 OVERVIEW

LETTER TO SHAREHOLDERS
October 20, 2000

Dear Shareholder,

The first three quarters of 2000 proved to be especially volatile, with all of
the major markets declining in the spring and spending the following months
trying to recover. To manage one's portfolio during such unpredictable times
requires investment-management experience, and the following pages should give
you some insight into how we have performed in this difficult environment.

In this report, the portfolio managers will explain how your investment
performed during the reporting period and describe the strategies they used to
manage your fund during that span. The report will also show you how your
investment has performed over time. Helpful charts summarize the fund's largest
investments, and you can examine the complete portfolio to see all of your
fund's holdings as of the end of your fund's reporting period.

                  At Van Kampen, we place a high priority on providing you and
                  your financial advisor with the information you need to help
                  you monitor your investments during all types of markets. With
                  nearly four generations of investment-management experience,
                  we've been around long enough to understand that by investing
with Van Kampen you're entrusting us with much more than your money. Your
investments may help make it possible to afford your next house, keep up with
rising college costs, or enjoy a comfortable retirement.

No matter what your reasons for investing, we're thankful that you've chosen to
place your investments with Van Kampen. We will continue to apply our
generations of money-management experience to helping you pursue life's true
wealth.

Sincerely,

[SIG]
Richard F. Powers, III
President and CEO
Van Kampen Investments

ECONOMIC SNAPSHOT

ECONOMIC GROWTH
ECONOMIC GROWTH WAS STRONG DURING THE REPORTING PERIOD, UNDERPINNED BY LOW
UNEMPLOYMENT AND RISING PRODUCTIVITY, YET THERE WERE SIGNS THAT A HEALTHY
SLOWDOWN WAS UNDERWAY. GROSS DOMESTIC PRODUCT, THE PRIMARY MEASURE OF ECONOMIC
GROWTH, INCREASED AT A 2.7 PERCENT ANNUALIZED RATE FOR THE THIRD QUARTER OF
2000. FOLLOWING MILD FIRST- AND SECOND-QUARTER DATA, THIS THIRD-QUARTER FIGURE
OFFERS FURTHER EVIDENCE THAT GROWTH MIGHT BE SETTLING BACK TO A MORE MODERATE
AND SUSTAINABLE PACE THAN ITS RAPID RATE IN LATE 1999.

CONSUMER SPENDING AND EMPLOYMENT
CONCERNS ABOUT INFLATION REMAINED AT BAY DUE IN PART TO A GRADUAL SLOWDOWN IN
CONSUMER SPENDING. RISING INTEREST RATES, HIGHER ENERGY COSTS, AND A
DISAPPOINTING STOCK MARKET BEGAN TO TEMPER RETAIL SALES, WHICH LEVELED OFF FROM
THE BLISTERING PACE OF LATE 1999 AND EARLY 2000. AND WHILE CONSUMER SPENDING WAS
BRISK, THE OVERALL TREND HAS BEEN DOWNWARD THIS YEAR.

THE JOBLESS RATE CONTINUED TO BE EXTREMELY LOW BY HISTORICAL STANDARDS, BUT
RECENT CUTS IN MANUFACTURING PAYROLLS SUPPORT THE POPULAR BELIEF THAT THE
ECONOMY IS MODERATING. ALTHOUGH EMPLOYER COSTS SUCH AS WAGES AND BENEFITS WERE
RISING AT THE END OF 1999 AND IN THE BEGINNING OF 2000, OVER THE PAST SIX MONTHS
THE EMPLOYMENT COST INDEX HAS SHOWN MARKED DECELERATION, WHICH SHOULD HELP EASE
INFLATION CONCERNS.

INTEREST RATES AND INFLATION
THE FEDERAL RESERVE BOARD (THE FED) RAISED INTEREST RATES FOUR TIMES DURING THE
LAST 12 MONTHS IN AN EFFORT TO WARD OFF INFLATION BY CURBING ECONOMIC GROWTH.
OVER THE SAME PERIOD, THE CONSUMER PRICE INDEX ROSE 3.5 PERCENT, WHICH INDICATED
THAT INFLATION GENERALLY REMAINS UNDER CONTROL.

THE FED HAS ACKNOWLEDGED THE RISK OF RISING INFLATION AND WILL STAY ON GUARD, AS
RISING ENERGY COSTS AND LOW UNEMPLOYMENT THREATEN TO PROPEL THIS FIGURE UPWARD
IN THE COMING MONTHS. AS LONG AS INFLATION IS CONTAINED AND THE PACE OF ECONOMIC
GROWTH REMAINS FAVORABLE, THE FED IS LIKELY TO HOLD INTEREST RATES STEADY IN THE
SHORT TERM, WHICH COULD HELP STABILIZE THE STOCK AND BOND MARKETS.

(1) Assumes reinvestment of all distributions for the period and does not
    include payment of the maximum sales charge (5.75% for Class A Shares) or
    contingent deferred sales charge ("CDSC"). On purchases of Class A Shares of
    $1 million or more, a CDSC of 1% may be imposed on certain redemptions made
    within one year of purchase. Returns for Class B Shares are calculated
    without the effect of the maximum 4% CDSC, charged on certain redemptions
    made within one year of purchase and declining to 0% after the sixth year.
    Returns for Class C Shares are calculated without the effect of the maximum
    1% CDSC, charged on certain redemptions made within one year of purchase. If
    the sales charges were included, total returns would be lower. These returns
    do include Rule 12b-1 fees of up to .25% for Class A Shares and 1% for Class
    B and Class C Shares.

(2) Standardized total return. Assumes reinvestment of all distributions for the
    period and includes payment of the maximum sales charge (5.75% for Class A
    Shares) or contingent deferred sales charge ("CDSC") for Class B and C
    Shares and Rule 12b-1 fee. On purchases of Class A Shares of $1 million or
    more, a CDSC of 1% may be imposed on certain redemptions made within one
    year of purchase. Returns for Class B Shares are calculated with the effect
    of the maximum 4% CDSC, charged on certain redemptions made within one year
    of purchase and declining to 0% after the sixth year. Returns for Class C
    Shares are calculated with the effect of the maximum 1% CDSC, charged on
    certain redemptions made within one year of purchase. The Rule 12b-1 fee for
    Class A Shares is up to .25% and for Class B and Class C Shares is 1%.

(3) The total return reflects the conversion of Class B Shares into Class A
    Shares six years after the end of the calendar month in which the shares
    were purchased. See footnote 3 in the Notes to Financial Statements for
    additional information.

    Because the Fund concentrates investments in the utility industry, it may be
    more susceptible to any economic, political or regulatory occurrence
    effecting this industry. Foreign securities involve the risk of fluctuations
    in foreign exchange rates, future political and economic developments.
    Lower-rated securities are referred to as "junk bonds" and are considered
    speculative with regards to payment of interest and principal.

    As a result of recent market activity, current performance may vary from the
    figures shown.

Q&A WITH YOUR PORTFOLIO MANAGERS

WE RECENTLY SPOKE WITH THE MANAGEMENT TEAM OF THE VAN KAMPEN UTILITY FUND ABOUT
THE KEY EVENTS AND ECONOMIC FORCES THAT SHAPED THE MARKETS AND INFLUENCED THE
FUND'S RETURN DURING THE SIX MONTHS ENDED SEPTEMBER 30, 2000. THE TEAM IS LED BY
CHRISTINE DRUSCH, SENIOR PORTFOLIO MANAGER, WHO HAS MANAGED THE FUND SINCE
AUGUST 1997 AND HAS WORKED IN THE INVESTMENT INDUSTRY SINCE 1985. SHE IS JOINED
BY PORTFOLIO MANAGERS DAVID MCLAUGHLIN AND SEAN CONNER. THE FOLLOWING DISCUSSION
REFLECTS THEIR VIEWS ON THE FUND'S PERFORMANCE.

Q   HOW WOULD YOU CHARACTERIZE
    THE MARKET DURING THE REPORTING PERIOD, AND TO WHAT DO YOU ATTRIBUTE THE
    FUND'S PERFORMANCE?

A   The stock market was volatile
across all industries. The Federal Reserve Board attempted to moderate economic
growth by hiking interest rates, which caused many investors to wonder whether
high-growth, high-valuation companies--many of which are in the technology and
telecommunications sectors--could sustain such lofty valuations. A sell-off
occurred in the spring as investors moved out of high-growth names and turned
their focus to "old economy" stocks, including utility securities. This rotation
to utilities helped the utility sector outperform the broad market for the
six-month period ended September 30, 2000.

    In this market environment, the fund returned 12.15 percent for the six
months ended September 30, 2000 (Class A shares at net asset value; if the
maximum sales charge of 5.75 percent were included, the return would have been
lower). Past performance is no guarantee of future results. As a result of
recent market activity, current performance may vary from the figure shown.
Please refer to the chart and footnotes on page 4 for additional fund
performance results. Although utility companies have typically been considered
"old economy," they have recently benefited from the demands of the "new
economy." For example, the explosion of computer, Internet, and wireless
telephone usage has created a need for uninterrupted service to home and
corporate users. This demand has fueled new growth in traditional utility
companies. Furthermore, the deregulation of the utilities industries is
generating increased competition, which is propelling companies to heighten
their investment in technology and service in order to maintain market share.

                                        7

    The fund underperformed its benchmark, the Standard & Poor's Utilities
Index, which returned 41.33 percent during the reporting period. This
underperformance was largely due to the fund's weighting in telecommunications
services, as defined by the fund's prospectus as part of the utilities industry.
Conversely, the benchmark index does not represent telecommunications services
and therefore was not impacted by its poor performance. However, the fund
outperformed its peer group, the Lipper Utility Fund Index, which returned 4.39
percent during the reporting period. The S&P Utilities Index is a broad-based,
unmanaged index that reflects the general performance of electric utility
stocks. The Lipper Utility Fund Index is a statistical composite of the 30
largest utility funds in the Lipper database. As noted, past performance is no
guarantee of future results. The indexes are statistical composites that do not
include any commissions or sales charges that would be paid by an investor
purchasing the securities represented by the indexes. Such costs would lower the
performance of the indexes. It is not possible to invest directly in an index.

Q   GIVEN THIS ENVIRONMENT OF
    HEIGHTENED DEMAND AND INDUSTRY DEREGULATION, WHAT WAS YOUR STRATEGY IN
    MANAGING THE FUND?

A   During the reporting period, we
focused primarily on power producers and natural gas. Within electricity, we
have seen demand outpace supply for the last few years because of the booming
economy--new wealth has spurred demand for comfort goods such as air
conditioners--and the Internet. When people think about the Internet and how it
has revolutionized the way we do business, it may not be obvious that all this
new technology cannot be powered without electricity. If the Internet is in fact
the backbone of the new economy, this may bode well for electric companies.

    The increased demand for electricity has benefited power producers who have
embraced deregulation. When utilities were regulated by the federal government,
it was beneficial for these companies to spend because they were guaranteed a
return on their investment. Companies built nuclear plants and windmill farms.
Now that the utilities industry is no longer regulated, companies are not
necessarily guaranteed a return on what they are spending because they must
compete for customers. The established companies have been afraid to build, and
they have not added any new electricity capacity for the past few years. That is
how some independent power producers--those that formed after deregulation--have
been able to grow so quickly. They were building new capacity when nobody else
was, and therefore had excess power generation to sell when shortages occurred.
In general, we increased the fund's exposure to these types of companies.

    As with electricity, the demand for natural gas has been greater than the
supply. In the United States, natural gas production has been declining, even
though more and more rigs are employed in the search for natural gas. The
problem is that the newly

                                        8
<PAGE>   10

discovered reserves have not been high-production reserves. Therefore, the
country's ability to produce natural gas has been declining. So, as demand has
increased, natural gas prices have increased, and the fund benefited during the
reporting period from its holdings in this industry.

Q   CAN YOU GIVE SOME EXAMPLES OF
    STOCKS THAT CONTRIBUTED TO THE FUND'S PERFORMANCE DURING THE PERIOD?

A   The best-performing stock for the
reporting period was Calpine, a domestic company that is building electricity
generation plants and is an established player in California, one of the key
areas with electricity shortages. Calpine continued to surprise with its
earnings growth and margins expansion.

