 WHY THE NAME CHANGE?
 
 If you've been invested in any of these Portfolios
 for a while, you used to know them as the Schwab OneSource Portfolios. We
 recently changed their names to better reflect the active management of these
 Funds. In fact, the change was a result of feedback we received from you, our
 investors. We wanted to clearly communicate active portfolio management and
 eliminate any confusion regarding the Portfolios' relationship to Schwab's
 Mutual Fund OneSource-Registered Trademark- service.

A MESSAGE FROM THE CHAIRMAN
 
Dear Shareholder,
 
The U.S. stock market rallied strongly over most of the six-month period ended
April 30, 1998. So did many European markets. Despite investors' concerns about
Asia's financial crisis last autumn, economic conditions continued to provide a
solid underpinning for U.S. business activity. Once again, blue chips led the
rally, though many smaller-cap stocks posted very solid gains in absolute terms.
You'll find more insight about the overall market beginning on page 4.

                  As pleased as we are with the performance of our Funds during
                  this period, we want to be realistic. Over most of this
                  century, for example, the U.S. stock market has returned an
                  average of 11% to 12% PER YEAR, not per quarter. We encourage
investors to keep that in mind should the market revert to its historical
pattern of more-moderate performance.
 
Our philosophy has always been that REGULAR INVESTING, regardless of short-term
market trends, is the best strategy over the long term. By investing in one of
our SchwabFunds-Registered Trademark-, you've already taken an important step in
building a portfolio that can help you meet your future goals. On the following
pages, we outline several ways to help ensure that you reach those goals by
establishing--or maintaining--an ongoing investment program.
 
NEW INVESTMENT OPPORTUNITIES TO CONSIDER
We are proud to introduce a new addition to our family of Funds: THE SCHWAB
MARKETTRACK ALL EQUITY PORTFOLIO. (SCHWAB MARKETTRACK PORTFOLIOS-TM- is the new
name of Schwab's Asset Director-Registered Trademark- Funds.) This Portfolio,
which targets 100% equity investing, can provide you with diversified exposure
to three different areas of the stock market: U.S. large-company, U.S.
small-company and international stocks. We also offer three other MarketTrack
Portfolios: Growth, Balanced and Conservative. Each invests a different
proportion of its assets in bonds and cash in addition to stocks.
 
For additional information and a free prospectus on the Schwab MarketTrack
Portfolios or any of our SchwabFunds, please call us toll free at
1-800-435-4000. Each prospectus contains more-complete information on our Funds,
including their fees and expenses; please read the prospectus carefully before
you invest.
 
The support of investors like you has helped Charles Schwab Investment
Management, Inc. (CSIM) become one of the largest and fastest-growing mutual
fund families in the nation. CSIM now manages more than $63 billion in assets on
behalf of more than 3.3 million SchwabFunds shareholders. We offer a full
spectrum of 34 mutual funds for investors with varying financial situations and
goals.
 
Once again, thank you for your investment in SchwabFunds. We continue to do
everything we can to warrant the trust you have placed in us.
 
Sincerely,
 
/s/ Charles R. Schwab

WHAT EVERY INVESTOR SHOULD KNOW
 
WHY ASSET ALLOCATION MATTERS
 
As most investors know, one of the most compelling reasons to invest in a mutual
fund is diversification. By allocating your assets across many different
securities, a fund helps reduce the risk that you might otherwise encounter by
owning just a few stocks or bonds.
 
Don't forget, however, that diversification across your portfolio can be just as
important as diversification within one of the mutual funds you own. As you
probably know, stocks have historically offered much higher returns over the
long term than bonds, cash or other asset classes, but those returns have come
at the price of higher volatility. To help mitigate some of that risk, many
investors often include at least some bonds and cash in their portfolios. They
also diversify their equity exposure across different market segments--such as
U.S. large-cap, U.S. small-cap and international, which have tended to move with
less than perfect correlation over time. In short, allocating assets across
market segments may help reduce your overall portfolio risk.
 
 THE SCHWAB APPROACH
 TO INVESTING
 
  - START WITH THE BASICS FOR
     LONG-TERM INVESTING.
 
  - GET STARTED NOW!
 
  - KNOW YOURSELF.
 
  - INVEST IN THE STOCK MARKET
     FOR GROWTH.
 
  - TAKE A LONG-TERM VIEW.
 
