for example, the auto
components manufacturer, fell 24 percent during the quarter because of Asian
fears (20 percent of sales) and production delays within Ford, which produces 20
percent of BWA's sales. The oil stocks, Noble Drilling, and Ocean Energy,
continue to be affected by weakness in the price of oil. Philip Morris, one of
our largest holdings, fell 4 percent amid continuing litigation worries. We
expect, however, some shareholder-friendly measures to be announced by the
company during the second half of the year.
 
THE COUNTRY-SPECIFIC PERFORMANCE RESULTS PROVIDED IN THIS OVERVIEW ARE AS
MEASURED BY THE MSCI
WORLD INDEX AND ARE FOR INFORMATIONAL PURPOSES ONLY AND SHOULD NOT BE CONSTRUED
AS A GUARANTEE OF THE FUND'S FUTURE PERFORMANCE. INVESTMENT RETURN AND PRINCIPAL
VALUE WILL FLUCTUATE SO THAT AN INVESTOR'S SHARES, WHEN REDEEMED, MAY BE WORTH
MORE OR LESS THAN THEIR ORIGINAL COST. PLEASE SEE THE PROSPECTUS FOR A

                              INVESTMENT OVERVIEW   (CONT.)
 
Stock selection in Italy and Germany was also a negative contributor during the
second quarter. Telecom Italia fell 20 percent, while in Germany, Veba was
affected by the departure of its Chairman. On a positive note, stock selection
in Switzerland and the Netherlands was particularly strong and our underweight
positions in Japan and Southeast Asia continue to benefit the portfolio.
 
New additions to the portfolio during the period included Groupe Danone, Chase
Manhattan, and Richemont. Groupe Danone is France's largest brewer of beer, the
world's second-largest producer of mineral water, and is number one in the
European dairy-products market. Though the company has problems in its biscuit
and pasta business, management is committed to turning these around. Danone has
a low level of maintenance capital expenditure and generates strong free cash
flow.
 
Chase Manhattan provides domestic and international financial services, and has
virtually completed nationalizing two of the largest mergers in U.S. banking
history. It is the leading player in the corporate loan syndication business and
has weakened recently due to concerns over its emerging markets exposure. Chase
should be able to grow earnings at a double-digit rate, and use excess cash to
buy back 3 to 4 percent of its stock.
 
Richemont is the Swiss holding company for Rothman's International, the
fourth-largest international tobacco group, and Vendome Luxury Group, whose
brands include Cartier, Alfred Dunhill, and Montblanc. On the negative side, the
Rupert family owns just 10 percent of the equity but controls 50 percent of the
voting stock in Richemont. However, the Ruperts have a good track record of
creating and nurturing cash-generative consumer franchises.
 
Given a remarkably strong first half of the year in Europe, robust returns in
the United States, and sustained weakness throughout Asia, it is somewhat
difficult to predict the second half of 1998. The U.S. market's current
fascination with Internet stocks seems to indicate an unhealthy optimism while,
it is important to note, earnings expectations for the balance of the year
remain overly optimistic. Continental Europe provides the only environment where
both corporate profits are accelerating and interest rates are likely to remain
low. While Asia's travails are slowing the pace of recovery we do not expect
even the capital goods dependent economy of Germany to stagnate. However, stock
markets have not been slow to discount this environment and multiples are high,
although European markets generally remain more attractive than the United
States on price-to-book value and price-to-cash flow multiples. The extent of
earnings disappointment from Asia will be the key driver of the second half,
although companies in both Europe and the United States typically generate less
than 10 percent of their sales there. Money flows, merger and acquisition
activity, and interest rates should remain supportive in the near term.
 
We decreased our U.S. weighting during the period as some of our U.S. stocks
have reached their fair-value targets and we strive to add more defensive names.
We would expect to continue our underweight in the United States, with selected
overweights in Europe. Despite regular visits from our analysts--and absent
fundamental reform--we struggle to find catalysts that will unlock what
increasingly appears to be relative value in Japan, and the risk in Southeast
Asia continues to outweigh the potential return.

In accordance with SEC regulations, Fund performance since inception as shown at
left assumes that: the maximum sales charge was deducted from the initial
investment of $10,000 in Class A shares; all recurring fees (including
management fees) were deducted; and all dividends and distributions were
reinvested. The graph presents the performance of Class A and Class C shares
which have been in existence since the Fund's inception. The performance of
Class B shares will vary based upon the different inception date and the sales
charge and fees assessed to that Class.
PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE PERFORMANCE.

The Van Kampen Global Equity Allocation Fund, formerly known as the Morgan
Stanley Global Equity Allocation Fund, seeks long-term capital appreciation by
investing primarily in equity securities of U.S. and non-U.S. issuers in
accordance with country weightings determined by the subadviser and with stock
selection within each country designed to replicate a broad market index. As
such, emphasis is placed upon country rather than stock selection. This approach
reflects our investment philosophy that a diversified selection of securities
representing exposure to each country that we find attractive is an effective
way to maximize the return and reduce the risk associated with global investing.
 
For the 12 months ended June 30, 1998, the Van Kampen Global Equity Allocation
Fund generated a total return of 16.17 percent for the Class A shares at net
asset value, as compared to a total return of 17.03 percent for the Morgan
Stanley Capital International (MSCI) World Index.
 
The MSCI World Index performed strongly in the year ended June 30, 1998, and was
marked by the continuing strong performance of the United States and Europe and
the sharp declines of Japan and Asia. Buoyed by strengthening economies and
increasing euphoria about the approaching economic and monetary union, stock
markets in Europe led with a 37 percent
 
THE COUNTRY SPECIFIC PERFORMANCE RESULTS PROVIDED IN THIS OVERVIEW ARE AS
MEASURED BY THE MSCI WORLD INDEX AND ARE FOR INFORMATIONAL PURPOSES ONLY AND
SHOULD NOT BE CONSTRUED AS A GUARANTEE OF THE FUND'S FUTURE PERFORMANCE.
INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE SO THAT AN INVESTOR'S
SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST.

                              INVESTMENT OVERVIEW   (CONT.)
 
RETURN (IN U.S. DOLLARS). THE UNITED STATES RETURNED 30 PERCENT WITH STRONG FUND
FLOWS AND OPTIMISTIC EARNINGS FORECASTS SUPPORTING EQUITIES. CONVERSELY, JAPAN
AND THE REST OF ASIA FELL DRAMATICALLY, RETURNING -32 PERCENT AND -44 PERCENT,
RESPECTIVELY. THE JAPANESE ECONOMY MOVED INTO RECESSION AND GOVERNMENT POLICY
FAILED TO RESPOND WHILE THE CRISIS IN ASIA BROADENED AND DEEPENED.
 
During the reporting period, the single largest contributor to the portfolio's
relative outperformance was our significant underweight positions in Japan, Hong
Kong, Singapore, and Malaysia. We continued to underweight the United
States--the largest market in our investment universe--which detracted from
performance. Our overweight allocation to Europe, which we increased during the
year, was positive and the portfolio benefited, especially from overweight
positions in Italy and Spain. A slight overweight to the United Kingdom and
underweight to Finland detracted from portfolio results. Hedging most of our
Japanese yen exposure was constructive as the U.S. dollar appreciated against
the yen, while hedging a portion of our deutsche mark bloc exposure was broadly
neutral for portfolio returns.
 
Recently, we made several minor allocation adjustments in countries, sectors,
and currencies, gradually increasing our cash as further evidence developed of
the depth of the economic problems in Japan, Asia, and other emerging markets
such as Russia and South Africa.
 
We are concerned about U.S. equity valuations and market levels. Though
supported by continued liquidity, strong money growth, and record consumer
sentiment, some of the underpinnings of this bull market are weakening.
Specifically, earnings downgrades and momentum are negative and returns on
equity have moved well below peak. Forward earnings versus bond yields are back
at levels seen in the summer of 1997. Priced for perfection, we feel that there
is little room for disappointment. We remain underweight relative to our
benchmark.
 
We remain overweight in European equities, particularly the so-called
"Euro-bubble" countries. We still believe that the European stock markets are
the best place to be in an equity world that is generally both frothy and
expensive.
 
In 1998, after the glorious surge of the first three months of the year, the
second quarter was either the pause that refreshes--a period of consolidation as
the technicians would say--or a broad top formation. Frankly, we aren't quite
sure which, but if actions speak louder than words, our cash position is
definitely on the high side.
 
We have benefited from our long-held strategy of being overweight in Europe and
underweight in Japan, the yen, and the rest of Asia. Within Europe, our heavy
allocations to Italy and Spain that served us so well in the first quarter were
less fruitful, as the stock markets of Germany and France, where we were
modestly overweight, assumed leadership.
 
At this point, we are not inclined to alter our fundamental positions. There is
a lot of turbulence and random noise, but the underlying environment is that the
U.S. economy and dollar are strong, Europe is recovering, and Asia is sick.
Stock markets are discounting mechanisms so we must be alert that change at the
margin is not occurring.
 
With this in mind, we visited Asia in April and spent three days in Japan. We
met with investors, businessmen, the Bank of Japan, the Ministry of Finance, and
a senior leader of the LDP. We found good manners and some charm but nothing to
cheer us. Has there been positive change at the margin in Japan? Maybe a little,
but the problems are so dire and confidence so low, that dramatic solutions
which alter sentiment are needed. Instead, we feel the government tries to fool
the markets with talk and halfway measures. The bridge bank proposal is a step
in the right direction, but details are lacking and it will take years to play
out; it is not a market-clearing solution. The politicians' vacillation on tax
cuts is pathetic, and the markets are tiring of it.
 
We still believe Japan's equity market is expensive, its economy a disaster, and
its political institutions remain in full denial of the seriousness of the
predicament that the country is in. We are actually more bearish on the yen than
the stock market, and our approximately 40 percent of the index weight in Japan
is 90 percent hedged back to the dollar.

                              INVESTMENT OVERVIEW   (CONT.)
 
We believe the rest of Asia is not in a recession but a depression. Visits to
Hong Kong and China confirmed this, as did the New York visit with the Finance
Minister of Malaysia. We eliminated our position in Hong Kong, which turned out
to be felicitous. The problems of Asia have been dissected ad nauseam, but in
summary we believe it is too soon to make a serious investment commitment.
 
Europe still looks like the place to be because of its economic cycle and
because of Economic and Monetary Union (EMU) and its accompanying euphoria.
Recent visits to both Spain and Italy confirmed our conviction that these two
markets are the essence of the so-called "Euro-bubble" concept.
 