    Two other independent power producers, NRG Energy and Southern Companies,
have also benefited from deregulation by selling excess power generation, and
their stock prices have increased as well. Energy producers generally performed
well during the reporting period, benefiting not only from the demands of new
technology but also from the hot summers in Texas, California, and the Midwest.

    In natural gas, Enron was a top performer for the fund. They have profited
from rising natural gas prices and have recently expanded into other
commodities, including bandwidth.

    Keep in mind that not all stocks in the fund performed well, nor is there
any guarantee that these stocks will perform as well or will be held by the fund
in the future.

Q   WHAT AREAS HAVE BEEN WEAK FOR
    THE FUND?

A   In general, telecommunications
has been a weak area of the utilities market recently, and we have cut back on
the fund's telecommunications exposure. After questions arose last spring about
the sustainability of technology and telecommunications valuations, we have seen
a slowdown in telecommunications growth as investors became concerned about that
sector. Disappointments during the reporting period included Neon Communications
(a fiber-optic network operator), Sprint (a local, long-distance, and wireless
telephone service provider), and CoreComm (a local and long-distance telephone
and Internet access provider).

Q   WHAT IS YOUR OUTLOOK FOR THE
    UPCOMING MONTHS?

A   We believe electricity demand will
continue to be strong, while supply may lag, and therefore companies that can
exploit the shortages during the winter may profit. Of course, we could have a
mild winter, and power producers may not see the profits they expect.
Regardless, we anticipate natural gas prices to continue to be higher than
average because there may not be enough oil to offset demand. Although the
telecommunications industry has suffered recently, we believe it may be only a
matter of time before the weaker players are flushed out and investor demand
picks up again.

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Utility Fund (the "Fund") is organized as a series of the Van Kampen
Equity Trust, a Delaware business trust, and is registered as a diversified
open-end management investment company under the Investment Company Act of 1940,
as amended. The Fund's investment objective is to seek to provide its
shareholders with capital appreciation and current income, through investment in
common stocks and income securities of companies engaged in the utilities
industry. The Fund commenced investment operations on July 28, 1993, with two
classes of common shares, Class A and Class B shares. The distribution of the
Fund's Class C shares commenced on August 13, 1993.

    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

A. SECURITY VALUATION Portfolio securities are valued by using market quotations
or prices provided by market makers. Any securities for which current market
quotations are not readily available are valued at their fair value as
determined in good faith using procedures established by the Board of Trustees.
Securities with remaining maturities of 60 days or less are valued at amortized
cost, which approximates market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may invest in repurchase agreements, which are short-term investments in
which the Fund acquires ownership of a debt security and the seller agrees to
repurchase the security at a future time and specified price. The Fund may
invest independently in repurchase agreements, or transfer uninvested cash
balances into a pooled cash account along with other investment companies
advised by Van Kampen Investment Advisory Corp. (the "Adviser") or its
affiliates, the daily aggregate of which is invested in repurchase agreements.
Repurchase agreements are fully collateralized by the underlying debt security.
The Fund will make payment for such securities only upon physical delivery or
evidence of book entry transfer to the account of the custodian bank. The seller
is required to maintain the value of the underlying security at not less than
the repurchase proceeds due the Fund.

C. INCOME AND EXPENSES Dividend income is recorded net of applicable withholding
taxes on the ex-dividend date; interest income is recorded on an accrual basis.
Bond discount is accreted over the expected life of each applicable security.
Income and expenses of the Fund are allocated on a pro rata basis to each class
of shares, except for distribution and service fees and transfer agency costs
which are unique to each class of shares.

D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.

    At September 30, 2000, for federal income tax purposes the cost of long- and
short-term investments is $184,801,245, the aggregate gross unrealized
appreciation is $94,377,522 and the aggregate gross unrealized depreciation is
$6,468,572, resulting in net unrealized appreciation on long- and short-term
investments of $87,908,950.

E. DISTRIBUTION OF INCOME AND GAINS The Fund declares and pays dividends
quarterly from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains and gains on option and futures
transactions. All short-term capital gains and a portion of option and futures
gains are included as ordinary income for tax purposes.

    Due to inherent differences in the recognition of expenses under generally
accepted accounting principles and federal income tax purposes, the amount of
distributed net investment income may differ for a particular period. These
differences are temporary in nature, but may result in book basis distribution
in excess of net investment income for certain periods.

F. EXPENSE REDUCTIONS During the six months ended September 30, 2000, the Fund's
custody fee was reduced by $4,756 as a result of credits earned on overnight
cash balances.

</TABLE>

    For the six months ended September 30, 2000, the Fund recognized expenses of
approximately $4,300 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom (Illinois), counsel to the Fund, of which a trustee of the
Fund is an affiliated person.

    For the six months ended September 30, 2000, the Fund recognized expenses of
approximately $17,900 representing Van Kampen's cost of providing accounting and
legal services to the Fund.

    Van Kampen Investor Services Inc., an affiliate of the Adviser, serves as
the shareholder servicing agent of the Fund. For the six months ended September
30, 2000, the Fund recognized expenses of approximately $95,300. Transfer agency
fees are determined through negotiations with the Fund's Board of Trustees and
are based on competitive market benchmarks.

    Certain officers and trustees of the Fund are also officers and directors of
Van Kampen. The Fund does not compensate its officers or trustees who are
officers of Van Kampen.

    The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation to a
later date. Benefits under the retirement plan are payable for a ten-year period
and are based upon each trustee's years of service to the Fund. The maximum
annual benefit per trustee under the plan is $2,500.

5. DISTRIBUTION AND SERVICE PLANS

The Fund and its shareholders have adopted a distribution plan pursuant to Rule
12b-1 under the Investment Company Act of 1940, as amended, and a service plan
(collectively the "Plans"). The Plans govern payments for the distribution of
the Fund's shares, ongoing shareholder services and maintenance of shareholder
accounts.

    Annual fees under the Plans of up to .25% for Class A net assets and 1.00%
each for Class B and Class C net assets are accrued daily. Included in these
fees for the six months ended September 30, 2000, are payments retained by Van
Kampen of approximately $311,700.

6. BORROWINGS

In accordance with its investment policies, the Fund may borrow from banks for
temporary purposes and is subject to certain other customary restrictions.
Effective November 30, 1999, the Fund, in conjunction with certain other funds
of Van Kampen, has entered in to a $650,000,000 committed line of credit
facility with a group of banks which expires on November 28, 2000, but is
renewable with the consent of the participating banks. Each fund is permitted to
utilize the facility in accordance with the restrictions of its prospectus. In
the event the demand for the credit facility meets or exceeds $650 million on a
complex-wide basis, each fund will be limited to its pro-rata percentage based
on the net assets of each participating fund. Interest on borrowings is charged
under the agreement at a rate of 0.50% above the federal funds rate per annum.
An annual commitment fee of 0.09% per annum is charged on the unused portion of
the credit facility, which each fund incurs based on its pro-rata percentage of
quarterly net assets. The Fund has not borrowed against the credit facility
during the period.

 OVERVIEW

LETTER TO SHAREHOLDERS
October 20, 2000

Dear Shareholder,
The first three quarters of 2000 proved to be especially volatile, with all of
the major markets declining in the spring and spending the following months
trying to recover. To manage one's portfolio during such unpredictable times
requires investment-management experience, and the following pages should give
you some insight into how we have performed in this difficult environment.

In this report, the portfolio managers will explain how your investment
performed during the reporting period and describe the strategies they used to
manage your fund during that span. The report will also show you how your
investment has performed over time. Helpful charts summarize the fund's largest
investments, and you can examine the complete portfolio to see all of your
fund's holdings as of the end of your fund's reporting period.

                  At Van Kampen, we place a high priority on providing you and
                  your financial advisor with the information you need to help
                  you monitor your investments during all types of markets. With
nearly four generations of investment-management experience, we've been around
long enough to understand that by investing with Van Kampen you're entrusting us
with much more than your money. Your investments may help make it possible to
afford your next house, keep up with rising college costs, or enjoy a
comfortable retirement.

No matter what your reasons for investing, we're thankful that you've chosen to
place your investments with Van Kampen. We will continue to apply our
generations of money-management experience to helping you pursue life's true
wealth.

Sincerely,

[SIG]
Richard F. Powers, III
President and CEO
Van Kampen Investments

ECONOMIC SNAPSHOT

ECONOMIC GROWTH
ECONOMIC GROWTH WAS STRONG DURING THE REPORTING PERIOD, UNDERPINNED BY LOW
UNEMPLOYMENT AND RISING PRODUCTIVITY, YET THERE WERE SIGNS THAT A HEALTHY
SLOWDOWN WAS UNDERWAY. GROSS DOMESTIC PRODUCT, THE PRIMARY MEASURE OF ECONOMIC
GROWTH, INCREASED AT A 2.7 PERCENT ANNUALIZED RATE FOR THE THIRD QUARTER OF
2000. FOLLOWING MILD FIRST- AND SECOND-QUARTER DATA, THIS THIRD-QUARTER FIGURE
OFFERS FURTHER EVIDENCE THAT GROWTH MIGHT BE SETTLING BACK TO A MORE MODERATE
AND SUSTAINABLE PACE THAN ITS RAPID RATE IN LATE 1999.

CONSUMER SPENDING AND EMPLOYMENT
CONCERNS ABOUT INFLATION REMAINED AT BAY DUE IN PART TO A GRADUAL SLOWDOWN IN
CONSUMER SPENDING. RISING INTEREST RATES, HIGHER ENERGY COSTS, AND A
DISAPPOINTING STOCK MARKET BEGAN TO TEMPER RETAIL SALES, WHICH LEVELED OFF FROM
THE BLISTERING PACE OF LATE 1999 AND EARLY 2000. AND WHILE CONSUMER SPENDING WAS
BRISK, THE OVERALL TREND HAS BEEN DOWNWARD THIS YEAR.

THE JOBLESS RATE CONTINUED TO BE EXTREMELY LOW BY HISTORICAL STANDARDS, BUT
RECENT CUTS IN MANUFACTURING PAYROLLS SUPPORT THE POPULAR BELIEF THAT THE
ECONOMY IS MODERATING. ALTHOUGH EMPLOYER COSTS SUCH AS WAGES AND BENEFITS WERE
RISING AT THE END OF 1999 AND IN THE BEGINNING OF 2000, OVER THE PAST SIX MONTHS
THE EMPLOYMENT COST INDEX HAS SHOWN MARKED DECELERATION, WHICH SHOULD HELP EASE
INFLATION CONCERNS.

INTEREST RATES AND INFLATION
THE FEDERAL RESERVE BOARD (THE FED) RAISED INTEREST RATES FOUR TIMES DURING THE
LAST 12 MONTHS IN AN EFFORT TO WARD OFF INFLATION BY CURBING ECONOMIC GROWTH.
OVER THE SAME PERIOD, THE CONSUMER PRICE INDEX ROSE 3.5 PERCENT, WHICH INDICATED
THAT INFLATION GENERALLY REMAINS UNDER CONTROL.

THE FED HAS ACKNOWLEDGED THE RISK OF RISING INFLATION AND WILL STAY ON GUARD, AS
RISING ENERGY COSTS AND LOW UNEMPLOYMENT THREATEN TO PROPEL THIS FIGURE UPWARD
IN THE COMING MONTHS. AS LONG AS INFLATION IS CONTAINED AND THE PACE OF ECONOMIC
GROWTH REMAINS FAVORABLE, THE FED IS LIKELY TO HOLD INTEREST RATES STEADY IN THE
SHORT TERM, WHICH COULD HELP STABILIZE THE STOCK AND BOND MARKETS.

(1) Assumes reinvestment of all distributions for the period and does not
    include payment of the maximum sales charge (5.75% for Class A Shares) or
    contingent deferred sales charge ("CDSC"). On purchases of Class A Shares of
    $1 million or more, a CDSC of 1% may be imposed on certain redemptions made
    within one year of purchase. Returns for Class B Shares are calculated
    without the effect of the maximum 5% CDSC, charged on certain redemptions
    made within one year of purchase and declining to 0% after the fifth year.
    Returns for Class C Shares are calculated without the effect of the maximum
    1% CDSC, charged on certain redemptions made within one year of purchase. If
    the sales charges were included, total returns would be lower.

