     The first half of 2000 was an extraordinary period for the U.S. stock
market. Several major shifts in investor sentiment led to unprecedented levels
of volatility.

     The strong U.S. economy--and the accompanying rise in interest rates--was
one key factor. But so was the "New Economy"--the burgeoning technology and
telecommunications industries. Investors began to question the high valuations
of many New Economy stocks, casting doubt on their profitability and long-term
potential for success.

     As a result, the stock market grew increasingly volatile. For example, the
tech-heavy Nasdaq Composite Index lost more than 25% in a single week in early
April, then enjoyed one of its best months ever in June.

     For the most part, American Century's quantitative equity funds
successfully weathered this unusual and rapidly changing environment. Our
investment professionals review the period and the funds' performance in more
detail beginning on page 3.

     We're proud to announce that American Century's fund performance reports,
like this one, earned the Communications Seal from DALBAR, Inc., an independent
financial services research firm. DALBAR commended us for meeting investors'
needs with an attractive document that's easy to read and understand.

     We're also pleased to provide investors with two new investment tools. Fund
Advisor,(1) an online advice engine, is designed to give impartial guidance in
choosing the right no-load mutual funds to meet your financial goals.(2) And
American Century is the program manager for Learning Quest,(SM) an educational
savings program launched by the state of Kansas on July 1 that allows parents to
invest tax-deferred to meet higher education costs. The summer issue of the
American Century investor newsletter provides more details on these tools.

     As always, we appreciate your continued confidence in American Century.

Sincerely,
/s/James E. Stowers, Jr.                               /s/James E. Stowers III

Report Highlights
--------------------------------------------------------------------------------

MARKET PERSPECTIVE

*   U.S. stocks posted mixed returns in a volatile first half of 2000.

*   Small- and mid-cap stocks perform-ed well, while large-cap stocks fell
    slightly.

*   New Economy stocks (technology and telecommunications) soared early in the
    year, plunged in April and May, and then rebounded in June.

*   During the tech sell-off, investors shifted into undervalued sectors of the
    market that had been languishing earlier in the year.

*   Economic uncertainty and the speculative fervor surrounding New Economy
    stocks caused greater day-to-day volatility.

EQUITY GROWTH

*   The fund posted a slightly negative return but outperformed the S&P 500.

*   Equity Growth beat the index because of its focus on growth stocks (which
    outperformed value shares) and good stock selection.

*   Among technology stocks, the fund benefited the most from companies that
    supply components and infrastructure for electronic devices.

*   Equity Growth's health care and energy stocks were also strong performers.

*   Financial services stocks and retailers had a negative impact on fund
    performance, as did stock selection among computer hardware stocks.

INCOME & GROWTH

*   The fund produced a negative return in the first half of 2000 and trailed
    the S&P 500.

*   Income & Growth underperformed the index because of weakness in large-cap
    value stocks and poor stock selection.

*   The fund's semiconductor and computer hardware stocks posted strong returns,
    but stock selection within these industries hurt fund performance relative
    to the S&P 500.

*   Income & Growth benefited from stock selection among health care, computer
    software, and defense/aerospace companies.

*   Telephone, home products, and retail stocks detracted from fund performance.

SMALL CAP QUANTITATIVE

*   The fund posted a strong return and outperformed the S&P SmallCap 600.

*   Most of Small Cap Quantitative's outperformance occurred in the first
    quarter of the year, when the fund's technology and biotechnology stocks
    soared.

*   One of the main themes in the portfolio was the human genome project, which
    provided a boost to the fund's biotech stocks.

*   Another theme was the wireless industry--many of Small Cap Quantitative's
    best-performing stocks were tech companies that make circuitry or components
    for wireless devices.

*   Energy and food & beverage stocks also contributed positively to fund
    performance.

*   Basic materials stocks, information services firms, and retailers had the
    biggest negative impact on fund performance.