  - BUILD A DIVERSIFIED PORTFOLIO.
 
  - CONSIDER BONDS AND CASH FOR
     DIVERSIFICATION AND INCOME.
 
  - MINIMIZE YOUR EXPENSES.
 
  - STAY ON TRACK.
 
  - BECOME A LIFELONG INVESTOR.
 
Asset allocation can sound simple in theory, but most individual investors find
it difficult to put into practice. Few of us have the time or resources to keep
track of the market and maintain balanced exposure across asset classes. For
example, if stocks perform especially well during a certain period, your equity
exposure may grow to take up a bigger share of your portfolio than you're
comfortable with.
 
That's why it makes a lot of sense to "automate" your asset allocation
decisions. Schwab has developed a broad spectrum of portfolio solutions that
make it convenient for you to apply this time-tested investment strategy. If
you'd like more information, please call us at 1-800-435-4000, access our Web
site at WWW.SCHWAB.COM/SCHWABFUNDS or visit the Schwab branch nearest you.
 
REGULAR-INVESTING STRATEGIES
 
Another way to help dampen the effects of short-term market volatility is to
invest the same amount of money on a regular basis. With this investment
strategy, known as DOLLAR-COST AVERAGING, you automatically buy more shares when
stock or bond prices are low and fewer when they're high.
 
A hypothetical example can help illustrate this concept. Let's say you invest
$400 on a monthly basis in a single mutual fund, as shown in the illustration
below. Because of fluctuating prices, your per-share purchase price varies
monthly. A simple average of your five purchase prices would yield $8.20 per
share; however, your AVERAGE COST BASIS (your total investment divided by the
number of shares actually purchased) would be significantly lower--by more than
$0.50 per share. The net result in this example is that your average cost per
share is reduced and you'd have purchased more shares than you would have had
you paid the average share price over the five-month period.

(Of course, in this example, hindsight shows you that your best move would have
been to invest your entire $2,000 in Month 3 when the share price was at a low
of $5--but it's unlikely that you would have been able to predict that.)
 
In addition to reducing your per-share costs over time, dollar-cost averaging
provides you another benefit: the discipline of investing regularly. You're more
likely to maintain a regular investment plan if it's automatic: not only do you
not have to even think about it, but you minimize any propensity to skip an
investment in favor of some other expenditure. To encourage this discipline,
Schwab offers you two convenient, no-cost ways to begin or maintain a program of
regular investing:
 
Schwab's AUTOMATIC INVESTMENT PLAN (AIP) allows you to automatically
purchase--on a regular basis--additional shares in mutual funds that you already
own. For amounts as little as $100 per month, you can use the cash or sweep
shares of your existing Schwab Money Fund,(1) or you can enroll in Schwab's free
MONEYLINK TRANSFER SERVICE to automatically transfer money to your Schwab
account.
 
With MONEYLINK TRANSFER SERVICE-Registered Trademark-, you can arrange to
regularly and automatically transfer $50 or more from your bank account, payroll
or government check into your Schwab account. It's a great way to build your
investment over time.(2)
 
Please be aware that these programs--and dollar-cost averaging in general--do
not ensure a profit or protect against a loss, and investors should know that
markets fall as well as rise. Over the long term, however, dollar-cost averaging
may help to smooth out volatility caused by short-term market trends. For more
information about these programs, please call us at 1-800-435-4000.

At the time of this writing, THE U.S. ECONOMY APPEARS POISED FOR CONTINUED
GROWTH, further extending the current economic expansion that began in 1991.
Many economists expect Asia's economic problems to reduce 1998 U.S. GDP growth
by only a relatively minor 0.25 to 1.0 percentage point.
 
PRIOR TO THE FOURTH-QUARTER ONSET OF THE "ASIAN FLU," the U.S. economy's
strength and tight labor markets led investors to speculate about whether wage
and price inflation were accelerating. Some investors also believed that the
Federal Reserve was on the verge of raising interest rates to head off a
potential acceleration in both wage and price inflation. As Federal Reserve
Chairman Alan Greenspan said in his February congressional testimony, "The key
question going forward is whether the restraint building from the turmoil in
Asia will be sufficient to check inflationary tendencies that might otherwise
result from the strength of domestic spending and tightening labor markets." At
the moment, many economists believe that Federal Reserve policy-makers are now
more inclined to raise interest rates than they have been in the past, but are
refraining from doing so because inflation remains tame and Asia's continuing
problems may dampen both global and domestic growth.
 