(2) Standardized total return. Assumes reinvestment of all distributions for the
    period and includes payment of the maximum sales charge (5.75% for Class A
    Shares) or contingent deferred sales charge ("CDSC"). On purchases of Class
    A Shares of $1 million or more, a CDSC of 1% may be imposed on certain
    redemptions made within one year of purchase. Returns for Class B Shares are
    calculated with the effect of the maximum 5% CDSC, charged on certain
    redemptions made within one year of purchase and declining to 0% after the
    fifth year. Returns for Class C Shares are calculated with the effect of the
    maximum 1% CDSC, charged on certain redemptions made within one year of
    purchase.

    The Fund's performance during the period was largely attributable to
    investments in the technology sector, which performed favorably for the
    period. Additionally, securities purchased during initial public offerings
    contributed to the Fund's return. There is no guarantee that this
    performance record or the circumstances leading to it can be replicated in
    the future.

    An investment in the Fund is subject to investment risks, and you could lose
    money on your investment in the Fund. Please review the Risk/Return Summary
    of the Prospectus for further details on investment risks. Fund shares, when
    redeemed, may be worth more or less than their original cost. Past
    performance is no guarantee of future results. Investment return and net
    asset value will fluctuate with market conditions.

    Although the Fund may invest its assets in securities of larger sized
    companies, the Fund invests primarily in equity securities of small- and
    mid-sized companies. These types of companies may have limited product
    lines, markets or financial resources and their securities may be subject to
    more erratic market movements than those of larger companies. Foreign
    investments may magnify volatility due to changes in foreign exchange rates,
    the political and economic uncertainties in foreign countries, and the
    potential lack of liquidity, government supervision, and regulation.

    Market forecasts provided in this report may not necessarily come to pass.

Q   WERE YOU PLEASED WITH THE
    FUND'S PERFORMANCE OVER THE PAST SIX MONTHS, CONSIDERING THE MARKET
    CONDITIONS YOU WERE UP AGAINST?

A   It is safe to say we were pleased
but not entirely satisfied. Although the fund's return of -5.05 percent
outperformed the Russell 2500(R) Growth Index, it underperformed the Russell
2000(R) Index, for the six months ended September 30, 2000 (Class A shares at
net asset value; if the maximum sales charge of 5.75 percent were included, the
return would have been lower). Past performance is no guarantee of future
results, and as a result of recent market activity, fund performance may vary
from the figures shown. By comparison, the Russell 2000(R) Index returned -2.68
percent, and the Russell 2500(R) Growth Index, which more closely resembles the
fund, returned -9.65 percent. The Russell 2000(R) Index reflects the general
performance of small-cap stocks, and the Russell 2500(R) Growth Index measures
the performance of those Russell 2500(R) companies with higher price-to-book
ratios and higher forecasted growth values. These indexes are statistical
composites that do not include any commissions or sales charges that would be
paid by an investor purchasing the securities they represent. Such costs would
lower the performance of the indexes. It is not possible to invest directly in
an index. Please refer to the chart and footnotes on page 4 for additional fund
performance results.

    The fund recovered quite nicely from the significant market correction that
took place in the spring. The first two months of the fiscal year, April and May
of 2000, saw sharp declines in

                                        7
<PAGE>   39

stock prices, especially in the technology-laden NASDAQ index, which dipped
close to 3000 in late May, down from its peak of 5048 on March 10. Some of the
selling was simple profit-taking, as investors took advantage of the run-up in
prices that occurred between October 1999 and March 2000 and reacted to the
notion that stock valuations had reached unjustifiably high levels.

    Another important factor in the sell-off was the Federal Reserve Board's
push to control the growth rate of the economy and keep inflation in check.
Concerned that brisk economic growth would ignite inflation, the Fed hiked key
short-term interest rates four times over the past year, the last increase
coming in May 2000. Many investors worried that rising interest rates would slow
the economy, dampen business investment and consumer spending, and put pressure
on corporate earnings.

    These fears hit some of the more speculative stocks in the technology sector
especially hard. Many of these stocks were trading at lofty valuations, some
with triple-digit price-to-earnings ratios. When investors sensed that corporate
earnings might be squeezed, they bailed out of what they considered to be the
most vulnerable stocks.

    Prices have recovered somewhat since then, though we continue to see
volatility as the market tries to gauge the impact of rising interest rates,
higher commodities prices, and other factors. Corporate earnings are once again
in the spotlight, as investors are favoring companies with more visible, more
reliable earnings prospects.

    Even though the fund is weighted primarily in technology stocks, we believe
our strategy has positioned the fund to hold stocks that may offer excellent
potential in the current market environment. We try to anticipate a firm's
earnings potential, seeking out those with rising earnings expectations and
rising valuations, because these are the stocks the market has historically
rewarded with higher prices.

Q   THE FUND WAS REOPENED TO NEW
    INVESTORS ON MAY 1, 2000, AFTER HAVING BEEN CLOSED TO NEW INVESTORS SINCE
    DECEMBER 1999. WERE YOU CONCERNED THAT THE FUND WAS REOPENING DURING A
    DIFFICULT TIME FOR THE STOCK MARKET, AND DID IT AFFECT YOUR APPROACH?

A   We weren't concerned about the
timing of the fund's reopening because we believe our approach is solid. We
decided to reopen the fund because we sensed that the explosion in new
technologies was still in its early stages. Telecommunications, e-commerce, and
other technologically advanced sectors of the economy were on the verge of
breakthroughs that had the potential to spur demand and accelerate the pace at
which these industries develop. We wanted to be in a position to participate in
the investment opportunities that may emerge as we identify the companies that
could benefit from this expansion.

    The most significant adjustment to the portfolio was to broaden the fund's
focus to include stocks with larger

                                        8
<PAGE>   40

market capitalizations. While the fund could always invest in companies of any
size, it had previously focused on small and mid-sized companies. But with the
rapid growth of the market, many of these firms are now much larger in terms of
capitalization. Also, the net assets of the fund have been expanding, making it
difficult to invest strictly in smaller companies while still remaining true to
the fund's approach of selecting companies based on rising earnings expectations
and rising valuations. So, we thought it seemed to be the right time to reopen
the fund, and we remain confident in the fund's investment approach.

Q   HAS THIS BROADENING FOCUS
SIGNIFICANTLY CHANGED THE COMPOSITION OF THE FUND'S INVESTMENTS?

A   No, not significantly. The fund
remained heavily invested in the technology sector during the reporting period.
In fact, 8 of the fund's top 10 holdings were in technology, representing 21
percent of the fund's long-term investments. This is a market sector that, in
our opinion, continues to hold promise as demand rises for wireless
telecommunications, broad-bandwidth data traffic, and Internet-based commerce
software and services.

    We also believed the health-care sector offered a number of opportunities.
For example, certain specialty pharmaceutical companies stand to benefit from
the aging population, the expiration of competitors' drug patents, and a strong
pipeline of new products. One such company, Alza, is among the fund's top 10
holdings.

    Another area we liked was the energy sector, including the drilling, oil
services, and power-producer industries. Strong demand has driven up the prices
of crude oil and natural gas amid shrinking inventories and supply shortages.
Calpine, an independent power producer, is one of the fund's top 15 holdings.

Q   WHAT ARE SOME OF THE STOCKS
    THAT PERFORMED WELL FOR THE FUND?

A   In the technology portion of the
portfolio, we saw strong performance from Integrated Device Technology, a
manufacturer of semiconductors; Newport, a maker of capital equipment for the
manufacture of optical network components; and Extreme Networks, a network
equipment and consulting firm. All of these companies benefited from the
explosion in Internet traffic and the growing need for data exchange and
storage.

    Strong health-care stocks included medical testing firm Quest Diagnostics
and pharmaceutical makers Alza and Ivax. We also benefited from the solid
performance of Noble Drilling and Nabors Industries in the oil services field.

    Of course, not all of the stocks in the fund performed as favorably, nor is
there any guarantee that any of these stocks will continue to perform or will be
held by the fund in the future. For additional fund highlights, please refer to
page 6.

<PAGE>   41

Q   WHICH STOCKS PERFORMED BELOW
    YOUR EXPECTATIONS DURING THE PERIOD?

A   The fund had weak performance
from two of its semiconductor capital equipment stocks, Varian and KLA-Tencor,
due to the industry's declining book-to-bill ratio--a measure of the
semiconductor industry's health--and expectations of lower corporate spending on
computers and other components. Vishay Intertechnology and AVX Corporation, both
of which make electronic components such as capacitors and resistors for cell
phones, VCRs, and photocopiers, were hurt by overcapacity and falling prices.

    The fund was also stung when Motorola and Nokia missed quarterly earnings
estimates. The fund did not own these stocks, but their weaker-than-expected
earnings affected the prices of other related stocks that the fund held at the
time. Alpha Industries and Anadigics, for example, are wireless component
suppliers that were hurt by the disappointing earnings of Motorola and Nokia and
by declining sales estimates for handheld cellular phones.

Q   WHAT IS YOUR OUTLOOK FOR
    THE MARKET?

A   Overall, we are bullish on the
stock market, especially the technology sector. In the short term, investors
will likely continue to focus on corporate earnings. The fourth quarter of 2000
started with profit warnings from traditional technology bellwethers, which
triggered a fairly severe sell-off among these stocks. We anticipate that the
market may move into a more favorable environment over the rest of the year.

    We believe the Federal Reserve Board may hold interest rates steady at the
next meeting of the Federal Open Market Committee. The market appears to be
anticipating no further rate increases until next year, as the economy appears
to be growing more slowly with inflation under control.

    We expect to keep the fund fully invested, with only about 2 percent of its
assets in cash and a very similar portfolio composition to what we have now.
This includes an emphasis on technology stocks that should benefit from Internet
usage, computer networking, and e-commerce. We will continue to let our
investment process point the way to stocks that are likely to be rewarded in
this environment, as we rely heavily on our research capabilities to identify
the stocks that will be powered by strong earnings expectations and rising
valuations.

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Aggressive Growth Fund (the "Fund") is organized as a separate
diversified series of Van Kampen Equity Trust (the "Trust"), a Delaware business
trust, which is registered as an open-end management investment company under
the Investment Company Act of 1940, as amended. The Fund's investment objective
is to seek capital growth. The Fund commenced investment operations on May 29,
1996 with three classes of common shares, Class A, Class B and Class C.

    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

A. SECURITY VALUATION Investments in securities listed on a securities exchange
are valued at their sale price as of the close of such securities exchange.
Unlisted securities and listed securities for which the last sales price is not
available are valued at the mean of the bid and asked prices. For those
securities where quotations or prices are not available, valuations are
determined in accordance with procedures established in good faith by the Board
of Trustees. Short-term securities with remaining maturities of 60 days or less
are valued at amortized cost, which approximates market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.

    The Fund may invest in repurchase agreements which are short-term
investments in which the Fund acquires ownership of a debt security and the
seller agrees to repurchase the security at a future time and specified price.
The Fund may invest independently in repurchase agreements, or transfer
uninvested cash balances into a pooled cash account along with other investment
companies advised by Van Kampen Investment Advisory Corp. (the "Adviser") or its
affiliates, the daily aggregate of which is invested in repurchase agreements.
Repurchase agreements are collateralized by the underlying debt security. The
Fund will make payment for such securities only upon physical delivery or
evidence of book entry transfer to the account of the custodian bank. The seller
is required to maintain

the value of the underlying security at not less than the repurchase proceeds
due the Fund.

C. INCOME AND EXPENSES Dividend income is recorded on the ex-dividend date and
interest income is recorded on an accrual basis. Income and expenses of the Fund
are allocated on a pro rata basis to each class of shares, except for
distribution and service fees and transfer agency costs which are unique to each
class of shares.

D. ORGANIZATIONAL COSTS The Fund will reimburse Van Kampen Funds Inc. or its
affiliates (collectively "Van Kampen") for costs incurred in connection with the
Fund's organization in the amount of $105,000. These costs are being amortized
on a straight line basis over the 60 month period ending May 28, 2001. The
Adviser has agreed that in the event any of the initial shares of the Fund
originally purchased by Van Kampen are redeemed by the Fund during the
amortization period, the Fund will be reimbursed for any unamortized
organizational costs in the same proportion as the number of shares redeemed
bears to the number of initial shares held at the time of redemption.

E. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.