There is still a lot of skepticism about EMU, and some very smart people believe
that it won't work in the long run. We say baloney! We say it will work and the
surprise may be how successful it is. The Euro-bubble markets should be the
prime beneficiaries. The realpolitik of Euroland requires that the new European
Central Bank must converge interest rates at a low enough level to sustain
growth in the slower-growing core countries where unemployment is still very
high, even if this means that the faster growing fringe economies overheat. The
elite that has stage-managed EMU so adroitly simply cannot take the chance that
the French and German economies falter in the first year of EMU.
 
We are continuing to put a lot of effort into sector research. We maintain our
emphasis on financial stocks across Europe. In Italy we heard repeatedly how the
banks and insurance companies are benefiting from low interest rates and strong
fund flows. We added a tilt into European oil stocks during the second quarter,
which we have profitably unwound, and we are currently buying a broad cross
section of European real estate securities.
 
Commercial property prices across Europe are still very depressed, but we
believe the cycle is about to turn, as do local experts and our sources in
Morgan Stanley's real estate group. Already rents are beginning to firm, and
many of the stocks are selling well below both net asset values and replacement
costs of the underlying assets.
 
In conclusion, we are carefully watching markets and economic events. The risk
is that Asia undermines the Western economies, and indeed there are a few early
signs that both the United States and Europe are slowing. If so, earnings will
be disappointing but interest rates will fall again. Will equity markets go down
under such circumstances? In our opinion, it depends on how severe the earnings
shortfall is. We do believe that international portfolios will outperform U.S.
equities in this environment.

In accordance with SEC regulations, Fund performance since inception as shown at
left assumes that: the maximum sales charge was deducted from the initial
investment of $10,000 in Class A shares; all recurring fees (including
management fees) were deducted; and all dividends and distributions were
reinvested. The graph presents the performance of Class A and Class C shares
which have been in existence since the Fund's inception. The performance of
Class B shares will vary based upon the different inception date and the sales
charge and fees assessed to that Class.
PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE PERFORMANCE.

The Van Kampen Global Fixed Income Fund, formerly known as the Morgan Stanley
Global Fixed Income Fund, seeks to produce an attractive real rate of return by
investing in fixed-income securities of U.S. and foreign issuers denominated in
U.S. dollars and in other currencies.
 
For the 12 months ended June 30, 1998, the Van Kampen Global Fixed Income Fund
achieved a total return of 5.36 percent for the Class A shares at net asset
value. By comparison, the J.P. Morgan Traded Global Bond Index returned 5.87
percent during the same period.
 
The Asian economic crisis and the resultant weakness in world trade and
commodity prices combined to provide an attractive environment for global bonds
during the 12-month period. As secondary negative macroeconomic shocks appeared
within the Asian countries during recent months, growth expectations for the
region in general and Japan specifically, have been further reduced. While the
effect of growth in the United States and Western Europe has been mitigated by
the strength of the domestic economies to date, expectations are for a broader
downturn in the second half of 1998. The anticipated slowdown of growth in the
United States and Europe, coupled with a general flight to quality from the
emerging markets, resulted in all global fixed income markets producing solid
local currency returns.
 
In the United States, 10-year yields fell 99 basis points (0.99 percent) as
Treasuries gained on dollar strength, benign inflation data, and the belief that
any raising of interest rates by the Federal Reserve was on hold. The core
European markets also performed well and 10-year yields fell 70 to 90 basis
points (0.7 to 0.9 percent) as the lower inflation outlook led to a further
downgrading of

PERFORMANCE. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE SO THAT AN

INTEREST RATE EXPECTATIONS. WITHIN EUROPE, THE CONTINUED MOVE TOWARD MONETARY
UNION WAS ALSO A DOMINANT THEME WITH THE RELEASE OF VARIOUS EUROPEAN CONVERGENCE
REPORTS IN THE FIRST QUARTER OF 1998 CONFIRMING THE START OF MONETARY UNION WITH
11 QUALIFYING COUNTRIES. THIS FOCUS WAS REFLECTED IN THE CONVERGENCE IN YIELDS
OF EUROPEAN PERIPHERAL MARKETS TOWARD THOSE IN GERMANY, AS ITALIAN, SPANISH, AND
IRISH BONDS ALL RALLIED STRONGLY. THE ITALIAN MARKET WAS THE BEST PERFORMING
MARKET GLOBALLY, WITH 10-YEAR YIELDS FALLING 174 BASIS POINTS (1.74 PERCENT)
VERSUS A 137 BASIS POINT (1.37 PERCENT) MOVE IN THE SPANISH AND IRISH MARKETS.
ATTENTION SHIFTED TO THE COUNTRIES THAT MAY BE PART OF THE SECOND STAGE OF
EUROPEAN MONETARY UNION, AND 10-YEAR YIELDS IN SWEDEN, THE MAIN BENEFICIARY,
FELL 163 BASIS POINTS (1.63 PERCENT). IN THE UNITED KINGDOM HOWEVER, 10-YEAR
YIELDS FELL ONLY 116 BASIS POINTS (1.16 PERCENT) AS BONDS SUFFERED IN RESPONSE
TO HIGHER-THAN-EXPECTED INFLATION DATA AND FOUR INCREASES IN THE BASE RATE
DURING THE PERIOD. IN JAPAN, THE DETERIORATION OF THE ECONOMY TO NEARLY
DEPRESSION-LIKE CONDITIONS, COUPLED WITH INVESTOR SKEPTICISM ABOUT THE
GOVERNMENT'S COMMITMENT TO FISCAL STIMULUS, CONTINUED TO SUPPORT THE BOND
MARKET. AS A RESULT, 10-YEAR YIELDS FELL 100 BASIS POINTS (1 PERCENT).
 
Global returns in U.S. dollars were reduced because of general dollar
appreciation during the period. The largest move was versus the Japanese yen,
against which the U.S. currency rose a massive 17.5 percent. The Australian
dollar was almost equally soft, falling 17.3 percent versus the dollar, as the
proximity of Australia to Asia appeared to further the correlation of the
Australian dollar with the yen. The U.S. dollar generally appreciated a more
moderate 3 to 7 percent against the European currencies. The sterling, however,
gained just more than 1 percent against the dollar, supported by the strength of
the U.K. economy and the 1-percent rise in the base rate during the period.
 
Contributory factors to the performance of the Fund were the overweight position
during the period to the higher-yielding European markets and to the U.K. and
Irish markets. Our underweight exposure to the Japanese yen was also a positive
factor, but our cautious approach to duration overall, and to the Japanese
market in particular, were negative factors.
 
Strategy changes in the second half of 1997 included reduced exposure to
Japanese bonds, with proceeds placed in the Australian market. We also purchased
a position in a 5-year U.S. Treasury inflation-protected security, taking
advantage of the attractive levels of real yields. In 1998, the most significant
shift in exposure has been a further extension in our underweight position in
Japanese bonds during June. This shift was in response to our concern that
investors may start pricing in a higher-risk premium for Japanese assets. We
placed proceeds in the dollar bloc and European bond markets, taking our
interest rate exposure in both regions to an overweight position and our overall
portfolio exposure to neutral. This was consistent with our more negative
interpretation of the Asian crisis. An underweight position in Japanese yen was
maintained throughout the 12-month period. However, following the Federal
Reserve's June intervention in the currency markets to support yen to dollar, we
reduced our underweight position to approximately 5 percent.
 
We believe that Japan and the level of the Japanese yen are now key to any
recovery within the Asian economies. We remain, however, unconvinced of the
Japanese government's commitment to providing any near-term effective stimulus
to its economy. While talk of permanent tax cuts and a "bridge bank" scheme are
positive, investors need clearer indications of policy implementation. It is
difficult to predict what will happen in Japan and Asia. However, on balance, we
feel that the Asian crisis, and its negative implications for global growth,
will continue. These fundamentals should continue to support global bonds and
also to sustain the ongoing flight to quality from the emerging markets.
Consequently, we are positive on global bond markets--with the exception of
Japan. However, caution is also required, as U.S. bond yields are at their
lowest level since 1993, and Japanese and European yields are also at all-time
lows. It is difficult to justify extending interest rate exposure unless we
expect economic conditions globally to worsen from the already negative scenario
priced into the markets. We are, therefore, in an overall position of neutral in
interest rate exposure, and expect bonds to remain a good performing asset class
during the remainder of the year.

The investment objective of the Morgan Stanley Government Obligations Money
Market Fund is to provide a high level of current interest income consistent
with maintaining liquidity and stability of principal. It seeks to achieve this
objective by investing in short-term U.S. Treasury bills, notes, and other
obligations issued or guaranteed by the U.S. government, its agencies, or
instrumentalities, and entering into repurchase agreements relating to such
obligations.
 
The annualized seven-day yield and seven-day effective yield (which assumes all
dividends are reinvested) for the Government Obligations Money Market Fund as of
June 30, 1998, were 4.19 percent and 4.28 percent, respectively. As with all
money market portfolios, the seven-day yields are not necessarily indicative of
future performance.
 
The U.S. economy began 1998 with a robust first quarter, as indicated by a GDP
growth of 5.4 percent. This level represented a healthy pace of economic growth.
Inflation at the CPI level was nonexistent, as commodity and producer prices
fell during the first quarter. Interest rates also declined; as a result,
consumers enjoyed attractive financing, which stimulated a strong housing
market. Jobs remained plentiful and the unemployment rate held steady at 4.7
percent.
 
As we moved into the second quarter, economic strength continued, although at a
more moderate pace. The labor market made further gains, and the unemployment
rate fell to 4.5 percent. Wages rose in the second quarter, although not enough
to trigger market fears of higher inflation and tighter corporate profit
margins. Wage growth continues to be one of the key elements in defining the
expansion's life cycle. As long as wages grow at a gradual pace, the current
balance between low inflation and healthy corporate profits can remain intact.
 
By the end of the second quarter, interest rates had fallen to their lowest
levels of the year. The U.S. Treasury curve was flat to inverted, and the yield
on the long bond had fallen to 5.626 percent. Low domestic inflation played a
large part in driving interest rates lower, as did the economic and fiscal
crisis in Asia. Asian pressures helped increase foreign demand for U.S. bonds,
as foreign investors sought out higher-quality markets in which to invest and
protect their capital.
 
Typically, in situations where the economy is as strong as it is in the United
States, markets would become concerned that monetary policy might turn more
restrictive in order to slow economic growth and prevent inflation. Although
these concerns exist, the markets are less concerned that the Federal Reserve
Board might raise interest rates to slow economic growth because other
regulating factors exist. While the Asian crisis has helped to drive bond prices
higher, it has also widened the trade deficit, and may provide a slowing effect
on our domestic economy. The strength of the dollar will also have a similar
effect, as foreign demand for U.S. exports will decline and slow U.S. output.
There is concern that U.S. businesses have built up excessive inventories, which
may put corporate profit margins under pressure. If consumer demand is not
sufficient to relieve businesses of their surplus inventories, the excessive
carrying costs of unsold goods can potentially tie up capital and stall
corporate growth plans.
 