UNEMPLOYMENT
 
JOB GROWTH IN THE UNITED STATES HAS REMAINED ROBUST. In fact, the U.S.
unemployment rate reached 4.3% in April--the lowest level in 28 years.

THE CPI ROSE just 1.4% over the year ended April 1998--the lowest rate of
increase since 1986. Its core rate (which excludes the more volatile food and
energy components) rose 2.1%--the lowest rate of increase since 1965. Investors
were somewhat more concerned about the ECI, and its wages and salaries component
in particular. That segment of the ECI increased 3.7% during the year ended
April 1998.
 
EVEN THOUGH CURRENT LEVELS OF INFLATION ARE VERY LOW, Federal Reserve
policy-makers have indicated that they believe the risk of inflation is
increasing, and they are poised to act preemptively by raising interest rates if
they believe that is necessary. The Federal Reserve did raise interest rates in
March 1997, increasing the federal funds rate by 0.25 percentage point to 5.5%.
By the end of April, many economists believed that Federal Reserve policy-makers
were once again inclined to raise interest rates, but there was a lack of
consensus about when the Federal Reserve would raise interest rates, if in fact
it would, and by how much.
 
TOTAL-RETURN PERFORMANCE
 
MOST U.S. STOCKS posted strong total returns from November 1, 1997, through
April 30, 1998. Large-caps continued to outperform small-caps, as reflected in
the 22.5% return of the S&P 500-Registered Trademark- Index versus the 13.4%
return of the Schwab Small-Cap Index-Registered Trademark- over the period.
Amazingly, the S&P 500 Index posted its thirteenth consecutive quarterly gain
during the first quarter of 1998 and posted an incredible return of 41% for the
12-month period ended April 1998.
 
INTERNATIONAL STOCKS, as represented by the Schwab International
Index-Registered Trademark-, gained 15.2% over the six-month period, primarily
on the strength of European markets.
 
FIXED-INCOME RETURNS were more in line with long-term expectations during the
reporting period. Bond returns, as represented by the Lehman Brothers Aggregate
Bond Index, were 3.6% over the six-month reporting period.

TOTAL RETURN ASSUMES REINVESTMENT OF ALL DIVIDENDS AND CAPITAL GAINS
DISTRIBUTIONS. PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. The indices
are intended to represent the returns of specific market sectors during the
funds' six-month reporting period and do not reflect the performance of any
fund. Indices are unmanaged and, unlike a fund, do not reflect the payment of
advisory fees and other expenses associated with an investment in a fund.
Investors cannot invest in an index directly.
 
S&P 500 PRICE/EARNINGS RATIO
 
THE PRICE/EARNINGS RATIO for the S&P 500 Index reached its highest value ever
during the reporting period: It stood at 26.5 at the close of the reporting
period, well above its 30-year average of 14.8. The price/earnings ratio, also
known as a multiple, is the price of a stock divided by its earnings per share
and generally indicates how much investors are willing to pay for a company's
earning potential.
 
Based on other traditional market valuation measures such as the price-to-book
value ratio or dividend yield, the U.S. stock market, as measured by the S&P 500
Index, also reached historic highs during the reporting period.

THE PRIMARY FACTORS DRIVING THESE HISTORIC EQUITY VALUATIONS have been low
inflation, low interest rates, healthy corporate earnings expectations, a
decline in the amount of equities outstanding (due to merger activity and share
buybacks) and high levels of consumer optimism. Changes in any of these factors
could have a negative impact on these lofty market valuations.
 
INTERNATIONAL PERFORMANCE
 
MOST EUROPEAN EQUITY MARKETS were strong during the six months ended April 30,
1998, with the highest returns in Spain, Italy, Finland and Ireland. In
contrast, many Asian markets declined sharply over the period; the weakest were
Malaysia, New Zealand, Hong Kong and Japan.

THE MSCI-EAFE-REGISTERED TRADEMARK- INDEX gained 15.4% in U.S. dollar terms
(excluding reinvested dividends) during the six-month reporting period. In
local-currency terms, it gained 20.3%, reflecting the relative strength of the
U.S. dollar versus most foreign currencies during the period.