    At September 30, 2000, for federal income tax purposes, cost of long- and
short-term investments is $2,031,632,492; the aggregate gross unrealized
appreciation is $749,114,587 and the aggregate gross unrealized depreciation is
$26,180,148, resulting in net unrealized appreciation on long- and short-term
investments of $722,934,439.

F. DISTRIBUTION OF INCOME AND GAINS The Fund declares and pays dividends
annually from net investment income and net realized gains, if any. For federal
income tax purposes, a net investment loss recognized in the current year cannot
be used to offset future years net investment income. Therefore, tax basis net
investment losses are reclassified to capital at the end of the Fund's fiscal
year.

G. EXPENSE REDUCTIONS During the six months ended September 30, 2000, the Fund's
custody fee was reduced by $61,226 as a result of credits earned on overnight
cash balances.

Van Kampen. The Fund does not compensate its officers or trustees who are
officers of Van Kampen.

    The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation to a
later date. Benefits under the retirement plan are payable for a ten-year period
and are based upon each trustee's years of service to the Fund. The maximum
annual benefit per trustee under the plan is $2,500.

net assets. The Fund has not borrowed against the credit facility during the

 OVERVIEW

LETTER TO SHAREHOLDERS
October 20, 2000

Dear Shareholder,

The first three quarters of 2000 proved to be especially volatile, with all of
the major markets declining in the spring and spending the following months
trying to recover. To manage one's portfolio during such unpredictable times
requires investment-management experience, and the following pages should give
you some insight into how we have performed in this difficult environment.

In this report, the portfolio managers will explain how your investment
performed during the reporting period and describe the strategies they used to
manage your fund during that span. The report will also show you how your
investment has performed over time. Helpful charts summarize the fund's largest
investments, and you can examine the complete portfolio to see all of your
fund's holdings as of the end of your fund's reporting period.

                  At Van Kampen, we place a high priority on providing you and
                  your financial advisor with the information you need to help
                  you monitor your investments during all types of markets. With
                  nearly four generations of investment-management experience,
                  we've been around long enough to understand that by investing
with Van Kampen you're entrusting us with much more than your money. Your
investments may help make it possible to afford your next house, keep up with
rising college costs, or enjoy a comfortable retirement.

No matter what your reasons for investing, we're thankful that you've chosen to
place your investments with Van Kampen. We will continue to apply our
generations of money-management experience to helping you pursue life's true
wealth.

Sincerely,

[SIG]

ECONOMIC SNAPSHOT

ECONOMIC GROWTH
ECONOMIC GROWTH WAS STRONG DURING THE REPORTING PERIOD, UNDERPINNED BY LOW
UNEMPLOYMENT AND RISING PRODUCTIVITY, YET THERE WERE SIGNS THAT A HEALTHY
SLOWDOWN WAS UNDERWAY. GROSS DOMESTIC PRODUCT, THE PRIMARY MEASURE OF ECONOMIC
GROWTH, INCREASED AT A 2.7 PERCENT ANNUALIZED RATE FOR THE THIRD QUARTER OF
2000. FOLLOWING MILD FIRST- AND SECOND-QUARTER DATA, THIS THIRD-QUARTER FIGURE
OFFERS FURTHER EVIDENCE THAT GROWTH MIGHT BE SETTLING BACK TO A MORE MODERATE
AND SUSTAINABLE PACE THAN ITS RAPID RATE IN LATE 1999.

CONSUMER SPENDING AND EMPLOYMENT
CONCERNS ABOUT INFLATION REMAINED AT BAY DUE IN PART TO A GRADUAL SLOWDOWN IN
CONSUMER SPENDING. RISING INTEREST RATES, HIGHER ENERGY COSTS, AND A
DISAPPOINTING STOCK MARKET BEGAN TO TEMPER RETAIL SALES, WHICH LEVELED OFF FROM
THE BLISTERING PACE OF LATE 1999 AND EARLY 2000. AND WHILE CONSUMER SPENDING WAS
BRISK, THE OVERALL TREND HAS BEEN DOWNWARD THIS YEAR.

THE JOBLESS RATE CONTINUED TO BE EXTREMELY LOW BY HISTORICAL STANDARDS, BUT
RECENT CUTS IN MANUFACTURING PAYROLLS SUPPORT THE POPULAR BELIEF THAT THE
ECONOMY IS MODERATING. ALTHOUGH EMPLOYER COSTS SUCH AS WAGES AND BENEFITS WERE
RISING AT THE END OF 1999 AND IN THE BEGINNING OF 2000, OVER THE PAST SIX MONTHS
THE EMPLOYMENT COST INDEX HAS SHOWN MARKED DECELERATION, WHICH SHOULD HELP EASE
INFLATION CONCERNS.

INTEREST RATES AND INFLATION
THE FEDERAL RESERVE BOARD (THE FED) RAISED INTEREST RATES FOUR TIMES DURING THE
LAST 12 MONTHS IN AN EFFORT TO WARD OFF INFLATION BY CURBING ECONOMIC GROWTH.
OVER THE SAME PERIOD, THE CONSUMER PRICE INDEX ROSE 3.5 PERCENT, WHICH INDICATED
THAT INFLATION GENERALLY REMAINS UNDER CONTROL.

THE FED HAS ACKNOWLEDGED THE RISK OF RISING INFLATION AND WILL STAY ON GUARD, AS
RISING ENERGY COSTS AND LOW UNEMPLOYMENT THREATEN TO PROPEL THIS FIGURE UPWARD
IN THE COMING MONTHS. AS LONG AS INFLATION IS CONTAINED AND THE PACE OF ECONOMIC
GROWTH REMAINS FAVORABLE, THE FED IS LIKELY TO HOLD INTEREST RATES STEADY IN THE
SHORT TERM, WHICH COULD HELP STABILIZE THE STOCK AND BOND MARKETS.

(1) Assumes reinvestment of all distributions for the period and does not
    include payment of the maximum sales charge (5.75% for Class A Shares) or
    contingent deferred sales charge ("CDSC") for Class B and Class C Shares. On
    purchases of Class A Shares of $1 million or more, a CDSC of 1% may be
    imposed on certain redemptions made within one year of purchase. Returns for
    Class B Shares are calculated without the effect of the maximum 5% CDSC,
    charged on certain redemptions made within one year of purchase and
    declining to 0% after the fifth year. Returns for Class C Shares are
    calculated without the effect of the maximum 1% CDSC, charged on certain
    redemptions made within one year of purchase. If the sales charges were
    included, total returns would be lower. These returns do include Rule 12b-1
    fees of up to .25% for Class A Shares and 1% for Class B and Class C Shares.

(2) Standardized total return. Assumes reinvestment of all distributions for the
    period and includes payment of the maximum sales charge (5.75% for Class A
    Shares) or contingent deferred sales charge ("CDSC") for Class B and Class C
    Shares and Rule 12b-1 fee. On purchases of Class A Shares of $1 million or
    more, a CDSC of 1% may be imposed on certain redemptions made within one
    year of purchase. Returns of Class B Shares are calculated with the effect
    of the maximum 5% CDSC, charged on certain redemptions made within one year
    of purchase and declining to 0% after the fifth year. Returns for Class C
    Shares are calculated with the effect of the maximum 1% CDSC, charged on
    certain redemptions made within one year of purchase. The Rule 12b-1 fee for
    Class A Shares is up to .25% and for Class B and Class C Shares is 1%.

    An investment in the Fund is subject to investment risks, and you could lose
    money on your investment in the Fund. Please review the Risk/Return Summary
    of the Prospectus for further details on investment risks. Fund shares, when
    redeemed, may be worth more or less than their original cost. Past
    performance is no guarantee of future results. Investment return and net
    asset value will fluctuate with market conditions.

    From the Fund's inception through the period ended September 30, 1999,
    certain fees were waived and expenses were voluntarily reimbursed by the
    Fund's adviser which had a material effect on the Fund's total return. Had
    these fees not been waived and expenses reimbursed, the Fund's total return
    would have been lower. The fee waiver and expense reimbursements were
    voluntary in nature and have been discontinued at the Advisor's discretion.

    One factor impacting the Fund's total return for the life of the Fund was
    the Fund's investments in initial public offerings (IPOs) in 1996. These
    investments had a greater effect on fund performance in 1996 than similar
    investments made in subsequent years, in part because of the smaller size of
    the Fund in 1996. There is no assurance that the Fund's future investments
    in IPOs will have the same impact on performance as occurred in 1996.

    The Fund's investments in less seasoned companies, special situations
    involving new management, special projects and techniques, unusual
    developments, mergers, or liquidations involve greater risks than more
    conservative investments. Securities of foreign issuers may magnify
    volatility of the Fund's portfolio due to changes in foreign exchange rates,
    the political and economic uncertainties in foreign countries, and the
    potential lack of liquidity, government supervision, and regulation.

    Market forecasts provided in this report may not necessarily come to pass.

Q&A WITH YOUR PORTFOLIO MANAGERS

WE RECENTLY SPOKE WITH THE MANAGEMENT TEAM OF THE VAN KAMPEN GROWTH FUND ABOUT
THE KEY EVENTS AND ECONOMIC FORCES THAT SHAPED THE MARKETS AND INFLUENCED THE
FUND'S RETURN DURING THE SIX MONTHS ENDED SEPTEMBER 30, 2000. THE TEAM IS LED BY
JEFF D. NEW, SENIOR PORTFOLIO MANAGER, WHO HAS MANAGED THE FUND SINCE ITS
INCEPTION IN DECEMBER 1995 AND HAS WORKED IN THE INVESTMENT INDUSTRY SINCE 1987.
HE IS JOINED BY MICHAEL DAVIS AND MARY JAYNE MALY, SENIOR PORTFOLIO MANAGERS.
THE FOLLOWING DISCUSSION REFLECTS THEIR VIEWS ON THE FUND'S PERFORMANCE.

Q   HOW WOULD YOU CHARACTERIZE THE
    MARKET CONDITIONS DURING THE PAST SIX MONTHS, AND TO WHAT DO YOU ATTRIBUTE
    THE FUND'S PERFORMANCE?

A   Market conditions were
challenging, but we believe the fund's portfolio was well positioned to handle
the market's volatility and declining performance. Corporate earnings were
strong during most of the period but began to slip as rising interest rates
began to curb consumer spending and as investors saw indications that the
economy might be slowing, albeit to a sustainable pace. Despite favorable
economic growth and controlled inflation, these earnings concerns contributed to
market volatility, particularly among large-capitalization growth stocks whose
valuations had been high by historical standards. However, because the fund
invests primarily in stocks of mid-size companies, which were less affected by
the volatility of the market during this period, it was able to hold its ground.

    The reporting period opened in April on a sour note, as all major market
indexes fell significantly in the spring, with technology stocks among the
hardest hit. Subsequently, speculation in the stock market began to subside. In
other words, many of the high-risk "concept" companies that had not yet
demonstrated an ability to generate earnings saw their stock prices fall
dramatically. This was especially true within the technology sector, where many
unproven "dot.com" stocks--the darlings of Wall Street in 1999--suddenly fell.
Instead, investors began to favor value stocks and more proven companies with
histories of strong earnings. The market rallied in August, but September
brought more declines across the broad market, with the technology sector
getting pummeled once again.

    The fund weathered this difficult environment competently because it did not
own the market's most speculative stocks, which fell so precipitously during the
period. Furthermore, we made a number of strategic decisions within the
technology and health-care sectors that helped fund performance.

THE MANAGERS' INVESTMENT APPROACH

WE PURCHASE STOCKS THAT MEET OUR CRITERIA OF POSITIVE FUTURE FUNDAMENTALS AND
ATTRACTIVE CURRENT PRICES. BY OUR DEFINITION, A COMPANY WITH POSITIVE FUTURE
FUNDAMENTALS HAS AT LEAST ONE OF THE FOLLOWING TRAITS: CONSISTENT EARNINGS
GROWTH; ACCELERATING EARNINGS GROWTH; BETTER-THAN-EXPECTED FUNDAMENTALS; OR AN
UNDERLYING CHANGE IN A COMPANY, INDUSTRY, OR REGULATORY ENVIRONMENT. WE EVALUATE
STOCKS USING A "BOTTOM-UP" APPROACH--IN OTHER WORDS, ON A COMPANY-BY-COMPANY
BASIS.