INVESTMENTS IN SHARES OF THE FUND ARE NEITHER INSURED NOR GUARANTEED BY THE U.S.
GOVERNMENT AND THERE IS NO ASSURANCE THAT THE FUND WILL MAINTAIN A STABLE NET
ASSET VALUE OF $1.00 PER SHARE. YIELDS WILL FLUCTUATE AS MARKET CONDITIONS
CHANGE.

                              INVESTMENT OVERVIEW   (CONT.)
 
Most economists have lowered their third and fourth quarter GDP estimates by 1
to 2 percent in anticipation of the above economic effects. If these economists
are correct, and the economy slows automatically, the Fed may leave monetary
policy unchanged throughout the remainder of 1998. This outcome is especially
likely if Fed Chairman Alan Greenspan persists in exercising his influence over
the other members of the FOMC.
 
Throughout the first half of the year, we invested the Fund's assets in fixed
government bills, discount notes, and floating-rate instruments. The Fund ended
the second quarter with a weighted average maturity of 51 days. Our target
maturity range has been between 50 and 60 days, reflecting our neutral
interest-rate outlook which we plan to maintain.
 
Current money market yields are very low and the yield curve offers little
protection against a potential interest rate hike by the Fed. While the market
is not expecting a Fed tightening, there is still little reason to extend our
overall maturity in the Fund. Yields in longer-dated maturities offer almost the
same return as do yields on shorter-dated maturities. We have been looking to
add more floating rate securities to the Fund to increase incremental yield
without taking undue interest rate risk. By buying floaters, we are protected
against any increase in interest rates by the Fed should they tighten early next
year.
 
We believe that while it is likely that there will be no tightening throughout
the remainder of 1998, the risks of higher interest rates remain and could be
realized as early as the first quarter of 1999. Additionally, we may experience
a steepening in the yield curve before the end of this year as markets
anticipate future monetary policy changes. Should the curve experience some
steepening, we would view the event as an opportunity to extend our average
maturity.

In accordance with SEC regulations, Fund performance since inception as shown at
left assumes that: the maximum sales charge was deducted from the initial
investment of $10,000 in Class A shares; the maximum deferred sales charge was
deducted from the value of the investment of $10,000 in Class B and Class C
shares; all recurring fees (including management fees) were deducted; and all
dividends and distributions were reinvested.
PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE PERFORMANCE.
 
The investment objective of the Van Kampen High Yield & Total Return Fund,
formerly the Morgan Stanley High Yield Fund, is to seek to maximize total return
by investing in a diversified portfolio of high-yield, high-risk income
securities that offer a yield above what is generally available on debt
securities in the four highest categories of the recognized rating services.
 
For the year ended June 30, 1998, the Fund had a total return of 10.81 percent
for Class A shares at net asset value, as compared to 10.98 percent for the CS
First Boston High Yield Index.
 
Bolstered by a favorable investing environment, the high-yield market performed
reasonably well during the reporting period. Interest rates on 10-year Treasury
securities declined about 100 basis points during the year ended June 30,
causing the 2-year to 10-year portion of the yield curve to invert slightly. The
equity market was very strong as the S&P 500 index rose over 25 percent during
the same period. The first quarter of 1998 was particularly strong for equities,
while the high-yield market also performed better in the first quarter of the
year than during the final three months of the reporting period.
 
Given the declining interest rate environment and solid economy, B-rated bonds
outperformed higher-quality issues. Longer-duration bonds also outperformed. The
lower tier and distressed sector of the high-yield sector, however, continued to
experience difficulties. From an industry perspective, retail, technology, and
utilities outperformed while auto parts, energy, and textiles lagged.

                              INVESTMENT OVERVIEW   (CONT.)
 
Our portfolio continues to benefit from a large position in Nextel. The company
has done an excellent job of adding subscribers to its network at a rapid pace.
The cable television sector also performed well, especially after TCI and AT&T
announce a merger. Our positions in Korea rebounded nicely after being very
depressed in the fall. This has been a volatile position, not only on its own
merits, but due to concerns over Asia and Russia. Our other emerging-markets
positions have been a drag on performance so far this year.
 
Widening spreads during the second quarter made the high-yield sector reasonably
attractive as the reporting period ended. Most companies continue to maintain
decent balance sheets. While the Fed appears inclined to raise interest rates
because of the strong economy and rising wage pressures, problems in Asia and
Russia--coupled with tame inflation statistics--have kept the Fed on hold. The
commodity and cyclical sectors are a concern at this point. We strive to
position our holdings in growth-oriented companies and those not impacted by
competition from Asian imports or declining commodity prices.

The Van Kampen International Magnum Fund, formerly known as the Morgan Stanley
International Magnum Fund, seeks long-term capital appreciation by investing
primarily in equity securities of non-U.S. issuers in accordance with the EAFE
country weightings determined by the subadviser. The EAFE countries in which the
Portfolio will invest are those comprising the MSCI EAFE Index, which includes
Australia, Japan, New Zealand, most Western European nations, and certain
developed countries.
 
For the 12 months ended June 30, 1998, the Van Kampen International Magnum Fund
generated a total return of 8.32 percent for the Class A shares at net asset
value, as compared to a total return of 6.10 percent for the MSCI EAFE Index.
 
June marked the end of a very turbulent year in the international markets. The
turmoil began with the devaluation of the Thai baht on July 2, 1997, and quickly
spread throughout Asia, claiming victims large and small. A year later, the
economies of Thailand, Malaysia, Indonesia, and others are on the brink of
recession, with some currencies having lost as much as 60 percent of their value
versus the dollar. Meanwhile, the weakest stock markets fell as much as 60
percent in local currency terms. No Asian market--developed or developing--has
been spared; the MSCI Emerging Markets Far East Index depreciated 65.7 percent
in U.S. dollar terms for the 12-month period ended June 30, 1998.
 
The so-called "Asian Flu" exacerbated problems in Japan, which encountered its
own bout of currency weakness. Concerns about excessive bad bank loans, a
slowing economy, and a lack of political will to confront these problems also
hurt the Japanese stock market, which fell more than 17 percent in yen terms and
more than 30 percent in U.S. dollar terms during the past 12 months.

                              INVESTMENT OVERVIEW   (CONT.)
 
The economic troubles from the Pacific Rim even sent ripples through markets as
far away as the United States and Europe, where companies such as banks and
high-tech firms with significant exposure to Asia began to feel a pinch in
earnings. Despite these selected sectors, however, the tone in both the United
States and European markets has remained positive overall. In Europe, the mood
bordered on euphoric, particularly in the first quarter of 1998. Europe's
overall exposure to Asia is low, and the continent has been focusing on its own
economic agenda: the start of the Economic and Monetary Union (EMU) in 1999.
 
The European equity markets posted a dramatic 20.3 percent rise in the first
quarter of 1998, followed by a more modest 5.1 percent gain in U.S. dollar terms
for the three-month period ended June 30, 1998. Year-to-date, the European
markets have climbed an impressive 26.5 percent in U.S. dollar terms. Investors
are bullish about EMU, which took a step closer to reality with May's
announcement of the 11 initial participant nations. Although valuations are
becoming a bit stretched, fundamentals are generally supportive. The
pan-European economy continues to strengthen and interest rates continue to
fall, particularly in higher-growth economies like Spain and Italy. Corporate
earnings are rising as companies restructure and focus more on creating
shareholder value. Flows into European mutual funds have been very strong, as
high-flying equity returns have drawn individual investors' assets from
low-yielding bank accounts.
 
In 1998, the European equity markets have been led by strong year-to-date
performances in Germany (up 36.5 percent), Finland (up 65.6 percent), and
Belgium (up 43.3 percent). Germany has been helped by EMU euphoria and improving
economic fundamentals, including lower unemployment rates and benign inflation.
Meanwhile, the gains in Finland largely reflect the strong performance of Nokia
(+125 percent), which comprises more than half of the EAFE Index. Belgium
thrived on the strength of the banking sector, as consolidation in European
financial services has boosted the sector throughout the continent. Portugal and
Italy, two of the markets that were the strongest during the first quarter,
succumbed to profit taking during the second quarter, with each falling more
than 2 percent. The United Kingdom is one of the weakest markets year-to-date,
falling 2.0 percent for the second quarter and rising only 15.7 percent year to
date, with much of the rise attributable to the strength of the pound. Tight
monetary policy has threatened to drive the United Kingdom into a recession,
while the strength of the currency has hurt exporters.
 
In sharp contrast to the gains in Europe, the MSCI Japan Index fell 4.5 percent
in U.S. dollar terms during the second quarter and declined 2.5 percent during
the first six months of the year. Market participants were disappointed by the
lack of political will to address the nation's problems, and responded by
selling both Japanese equities and the yen. For most of this decade, the
Japanese economy has been hampered by billions of dollars of bad bank loans and
the lack of a coherent and stimulative fiscal policy. Permanent tax cuts,
coupled with the creation of an institution similar to the Resolution Trust
Corporation could help solve these problems and provide an economic boost. So
far, however, the ruling party has been unwilling or unable to implement these
or other changes. Given the lack of progress, investors abandoned Japanese
assets, causing the Japanese currency to depreciate by more than 13 percent
versus the U.S. dollar and the Nikkei 225 Index to fall 11 percent in the second
quarter alone. In mid-June, during the most panic-filled moments of the sell-
off, the U.S. Federal Reserve Board and the Bank of Japan intervened in the
currency markets to support the yen. This show of solidarity gave yen-selling
speculators pause and bought policy makers a little time. However, elections in
early July handed the leading LDP party a surprising defeat and caused Prime
Minister Hashimoto to resign. As of this writing, many issues remained
unresolved, including the future leadership of the world's second-largest
economy and the nation's ability to address its economic problems.
 
Following a short-lived rally during the first quarter, the equity markets of
Asia (excluding Japan) depreciated 22.6 percent for the quarter and 17.4 percent
year-to-date in U.S. dollar terms. The markets resumed their downward trend
after it became clear a cure for the Asian Flu had yet to be found. As expected,
economic growth has fallen off substantially following last year's currency
devaluations. In Singapore, where the market fell 35.2 percent during the second
quarter, credit contracted for the first time in a decade and GDP growth is
expected to be a meager 0.5 percent. In Hong Kong (down 26.9 percent during the
second quarter), authorities postponed the real estate

auctions that provide the government with most of its revenues, choosing instead
to support real estate values that have fallen by more than 50 percent from
their highs. The markets were also rattled by comments from Chinese officials
that the free fall in the yen would need to be stopped lest China be forced to
devalue the yuan and perhaps the Hong Kong dollar to maintain competitiveness.
Devaluation in China, in turn, would lead to another round of currency
devaluations throughout the region as other export-oriented Asian nations
struggled to remain competitive with their larger neighbors. Although the threat
of such a move prompted the United States to intervene in the currency markets
to stem the yen's slide, the continued lack of stability, combined with the
dramatic fall-off in economic activity throughout the region, kept investors at
bay. Japan is Asia's engine of growth, and until its economy revives, the region
will have difficulty stabilizing.
 