(1)The Investment Manager and Schwab waived a portion of their fees during the
   reporting period and have guaranteed through at least 2/28/99 that total
   operating expenses will not exceed 0.50%. Without fee waivers and guarantees,
   as of 4/30/98, the six-month, one-year and average annual since-inception
   total returns would have been 12.18%, 28.43% and 20.45%, respectively, for
   the Growth Portfolio and 9.63%, 23.27% and 16.79%, respectively, for the
   Balanced Portfolio. As of 3/31/98, the six-month, one-year and average annual
   since-inception total returns would have been 7.82%, 30.20% and 21.21%,
   respectively, for the Growth Portfolio and 6.88%, 24.95% and 17.57%,
   respectively, for the Balanced Portfolio.
 
This graph compares the growth of a hypothetical $10,000 investment in the
Schwab MarketManager Growth and Balanced Portfolios, made at their inception,
with similar investments in the S&P 500-Registered Trademark- Index and the
Lehman Brothers Aggregate Bond Index. A detailed analysis of the respective
performance of the Portfolios and the indices is provided in the QUESTIONS TO
THE PORTFOLIO MANAGEMENT TEAM section later in this report.
 
THIS INFORMATION IS HISTORICAL AND DOES NOT REPRESENT FUTURE RESULTS. TOTAL
RETURNS ASSUME REINVESTMENT OF ALL DIVIDENDS AND CAPITAL GAINS DISTRIBUTIONS.
PRINCIPAL VALUE AND INVESTMENT RETURNS WILL FLUCTUATE, SO AN INVESTOR'S SHARES,
WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. Indices are
unmanaged and do not reflect advisory fees and other expenses associated with an
investment in the Portfolios. Investors cannot invest in an index directly.

PORTFOLIO SUMMARY
 
Schwab MarketManager Growth Portfolio seeks capital growth with less volatility
than a portfolio composed entirely of stock funds. The Balanced Portfolio seeks
capital growth and income with less volatility than the Growth Portfolio. The
allocations of the Funds' portfolios will vary as the Portfolio Manager adjusts
their respective asset mixes based on changing market conditions. Of the two
Portfolios, the Growth Portfolio offers the greatest potential for return and
risk due to its larger target allocation to equity funds.

SCHWAB MARKETMANAGER GROWTH AND BALANCED PORTFOLIOS:
PORTFOLIO DISCUSSION
 
QUESTIONS TO THE
PORTFOLIO MANAGEMENT TEAM
 
Q. HOW DID THE PORTFOLIOS PERFORM DURING THE
REPORTING PERIOD?
 
A. The Growth and Balanced Portfolios produced total returns of 12.60% and
10.07%, respectively, for the six-month period ended April 30, 1998. Bear in
mind that the target equity allocations are 80% for the Growth Portfolio and 60%
for the Balanced Portfolio. Given that equities generally outperformed bonds
during the reporting period, the relative performances of the two Portfolios and
the indices remain consistent with our long-term expectations. There may be
future short-term periods, however, in which the results may be reversed.
 
Q. WHICH ASSET CLASSES PERFORMED WELL FOR THE PORTFOLIOS?
 
A. During the six-month period ended April 30, 1998, U.S. large-cap mutual funds
outperformed U.S. small-cap funds. International mutual funds, especially those
heavily invested in Europe, also did well during the period.
 
Q. WHICH UNDERLYING FUNDS PERFORMED PARTICULARLY WELL FOR THE PORTFOLIOS?
 
A. American Century--Twentieth Century International Discovery, an international
small-company fund, delivered extremely strong performance over the reporting
period due to the manager's investment style, which captured the strong returns
of the European stock market. (The fund constituted 1.05% of the Balanced
Portfolio and 1.50% of the Growth Portfolio as of the end of the reporting
period.) Domestically, the strong performance of the White Oak Growth Stock Fund
(representing 1.97% of the Balanced Portfolio and 3.12% of the Growth Portfolio
at the end of the period) was the result of its exposure to technology and drug
companies. Even the relative underperformance of small-cap stocks did not hold
back RIMCo Monument SmallCap Equity Fund (representing 0.63% of the Balanced
Portfolio and 0.75% of the Growth Portfolio), which has performed very well
since the Portfolios purchased it.
 
Q. HOW DID THE PORTFOLIOS' STRATEGIES CHANGE DURING THE REPORTING PERIOD?
RELATIVE TO THEIR NEUTRAL TARGETS, HOW WERE THE PORTFOLIOS POSITIONED AT THE
CLOSE OF THE REPORTING PERIOD?
 