As a result of our favorable stock selection and the fund's strict investment
strategy, the fund returned 2.46 percent for the six months ended September 30,
2000 (Class A shares at net asset value; if the maximum sales charge of 5.75
percent were included, the return would have been lower). Due to recent market
activity, fund performance may vary from the figure shown. By comparison, the
Standard & Poor's 500 Index returned -3.60 percent. Of course, past performance
is no guarantee of future results. The S&P 500 Index is a broad-based, unmanaged
index that reflects the general performance of the stock market. It is a
statistical composite that does not include any commissions or sales charges
that would be paid by an investor purchasing the securities it represents. Such
costs would lower the performance of the index. It is not possible to invest
directly in an index. Please refer to the chart and footnotes on page 4 for
additional fund performance results.

Q   AFTER BEING CLOSED SINCE MARCH 1997, THE FUND REOPENED TO NEW INVESTORS ON
    JULY 28, 2000. HOW DID THIS AFFECT THE FUND?

A   The reopening of the fund did not affect the investment process we use to
manage the fund (see sidebar). The total assets of the fund remained relatively
low. At this time, we do not anticipate any negative impact to the fund related
to its reopening. If the fund's assets increase, there could be some benefit to
shareholders through operating efficiencies and economies of scale.

Q   WHAT IS YOUR INVESTMENT STRATEGY, AND HOW DID YOU ADJUST YOUR STRATEGY IN
    RESPONSE TO THE MARKET ENVIRONMENT?

A   Our core investment strategy remains consistent, regardless of

                                        8
<PAGE>   70

market conditions (see sidebar). When the economy slows, however, as during the
reporting period, individual companies can become vulnerable. Therefore, we are
even more determined to identify companies in the fund's portfolio that may have
slowing growth or disappointing earnings, so that we may act quickly to reduce
or sell the holding.

Q   YOU MENTIONED THAT THE PORTFOLIO WAS WELL POSITIONED--WHICH AREAS OF THE
    MARKET PRESENTED ATTRACTIVE OPPORTUNITIES?

A   The fund's largest weighting was in the technology sector, where half of the
fund's assets were invested at the end of the reporting period. Although many
technology stocks declined during the period, as we mentioned earlier many of
these were among the less-proven technology companies, including a large number
of Internet firms. We limited the fund's technology holdings to companies we
believed had a long-term ability to create earnings. The market rewarded these
stocks, so the fund's large position added to its performance.

    Health care represented a significant weighting in the portfolio, and this
was a notable change over the course of the last six months. In the early part
of the year, biotechnology stocks were extremely expensive. However, with the
volatile markets and investors abandoning these stocks in favor of more
time-tested companies, a collapse occurred among these stocks. This presented us
with a buying opportunity. We purchased several biotechnology stocks that
exhibited positive future fundamentals at prices we liked because we believed
their companies had strong business models. We believe that the stocks we
selected may benefit shareholders as investors continue to favor companies that
appear to have a long-term positive future over companies with weak business
models and unproven products.

    Finally, the fund's weighting in energy stocks remained fairly consistent
during the period, reflecting our enthusiasm for this sector. Energy prices were
high, which stimulated the demand for drilling and related services, and stock
prices have risen accordingly.

Q   CAN YOU DESCRIBE A FEW OF THE STOCKS THAT MADE THE GREATEST POSITIVE
    CONTRIBUTION TO FUND PERFORMANCE?

A   The fund's best-performing stocks came from a variety of market sectors.
They included:

- Ariba--An established leader in business-to-business Internet commerce, Ariba
  provides top global companies with the strategies and software to help them
  sell their products over the Internet. This stock is a relatively new purchase
  for the fund.

- Waters--This firm is a leading supplier of high-performance instrumentation
  used in the health-care, chemical, and environmental industries. Recent
  earnings growth has been driven primarily by pharmaceutical and biotechnology
  companies that use its products to accelerate their discovery of new drugs.

- Chico's FAS--A women's apparel retailer, Chico's has been one of the

                                        9
<PAGE>   71

  few retail stocks to deliver consistently strong earnings numbers in this
  environment of slowing consumer spending.

- Calpine--This independent power company has been expanding rapidly under
  utility deregulation. Found in the utility sector, the stock has performed as
  a "growth" utility.

- CDW Computer Center--This mail-order computer reseller caters to small and
  mid-size businesses. Thanks to its well-trained sales force, strong client
  relationships, and inventory management skills, the company has continued to
  surpass earnings estimates.

- Alza--This health-care company's recent success has been supported by Federal
  Drug Administration approval for its new drug for treating Attention Deficit
  and Hyperactivity Disorder (ADHD). Although there are other approved therapies
  for ADHD, Alza's drug has a competitive advantage in that it can be
  administered once daily, and therefore is convenient for children.

    Of course, not all of the stocks in the fund performed as favorably, nor is
there any guarantee that any of these stocks will continue to perform as well in
the future. For additional fund highlights, please refer to page 6.

Q   WHAT STOCKS HURT FUND PERFORMANCE?

A   Among the fund's worst performers were Pacific Sunwear and Whitehall
Jewelers, both retail companies that showed disappointing earnings. Pacific
Sunwear focuses on the fashion-sensitive teen market, and the company's
misjudgment of fashion trends caused it to fall short of expected earnings.
Whitehall Jewelers simply suffered from the slowing economy, as consumers began
to limit "luxury" purchases. Both stocks were sold.

    Radio One and Hispanic Broadcasting were two radio stocks that hurt the
fund's performance. Radio stocks had performed well in the recent past.
Advertising revenues for many media companies had been on the rise as Internet
firms and other thriving businesses spent advertising dollars to attract
insatiable consumers amid the strong economy. However, the cooling of economic
growth has caused a concurrent slowdown in ad spending that has been negative to
media companies. We sold the fund's holdings in these radio stocks, as well as
other media and entertainment stocks, which contributed to the large reduction
in the fund's consumer staples exposure.

    The communications services sector, which includes a broad range of
telecommunications companies, performed poorly during the period. Many of these
firms are in a capital-spending mode, and Wall Street is

                                       10
<PAGE>   72

concerned that they won't be able to generate a substantial return on this
spending, so the stocks are out of favor. We think the capital spending cycle
will go on for a while, so we are hesitant to invest in this area until we see
some good returns on investment. As such, we sold all of the fund's holdings in
this sector, including McLeods USA, an upper-Midwestern telecommunications
company.

    Also, some of the fund's semiconductor holdings performed poorly. Atmel and
LSI Logic, which were both sold from the fund's portfolio, saw price declines
during the period because of their commodity-oriented product lines. Investors
believe that these stocks are cyclical and have peaked, and their stock prices
fell as a result.

Q   DO YOU THINK THAT MARKET CONDITIONS WILL BE MORE FAVORABLE IN THE NEAR TERM?

A   Predicting the stock market is very difficult and is something we do not
focus on. Our focus is in constructing a portfolio of individual stocks that
meet our investment criteria. However, we expect a continuation of slowing
economic growth and believe that the Fed is finished raising interest rates for
now. We believe that the most likely economic scenario will be a "soft landing,"
meaning that economic growth will slow to a healthy rate of positive growth
without triggering a recession.

    Within the stock market, valuations are in better shape than in the recent
past. Stock valuations, while historically high, have come down somewhat, taking
some of the excess out of the market in sectors that had been significantly
overvalued. Internet mania probably peaked in March, and, as we mentioned
earlier, speculation in the stock market has subsided.

Q   WHAT IS YOUR OUTLOOK FOR THE FUND?

A   Given the slowing economy, it will be critical for us to identify companies
with good fundamentals and the potential to achieve their earnings targets.
We believe that the biggest risk to individual stocks--and, consequently, to the
fund--will be companies with disappointing earnings. Our strategy in managing
the fund is based largely on identifying those companies whose earnings outlooks
are positive and attainable, consistent with the investment discipline that has
provided strong fund performance over time.

NOTES TO
FINANCIAL STATEMENTS

September 30, 2000 (Unaudited)

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Growth Fund (the "Fund") is organized as a diversified series of the
Van Kampen Equity Trust, a Delaware business trust, which is registered as an
open-end management investment company under the Investment Company Act of 1940,
as amended. The Fund's investment objective is to seek capital growth. The Fund
commenced investment operations on December 27, 1995, with three classes of
common shares, Class A, Class B and Class C.

    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

A. SECURITY VALUATION Investments in securities listed on a securities exchange
are valued at their sale price as of the close of such securities exchange.
Unlisted securities and listed securities for which the last sales price is not
available are valued at the mean of the bid and asked prices. For those
securities where quotations or prices are not available, valuations are
determined in accordance with procedures established in good faith by the Board
of Trustees. Short-term securities with remaining maturities of 60 days or less
are valued at amortized cost, which approximates market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.

    The Fund may invest in repurchase agreements, which are short-term
investments whereby the Fund acquires ownership of a debt security and the
seller agrees to repurchase the security at a future time and specified price.
The Fund may invest independently in repurchase agreements, or transfer
uninvested cash balances into a pooled cash account along with other investment
companies advised by Van Kampen Investment Advisory Corp. (the "Adviser") or its
affiliates, the daily aggregate of which is invested in repurchase agreements.
Repurchase agreements are fully collateralized by the underlying debt security.
The Fund will make payment for such securities only upon physical delivery or
evidence of book entry transfer to the account of the custodian bank. The seller
is required to

maintain the value of the underlying security at not less than the repurchase
proceeds due the Fund.

C. INCOME AND EXPENSES Dividend income is recorded on the ex-dividend date and
interest income is recorded on an accrual basis. Discount on debt securities
purchased are accreted over the expected life of each applicable security.
Premiums on debt securities are not amortized. Income and expenses of the Fund
are allocated on a pro rata basis to each class of shares, except for
distribution and service fees and transfer agency costs which are unique to each
class of shares.

D. ORGANIZATIONAL COSTS The Fund has agreed to reimburse Van Kampen Funds Inc.
or its affiliates ("collectively Van Kampen") for costs incurred in connection
with the Fund's organization in the amount of $40,000. These costs are being
amortized on a straight line basis over the 60 month period ending December 27,
2000. The Adviser has agreed that in the event any of the initial shares of the
Fund originally purchased by Van Kampen are redeemed during the amortization
period, the Fund will be reimbursed for any unamortized organizational costs in
the same proportion as the number of shares redeemed bears to the number of
initial shares held at the time of redemption.

E. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.

    Net realized gains or losses may differ for financial and tax reporting
purposes as a result of losses relating to wash sale transactions.

    At September 30, 2000, for federal income tax purposes the cost of long- and
short-term investments is $187,898,320, the aggregate gross unrealized
appreciation is $84,747,068 and the aggregate gross unrealized depreciation is
$5,043,496, resulting in net unrealized appreciation on long- and short-term
investments of $79,703,572.

F. DISTRIBUTION OF INCOME AND GAINS The Fund declares and pays dividends
annually from net investment income. Net realized gains, if any, are distributed
annually. Distributions from net realized gains for book purposes may include
short-term capital gains and gains on futures transactions. All short-term
capital gains and a portion of gains on futures transactions are included in
ordinary income for tax purposes.

    For the six months ended September 30, 2000, the Fund recognized expenses of
approximately $4,300, representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom (Illinois), counsel to the Fund, of which a trustee of the
Fund is an affiliated person.

    For the six months ended September 30, 2000, the Fund recognized expenses of
approximately $21,100, representing Van Kampen's cost of providing accounting
and legal services to the Fund.

    Van Kampen Investor Services Inc., an affiliate of the Adviser, serves as
the shareholder servicing agent of the Fund. For the six months ended September
30, 2000, the Fund recognized expenses of approximately $138,700. Transfer
agency fees are determined through negotiations with the Fund's Board of
Trustees and are based on competitive market benchmarks.

    Certain officers and trustees of the Fund are also officers and directors of
Van Kampen. The Fund does not compensate its officers or trustees who are
officers of Van Kampen.

    The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation to a
later date. Benefits under the retirement plan are payable for a ten-year period
and are based upon each trustee's years of service to the Fund. The maximum
annual benefit per trustee under the plan is $2,500.

    At September 30, 2000, Van Kampen owned 7,000 shares of Class A and 1,500
shares each of Classes B and C, respectively.