Market Perspective from Mark Mallon
--------------------------------------------------------------------------------
[photo of Mark Mallon]
Mark Mallon, head of growth and income equity, specialty, and asset allocation
funds at American Century

OVERVIEW

     Volatility was the watchword in the U.S. stock market during the first half
of 2000. Uncertainty about the economy, inflation, and interest rates--along
with the mood swings symptomatic of "dot-com fever"--led to wide fluctuations in
the major stock indexes.

     Large-cap stocks posted slightly negative returns, while small- and mid-cap
stocks fared better (see the table at right).

RUNNING WITH THE PACK

     After finishing 1999 at record highs, the major stock indexes stumbled out
of the gate in 2000. However, technology and telecommunications stocks--also
known as "New Economy" stocks-- continued to soar, extending their phenomenal
1999 performance. Investors discarded "Old Economy" stocks and snapped up shares
of dot-coms and other tech-oriented firms.

     This herd-like behavior pushed the Nasdaq Composite Index, which is
dominated by tech stocks, up by nearly 25% from the end of 1999 to its peak on
March 10, 2000. In contrast, the S&P 500 declined by 5%.

     But the speculative fervor surrounding New Economy stocks contributed to
greater market volatility. Day-to-day swings of 2% or more in the major stock
indexes became increasingly common as investors scurried from dot-com to
dot-com, trying to latch on to the next Yahoo! or Amazon.

SHIFTING GEARS

     By March, disillusionment brought a sudden change in market sentiment. A
series of interest rate increases by the Federal Reserve threatened to cool off
the hot U.S. economy, which grew at its fastest rate in almost 16 years in the
fourth quarter of 1999. In addition, concerns surfaced about sustainability and
profitability in the New Economy, especially among electronic-commerce and other
Internet-related companies.

     As a result, many investors began to turn away from high-flying growth
stocks, seeking out opportunities in undervalued sectors of the market or
sitting on the sidelines entirely. Between mid-March and late May, the Nasdaq
fell 37%, including a record 25% plunge in the second week of April, while the
S&P 500 edged 1% lower.

     After this deflation of the New Economy balloon, growth stocks staged a
solid comeback in June. However, the market remained volatile amid mixed signals
about the economy's strength and future Fed interest rate policy.

SMALL WONDERS

     After being left behind in 1998 and 1999, small- and mid-cap stocks
attracted more attention during the first half of 2000, outperforming
large-company stocks. Aggressive investors were especially fond of mid-cap
stocks because they had the high growth potential of smaller companies and the
ease of trading associated with larger stocks.

"DAY-TO-DAY SWINGS OF 2% OR MORE IN THE MAJOR STOCK INDEXES BECAME INCREASINGLY
COMMON."

Equity Growth--Q&A
--------------------------------------------------------------------------------
[photo of Jeff Tyler]

     An interview with Jeff Tyler, a portfolio manager on the Equity Growth fund
investment team.

HOW DID EQUITY GROWTH PERFORM DURING THE FIRST HALF OF 2000?

     The fund posted a slightly negative return but outperformed its benchmark,
the S&P 500. Equity Growth's six-month return was -0.22%, compared with the
-0.42% return of the S&P 500.*

     Equity Growth didn't do as well within its peer group--the fund's return
trailed the 2.53% average return of the 414 multi-cap core funds tracked by
Lipper Inc. (See the previous page for more fund performance comparisons.)

WHY DID THE FUND UNDERPERFORM ITS PEER GROUP AVERAGE?

     The multi-cap category consists of funds that do not concentrate solely on
one capitalization sector. Although Equity Growth can and does invest in small-
and mid-cap stocks, its main focus is on large-cap stocks. Therefore, when
small- and mid-cap stocks outperform large-caps--as they did in the past six
months--we're more likely to fall short of the category average.

     Over the long term, the fund has had better success within its Lipper
category (see the previous page). But our most important target is the fund's
performance benchmark. We're out to beat the S&P 500, as we did during the
six-month period and over the fund's nine-year existence.