A. The Portfolios' overall asset allocation strategies did not change
significantly; they remained close to their targets throughout the period.
Within the U.S. equity category, we continued to favor large-cap funds over
small-cap funds, due to the relatively strong performance of large-cap stocks
and the continuation of favorable macroeconomic conditions. Internationally, the
Portfolios remained focused on Europe, a strategy we had put in place before the
Asian crisis transpired last fall.
 
The Portfolios ended the reporting period near a neutral allocation (see the
actual vs. target mixes in neutral markets in the table on page 9 for the Growth
Portfolio and page 10 for the Balanced Portfolio). Within the U.S. equity
categories, however, the Portfolios remained slightly underweighted in small-cap
funds in favor of large-cap funds. In fixed income, the Portfolios were slightly
underweighted in intermediate-term bond funds, whereas cash was near a neutral
weighting.

</TABLE>
 
Q. CAN YOU DISCUSS A COUPLE OF NEW FUNDS THAT WERE PURCHASED DURING THE PERIOD?
 
A. Two funds we recently purchased for both Portfolios were the RIMCo Monument
SmallCap Equity Fund and the Excelsior Value and Restructuring Fund.
 
We purchased the RIMCo fund as part of our small-cap allocation (it represented
0.63% of the Balanced Portfolio and 0.75% of the Growth Portfolio at the end of
the reporting period). This fund has an excellent performance record. Its
manager, Philip Tasho, has also demonstrated an ability to capture upside return
while still protecting shareholders on a relative basis in down markets. Tasho
uses both valuation and price momentum screens to select stocks. RIMCo and Tasho
also manage money for large institutions and have a very good long-term
performance record.
 
The Excelsior Value and Restructuring Fund is a large-cap, value-oriented mutual
fund (it represented 5.49% of the Balanced Portfolio and 5.40% of the Growth
Portfolio at the end of the reporting period). The fund's manager, David
Williams, looks for companies that are undergoing structural change and
therefore have the potential for appreciation if the company's management can
redirect the firm's assets and expertise to more-productive ends. The fund's
long-term performance has been excellent, and we believe its potential ability
to capture returns even in growth-oriented markets can enable it to perform well
in a variety of environments.
 
                                                                              13

PORTFOLIO DISCUSSION (continued)
 
Q. WHAT ARE THE BENEFITS OF INCLUDING BONDS AND CASH IN AN INVESTMENT PORTFOLIO?
 
A. Adding bonds and cash equivalents to a stock-oriented portfolio can help
reduce its overall risk. The chart at the right displays the high, low and
average annual returns from 1970 to 1997 for five hypothetical portfolios
representing the returns of stocks and bonds measured by indices.(1) As the
chart demonstrates, adding bonds to a stock-heavy portfolio would have reduced
its risk while still producing competitive returns.
 
A hypothetical portfolio with 60% of its assets in stocks and the remaining 40%
in bonds, for example, would have achieved an average annual return of
11.65%--roughly 1.3 percentage points less than the 12.97% return of the
all-stock portfolio--and with significantly less volatility. The lowest annual
return-- a loss of 13.61%--of the portfolio that had 40% in bonds and 60% in
stocks would have been about half the 26.47% loss in the all-stock portfolio.
This hypothetical example is for illustrative purposes only, and, of course,
past performance does not guarantee future results.
 
(1)The hypothetical returns are all weighted averages and assume reinvestment of
   dividends. Stocks are represented by the S&P 500 Index, and bonds are
   represented by the Ibbotson Intermediate U.S. Government Bond Index. Indices
   are unmanaged, do not incur costs and expenses and cannot be invested in
   directly. Portfolios were rebalanced annually. Returns represent historical
   performance of these indices and not performance of any specific investments.

SCHWAB MARKETMANAGER SMALL CAP PORTFOLIO:
PORTFOLIO DISCUSSION
 
QUESTIONS TO THE
PORTFOLIO MANAGEMENT TEAM
 
Q. HOW DID THE PORTFOLIO PERFORM DURING THE REPORTING PERIOD?
 
A. The Portfolio achieved a 9.09% total return for the six-month reporting
period. Although this performance was certainly respectable, U.S. small-cap
equity returns continued to lag those of the U.S. large-cap equity sector. The
Portfolio also underperformed its benchmark, the Russell 2000-Registered
Trademark- Index. However, the Portfolio slightly outperformed the average
small-cap fund, which returned 8.94% for the period.(1)
 
Q. HOW DID THE PORTFOLIO'S STRATEGY CHANGE DURING THE REPORTING PERIOD, AND HOW
WAS IT POSITIONED AT THE CLOSE OF THE PERIOD?
 