The International Magnum Fund outperformed the benchmark MSCI EAFE Index during
the past 12 months due to a variety of factors. Our regional allocation
contributed to performance--we continued to reduce exposure to Asia and Japan
while increasing European holdings. Stock selection in Europe was negative, as
we were underweight in the bank and insurance sectors, which were among the
stronger performers. We benefited, however, by strong performance in our
Japanese stocks, where we concentrated on export-oriented companies. Style also
hurt performance in Europe as growth stocks outperformed our portfolio's value
stocks by a rather wide margin, particularly during the second quarter of 1998.
Our hedged exposure to the yen and the Deutschemark, both of which depreciated
versus the dollar, added to performance.
 
During the second quarter of 1998 we continued to increase the Fund's exposure
to Europe based on our belief that fears of an Asian-induced slowdown there were
overdone and that EMU would enhance growth prospects for the region. We moved
from a slightly underweight position to a slightly overweight one, such that
European holdings now make up about three-quarters of the portfolio.
 
Looking ahead, Europe appears to offer the most attractive investment potential.
Consequently, we anticipate increasing our exposure to the region. Although
valuations in Europe are extended relative to historical levels, we expect
fundamentals to remain supportive, with increased crossborder investment, share
buybacks, mergers and acquisitions, and lower interest rates all being positive
factors for equities. Furthermore, earnings expectations have bottomed and are
rising, as free cash flow has hit the highest levels in 25 years.
 
We will maintain our underweight positions in Japan and Asia pending signs of
improvement in the region. Specifically, we will carefully monitor political
developments in Japan, as the choice of a new prime minister may signal the
policies that will be implemented. We will continue to look for signs that the
bad debt crisis is being addressed, and we would view any permanent tax cut or
other stimulative policy as a positive move. Without stability and growth in
Japan, however, we believe opportunities for regional growth throughout Asia
will be limited.

The investment objective of the Van Kampen Latin American Fund, formerly known
as the Morgan Stanley Latin American Fund, is to provide long-term capital
appreciation by investing primarily in equity securities of Latin American
issuers.
 
For the 12 months ended June 30, 1998, the Van Kampen Latin American Fund had a
total return of -17.37 percent for the Class A shares at net asset value, as
compared to a total return of -24.92 percent for the Morgan Stanley Capital
International (MSCI) Latin America Global Index.
 
The Asian crisis that began July 2, 1997, with the Thai baht devaluation and its
subsequent contagion throughout the emerging markets resulted in poor
performance across all Latin markets in the last half of 1997. However, the Fund
outperformed its benchmark during the period, primarily because of strong
country allocation and stock selection. The largest contributors to the Fund's
outperformance were our overweight exposure in Mexico, underweight exposure in
Chile, increased exposure to Brazil in early December, and strong stock
selection in Mexico, where we focused on the consumer-related companies.
 
Investors punished Brazil during the second half of 1997, as its stock market
decreased 18.4 percent. Because Brazil follows a fixed exchange rate regime and
has both a large current account and fiscal deficit, superficial similarities to
Southeast Asian countries led to fears of a currency devaluation. The effect of
these fears was exacerbated by profit taking following the large gains of the
prior year. During the fourth quarter of 1997, Brazil was able to distance
itself from the focus on Asia as

                              INVESTMENT OVERVIEW   (CONT.)
 
Brazilian authorities made positive moves to support the equity market. These
moves included an aggressive, well-planned response to the crisis, including the
doubling of interest rates and a significant tightening of fiscal policy.
 
Mexico was the region's best performing market during the first half of the
period, appreciating 16.8 percent. The outstanding performance was largely due
to the recovery of the Mexican consumer, as evidenced by improving retail and
consumer production sales, and increasing real wages.
 
Elsewhere in Latin America, Argentina declined 1.4 percent during the last six
months of 1997 largely in sympathy with the overall weakness of equity prices in
the region. The Chilean market decreased 21.3 percent during the same period
because of modest profit taking during the third quarter and commodity deflation
during the fourth quarter of last year.
 
Colombia posted the second best return in Latin America, appreciating 3.3
percent during the second half of 1997. The Colombian equity market benefited
from improved sentiment as investors anticipated an end to the economic slowdown
and subsequent upturn in growth. Peru decreased 14.9 percent during the period,
largely in response to concerns over effect of El Nino on the economy, and
political instability. Weakening oil prices fueled Venezuela's 10.9 percent
decline.
 
Renewed turmoil in Asia led to continued declines in all Latin equity markets in
the first half of 1998. Overall, the Latin American region decreased 19.9
percent during the first six months of 1998, driven by returns in Venezuela
(down 45.7 percent), Brazil (down 15.9 percent), and Mexico (down 22.2 percent).
Peru was the best performing Latin market during the period, decreasing 9.9
percent. Rounding out the region, Argentina declined 16.4 percent, Colombia
declined 30.0, and Chile decreased 21.2 percent. Declining commodity prices
(particularly oil and copper) and political noise surrounding upcoming
presidential elections in Brazil and Venezuela negatively affected these
markets.
 
Weak fiscal fundamentals, coupled with rising political uncertainty, led to a
sharp decline in Brazilian stocks after a brief rally early in the year. We
question the ability of the Brazilian government to strengthen its fiscal
position prior to this year's elections. Political jitters already were apparent
in early June as President Cardoso's opposition (left-wing party candidate Lula)
began to gain popularity. President Cardoso's drop in the polls largely
reflected social malaise in the aftermath of the government's mishandling of the
drought and famine conditions in the Northeast, fires in the Amazon forest,
growing unemployment, and unfortunate statements regarding the work ethics of
those who are eligible to retire. While Brazil offers attractive value and
growth opportunities on a stock level, we are cautious with respect to its
widening fiscal deficit and vulnerable currency. We continue to focus on the
telecom sector given its strong operating earnings growth and privatization
potential.
 
The Mexican equities market faltered due to declining oil prices and a reduction
in capital inflows. During the past 12 months, the average oil export price for
Mexico has declined nearly 40 percent. Because oil represents 32 percent of
Mexico's total revenues, the sharp decline in energy prices has been
particularly detrimental for fiscal performance. Because of attractive
valuations introduced during the quarter in selected stocks, we increased our
exposure from a market-neutral position to a modest overweight position. In
spite of the oil-price squeeze, we expect economic growth in Mexico to remain
healthy, fueled by strong consumer demand. Thus, our focus is on such
consumer-related industries as beverages and retailers.
 
Stock prices in Argentina decreased in sympathy with the region and because of
concerns about a widening trade deficit. We increased our Argentine exposure to
a modest underweight position. We are encouraged by Argentina's strong economic
activity, low inflation, increasing international reserves, and improving fiscal
deficit. In Argentina, we are focusing on the telecom companies, which offer
strong operating earnings growth.
 
High domestic interest rates, commodity price deflation, and weak demand from
Asia for copper, forestry products, and fishmeal drove the Chilean market's
decline. Interest rates have been continually raised by the central bank since
the beginning of 1998 in an effort to defend the Chilean

peso and narrow the country's trade deficit. The high interest rates have
hindered stock market returns, as local investors preferred to tap the
fixed-income market and foreign investors remained on the sidelines awaiting
signs of a rate cut.
 
In other Latin American markets, investors greeted Colombia President-elect
Pastrana's victory on June 21 with optimism. However, lending rates averaging 15
percent--the highest levels in 13 years--dampened investor sentiment. In April,
we exited both the Peruvian and Venezuelan markets. In Peru, deteriorating
external accounts and slow growth have undermined equity-market performance.
Meanwhile, higher interest rates, a tense political environment, and currency
concerns led to our decision to eliminate our exposure to the Venezuelan market.
 
From a longer-term perspective, we are optimistic that capital flows will return
to Latin America. Stock prices in the region generally offer the best
fundamentals of all the emerging markets. As of the end of the reporting period,
the average Latin America stock sold for 10 times estimated 1999 earnings, while
profits were forecasted to grow by 15 percent next year.

The investment objective of the Morgan Stanley Money Market Fund is to provide a
high level of current interest income consistent with maintaining liquidity and
stability of principal. Obligations held by the Money Market Fund will have
remaining maturities of 397 days or less. In pursuing its investment objective,
the Fund invests in a broad range of U.S. dollar-denominated instruments, such
as government, bank, and commercial obligations.
 
The annualized seven-day yield and seven-day effective yield (which assumes all
dividends are reinvested) for the Money Market Fund as of June 30, 1998, were
4.67 percent and 4.77 percent, respectively. As with all money market
portfolios, the seven-day yields are not necessarily indicative of future
performance.
 
The U.S. economy began 1998 with a robust first quarter, as indicated by a GDP
of 5.4 percent. This level represented a healthy pace of economic growth.
Inflation at the CPI level was nonexistent, as commodity and producer prices
fell during the quarter. Interest rates declined, and consumers enjoyed
attractive financing which stimulated a strong housing market. Jobs remained
plentiful and the unemployment rate held steady at 4.7 percent.
 
As we moved into the second quarter, economic strength continued, although at a
more moderate pace. The labor market made further gains and the unemployment
rate fell to 4.5 percent. Wages rose in the second quarter, although not enough
to trigger market fears of higher inflation and tighter corporate profit
margins. Wage growth continues to be one of the key elements in defining the
expansion's life cycle. As long as wages grow at a gradual pace, the current
balance between low inflation and healthy corporate profits can remain intact.
 
By the end of the second quarter, interest rates had fallen to their lowest
levels of the year. The U.S. Treasury curve was flat to inverted, and the yield
on the long bond had fallen to 5.626 percent. Low domestic inflation played a
large part in driving interest rates lower, as did the Asian economic and fiscal
crisis. Pressures in Asia helped increase foreign demand for U.S. bonds, as
investors sought out higher-quality markets in which to invest and protect their
capital.
 
In situations where the economy is as strong as it is in the United States, the
markets typically become concerned that monetary policy might turn more
restrictive to slow economic growth and prevent inflation. Although these
concerns exist, the markets are less concerned that the Federal Reserve Board
might raise interest rates to slow economic growth because other regulating
factors exist. While the Asian crisis has helped to drive bond prices higher, it
has also widened the trade deficit and may provide a slowing effect on our
domestic economy. The strength in the dollar will have a similar effect as
foreign demand for U.S. exports will decline, slowing U.S. output. There is
concern that U.S. businesses have built up excessive inventories, which may put
corporate profit margins under pressure. If consumer demand is not sufficient to
relieve businesses of their surplus inventories, excessive carrying costs of
unsold goods can potentially tie up capital and stall corporate growth plans.