THE FUND HAS AN EXCELLENT LONG-TERM RECORD, BUT LET'S LOOK AT THE MOST RECENT
SIX-MONTH PERIOD. WHAT FACTORS HELPED EQUITY GROWTH OUTPERFORM THE S&P 500?

     Our growth orientation was one key factor. Within the S&P 500, growth
stocks outperformed value shares by more than six percentage points.

     The rest of it came down to successful stock picking. Our results were a
bit mixed, but more often than not, our stock selection models put us in the
right places at the right times.

     Actually, these two factors blend together within our quantitative stock
selection model.

HOW SO?

     The fund's slight bias toward growth is embedded in the computer model that
picks stocks for the portfolio. This model has always incorporated both growth
measures (such as earnings growth and earnings surprises) and value measures
(such as price/earnings and price/book ratios) into its stock-ranking process.

     Within the last year, though, we adjusted the model to emphasize growth
more than value when ranking stocks. We took this a step further when it came to
technology stocks--we now use growth measures almost exclusively when evaluating
companies in this sector.

     We give these stock picks what we call a "reasonableness check" and then
run them through another computer model, which puts in a few risk controls and
keeps our industry weightings close to those in the S&P 500. The end result is a
diversified portfolio of stocks with a definite growth tilt.

Equity Growth--Q&A
--------------------------------------------------------------------------------
                                                                    (Continued)

CAN YOU GIVE SOME EXAMPLES OF YOUR SUCCESSFUL STOCK PICKS?

     Technology is a good place to start, since it was the most active and
volatile sector of the market. One of the themes among technology stocks was a
shift away from manufacturers and toward companies that build infrastructure or
provide supplies and components to these manufacturers.

     An example from Equity Growth's portfolio is Applied Materials (up 43%
during the first half of the year), which makes equipment for semiconductor
manufacturers. Increased demand for personal computers, cellular phones, and
other electronic devices caused chip makers to boost production, and that in
turn created strong demand for manufacturing equipment.

WHERE ELSE HAS THIS THEME TAKEN HOLD?

     We've seen it among companies involved in producing fiber-optic equipment
and components. Fiber-optic networks are the backbone of the developing
infrastructure for high-speed Internet access and data transmission.

     A good example is Corning (up 110%), which produces glass fibers for
telecommunications networks. The company is growing as fast as it possibly can
and still has a backlog of orders for its products. Equity Growth held a
substantial overweight in Corning for much of the past six months.

     Other top-performing overweights included Integrated Device Technology (up
106%), which produces computer chips for telecommunications; Scientific-Atlanta
(up 167%), which makes set-top boxes that connect digital cable and the Internet
to your TV or computer; and Vishay Intertechnology (up 80%), one of the largest
manufacturers of electronic components and circuitry for cell phones.

THOSE ARE SOME PRETTY BIG WINNERS. ANY LOSERS AMONG TECHNOLOGY STOCKS?

     Definitely. Even though Equity Growth's tech stocks outperformed those in
the S&P 500 as a group, there were plenty of missteps to offset our successes.

     For example, the fund was underweight in the S&P 500's two biggest
semiconductor stocks, Intel (up 62%) and Texas Instruments (up 42%). In fact,
six months ago we didn't own even a single share of Intel. That turned out to be
our worst individual decision in terms of lost performance relative to the
index.

     Stock selection among computer hardware companies was also a weak spot.
Fund overweights in Adaptec (down 54%) and Electronics For Imaging (down 56%)
--both of which are no longer in the portfolio--more than offset a beneficial
overweight in Hewlett-Packard (up 38%).

     And of course there's Microsoft, the fund's biggest holding six months ago.
Microsoft's antitrust violations and a possible break-up by the Justice
Department pushed its stock price down by more than 30%. We cut back our
holdings to an underweight position compared with the S&P 500, but Microsoft is
still the fund's third-largest holding.

HOW DID THE PORTFOLIO FARE IN OTHER SECTORS OF THE MARKET?