6. BORROWINGS

In accordance with its investment policies, the Fund may borrow from banks for
temporary purposes and is subject to certain other customary restrictions.
Effective November 30, 1999, the Fund, in conjunction with certain other funds
of Van Kampen, has entered into a $650,000,000 committed line of credit facility
with a group of banks which expires on November 28, 2000, but is renewable with
the consent of the participating banks. Each fund is permitted to utilize the
facility in accordance with the restrictions of its prospectus. In the event the
demand for the credit facility meets or exceeds $650 million on a complex-wide
basis, each fund will be limited to its pro-rata percentage based on the net
assets of each participating fund. Interest on borrowings is charged under the
agreement at a rate of 0.50% above the federal funds rate per annum. An annual
commitment fee of 0.09% per annum is charged on the unused portion of the credit
facility, which each fund incurs based on its pro-rata percentage of quarterly
net assets. The Fund has not borrowed against the credit facility during the
period.

 OVERVIEW

LETTER TO SHAREHOLDERS
October 20, 2000

Dear Shareholder,

The first three quarters of 2000 proved to be especially volatile, with all of
the major markets declining in the spring and spending the following months
trying to recover. To manage one's portfolio during such unpredictable times
requires investment-management experience, and the following pages should give
you some insight into how we have performed in this difficult environment.

In this report, the portfolio managers will explain how your investment
performed during the reporting period and describe the strategies they used to
manage your fund during that span. The report will also show you how your
investment has performed over time. Helpful charts summarize the fund's largest
investments, and you can examine the complete portfolio to see all of your
fund's holdings as of the end of your fund's reporting period.

                  At Van Kampen, we place a high priority on providing you and
                  your financial advisor with the information you need to help
                  you monitor your investments during all types of markets. With
                  nearly four generations of investment-management experience,
                  we've been around long enough to understand that by investing
with Van Kampen you're entrusting us with much more than your money. Your
investments may help make it possible to afford your next house, keep up with
rising college costs, or enjoy a comfortable retirement.

No matter what your reasons for investing, we're thankful that you've chosen to
place your investments with Van Kampen. We will continue to apply our
generations of money-management experience to helping you pursue life's true
wealth.

Sincerely,

[SIG]
Richard F. Powers, III
President and CEO
Van Kampen Investments

ECONOMIC SNAPSHOT

ECONOMIC GROWTH
ECONOMIC GROWTH WAS STRONG DURING THE REPORTING PERIOD, UNDERPINNED BY LOW
UNEMPLOYMENT AND RISING PRODUCTIVITY, YET THERE WERE SIGNS THAT A HEALTHY
SLOWDOWN WAS UNDERWAY. GROSS DOMESTIC PRODUCT, THE PRIMARY MEASURE OF ECONOMIC
GROWTH, INCREASED AT A 2.7 PERCENT ANNUALIZED RATE FOR THE THIRD QUARTER OF
2000. FOLLOWING MILD FIRST- AND SECOND-QUARTER DATA, THIS THIRD-QUARTER FIGURE
OFFERS FURTHER EVIDENCE THAT GROWTH MIGHT BE SETTLING BACK TO A MORE MODERATE
AND SUSTAINABLE PACE THAN ITS RAPID RATE IN LATE 1999.

CONSUMER SPENDING AND EMPLOYMENT
CONCERNS ABOUT INFLATION REMAINED AT BAY DUE IN PART TO A GRADUAL SLOWDOWN IN
CONSUMER SPENDING. RISING INTEREST RATES, HIGHER ENERGY COSTS, AND A
DISAPPOINTING STOCK MARKET BEGAN TO TEMPER RETAIL SALES, WHICH LEVELED OFF FROM
THE BLISTERING PACE OF LATE 1999 AND EARLY 2000. AND WHILE CONSUMER SPENDING WAS
BRISK, THE OVERALL TREND HAS BEEN DOWNWARD THIS YEAR.

THE JOBLESS RATE CONTINUED TO BE EXTREMELY LOW BY HISTORICAL STANDARDS, BUT
RECENT CUTS IN MANUFACTURING PAYROLLS SUPPORT THE POPULAR BELIEF THAT THE
ECONOMY IS MODERATING. ALTHOUGH EMPLOYER COSTS SUCH AS WAGES AND BENEFITS WERE
RISING AT THE END OF 1999 AND IN THE BEGINNING OF 2000, OVER THE PAST SIX MONTHS
THE EMPLOYMENT COST INDEX HAS SHOWN MARKED DECELERATION, WHICH SHOULD HELP EASE
INFLATION CONCERNS.

INTEREST RATES AND INFLATION
THE FEDERAL RESERVE BOARD (THE FED) RAISED INTEREST RATES FOUR TIMES DURING THE
LAST 12 MONTHS IN AN EFFORT TO WARD OFF INFLATION BY CURBING ECONOMIC GROWTH.
OVER THE SAME PERIOD, THE CONSUMER PRICE INDEX ROSE 3.5 PERCENT, WHICH INDICATED
THAT INFLATION GENERALLY REMAINS UNDER CONTROL.

THE FED HAS ACKNOWLEDGED THE RISK OF RISING INFLATION AND WILL STAY ON GUARD, AS
RISING ENERGY COSTS AND LOW UNEMPLOYMENT THREATEN TO PROPEL THIS FIGURE UPWARD
IN THE COMING MONTHS. AS LONG AS INFLATION IS CONTAINED AND THE PACE OF ECONOMIC
GROWTH REMAINS FAVORABLE, THE FED IS LIKELY TO HOLD INTEREST RATES STEADY IN THE
SHORT TERM, WHICH COULD HELP STABILIZE THE STOCK AND BOND MARKETS.

(1) Assumes reinvestment of all distributions for the period and does not
    include payment of the maximum sales charge (5.75% for Class A shares) or
    contingent deferred sales charge ("CDSC") for Class B and C shares. On
    purchases of Class A shares of $1 million or more, a CDSC of 1% may be
    imposed on certain redemptions made within one year of purchase. Returns for
    Class B shares are calculated without the effect of the maximum 5% CDSC,
    charged on certain redemptions made within one year of purchase and
    declining to 0% after the fifth year. Returns for Class C shares are
    calculated without the effect of the maximum 1% CDSC, charged on certain
    redemptions made within one year of purchase. If the sales charges were
    included, total returns would be lower. These returns do include Rule 12b-1
    fees of up to .25% for Class A Shares and 1% for Class B and Class C Shares.

(2) Standardized total return. Assumes reinvestment of all distributions for the
    period and includes payment of the maximum sales charge (5.75% for Class A
    shares) or contingent deferred sales charge ("CDSC") for Class B and C
    shares and Rule 12b-1 fee. On purchases of Class A shares of $1 million or
    more, a CDSC of 1% may be imposed on certain redemptions made within one
    year of purchase. Returns for Class B shares are calculated with the effect
    of the maximum 5% CDSC, charged on certain redemptions made within one year
    of purchase and declining to 0% after the fifth year. Returns for Class C
    shares are calculated with the effect of the maximum 1% CDSC, charged on
    certain redemptions made within one year of purchase. The Rule 12b-1 fee for
    Class A Shares is up to .25% and for Class B and Class C Shares is 1%.

Q&A WITH YOUR PORTFOLIO MANAGERS

WE RECENTLY SPOKE WITH THE MANAGEMENT TEAM OF THE VAN KAMPEN SMALL CAP
VALUE FUND ABOUT THE KEY EVENTS AND ECONOMIC FORCES THAT SHAPED THE MARKETS AND
INFLUENCED THE FUND'S RETURN DURING THE SIX MONTHS ENDED SEPTEMBER 30, 2000. THE
TEAM IS LED BY JOHN CUNNIFF, SENIOR PORTFOLIO MANAGER, WHO HAS MANAGED THE FUND
SINCE ITS INCEPTION IN JUNE 1999, AND HAS WORKED IN THE INVESTMENT INDUSTRY
SINCE 1992. THE FOLLOWING DISCUSSION REFLECTS HIS VIEWS ON THE FUND'S
PERFORMANCE.

Q   HOW WOULD YOU CHARACTERIZE
    THE MARKET DURING THE REPORTING PERIOD, AND TO WHAT DO YOU ATTRIBUTE THE
    FUND'S PERFORMANCE?

A   Investors saw record volatility in
the stock market. The technology sell-off in the spring helped take some of the
speculation out of the market by punishing high-valuation stocks whose earnings
were unproven, but also contributed to the volatility, particularly among
large-capitalization stocks. The broad market fell during the reporting period,
with the Standard & Poor's 500 Index returning -3.60 percent and the
technology-heavy NASDAQ Index dropping 19.61 percent. In this turbulent
environment, smaller-cap, value-oriented stocks performed well, as they were
less affected by concerns about high valuations.

    We seek to maintain our "value with a catalyst" management strategy (see
sidebar) in all market environments, and this helped the fund's return during
the period. The fund returned 11.79 percent during the volatile six months ended
September 30, 2000 (Class A shares at net asset value; if the maximum sales
charge of 5.75 percent were included, the return would have been lower). Past
performance is no guarantee of future results. As a result of recent market
activity, current performance may vary from the figures shown. By comparison,
the Russell 2000(R) Value Index returned 9.43 percent during the same period.
This broad-based index measures the performance of those Russell 2000(R)
companies with lower price-to-book ratios and lower forecasted growth values.
This index is a statistical composite that doesn't include any commissions or
fees that would be paid by an investor purchasing the securities it represents.
Such costs would lower the performance of the index. It is not possible to
invest directly in an index. Please refer to the chart and footnotes on page 4
for additional fund performance results.

THE MANAGERS' INVESTMENT STRATEGY

WE REFER TO OUR INVESTMENT STRATEGY AS "VALUE WITH A CATALYST." WE SEARCH FOR
UNDERVALUED SMALL-CAP COMPANIES BY USING COMMON VALUATION MEASURES, SUCH AS
PRICE-TO-EARNINGS RATIO. FOR EACH STOCK WE CONSIDER FOR PURCHASE, WE SEARCH FOR
A SPARK (OR CATALYST)--SUCH AS A CHANGE IN MANAGEMENT, A NEW PRODUCT, OR NEW
INDUSTRY REGULATIONS--THAT MAY IGNITE THE COMPANY'S GROWTH PROSPECTS AND REVEAL
THE POTENTIAL VALUE HIDDEN IN THE CURRENT STOCK PRICE. WE MAY ALSO LOOK FOR
RISING EARNINGS EXPECTATIONS, WHICH WE BELIEVE CAN INDICATE THAT A CATALYST IS
PRESENT. IF A STOCK MEETS OUR CRITERIA, WE THEN CONSIDER IT FOR INVESTMENT. OUR
STOCK SELECTION PROCESS IS "BOTTOM-UP," THE FUND IS DIVERSIFIED ACROSS MULTIPLE
INDUSTRIES, AND WE NORMALLY REMAIN FULLY INVESTED IN MOST SITUATIONS.

Q   WHICH AREAS OF THE MARKET
    HELPED PERFORMANCE DURING THE REPORTING PERIOD?

A   Given the strong performance
of the financials sector during the reporting period, the fund's large position
in this sector benefited the performance of the fund. Individual holdings in the
fund's financials allocation included regional stocks, regional brokerage firms,
and real estate investment trusts.

    Despite the shakiness in the technology sector, several of the fund's
technology stocks migrated out of the small-cap arena into mid-size stocks
because of the stocks' market performance, which helped the fund capture gains
as the stocks were sold. Notably, International Rectifier, a power semiconductor
manufacturer, was sold from the fund's portfolio for a profit, as it no longer
met our investment discipline.

    Finally, some of the fund's health-care stocks performed well during the
period. Quest Diagnostics and Laboratory Corporation of America provide
outsourcing of clinical diagnostics from HMOs and other health-care providers.
Consolidation within the industry has helped these companies improve their
operating environments, and their stock prices appreciated as a result. Province
Healthcare had a strong record of acquiring and improving hospitals in rural
markets, and this stock also supported fund performance.

    Of course, not all stocks in the fund performed as favorably, nor is there
any guarantee that any of these stocks will continue to perform as well or will
be held by the fund in the future. For additional portfolio highlights, please
refer to page 5.

<PAGE>   101

Q   DID ANY STOCKS HURT THE FUND?