                              INVESTMENT OVERVIEW   (CONT.)
 
Most economists have lowered their third and fourth quarter GDP estimates by 1
to 2 percent in anticipation of the above economic effects. If these economists
are correct, and the economy slows automatically, the Fed may leave monetary
policy unchanged throughout the remainder of 1998. This outcome is especially
likely if Fed Chairman Alan Greenspan persists in exercising his influence over
the other members of the FOMC.
 
During the first half of the year, we invested the Fund's assets in fixed agency
and corporate obligations, as well as in floating rate instruments. The Fund
ended the second quarter with a weighted average maturity of 55 days. Our target
maturity range has been, and will continue to be between 50 and 60 days,
reflecting our neutral interest-rate outlook.
 
Current money market yields are very low and the yield curve offers little
protection against a potential interest rate hike by the Fed. While the market
is not expecting a Fed tightening, there is still little reason to extend our
overall maturity in the Fund. Yields in longer-dated maturities offer almost the
same return as do yields on shorter-dated maturities. We have been looking to
add more floating rate securities to the Fund to add incremental yield, without
taking undue interest rate risk. By buying floaters, we are protected against
any increase in interest rates by the Fed should they tighten early next year.
 
We believe that while it is likely that there will be no tightening throughout
the remainder of 1998, the risks of higher interest rates remain and could be
realized as early as the first quarter of 1999. Additionally, we may experience
a steepening in the yield curve before the end of this year as markets
anticipate future monetary policy changes. Should the curve experience some
steepening, we would view the event as an opportunity to extend the Fund's
average maturity.

PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE PERFORMANCE.
 
The investment objective of the Van Kampen U.S. Real Estate Fund, formerly the
Morgan Stanley U.S. Real Estate Fund, is to provide above-average current income
and long-term capital appreciation by investing primarily in equity securities
of companies in the U.S. real estate industry, including real estate investment
trusts.
 
For the year ended June 30, 1998, the Fund had a total return of 8.27 percent
for the Class A shares at net asset value (NAV), as compared to 8.05 percent for
the National Association of Real Estate Investment Trusts (NAREIT) Equity Index.
 
Following a difficult first quarter, the second quarter provided very little
improvement for REIT investors. The NAREIT Equity Index declined 4.59 percent
for the quarter, and was down 5.03 percent at the end of the reporting period.
This represents the first time that the REIT market provided a negative total
return on a quarterly basis since the first quarter of 1995. As is the pattern
in the REIT market, the second half of the year provides the majority of the
performance; this was true in the second half of 1997, with third and fourth
quarter returns of 11.8 percent and 1.8 percent, respectively.
 
In the first quarter, the key reason for the difficulties in REIT prices
appeared to be technical--the continued strength in the U.S. equity market led
many non-dedicated real estate investors to move funds to the broad market from
the REIT sector. In the second quarter, however, the continuation of price
weakness led to a greater focus on real estate fundamentals. As the U.S. real
estate cycle continues to age, the level of new construction has begun to raise
concerns among real estate

industry participants. Specifically, markets are being gauged for a view as to
when supply will surpass demand. Since the public market tends to look to the
future, we can expect multiples to contract in anticipation of a deterioration
in fundamentals.
 
After three years of strong performance, the sector is faced with competing
rallying cries of both REIT bulls and bears. One group of analysts finds value
in the sector by demonstrating the large disparity between the relative average
multiple of the S&P 500 versus REITs. These analysts cite REITs for providing
defensive characteristics and portfolio diversification. The bears point to the
cyclical nature of the real estate asset class and argue that multiples have
begun to contract in anticipation of a slowdown in the rate of return in U.S.
commercial real estate and an eventual downturn in capital values. Other
favorite criticisms advanced by the bears include the notion that the REIT
sector's reliance on raising equity capital to grow creates a supply-demand
imbalance for REIT shares, thus keeping a ceiling on share prices. This opinion
reflects the idea that non-dedicated investors will continue to avoid the
sector; in addition, it is not clear how much demand will be provided by
value-oriented investors or those investors searching for defensive vehicles.
 
As we have discussed, the multifamily and industrial markets have already
achieved equilibrium, with limited pockets of current supply problems. Despite a
rapidly accelerating pace of new office development, the potential for
widespread occupancy pressures from this sector does not appear on the horizon
until 1999 or 2000. New development is confined primarily to sunbelt suburban
locations and is only lightly scattered in a number of central business
districts. In the hotel sector, although recent concerns were focused on the
limited service segment of the market, the cautionary yellow flag is now being
waved for each of the categories. The reason that potential oversupply in the
hotel sector creates greater concern than in other sectors is that the typical
lease in a hotel is only one night, creating the potential for a rapid
deterioration of the operating environment. In light of the strong economy,
retail sales have been buoyant, leading to strong results for retailers and
greater demand to open new stores. We expect new development to meet this
demand.
 
It is not surprising that the equity offering calendar has become very light,
and that the few deals that were completed in the quarter were priced at far
lower levels than were desired by issuers. This is in contrast to 1997, which
featured a record level of new equity issuance. Given current valuations, we
expect that a number of the IPOs that have been filed will be postponed until
the market recovers. In addition, a number of companies that made large
acquisitions and that expected to complete equity follow-on offerings need to
carefully study alternative options. Clearly, if current pricing levels persist,
the rapid pace of equity securitization will slow as companies become reluctant
or unable to raise equity capital to finance their growth. This should apply to
acquisitions financed by cash as well as to the trend of trading property for
shares with institutional investors and private companies. Finally, we expect
that the merger environment may heat up, given that some companies are trading
at or below valuation levels that approximate their private real estate value.
 
The current market also may require a change of focus by the majority of the
REIT analyst community. The recent focus has been on setting targets for a
company's annual acquisitions pace and utilizing these targets to establish
estimates of funds from operations (FFO) per share. Since this analysis is
highly dependent on projecting future equity issuance and the corresponding
price for that issuance, current FFO estimates have become suspect. Our style of
focusing on NAV per share does not face this issue. However, to the extent that
we have attributed some portion of the NAV to "development value," we must
analyze the feasibility of a REIT completing its identified projects. We have
spent considerable time discussing the attitude of management toward enhancing
shareholder value by focusing on internal growth, development and redevelopment
of assets, stock buybacks, and the sale of non-strategic assets.
 
The REIT market has come under pressure by selling from non-dedicated investors.
These investors were heavily concentrated in larger-capitalization companies,
particularly those focusing in the office and hotel sectors (which were the two
best-performing sectors over the last three years). We have continued to shape
the portfolio with companies that we feel offer attractive fundamental

valuations relative to their underlying real estate value. As a result, we added
a number of large-cap companies that have faced the greatest price compression.
From a top-down perspective, we significantly added to the office sector as a
result of price declines. Previously, we attempted to overweight the office
sector due to favorable fundamentals, but lofty prices caused us to temper that
overweighting. High prices in the office sector were the result of external
growth expectations, which are in the process of being downgraded. Despite price
pressure in the hotel sector, we modestly decreased our exposure due to the
concerns discussed above. In order to pay for additions to the office sector, we
decreased our exposure to both multifamily and health care. These two sectors
were modestly valued and did not suffer the same declines in share price.
 
IMPORTANT FUND UPDATE
 
On October 23, 1997, the Trustees of the Fund approved its reorganization into
the Van Kampen Real Estate Securities Fund. Upon shareholder approval, the
reorganization of the Fund is expected to take place prior to December 31, 1998.
More information about the reorganization will be forwarded to you in a proxy
statement in the near future.
 
Your Fund and the Van Kampen Real Estate Securities Fund have substantially
similar investment objectives, policies and practices, and are managed by the
same portfolio management team. The Van Kampen Fund's investment objective is to
provide shareholders with long-term growth of capital, with current income as a
secondary objective.

dividends and distributions were reinvested.
PAST PERFORMANCE IS NOT PREDICTIVE OF FUTURE PERFORMANCE.
 
The Van Kampen Value Fund, formerly the Morgan Stanley Value Fund, seeks to
achieve above-average total return over a market cycle of three to five years,
consistent with reasonable risk. The Fund invests in a diversified portfolio of
common stocks and other equity securities that are believed to be undervalued on
the basis of key valuation parameters, including price-to-earnings, price-to-
sales, and price-to-cash flow ratios. In general, the Fund benefits from
investing in the stocks of companies with relative valuations below that which
is merited based upon the company's relative growth and profit characteristics.
 
The period beginning at the Fund's inception on July 7, 1997 ending June 30,
1998 can be characterized as a difficult period for low price-to-earnings value
investing--an approach the Fund embraces. As a result, the Fund fell
significantly short of its performance goal relative to the Standard & Poor's
500-Stock Index. The S&P 500 Index, which was driven by mega-cap, high price-
to-earnings stocks, returned 20.58 percent during this period, while the Fund's
return was only 4.81 percent for Class A shares at net asset value.
 
The performance shortfall that began in September of last year continued in the
first six months of 1998. The threat of a global economic slowdown stemming from
the economic crisis in Asia generated a strong interest in the shares of stable
growth companies. Because the Fund owns only low price-to-earnings stocks, many
of the traditionally stable sectors of the market--such as health care,
beverages, personal care products, and telephone and consumer services--are not
represented among this group. The market's preference for steady growth,
seemingly without regard for valuation, negatively affected the Fund's relative
performance.

- --------------------------------------------------------------------------------
 
                              INVESTMENT OVERVIEW   (CONT.)
 
From an industry perspective, the Fund's relative return was negatively affected
by an overweight position in the heavy industry/transport sector, as well as an
underweighting in defensive sectors such as telephone services, consumer
services, and health care. Adverse sector exposure accounted for roughly 1.2
percentage points of the differential between Fund performance and the Index.
 
The Fund applies strict value-based criteria for buying and selling stocks. New
names are added to the portfolio only if (1) the current price-to-earnings ratio
is in the bottom 40 percent of the market, (2) the earnings-per-share outlook is
flat to rising, and (3) the share price has underperformed by at least 20
percent on either an absolute or relative basis during the prior 12 to 18
months. Shares are sold if price-to-earnings multiples appreciate two quintiles
(a 40 percent increase) from the time of purchase. This strategy, which has been
effective in past market cycles, tends to underperform in periods of excessive
speculation or "nifty fifty" style growth domination, such as we had during the
reporting period.
 