A. While keeping the Portfolio's bias toward the small-cap value discipline, we
have slightly increased its exposure to small-cap growth funds. This tactical
move was based on our belief that there were attractive small-cap growth
companies whose share prices declined sharply in 1997 as investors favored
small-cap value stocks. As a result, the performance gap between the Russell
2000 Value Index and the Russell 2000 Growth Index was the widest we had seen in
many years. Strategically, however, we continue to position the Portfolio with a
value bias, which we believe to be the prudent policy in the current market
cycle.
 
Q. CAN YOU SHARE A COUPLE OF EXAMPLES OF NEW HOLDINGS PURCHASED DURING THE
PERIOD, AND WHY?
 
A. We recently added the Accessor Small to Mid Cap Fund to the Portfolio (the
fund represented 2.99% of the Portfolio at the end of the reporting period).
This fund still has a relatively small asset base and is unfamiliar to most
investors, even though it has compiled a very strong record since its inception
in 1992. The fund's portfolio managers employ several quantitative screens to
find potentially attractive investments among mid- to small-cap U.S. stocks; in
addition to a company's earnings growth and stock valuations, they also consider
whether the firm's top executives have recently bought or sold a significant
number of shares in the company. That additional screen, which can indicate
whether the firm's management has a positive or negative outlook for the
company, is one of the things that sets the Accessor Small to Mid Cap Fund apart
from other quantitative funds. We are very comfortable with the fund's
subadvisor, Symphony Asset Management, and we strongly believe that its
investment model will help the fund outperform in the mid- to small-cap arena.
 
Another relatively new fund we purchased was the PBHG Small Cap Value Fund (the
fund represented 1.92% of the Portfolio at the end of the reporting period). Its
manager, Gary Haubold (who previously managed the MAS Small Cap Value Fund), has
adopted a thematic approach that identifies major secular growth trends and the
companies positioned to benefit, and then performs fundamental analysis. Haubold
overlays this strategy with a strong valuation discipline, paying particular
attention to a company's free cash flow and price/earnings multiples.
 
(1)Source: Morningstar, Inc. The Small-Fund category contains 393 funds with
   track records for the six-month period ended 4/30/98. These funds may or may
   not follow a tax-efficient strategy similar to that followed by the Schwab
   MarketManager Small Cap Portfolio. Also, although many mutual funds have
   multiple classes of shares, the category average includes only those funds
   that were classified by Morningstar as a distinct portfolio. This typically
   means that a fund's oldest class of shares was used.
 
                                                                              17

SCHWAB MARKETMANAGER SMALL CAP PORTFOLIO:
PORTFOLIO DISCUSSION (continued)
 
Q. GIVEN THE RECENT UNDERPERFORMANCE OF SMALL-CAP STOCKS, IS THERE STILL A
REASON TO INVEST IN THEM?
 
A. If history is any guide, yes. As the first of the graphs at the right
illustrates, the total returns of U.S. large-cap and small-cap stocks have been
fairly comparable over extended periods of time--such as from 1970 to 1997. As
the second graph illustrates, over the past 28 years small-cap stocks have
outperformed large-caps 14 times, over varying lengths of time. In the remaining
14 years, large-caps outperformed small-caps. There appears to be little, if
any, predictability to this seesaw effect. That's why it's wise for an investor
to consider diversifying his or her portfolio by holding both small- and
large-cap stocks. Small-cap stocks generally outperformed large-cap stocks from
1991 to 1993. Large-cap stocks were the clear winners from 1994 through 1997.
Although not readily apparent from viewing these graphs, small-cap stocks have
also exhibited a higher level of volatility over the period shown.