A   Most notably, two semiconductor
stocks hurt the performance of the fund during the reporting period: Lam
Research and S3. These stocks reacted poorly to Intel's announcement of a
revenue shortfall in September, as investors subsequently fled the industry
given concerns over sales growth expectations. Also, Georgia Gulf, a chemical
company, was hurt by inventory and margin issues with its polyvinyl chloride
(PVC) business during the period.

Q   WHAT DO YOU SEE AHEAD FOR
    THE FUND FOR THE UPCOMING SIX MONTHS?

A   Small-cap value stocks continue
to be attractively priced relative to the broad stock market. In this
environment, we will maintain our philosophy of seeking small-cap value
companies that have catalysts for change.

GLOSSARY OF TERMS

A HELPFUL GUIDE TO SOME OF THE COMMON TERMS YOU'RE LIKELY TO SEE IN THIS REPORT
AND OTHER FINANCIAL PUBLICATIONS.

BOTTOM-UP INVESTING: A management style that emphasizes the analysis of
individual stocks, rather than economic and market cycles.

CLASS A SHARES: Most Van Kampen mutual fund shares are typically divided into
three groupings, called Class A, Class B, and Class C shares, each with varying
fees and sales charges. Some Van Kampen mutual funds offer D shares as well.

MARKET CAPITALIZATION: The size of a company, as measured by the value of its
issued and outstanding stock.

NET ASSET VALUE (NAV): The value of a mutual fund share, calculated by deducting
a fund's liabilities from the total assets in its portfolio and dividing this
amount by the number of shares outstanding. The NAV does not include any initial
or contingent deferred sales charge.

PRICE-TO-EARNINGS (P/E) RATIO: Shows the "multiple" of earnings at which a stock
is selling. The P/E ratio is calculated by dividing a stock's current price by
its current earnings per share. A high multiple means that investors are
optimistic about future growth and have bid up the stock's price.

VALUATION: The estimated or determined worth of a stock, based on financial
measures such as the stock's current price relative to earnings, revenue, book
value, and cash flow.

VALUE INVESTING: A strategy that seeks to identify stocks that are sound
investments but are temporarily out of favor in the marketplace. As a result,
the stocks trade at prices below what value investors believe the stocks are
actually worth.

VOLATILITY: A measure of the fluctuation in the market price of a security. A
security that is volatile has frequent and large swings in price.

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Small Cap Value Fund (the "Fund") is organized as a series of Van
Kampen Equity Trust (the "Trust"), a Delaware business trust, and is registered
as a diversified open-end investment management company under the Investment
Company Act of 1940, as amended. The Fund's investment objective is to seek
capital appreciation by investing primarily in a diversified portfolio of equity
securities of small capitalization companies that the Fund's investment adviser
believes are undervalued. The Fund commenced investment operations on June 21,
1999 with three classes of common shares, Class A, Class B, and Class C shares.

    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

A. SECURITY VALUATION Investments in securities listed on a securities exchange
are valued at their sale price as of the close of such securities exchange.
Unlisted securities and listed securities for which the last sales price is not
available are valued at the mean of the bid and asked prices, or, if not
available, their fair value as determined in accordance with procedures
established in good faith by the Board of Trustees. Short-term securities with
remaining maturities of 60 days or less are valued at amortized cost, which
approximates market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.

    The Fund may invest in repurchase agreements which are short-term
investments whereby the Fund acquires ownership of a debt security and the
seller agrees to repurchase the security at a future time and specified price.
The Fund may invest independently in repurchase agreements, or transfer
uninvested cash balances into a pooled cash account along with other investment
companies advised by Van Kampen Investment Advisory Corp. (the "Adviser") or its
affiliates, the daily aggregate of which is invested in repurchase agreements.
Repurchase agreements are fully collateralized by the underlying debt security.
The Fund will make payment for such securities only upon physical delivery or
evidence of book entry transfer to the account of the custodian bank. The seller
is required to

NOTES TO

maintain the value of the underlying security at not less than the repurchase
proceeds due the Fund.

C. INCOME AND EXPENSE Dividend income is recorded on the ex-dividend date and
interest income is recorded on an accrual basis. Income and expenses of the Fund
are allocated on a pro rata basis to each class of shares, except for
distribution and service fees and transfer agency costs which are unique to each
class of shares.

D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.

    Net realized gains or losses may differ for financial and tax reporting
purposes as a result of post October 31 losses which are not recognized for tax
purposes until the first day of the following fiscal year.

    At September 30, 2000, for federal income tax purposes, cost of long- and
short-term investments is $14,160,956, the aggregate gross unrealized
appreciation is $2,334,508 and the aggregate gross unrealized depreciation is
$1,394,858, resulting in net unrealized appreciation on long- and short-term
investments of $939,650.

E. DISTRIBUTION OF INCOME AND GAINS The Fund declares and pays dividends
annually from net investment income. Net realized gains, if any, are distributed
annually. Distributions from net realized gains for book purposes may include
short-term capital gains and gains on option and futures transactions.

    Due to inherent differences in the recognition of certain expenses under
generally accepted accounting principals and federal income tax purposes, the
amount of distributed net investment income may differ for a particular period.
These differences are temporary in nature, but may result in book basis
distribution in excess of net investment income for certain periods.

F. EXPENSE REDUCTIONS During the six months ended September 30, 2000, the Fund's
custody fee was reduced by $453 as a result of credits earned on overnight cash
balances.

2. INVESTMENT ADVISORY AGREEMENT AND
OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, the Adviser will
provide facilities and investment advice to the Fund for an annual fee payable
monthly as follows:

<TABLE>
<CAPTION>
                  AVERAGE DAILY NET ASSETS                    % PER ANNUM
<S>                                                           <C>
First $500 million..........................................   .75 of 1%
Next $500 million...........................................   .70 of 1%
Over $1 billion.............................................   .65 of 1%
</TABLE>

    For the six months ended September 30, 2000, the Adviser voluntarily waived
$48,011 of its investment advisory fees and assumed $35,851 of the Fund's other
expenses. This waiver is voluntary in nature and can be discontinued at the
Adviser's discretion.

    For the six months ended September 30, 2000, the Fund recognized expenses of
approximately $200 representing legal services provided by Skadden, Arps, Slate,
Meagher & Flom (Illinois), counsel to the Fund, of which a trustee of the Fund
is an affiliated person. All of this expense has been assumed by Van Kampen.

    For the six months ended September 30, 2000, the Fund recognized expenses of
approximately $5,800 representing Van Kampen Funds Inc. or its affiliates'
(collectively "Van Kampen") cost of providing legal services to the Fund. All of
this expense has been assumed by Van Kampen.

    Van Kampen Investor Services Inc., an affiliate of the Adviser, serves as
the shareholder servicing agent for the Fund. For the six months ended September
30, 2000, the Fund recognized expenses of approximately $8,500. All of this
expense has been assumed by Van Kampen. Transfer agency fees are determined
through negotiations with the Fund's Board of Trustees and are based on
competitive market benchmarks.

    Certain officers and trustees of the Fund are also officers and directors of
Van Kampen. The Fund does not compensate its officers or trustees who are
officers of Van Kampen.

    The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation to a
later date. Benefits under the retirement plan are payable for a ten-year period
and are based upon each trustee's years of service to the Fund. The maximum
annual benefit per trustee under the plan is $2,500.

September 30, 2000 (Unaudited)

    For the six months ended September 30, 2000, Van Kampen, as Distributor for
the Fund, received commissions on sales of the Fund's Class A Shares of
approximately $6,100 and CDSC on redeemed shares of approximately $2,900. Sales
charges do not represent expenses of the Fund.

4. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $7,114,482 and $3,439,315, respectively.

5. DISTRIBUTION AND SERVICE PLANS

The Fund and its shareholders have adopted a distribution plan pursuant to Rule
12b-1 under the Investment Company Act of 1940, as amended and a service plan
(collectively the "Plans"). The Plans govern payments for the distribution of
the Fund's shares, ongoing shareholder services and maintenance of shareholder
accounts.

    Annual fees under the Plans of up to .25% of Class A net assets and 1.00%
each of Class B and Class C net assets are accrued daily. Included in these fees
for the six months ended September 30, 2000, are payments retained by Van Kampen
of approximately $28,200.

6. BORROWINGS

In accordance with its investment policies, the Fund may borrow from banks for
temporary purposes and is subject to certain other customary restrictions.
Effective November 30, 1999, the Fund, in conjunction with certain other funds
of Van Kampen, has entered in to a $650,000,000 committed line of credit
facility with a group of banks which expires on November 28, 2000, but is
renewable with the consent of the participating banks. Each fund is permitted to
utilize the facility in accordance with the restrictions of its prospectus. In
the event the demand for the credit facility meets or exceeds $650 million on a
complex-wide basis, each fund will be limited to its pro-rata percentage based
on the net assets of each participating fund. Interest on borrowings is charged
under the agreement at a rate of 0.50% above the federal funds rate per annum.
An annual commitment fee of 0.09% per annum is charged on the unused portion of
the credit facility, which each fund incurs based on its pro-rate percentage of
quarterly net assets. The Fund has not borrowed against the credit facility
during the period.

 OVERVIEW

LETTER TO SHAREHOLDERS
October 20, 2000

Dear Shareholder,

The first three quarters of 2000 proved to be especially volatile, with all of
the major markets declining in the spring and spending the following months
trying to recover. To manage one's portfolio during such unpredictable times
requires investment-management experience, and the following pages should give
you some insight into how we have performed in this difficult environment.

In this report, the portfolio managers will explain how your investment
performed during the reporting period and describe the strategies they used to
manage your fund during that span. The report will also show you how your
investment has performed over time. Helpful charts summarize the fund's largest
investments, and you can examine the complete portfolio to see all of your
fund's holdings as of the end of your fund's reporting period.

                  At Van Kampen, we place a high priority on providing you and
                  your financial advisor with the information you need to help
                  you monitor your investments during all types of markets. With
                  nearly four generations of investment-management experience,
                  we've been around long enough to understand that by investing
with Van Kampen you're entrusting us with much more than your money. Your
investments may help make it possible to afford your next house, keep up with
rising college costs, or enjoy a comfortable retirement.

No matter what your reasons for investing, we're thankful that you've chosen to
place your investments with Van Kampen. We will continue to apply our
generations of money-management experience to helping you pursue life's true
wealth.

Sincerely,

[SIG]
Richard F. Powers, III
President and CEO
Van Kampen Investments

ECONOMIC SNAPSHOT

ECONOMIC GROWTH
ECONOMIC GROWTH WAS STRONG DURING THE REPORTING PERIOD, UNDERPINNED BY LOW
UNEMPLOYMENT AND RISING PRODUCTIVITY, YET THERE WERE SIGNS THAT A HEALTHY
SLOWDOWN WAS UNDERWAY. GROSS DOMESTIC PRODUCT, THE PRIMARY MEASURE OF ECONOMIC
GROWTH, INCREASED AT A 2.7 PERCENT ANNUALIZED RATE FOR THE THIRD QUARTER OF
2000. FOLLOWING MILD FIRST- AND SECOND-QUARTER DATA, THIS THIRD-QUARTER FIGURE
OFFERS FURTHER EVIDENCE THAT GROWTH MIGHT BE SETTLING BACK TO A MORE MODERATE
AND SUSTAINABLE PACE THAN ITS RAPID RATE IN LATE 1999.

CONSUMER SPENDING AND EMPLOYMENT
CONCERNS ABOUT INFLATION REMAINED AT BAY DUE IN PART TO A GRADUAL SLOWDOWN IN
CONSUMER SPENDING. RISING INTEREST RATES, HIGHER ENERGY COSTS, AND A
DISAPPOINTING STOCK MARKET BEGAN TO TEMPER RETAIL SALES, WHICH LEVELED OFF FROM
THE BLISTERING PACE OF LATE 1999 AND EARLY 2000. AND WHILE CONSUMER SPENDING WAS
BRISK, THE OVERALL TREND HAS BEEN DOWNWARD THIS YEAR.