During the past year, the inability of the Fund to own many mega-cap growth
stocks (due to valuation and process restrictions) generally is classified as
poor stock selection in our attribution analysis. Value names in each sector
simply did not keep pace with their growth counterparts. As such, negative stock
selection was responsible for roughly three-quarters of the Fund's
underperformance during the reporting period. Specifically, stock selection in
the food and tobacco, health care, technology, retail, and heavy
industry/transportation sectors penalized results by almost 14 percentage
points. Gains from our top performers, including Ford Motor Company, Compaq
Computer, AMR Corp., Delta Air Lines, Nellcor Puritan Bennett, Bergen Brunswig,
and Chase Manhattan, were offset by the negative impact of positions in Case
Corporation, Toys 'R' Us, Cummins Engine, Goodyear, Stratus Computer,
Harnischfeger, and Olsten.
 
Since inception, our value-driven selection process has guided us toward
economically sensitive stocks, as many of these companies continued to post
favorable relative profit margins and income gains. At the same time, valuations
moved below levels posted during the last recession of 1990-91.
 
The Fund's investable universe includes about 40 percent financial service
stocks. As a group, these names outperformed the S&P 500 during the last 12
months. Although we carried a modest overweight in this sector, the Fund avoided
the extreme overweight held by many value managers. Risk control factors prevent
us from holding 40 percent positions in any sector of the portfolio, including
financials. As a result, most of the Fund's holdings are low price-to-earnings,
nonfinancial companies; therefore, much of our relative performance shortfall
(versus peer group) resulted from our commitment to diversified low
price-to-earnings investing.
 
Recently, our stock-selection discipline has enabled us to diversify into more
defensive areas of the market. The Fund added new positions in EDS, a large-cap
technology service company; Bell Atlantic; Tenet Healthcare, a large for-profit
hospital chain; and Air Products & Chemicals, an industrial gas company. We also
expanded our bank holdings with new positions in BancOne, Washington Mutual, and
PNC Corp. Meanwhile, we trimmed the Fund's positions among consumer cyclicals,
including Ford Motor Company and AMR Corp., which experienced big upward moves.
 
At the end of the reporting period, we retained large underweightings in
consumer staples, consumer services, health care, technology, and telephone
utilities. These groups include many of the mega-cap growth names that led the
market in recent months. Of the 50 largest companies in the S&P 500 as of June
30, 1998, 41 were excluded from ownership due to the Fund's valuation criteria.
Eight of the nine companies that met the Fund's criteria are in the portfolio,
five of which are top-ten holdings. It should be noted, however, that the
subsequent gains in even those stocks have taken valuations beyond the Fund's
parameters for initial purchase.
 
The current characteristics of the Fund's holdings reflect our ongoing
commitment to value investing. The price-to-earnings ratio for the portfolio is
12.8 times earnings for the next 12 months, compared to 21.3 times earnings for
the S&P 500. The portfolio's price-to-sales ratio of 0.73 and price-to-cash flow
ratio of 10.1 compare favorably to the 1.8 times sales and 17.0 times cash flow
of the S&P 500. These price-to-earnings, price-to-sales, and price-to-cash flow
valuation discounts of

                              INVESTMENT OVERVIEW   (CONT.)
 
40 percent, 60 percent, and 41 percent, respectively, represent large valuation
discounts in the Fund's value strategy. These valuation discounts may be
warranted if the portfolio contained companies with poor or deteriorating
fundamentals; however, this simply is not the case.
 
The Fund's last 12-month growth rates of 5.5 percent for earnings-per-share, 8.1
percent for sales, and 7.0 percent for dividends approach the 7.4 percent, 11.2
percent, and 8.8 percent rates, respectively, of the S&P 500. Earnings estimate
revisions for the current and next fiscal years stand at -1.7 percent and -7.1
percent for the Fund versus -1.0 percent and -8.8 percent for the S&P 500.
Earnings estimate revisions are frequently a good predictor of future
performance. These comparisons underscore the Fund's investment premise, which
is based on the concept of valuation reconciliation. In today's narrow stock
market, valuation considerations have been eclipsed by the performance of a
relatively few large-cap growth stocks. Regardless of popular trends, however,
the Fund will adhere to its investment philosophy of buying good companies at
attractive prices. This approach has generated successful performance in the
past, and we have every confidence that it will do so in the future.

In accordance with SEC regulations, Fund performance since inception as shown at
left assumes that: the maximum sales charge was deducted from the initial
investment of $10,000 in Class A shares; all recurring fees (including
management fees) were deducted; and all dividends and distributions were
reinvested. The graph presents the performance of Class A and Class C shares
which have been in existence since the Fund's inception. The performance of
Class B shares will vary based upon the different inception date and the sales
charge and fees assessed to that Class.

The Van Kampen Worldwide High Income Fund, formerly known as the Morgan Stanley
Worldwide High Income Fund, seeks to offer investors high current income
consistent with relative stability of principal and potential for capital
appreciation. To achieve this objective, the Fund will invest primarily in
high-yielding, high risk fixed-income securities of issuers located throughout
the world.
 
For the 12 months ended June 30, 1998, the Van Kampen Worldwide High Income Fund
generated a total return of 3.40 percent for the Class A shares at net asset
value, as compared to a total return of 6.97 percent for the Worldwide High
Income Blended Index. This benchmark is comprised of 50 percent CS First Boston
High Yield Index, 25 percent J.P. Morgan Latin Eurobond Index, and 25 percent
J.P. Morgan Emerging Markets Bond Index Plus. In addition, the Lehman Aggregate
Bond Index returned 10.54 percent for the same period.***
 
During the last six months of 1997, volatility in the emerging debt markets
increased dramatically. Following a robust third quarter, the almost two-year
rally in emerging country debt came to an abrupt halt during the final three
months of 1997. After emerging market debt had reached an all-time high in terms
of price in early September, investors suddenly lost their appetite for risk,
causing prices to fall to a 12-month low by mid-October. Because of the
deepening Asian economic crisis, investors reassessed the risk premium
appropriate for investing in emerging markets. By late October, fears of
contagion from the Asian economic crisis overtook the market, sending prices of
***  The Lehman Aggregate Bond Index was initially selected as a benchmark for
     the Fund's performance; however, based upon the Fund's asset composition,
     we believe the Worldwide High Income Blended Index provides a more accurate
     benchmark for the Fund. Therefore, the Lehman Brothers Aggregate Bond Index
     will not be shown beginning with the December 31, 1998 semi-annual report.

emerging debt lower and spreads correspondingly wider. Although the majority of
outstanding emerging market debt is from Latin American and Eastern European
countries, all prices fell, as any asset with the word "emerging" in its
description was penalized.
 
The U.S. high-yield market performed reasonably well during the first half of
1998. The environment was particularly good in the first months of the year,
with 10-year Treasury yields declining about 30 basis points (0.3 percent) from
the beginning of the year to the end of June. Within the declining-rate
environment and solid economy, single B-rated bonds outperformed higher-quality
bonds in the high-yield market. Longer duration bonds also outperformed. The
lower tier and distressed sector continued to have problems, as it has for some
time. Strong performing industries included retail, technology, and utilities,
while weak performing ones included auto parts, energy, and textiles.
 
The Asian region remained in the spotlight throughout the first half of 1998 and
continued to dictate the tone of the market. In the first quarter, emerging
market debt recovered a large portion of the losses realized in October 1997, as
Asia appeared to stabilize. The market, however, remained volatile during this
period of spread compression, with general market spreads oscillating within a
100 basis point (1 percent) range. The past three months have seen the return of
the nervousness, volatility, and investor skepticism that we experienced during
the large emerging markets sell-offs in 1994 and the fourth quarter of 1997. The
reasons for this current round of volatility are less obvious than past
episodes, as we have not seen the classic signs of a decrease in global
liquidity. In addition, this sell-off has not been precipitated by political or
social instability in any major country. Globally, interest rates continue to
remain low, there have not been large flows out of emerging market debt mutual
funds, global inflation remains quite well contained, and most emerging
countries continue to pursue virtuous economic policies. The poor health of the
Japanese economy and of major Japanese banks, however, has caused investors to
adjust risk premiums higher and has caused liquidity for most emerging countries
to evaporate. Investors fear that Japan's inability to stabilize its economy
will continue to weaken the yen, and might eventually cause a devaluation in
China. This would increase the risk of another round of currency devaluation in
Asia and might further depress commodity prices, a large source of earnings for
many emerging countries. The good news is that markets have considerably
discounted this negative scenario. While Asia continues to cast a dark shadow
over the emerging markets, any evidence of improving or stable conditions in
Asia should allow prices on emerging market debt to recover substantially.
 
As markets rallied in the beginning of 1998, we decreased the Fund's exposure to
the market in general, particularly Russia. We remained cautious during most of
the first quarter and only increased our exposure to emerging market debt after
the market had sold off significantly. As we began to feel that valuations more
accurately represented the risks in the market, we established an overweight
position in Russia and Mexico. The overweight in Russia has hurt the Fund's
performance as Russian debt performed below other emerging market bonds by a
wide margin in June, with the Russian subcomponent of the J.P. Morgan Emerging
Markets Bond Index returning -13.85 percent for the month. The dramatic sell-off
in Russian assets reflects investors' concerns about short-term liquidity rather
than longer-term solvency issues. Russia relies heavily on foreign debt and
foreign investors in its local markets to fund its budget deficit, which has
been aggravated this year by poor tax collection resulting from low oil prices.
As global liquidity has become scarce, Russia has come under scrutiny as it
relies on the markets for constant funding. We believe that the new
administration in Moscow has developed a credible program to avoid full-blown
economic crisis, and Russia will survive its current predicament. The Russians
are working closely with the IMF and should, in the next two months, come to
terms for additional aid and an expanded program to bolster international
reserves. We will continue to overweight in Mexico, as we remain confident about
the soundness of Mexico's macroeconomics fundamentals. The Mexican economy
should register growth of 5 percent this year; unlike 1995, this growth is more
balanced now as it is being driven by both the export and nontradable sectors.

which offers redeemable shares of diversified and non-diversified investment
portfolios.
 