SCHWAB MARKETMANAGER INTERNATIONAL PORTFOLIO:
PORTFOLIO DISCUSSION
 
QUESTIONS TO THE
PORTFOLIO MANAGEMENT TEAM
 
Q. HOW DID THE PORTFOLIO PERFORM DURING THE REPORTING PERIOD?
 
A. The Portfolio achieved a 17.25% total return for the six-month reporting
period. As shown in the FUND PERFORMANCE section, the Portfolio's performance
was very favorable when compared with the average foreign fund and the
MSCI-EAFE-Registered Trademark- Index, outperforming the average foreign fund by
approximately 3% for both the six-month and one-year periods, and outperforming
the MSCI-EAFE Index by more than 6% on an inception-to-date basis.(1) The
Portfolio's performance was primarily a result of its ability to avoid the
landmines of the emerging markets, its underweighting in Japan and strong
performance by its top fund selections. As discussed in the MARKET OVERVIEW
section, however, international equity returns lagged those of the domestic
large-cap equity sector during the reporting period.
 
Q. WHAT IMPACT DID THE TURMOIL IN ASIA'S EMERGING MARKETS HAVE ON THE PORTFOLIO?
 
A. Even prior to the start of the reporting period, we had been concerned about
the deteriorating macro-economic environment in some of the emerging Asian
economies and had made a strategic allocation decision not to invest in the
region. In a several cases, we substantially reduced our investments, as we
believed the impact on the portfolio would be prolonged. As a result of this
strategic decision, the Fund was largely spared the unpleasant sharp falls in
these markets. There was, however, some minor exposure (approximately 3% in
aggregate) to the affected markets in a few of the underlying funds. We decided
to keep invested in most of these funds in spite of their exposure after
considering their overall performance and style.
 
Q. WHAT WAS THE PORTFOLIO'S EMERGING MARKETS EXPOSURE DURING THE REPORTING
PERIOD?
 
A. In the summer of 1997, prior to the onset of turmoil in Asia, the Portfolio
had emerging markets exposures to Latin America and eastern Europe totaling some
7% through two regional funds. Since that time, we made a tactical decision to
sell these funds as we felt the turmoil in Asia had the potential to spread to
other emerging markets. Although the Portfolio maintained a small, indirect
exposure to emerging markets as a result of holdings in underlying funds, it had
no direct emerging markets exposure during the reporting period.
 
Q. WHICH SECTORS OR REGIONS PERFORMED WELL FOR THE PORTFOLIO?
 
A. During the reporting period, developed European markets continued to be the
most consistent performers. Small-cap stocks in the core European countries and
investments in the peripheral European markets such as Turkey, Greece and
Portugal, as well as increased exposure to Latin America, also contributed to
the Portfolio's performance during the period.
 
(1)Source: Morningstar, Inc. The Foreign Fund category contains 271 funds with
   six-month track records and 259 funds with one-year track records, both as of
   4/30/98. Also, although many mutual funds have multiple classes of shares,
   the category average includes only those funds that were classified by
   Morningstar as a distinct portfolio. This typically means that a fund's
   oldest class of shares was used.
 
                                                                              21

SCHWAB MARKETMANAGER INTERNATIONAL PORTFOLIO:
PORTFOLIO DISCUSSION (continued)
 
Q. WHAT IMPACT DID CURRENCY EXCHANGE RATES HAVE ON THE PERFORMANCE OF
INTERNATIONAL EQUITIES AND THE PORTFOLIO?
 
A. In retrospect, complete currency hedging, which would protect against
changing values of foreign currencies relative to the U.S. dollar, would have
been the right strategy for the reporting period. This strategy carries with it
associated costs, however, and was not employed by the Portfolio during the
reporting period. During this time, the U.S. dollar gained an average 4% against
the European currencies and close to 10% against the Japanese yen and emerging
market currencies. Most of the funds we invest in are adopting dynamic currency
hedging strategies designed to frequently evaluate their hedged portfolios, and
as a result the hedge ratios have been gradually reduced over the past six
months. Because of these hedging strategies, overall, the Portfolio has been
fairly well protected from the volatility in exchange rates.
 
Q. HOW DID THE PORTFOLIO'S STRATEGY CHANGE DURING THE REPORTING PERIOD, AND HOW
WAS IT POSITIONED VERSUS ITS BENCHMARK AT THE CLOSE OF THE PERIOD?
 
A. After reducing our positions in Latin America and eastern Europe in the
aftermath of the turmoil in Asia, we began rebuilding them by the close of the
period. In addition to further increasing our exposure to Europe, we also
broadened the country mix and capitalization style of our investments in Europe
by including the peripheral countries, such as Turkey, Greece and Portugal,
along with smaller-cap stocks.