THE JOBLESS RATE CONTINUED TO BE EXTREMELY LOW BY HISTORICAL STANDARDS, BUT
RECENT CUTS IN MANUFACTURING PAYROLLS SUPPORT THE POPULAR BELIEF THAT THE
ECONOMY IS MODERATING. ALTHOUGH EMPLOYER COSTS SUCH AS WAGES AND BENEFITS WERE
RISING AT THE END OF 1999 AND IN THE BEGINNING OF 2000, OVER THE PAST SIX MONTHS
THE EMPLOYMENT COST INDEX HAS SHOWN MARKED DECELERATION, WHICH SHOULD HELP EASE
INFLATION CONCERNS.

INTEREST RATES AND INFLATION
THE FEDERAL RESERVE BOARD (THE FED) RAISED INTEREST RATES FOUR TIMES DURING THE
LAST 12 MONTHS IN AN EFFORT TO WARD OFF INFLATION BY CURBING ECONOMIC GROWTH.
OVER THE SAME PERIOD, THE CONSUMER PRICE INDEX ROSE 3.5 PERCENT, WHICH INDICATED
THAT INFLATION GENERALLY REMAINS UNDER CONTROL.

THE FED HAS ACKNOWLEDGED THE RISK OF RISING INFLATION AND WILL STAY ON GUARD, AS
RISING ENERGY COSTS AND LOW UNEMPLOYMENT THREATEN TO PROPEL THIS FIGURE UPWARD
IN THE COMING MONTHS. AS LONG AS INFLATION IS CONTAINED AND THE PACE OF ECONOMIC
GROWTH REMAINS FAVORABLE, THE FED IS LIKELY TO HOLD INTEREST RATES STEADY IN THE
SHORT TERM, WHICH COULD HELP STABILIZE THE STOCK AND BOND MARKETS.

SENIOR PORTFOLIO MANAGER GARY LEWIS, WHO HAS MANAGED THE FUND SINCE INCEPTION
AND HAS WORKED IN THE INVESTMENT INDUSTRY SINCE 1979, AND BY SENIOR PORTFOLIO
MANAGER JANET LUBY, WHO HAS ALSO MANAGED THE FUND SINCE INCEPTION AND HAS WORKED
IN THE INVESTMENT INDUSTRY SINCE 1989. THEY ARE JOINED BY SENIOR PORTFOLIO
MANAGERS DUDLEY BRICKHOUSE AND DAVID WALKER AND PORTFOLIO MANAGER MATTHEW HART.
THE FOLLOWING DISCUSSION REFLECTS THEIR VIEWS ON THE FUND'S PERFORMANCE.

Q   IN LIGHT OF THE MARKET CONDITIONS
    YOU'VE ENCOUNTERED THUS FAR, HOW WOULD YOU DESCRIBE THE FUND'S PERFORMANCE
    IN ITS FIRST THREE MONTHS OF OPERATIONS?

A   We believe the fund is off to a
good start, having achieved a total return of 4.50 percent for the period since
its inception (June 26, 2000, through September 30, 2000; Class A shares at net
asset value; if the maximum sales charge of 5.75 percent were included, the
return would have been lower). Past performance is no guarantee of future
results, and due to recent market activity, fund performance may vary from the
figure shown. Please refer to the chart and footnotes on page 4 for additional
portfolio performance results.

    This compares favorably to the performance of the Standard & Poor's 500
Index, which declined by 1.00 percent over the same period. The S&P 500 Index,
an unmanaged, capitalization-weighted measure of 500 stocks, is a statistical
composite that does not include any commissions or sales charges that would be
paid by an investor purchasing the securities it represents. Such costs would
lower the performance of the index. It is not possible to invest directly in an
index. Past performance is no guarantee of future results.

    The stock market has been trying to shake off the effects of the sharp
decline that occurred earlier this year, particularly in April and May. Some
stocks have rebounded nicely, but what

                                        6
<PAGE>   130

we've seen is a narrow market. That is, only a select group of stocks have
contributed significantly to the market's recovery.

    This type of market is precisely why the Van Kampen Select Growth Fund was
established earlier this year. When the performance of a few stocks is carrying
the performance of the market as a whole, good stock selection is a must. It is
imperative that portfolio managers not only invest in the right sectors, but
then they must also find the specific stocks within those sectors with the
potential to outperform. Because the fund is nondiversified, our approach is to
limit the fund's portfolio to fewer stocks than a typical diversified fund.
Specifically, we are looking for stocks with strong and improving fundamentals
accompanied by rising earnings expectations and rising valuations.

Q   WHAT WERE SOME OF THE
    CHALLENGES YOU FACED IN MANAGING THE FUND?

A   Even though the fund was
launched in June when the market was trying to recover from the declines of
April and May, we were not overly concerned with the timing of the fund's
inception. We seek capital appreciation over the long term.

    An important factor in the market's performance since the fund's inception
has been the Federal Reserve Board's push to control the growth of the economy
and keep inflation in check. Concerned that brisk economic growth would ignite
inflation, the Fed raised key short-term interest rates four times over the past
year, with the last increase in May 2000. Many investors worried that rising
interest rates would slow the economy, dampen business investment and consumer
spending, and put pressure on corporate earnings.

    These fears hit companies in the technology sector especially hard. Investor
concern over any real or perceived slowdown resulted in harsh reactions to
stocks considered to be the most vulnerable to an economic slowdown.

    Stock prices have been flat since then, although continued market volatility
suggests investors are struggling to assess the impact of interest rates, higher
commodities prices, political uncertainty, and other factors. Corporate earnings
are once again in the spotlight, and investors are on the lookout for companies
with more visible, more reliable earnings prospects.

Q   WHAT ARE SOME OF THE RISKS OF
    YOUR INVESTMENT STRATEGY?

A   The primary concern with this
approach is that the fund's assets are focused in a relatively small number of
issues--25 stocks as of September 30--which accentuates each stock's
contribution to the portfolio's overall performance. Because the fund is
nondiversified, it can take sizable positions in each individual stock. That
means both the potential gains and the potential losses are magnified.

    This underscores the need for thorough and insightful research. Our stock
selection process begins with a search for stocks that we believe are likely to
sustain their earnings momentum, as evidenced by rising

                                        7
<PAGE>   131

earnings expectations and rising valuations. Then we generally try to visit with
key executives to help us identify their strengths and their depth of experience
and to discuss and evaluate their business model.

Q   IN WHAT AREAS OF THE MARKET
    DID THE FUND INVEST DURING THE PERIOD?

A   As of September 30, slightly more
than half of the fund's net assets were invested in technology stocks,
accounting for seven of the fund's top 10 holdings. This is a market sector
that, in our opinion, continued to hold promise as demand for "anywhere to
anywhere" connectivity drives the need for bandwidth to accommodate the
exploding growth of data and Internet traffic.

    Financial stocks were the second largest allocation in the portfolio,
representing 18.5 percent of net assets. We believe this sector offered a number
of opportunities, particularly in the brokerage, insurance, and specialty
finance arenas, as these companies have benefited from an improving
interest-rate environment and a stronger fundamental outlook.

    Energy stocks represented 11.1 percent of net assets. Strong demand
accompanied by limited supply contributed to strength in commodity prices and
the associated increase in earnings expectations. Power capacity shortages
helped independent power producers, such as Calpine Corporation, which was one
of the fund's top 10 holdings.

Q   WHAT ARE SOME OF THE STOCKS
    THAT PERFORMED WELL DURING THE PERIOD FOR THE FUND?

A   Check Point Software, Ciena
Corporation, Siebel Systems, and Juniper Networks were among the fund's
top-performing technology stocks. All of these firms have gained from the rapid
growth in Internet traffic and the related need for bandwidth, security, and
software.

    In the financial sector, we have seen strong performance from Lehman
Brothers Holdings, which benefited from strength in its core trading and
underwriting business, and from Marsh & McLennan, an insurance firm with good
earnings and an improving pricing structure.

    In health care, the stock of UnitedHealth Group, a large health maintenance
organization, has been buoyed by the company's ability to increase prices while
keeping costs in check.

    Of course, not all of the stocks in the fund performed as favorably, nor is
there any guarantee that any of these stocks will continue to perform or will be
held by the fund in the future. For additional fund highlights, please refer to
page 5.

Q   WHICH STOCKS PERFORMED
    BELOW YOUR EXPECTATIONS DURING THE PERIOD?

A   We were disappointed by the
performance of Kohl's Corporation, an operator of a department store chain. Even
though their fundamentals were

                                        8
<PAGE>   132

solid and their management team was quite strong, their stock has been punished
by investor fears of a weakening retail environment.

    Also, earnings disappointments hurt some of the historically strong
technology stocks. This dragged down some of the other technology issues held by
the fund during the reporting period, such as Micron Technology, a semiconductor
manufacturer.

Q   WHAT IS YOUR OUTLOOK FOR
    THE MARKET?

A   In general, we're still quite bullish.
The leadership we have seen from the financials and the utilities bodes well for
the market. Also, historically, the fourth quarter of the year has been strong
for technology stocks, as companies accelerate spending to exhaust their budgets
for computer equipment, supplies, and services.

    Nevertheless, the fourth quarter of 2000 started with profit warnings from
traditional technology leaders like Apple, Dell, and Intel, which triggered a
fairly severe sell-off. We expect to get the bad news out of the way early in
the quarter and move into a more constructive environment over the rest of the
year.

    In the short term, investors will likely continue to focus on corporate
earnings, so we expect to see persistent volatility in stock prices as the
market reacts to various earnings announcements. The market appears to be
anticipating no further rate increases until next year, as the economy appears
to be growing more slowly with inflation under control. Barring an unforeseen
external shock, we remain optimistic with regard to the overall environment for
stocks.

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Select Growth Fund (the "Fund") is organized as a series of Van
Kampen Equity Trust (the "Trust"), a Delaware business trust, and is registered
as a non-diversified open-end investment management company under the Investment
Company Act of 1940, as amended. The Fund's investment objective is to seek
capital appreciation by investing primarily in a non-diversified portfolio of
common stocks and other equity securities of growth companies considered by the
Fund's adviser to be unusually attractive growth opportunities on an individual
company basis. The Fund commenced investment operations on June 26, 2000 with
three classes of common shares: Class A, Class B, and Class C.

    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

A. SECURITY VALUATION Investments in securities listed on a securities exchange
are valued at their sale price as of the close of such securities exchange.
Unlisted securities and listed securities for which the last sales price is not
available are valued at the mean of the bid and asked prices, or, if not
available, their fair value as determined in accordance with procedures
established in good faith by the Board of Trustees. Short-term securities with
remaining maturities of 60 days or less are valued at amortized cost, which
approximates market value.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.

    The Fund may invest in repurchase agreements which are short-term
investments whereby the Fund acquires ownership of a debt security and the
seller agrees to repurchase the security at a future time and specified price.
The Fund may invest independently in repurchase agreements, or transfer
uninvested cash balances into a pooled cash account along with other investment
companies advised by Van Kampen Investment Advisory Corp. (the "Adviser") or its
affiliates, the daily aggregate of which is invested in repurchase agreements.
Repurchase agreements are fully collateralized by the underlying debt security.
The Fund will make payment for such securities only upon physical delivery or
evidence of book entry transfer to the account of the custodian bank. The seller
is required to

NOTES TO

maintain the value of the underlying security at not less than the repurchase
proceeds due the Fund.

C. INCOME AND EXPENSE Interest income is recorded on an accrual basis and
dividend income is recorded on the ex-dividend date. Income and expenses of the
Fund are allocated on a pro rata basis to each class of shares, except for
distribution and service fees and transfer agency costs which are unique to each
class of shares.

D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.

    At September 30, 2000, for federal income tax purposes, cost of long- and
short-term investments is $1,129,193,498, the aggregate gross unrealized
appreciation is $154,039,457 and the aggregate gross unrealized depreciation is
$12,524,267, resulting in net unrealized appreciation on long- and short-term
investments of $141,515,190.

E. DISTRIBUTION OF INCOME AND GAINS The Fund declares and pays dividends
annually from net investment income. Net realized gains, if any, are distributed
annually. Distributions from net realized gains for book purposes may include
short-term capital gains which are included as ordinary income for tax purposes.

2. INVESTMENT ADVISORY AGREEMENT AND
OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, the Adviser will
provide investment advice and facilities to the Fund for an annual fee payable
monthly as follows:

trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation to a
later date. Benefits under the retirement plan are payable for a ten-year period
and are based upon each trustee's years of service to the Fund. The maximum
annual benefit per trustee under the plan is $2,500.