As of June 30, 1998, the Fund had sixteen separate active investment portfolios:
Van Kampen Aggressive Equity Fund (formerly Morgan Stanley Aggressive Equity
Fund), Van Kampen American Value Fund (formerly Morgan Stanley American Value
Fund), Van Kampen Asian Growth Fund (formerly Morgan Stanley Asian Growth Fund),
Van Kampen Emerging Markets Fund (formerly Morgan Stanley Emerging Markets
Fund), Van Kampen Equity Growth Fund, Van Kampen Global Equity Fund (formerly
Morgan Stanley Global Equity Fund), Van Kampen Global Equity Allocation Fund
(formerly Morgan Stanley Global Equity Allocation Fund), Van Kampen Global Fixed
Income Fund (formerly Morgan Stanley Global Fixed Income Fund), Morgan Stanley
Government Obligations Money Market Fund, Van Kampen High Yield & Total Return
Fund (formerly Morgan Stanley High Yield Fund), Van Kampen International Magnum
Fund (formerly Morgan Stanley International Magnum Fund), Van Kampen Latin
American Fund (formerly Morgan Stanley Latin American Fund), Morgan Stanley
Money Market Fund, Van Kampen U.S. Real Estate Fund (formerly Morgan Stanley
U.S. Real Estate Fund), Van Kampen Value Fund (formerly Morgan Stanley Value
Fund), and Van Kampen Worldwide High Income Fund (formerly Morgan Stanley
Worldwide High Income Fund) (referred to herein respectively as "Aggressive
Equity Fund," "American Value Fund," "Asian Growth Fund," "Emerging Markets
Fund," "Equity Growth Fund," "Global Equity Fund", "Global Equity Allocation
Fund," "Global Fixed Income Fund," "Government Obligations Money Market Fund"
"High Yield & Total Return Fund," "International Magnum Fund," "Latin American
Fund," "Money Market Fund," "U.S. Real Estate Fund," "Value Fund," "Worldwide
High Income Fund," and individually a "Portfolio" and collectively as the
"Portfolios"). The financial statements of the Equity Growth Fund are presented
separately.
 
The Fund currently offers three classes of shares, Class A, Class B, and Class C
Shares (with the exception of the Government Obligations Money Market and Money
Market Funds). Class A shares are sold with a front-end sales charge of up to
5.75% (4.75% for shares sold in the Global Fixed Income Fund, High Yield & Total
Return Fund and the Worldwide High Income Fund). For certain purchases of Class
A shares, the front-end sales charge may be waived and a contingent deferred
sales charge of 1.00% imposed in the event of certain redemptions within one
year of the purchase. Class B shares are sold with a contingent deferred sales
charge on redemptions made within 5 years of purchase which declines annually
from 5% for redemptions made in year one, down to 1.50% in year five. The
contingent deferred sales charge is based on the lesser of the current market
value of the shares redeemed or the total cost of such shares. Class B shares
will automatically convert to Class A shares after the eighth year following
purchase. Class C shares are sold with a contingent deferred sales charge of 1%
for shares that are redeemed within one year of purchase, based on the lesser of
the current market value of the shares redeemed or the total cost of such
shares. All three classes of shares have identical voting, dividend, liquidation
and other rights. The Fund began offering the current Class B shares on August
1, 1995. Class B shares held prior to May 1, 1995 were renamed Class C shares.
 
The Global Equity Fund, and Value Fund commenced operations on October 29, 1997
and July 7, 1997 respectively.
 
A. ACCOUNTING POLICIES: The following significant accounting policies are in
conformity with generally accepted accounting principles for investment
companies. Such policies are consistently followed by the Fund in the
preparation of the financial statements. Generally accepted accounting
principles require management to make estimates and assumptions that affect the
reported amounts and disclosures in the financial statements. Actual results may
differ from those estimates.
 
1. SECURITY VALUATION: Equity securities listed on a U.S. exchange and equity
securities traded on NASDAQ are valued at the latest quoted sales price on the
valuation date. Securities listed on a foreign exchange are valued at their
closing price. Unlisted securities and listed securities not traded on the
valuation date for which market quotations are readily available are valued at
the average of the current bid and asked prices obtained from reputable brokers.
Bonds and other fixed income securities may be valued according to the broadest
and most representative market. In addition, bonds and other fixed income
securities may be valued on the basis of prices provided by a pricing service
which take into account institutional size trading in similar groups of
securities. Debt securities purchased with remaining maturities of 60 days or
less are valued at amortized cost, if it approximates market value. Securities
owned by the Government Obligations Money Market and Money Market Funds are
stated at amortized cost, which approximates market value. All other securities
and assets for which market values are not readily available are valued at fair
value as determined in good faith by the Board of Directors, although the actual
calculations may be done by others.
 
At June 30, 1998, approximately 93% and 91% of the net assets of the High Yield
& Total Return Fund and the Worldwide High Income Fund, respectively, consisted
of high yield securities rated below investment grade. Investments in high yield
securities are accompanied by a greater degree of credit risk and the risk tends
to be more

sensitive to economic conditions than higher rated securities. Certain
securities may be valued on the basis of bid prices provided by one principal
market maker.
 
2. TAXES: It is each portfolio's intention to qualify as a regulated investment
company and distribute all of its taxable income. Accordingly, no provision for
Federal income taxes is required in the financial statements. A portfolio may be
subject to taxes imposed by countries in which it invests. Such taxes are
generally based on income earned or gains realized or repatriated. Taxes are
accrued and applied to net investment income, net realized capital gains and net
unrealized appreciation, as applicable, as the income is earned or capital gains
are recorded.
 
At June 30, 1998, the following Portfolios had available capital loss
carryforwards to offset future net capital gains, to the extent provided by U.S.
Federal income tax regulations, through the indicated expiration dates:

To the extent that capital loss carryforwards are used to offset any future net
capital gains realized during the carryforward period as provided by U.S.
Federal income tax regulations, no capital gains tax liability will be incurred
by a Portfolio for gains realized and not distributed. To the extent that
capital gains are so offset, such gains will not be distributed to shareholders.
 
Net capital and net currency losses incurred after October 31 and within the
taxable year are deemed to arise on the first business day of the Portfolio's
next taxable year. For the period from November 1, 1997 to June 30, 1998 certain
Portfolios incurred and elected to defer until July 1, 1998, for U.S. Federal
income tax purposes, net currency and capital losses of approximately:

3. REPURCHASE AGREEMENTS: In connection with transactions in repurchase
agreements, a bank as custodian for the Fund takes possession of the underlying
securities, with a market value at least equal to the amount of the repurchase
transaction, including principal and accrued interest. To the extent that any
repurchase transaction exceeds one business day, the value of the collateral is
marked-to-market on a daily basis to determine the adequacy of the collateral.
In the event of default on the obligation to repurchase, the Fund has the right
to liquidate the collateral and apply the proceeds in satisfaction of the
obligation. In the event of default or bankruptcy by the counterparty to the
agreement, realization and/or retention of the collateral or proceeds may be
subject to legal proceedings.
 
4. FOREIGN CURRENCY TRANSLATION AND FOREIGN INVESTMENTS: The books and records
of the Fund are maintained in U.S. dollars. Foreign currency amounts are
translated into U.S. dollars at the mean of the bid and asked prices of such
currencies against U.S. dollars last quoted by a major bank as follows:
 
    - investments, other assets and liabilities at the prevailing rates of
      exchange on the valuation date;
 
    - investment transactions and investment income at the prevailing rates of
      exchange on the dates of such transactions.
 
Although the net assets of the Fund are presented at the foreign exchange rates
and market values at the close of the period, the Fund does not isolate that
portion of the results of operations arising as a result of changes in the
foreign exchange rates from the fluctuations arising from changes in the market
prices of the securities held at period end. Similarly, the Fund does not
isolate the effect of changes in foreign exchange rates from the fluctuations
arising from changes in the market prices of securities sold during the period.
Accordingly, realized and unrealized foreign currency gains (losses) on
investments are included in the reported net realized and unrealized gains
(losses) on investments. However, pursuant to U.S. Federal income tax
regulations, the foreign currency portion of gains and losses realized on sales
and maturities of foreign denominated debt securities is treated as ordinary
income for U.S. Federal income tax purposes.
 
Net realized gains (losses) on foreign currency transactions represent net
foreign exchange gains (losses) from forward foreign currency exchange
contracts, disposition of foreign currencies, currency gains or losses realized
between the trade and settlement dates on securities transactions, and the
difference between the amount of investment income and foreign withholding taxes
recorded on the Fund's books and the U.S. dollar equivalent amounts actually
received or paid. Net unrealized currency gains (losses) from valuing foreign
currency denominated assets and liabilities at period end exchange rates are
reflected as a component of unrealized appreciation (depreciation) on
investments and foreign currency translations in the Statement of Assets and
Liabilities. The change in net unrealized currency gains (losses) for the period
is reflected on the Statement of Operations.
 
The net assets of certain Portfolios include issuers located in emerging
markets. There will be certain considerations and risks of these investments not
typically associated with investments in the United States. Changes in currency
 
                                                              ------------------
                                                                    131

exchange rates will affect the value of and investment income from such
securities. The smaller size of the markets themselves, lesser liquidity and
greater volatility contribute to risks in valuation as compared with the U.S.
securities markets. Also there is often substantially less publicly available
information about these issuers. Emerging markets may be subject to a greater
degree of governmental involvement in the economy and greater economic and
political uncertainty. Accordingly the price which the Fund realizes upon the
sale of securities in such markets may not be equal to its value as presented in
the financial statements.
 
Prior governmental approval for foreign investments may be required under
certain circumstances in some countries, and the extent of foreign investment in
domestic companies may be subject to limitations in other countries. Foreign
ownership limitations also may be imposed by the charters of individual
companies to prevent, among other concerns, violation of foreign investment
limitations. As a result, an additional class of shares (identified as "Foreign"
in the Portfolio of Investments) may be created and offered for investment. The
"local" and "foreign" shares' market values may vary.
 
5. FOREIGN CURRENCY EXCHANGE CONTRACTS: Certain Portfolios may enter into
foreign currency exchange contracts to attempt to protect securities and related
receivables and payables against changes in future foreign currency exchange
rates. A currency exchange contract is an agreement between two parties to buy
or sell currency at a set price on a future date. The market value of the
contract will fluctuate with changes in currency exchange rates. The contract is
marked-to-market daily and the change in market value is recorded by the
Portfolio as unrealized gain or loss on foreign currency translation. The
Portfolio records realized gains or losses on foreign translation when the
contract is closed, equal to the difference between the value of the contract at
the time it was opened and the value of the contract at the time it was closed.
Risks may arise upon entering into these contracts from the potential inability
of counterparties to meet the terms of their contracts but is generally limited
to the amount of unrealized gain on the contracts, if any, at the date of
default. Risks may also arise from the unanticipated movements in the value of a
foreign currency relative to the U.S. dollar.
 