NOTES TO FINANCIAL STATEMENTS
For the six months ended April 30, 1998 (Unaudited)
 
1. DESCRIPTION OF THE FUNDS
 
The Schwab MarketManager Growth Portfolio-TM- (formerly Schwab One Source
Portfolios--Growth Allocation Fund), Schwab MarketManager Balanced Portfolio-TM-
(formerly Schwab One Source Portfolios--Balanced Allocation Fund), Schwab
MarketManager Small Cap Portfolio-TM- (formerly Schwab One Source
Portfolios--Small Company Fund) and Schwab MarketManager International
Portfolio-TM- (formerly Schwab One Source Portfolios--International Fund) (the
"Funds") are series of Schwab Capital Trust (the "Trust"), a no-load, open-end,
investment management company organized as a Massachusetts business trust on May
7, 1993 and registered under the Investment Company Act of 1940, as amended (the
"1940 Act").
 
In addition to the Funds, the Trust also offers the Schwab S&P 500 Fund, Schwab
International Index Fund-Registered Trademark-, Schwab Small-Cap Index
Fund-Registered Trademark-, Schwab MarketTrack All Equity Portfolio-TM-
(effective on April 16, 1998, and commenced operations on May 19, 1998), Schwab
MarketTrack Growth Portfolio-TM- (formerly Schwab Asset
Director-Registered Trademark---High Growth Fund), Schwab MarketTrack Balanced
Portfolio-TM- (formerly Schwab Asset Director-Registered Trademark--- Balanced
Growth Fund), Schwab MarketTrack Conservative Portfolio-TM- (formerly Schwab
Asset Director-Registered Trademark--- Conservative Growth Fund) and Schwab
Analytics Fund-Registered Trademark-. The assets of each series are segregated
and accounted for separately.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
The following significant accounting policies are in conformity with generally
accepted accounting principles for investment companies. The preparation of
financial statements in accordance with generally accepted accounting principles
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.
 
SECURITY VALUATION--Investments in underlying funds are valued at their
respective net asset values as determined by those funds, in accordance with the
1940 Act, for a given day. Investments in securities traded on an exchange and
unlisted securities are valued at the last quoted sale price on the exchange on
which such securities are primarily traded, or if a sale is not reported for
that day, at the mean between the most recent bid and asked prices. Other
investments, for which no quotations are readily available, are valued at fair
value as determined by the Funds' investment manager pursuant to guidelines
adopted in good faith by the Board of Trustees.
 
SECURITY TRANSACTIONS AND INVESTMENT INCOME--Security transactions are accounted
for on a trade date basis (date the order to buy or sell is executed). Realized
gains and losses from security transactions are determined on an identified cost
basis. Dividend income and distributions to shareholders are recorded on the
ex-dividend date. Interest income is accrued on a daily basis.
 
DEFERRED ORGANIZATION COSTS--Costs incurred in connection with the organization
of the Funds and their initial registration with the Securities and Exchange
Commission are amortized on a straight-line basis over a five-year period from
each Fund's commencement of operations.
 
32
<PAGE>
 
EXPENSES--Expenses arising in connection with a Fund are charged directly to
that Fund. Expenses common to all series of the Trust are generally allocated to
each series in proportion to their relative net assets.
 
FEDERAL INCOME TAXES--It is each Fund's policy to meet the requirements of the
Internal Revenue Code applicable to regulated investment companies and to
distribute all net investment income and realized net capital gains, if any, to
shareholders. Therefore, no federal income tax provision is required. Each Fund
is considered a separate entity for tax purposes.
 
At April 30, 1998 (for financial reporting and federal income tax purposes:)

NOTES TO FINANCIAL STATEMENTS (continued)
 
officers or trustees who are "interested persons" within the meaning of the 1940
Act, as amended. The Funds incurred fees aggregating $17,000 related to the
Trust's unaffiliated trustees.
 
4. EXPENSES REDUCED AND ABSORBED BY THE INVESTMENT MANAGER AND SCHWAB
 
The Investment Manager and Schwab guarantee that, through at least February 28,
1999, each Fund's total operating expenses will not exceed 0.50% of the Fund's

guarantee, operating expenses do not include interest expenses, extraordinary
expenses, taxes, foreign taxes and capital items. Schwab has agreed to waive its
Transfer Agent and Shareholder Services fees through at least December 31, 2001.
 
For the period ended April 30, 1998, the total of such fees and expenses reduced