6. SHORT SALES: Certain Portfolios may sell securities short. A short sale is a
transaction in which the Portfolios sell securities it may or may not own, but
has borrowed, in anticipation of a decline in the market price of the
securities. The Portfolios are obligated to purchase securities at the market
price to replace the borrowed securities at the time of replacement. The
Portfolios may have to pay a premium to borrow the securities as well as pay
dividends or interests payable on the securities until they are replaced. The
Portfolios' obligation to replace the securities borrowed in connection with a
short sale will generally be secured by collateral deposited with the broker
that consists of cash, U.S. government securities or other liquid, high grade
debt obligations. In addition, the Portfolios will place in a segregated account
with its Custodian an amount of cash, U.S. government securities or other liquid
high grade debt obligations equal to the difference, if any, between (1) the
market value of the securities sold at the time they were sold short, and (2)
any cash, U.S. government securities, or other liquid high grade debt
obligations deposited as collateral with the broker in connection with the short
sale (not including the proceeds of the short sale). Short sales by the
Portfolios involve certain risks and special considerations. Possible losses
from short sales differ from losses that could be incurred from the purchase of
a security, because losses from short sales may be unlimited, whereas losses
from purchases cannot exceed the total amount invested.
 
7. PURCHASED OPTIONS: Certain Portfolios may purchase call or put options on
their portfolio securities. A Portfolio may purchase call options to protect
against an increase in the price of a security it anticipates purchasing. A
Portfolio may purchase put options on securities which it holds to protect
against a decline in the value of the security. Risks may arise from an
imperfect correlation between the change in market value of the securities held
by the Portfolio and the prices of options relating to the securities purchased
or sold by the Portfolio and from the possible lack of a liquid secondary market
for an option. The maximum exposure to loss for any purchased option is limited
to the premium initially paid for the option.
 
8. SECURITY LENDING: Certain Portfolios may lend investment securities to
qualified institutional investors who borrow securities in order to complete
certain transactions. By lending its investment securities, a Portfolio attempts
to increase its net investment income through the receipt of interest on the
loan. Any gain or loss in the market price of the securities loaned that might
occur and any interest earned or dividends declared during the term of the loan
would accrue to the account of the Portfolio. Risks of delay in recovery of the
securities or even loss of rights in the collateral may occur should the
borrower of the securities fail financially. Risks may also arise to the extent
that the value of the collateral decreases below the value of the securities
loaned.
 
Portfolios that lend securities receive cash, securities issued or guaranteed by
the U.S. Government or letters of credit as collateral in an amount equal to or
exceeding 100% of the current market value of the loaned securities. Any cash
received as collateral is invested in interest bearing repurchase agreements
with approved counterparties. A portion of the interest received on the
repurchase agreements is retained by the Fund and the remainder is rebated to
the borrower of the securities. The net amount of interest earned and interest
rebated is included in the

At June 30, 1998, the Fund had invested the cash collateral in a repurchase
agreement with Goldman Sachs. Such repurchase agreement was collateralized by
U.S. Treasury obligations.
 
Morgan Stanley Trust Company, an affiliate of the Investment Sub-Adviser,
administers the security lending program and for its services the Fund incurred
fees in the amount of $29,000 for the year ended June 30, 1998.
 
9. FORWARD COMMITMENTS AND WHEN-ISSUED/DELAYED DELIVERY SECURITIES: Each
Portfolio may make forward commitments to purchase or sell securities. Payment
and delivery for securities which have been purchased or sold on a forward
commitment basis can take place a month or more (not exceeding 120 days) after
the date of the transaction. Additionally each Portfolio may purchase securities
on a when-issued or delayed delivery basis. Securities purchased on a
when-issued or delayed delivery basis are purchased for delivery beyond the
normal settlement date at a stated price and no income accrues to the Portfolio
on such securities prior to delivery. When the Portfolio enters into a purchase
transaction on a when-issued or delayed basis, it establishes a segregated
account in which it maintains liquid assets in an amount at least equal in value
to the Portfolio's commitments to purchase such securities. Purchasing
securities on a forward commitment or when-issued or delayed delivery basis may
involve a risk that the market price at the time of delivery may be lower than
the agreed upon purchase price, in which case there could be an unrealized loss
at the time of delivery.
 
10. STRUCTURED SECURITIES: The Worldwide High Income Fund may invest in
interests in entities organized and operated solely for the purpose of
restructuring the investment characteristics of sovereign debt obligations. This
type of restructuring involves the deposit with or purchase by an entity of
specified instruments and the issuance by that entity of one or more classes of
securities ("Structured Securities") backed by, or representing interests in,
the underlying instruments. Structured Securities generally will expose the
Portfolio to credit risks equivalent to that of the underlying instruments.
Structured Securities are typically sold in private placement transactions with
no active trading market. Investments in Structured Securities may be more
volatile than their underlying instruments, however, any loss is limited to the
amount of the original investment.
 
11. ORGANIZATIONAL COSTS: The organizational costs of the Portfolios are being
amortized on a straight line basis over a period of five years beginning with
each respective Portfolio's commencement of operations. Van Kampen Investments
Inc. has agreed that in the event any of its initial shares in a Portfolio which
comprised the Fund at its inception are redeemed, the proceeds on redemption
will be reduced by the pro-rata portion of any unamortized organizational costs
in the same proportion as the number of shares redeemed bears to the initial
shares held at the same time of redemption.
 
12. FUTURES CONTRACTS: Certain Portfolios may purchase and sell futures
contracts. Future contracts provide for the sale by one party and purchase by
another party of a specified amount of a specified security, instrument or
basket of instruments. Futures contracts (secured by cash and securities
deposited with brokers as "initial margin") are valued based upon their quoted
daily settlement prices; changes in initial settlement value (represented by
cash paid to or received from brokers as "variation margin") are accounted for
as unrealized appreciation (depreciation). When futures contracts are closed,
the difference between the opening value at the date of purchase and the value
at closing is recorded as realized gains or losses in the Statement of
Operations.
 
Certain Portfolios may use futures contracts in order to hedge against
unfavorable changes in the value of securities or to remain fully invested and
to reduce transaction costs. Futures contracts involve market risk in excess of
the amounts recognized in the Statement of Assets and Liabilities. Risks arise
from the possible movements in security values underlying these instruments
applied to the notional value of the contract. The change in value of futures
contracts primarily corresponds with the value of their underlying instruments,
which may not correlate with the change in value of the hedged investments. In
addition, there is the risk that a Portfolio may not be able to enter into a
closing transaction because of an illiquid secondary market.
 
13. SWAP AGREEMENTS: Certain Portfolios may enter into swap agreements to
exchange the return generated by one security, instrument or basket of
instruments for the return generated by another security, instrument or basket
of instruments. The following summarizes swaps which may be entered into by the
Portfolios:
 
Interest Rate Swaps:  Interest rate swaps involve the exchange of commitments to
pay and receive interest based on a notional principal amount. Net periodic
interest payments to be received or paid are accrued daily and are recorded in
the Statement of Operations as an adjustment to interest income. Interest rate
swaps are marked-to-market daily based upon quotations from market makers and
the change, if any, is recorded as unrealized appreciation or depreciation in
the Statement of Operations.
 
Total Return Swaps:  Total return swaps involve commitments to pay interest in
exchange for a market-linked
 
                                                              ------------------
                                                                    133

                                 JUNE 30, 1998
 
- --------------------------------------------------------------------------------
 
return based on a notional amount. To the extent the total return of the
security or index underlying the transaction exceeds or falls short of the
offsetting interest obligation, the Portfolio will receive a payment from or
make a payment to the counterparty, respectively. Total return swaps are
marked-to-market daily based upon quotations from market makers and the change,
if any, is recorded as unrealized gains or losses in the Statement of
Operations. Periodic payments received or made at the end of each measurement
period, but prior to termination, are recorded as realized gains or losses in
the Statement of Operations.
 
Realized gains or losses on maturity or termination of interest rate and total
return swaps are presented in the Statement of Operations. Because there is no
organized market for these swap agreements, the value reported in the Statement
of Net Assets may differ from that which would be realized in the event the
Portfolio terminated its position in the agreement. Risks may arise upon
entering into these agreements from the potential inability of the
counterparties to meet the terms of the agreements and are generally limited to
the amount of net interest payments to be received and/or favorable movements in
the value of the underlying security, if any, at the date of default. Swap
contracts involve market risks in excess of the amounts recognized in the
Statement of Assets and Liabilities.
 
14. OTHER: Security transactions are accounted for on the date the securities
are purchased or sold. Realized gains and losses on the sale of investment
securities are determined on the specific identified cost basis. Dividend income
is recorded on the ex-dividend date (except for certain foreign dividends which
may be recorded as soon as the Portfolio is informed of such dividends), net of
applicable withholding taxes where recovery of such taxes is not reasonably
assured. Interest income is recognized on the accrual basis except where
collection is in doubt. Discounts and premiums on securities purchased are
amortized according to the effective yield method over their respective lives.
Most expenses of the Fund can be directly attributed to a particular Portfolio.
Expenses which cannot be directly attributed are apportioned among the
Portfolios based upon relative net assets. Income, expenses (other than class
specific expenses) and realized and unrealized gains or losses are allocated to
each class of shares based upon their relative net assets. Distributions from
the Portfolios are recorded on the ex-distribution date.
 
Certain Portfolios own shares of real estate investment trusts ("REITs") which
report information on the source of their distributions annually. A portion of
distributions received from REITs during the year is estimated to be a return of
capital and is recorded as a reduction of the cost of those securities.
 
The amount and the character of income and capital gain distributions to be paid
by the Fund are determined in accordance with Federal income tax regulations
which may differ from generally accepted accounting principles. These
differences are primarily due to differing book and tax treatment for foreign
currency transactions, net operating losses, foreign taxes on net realized
gains, deductibility of interest expense on short sales and gains on certain
securities of corporations designated as "passive foreign investment companies."
 
Permanent book and tax basis differences relating to shareholder distributions
may result in reclassification among undistributed net investment income (loss),
accumulated net realized gain (loss) and paid in capital.
 
Permanent book and tax basis differences, if any, are not included in ending
undistributed (distributions in excess of) net investment income for the purpose
of presenting net investment income (loss) per share in the Financial
Highlights.
 
The reclassifications arising from current book/tax differences resulted in
increases (decreases) to the components of net assets as follows:

To the Board of Directors and Shareholders of
Van Kampen Series Fund Inc.
 
In our opinion, the accompanying statements of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of the Aggressive Equity Fund,
American Value Fund, Asian Growth Fund, Emerging Markets Fund, Global Equity
Fund, Global Equity Allocation Fund, Global Fixed Income Fund, Government
Obligations Money Market Fund, High Yield & Total Return Fund, International
Magnum Fund, Latin American Fund, Money Market Fund, U.S. Real Estate Fund,
Value Fund and the Worldwide High Income Fund (portfolios of the Van Kampen
Series Fund Inc. hereafter referred to as the "Fund") at June 30, 1998, the
results of each of their operations, the changes in each of their net assets and
the financial highlights for each of the periods presented, in conformity with
generally accepted accounting principles. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at June 30, 1998 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.