     Health care and energy stocks were by far the best sectors in the
portfolio. Equity Growth was neutral overall in health care, but we were
overweight drug and biotechnology stocks and underweight medical products
companies.

Equity Growth--Q&A
--------------------------------------------------------------------------------
                                                                    (Continued)

     The fund's largest overweights in this sector were two big pharmaceutical
stocks, Pfizer (up 49%) and Warner-Lambert (up 59%). Pfizer, which makes five of
the world's 20 top-selling medicines, recently acquired Warner-Lambert,
providing a boost to both stocks.

     Equity Growth also had several biotech holdings that performed very well.
The near-completion of the human genome project generated a great deal of
excitement in these stocks. Small holdings in IVAX (up 142%), Andrx (up 202%),
and Vertex Pharmaceuticals (up 204%) enhanced fund performance.

     Among energy stocks, our biggest overweights included Amerada Hess (up 9%),
Apache (up 59%), and Union Pacific Resources (up 74%). These companies are among
the leading oil and natural gas exploration companies, and they benefited from a
30% rise in the price of oil.

AND ON THE NEGATIVE SIDE?

     Financial stocks, especially banks, were among the portfolio's weakest
performers. Rising interest rates led to reduced lending activity, and that in
turn squeezed profit margins at many banks. Fund overweights in Chase Manhattan
(down 10%), UnionBanCal (down 52%), and Bank of America (down 13%) were a drag
on fund performance.

     Retailers were also something of a disaster area, hurt by worries of a
slowdown in consumer spending. Equity Growth was overweight in Home Depot (down
27%) and top-ten holding Wal-Mart (down 16%), and also held small positions in
decreasingly popular teenage clothing stores like Abercrombie & Fitch (down 54%)
and American Eagle Outfitters (down 69%). These last two stocks are no longer in
the portfolio.

LOOKING AHEAD, WHAT DO YOU SEE IN STORE FOR THE U.S. STOCK MARKET FOR THE REST
OF THE YEAR?

     The slight decline in the S&P 500 during the first half of the year allowed
corporate earnings to catch up a bit with the rise in stock prices over the past
several years. Instead of the 25% annual returns that the S&P 500 posted in
recent years, we expect equity returns to be more in line with corporate
earnings growth as we move forward.

     That said, we also believe that we're closer to the beginning than the end
of the shakeout among technology companies, and that could mean more volatility
in the coming months.

     Investors are taking a harder look at the long-term business plans and
profitability of their technology investments. Prior to this year, venture
capital for technology start-ups flowed freely, and tech firms were going public
at a rate of several per week. In the past six months, however, the market for
initial public offerings dried up, and venture capital became increasingly hard
to get.

     As the tech sector continues to evolve, we expect to see more
consolidation. A large number of companies that were built on promises and
little else will likely be bought out or disappear completely. In the end,
though, we expect the survivors to be stronger and in a better position to be
successful and profitable companies over the long term.

WHAT ARE YOUR PLANS FOR EQUITY GROWTH IN THE COMING MONTHS?

     Our goal is to outperform the S&P 500 by remaining fully invested in U.S.
stocks and using our quantitative models to help us pick the best stocks in each
industry of the market. That objective won't change.

The graph at left shows the growth of a $10,000 investment over the life of the
fund, while the graph below shows the fund's year-by-year performance. The S&P
500 is provided for comparison in each graph. Income & Growth's total returns
include operating expenses (such as transaction costs and management fees) that
reduce returns, while the total returns of the index do not. These graphs are
based on Investor Class shares only; performance for other classes will vary due
to differences in fee structures (see Total Returns table above). Past
performance does not guarantee future results. Investment return and principal
value will fluctuate, and redemption value may be more or less than original
cost.

Income & Growth--Q&A
--------------------------------------------------------------------------------
[photo of John Schniedwind]   [photo of Kurt Borgwardt]

     An interview with John Schniedwind and Kurt Borgwardt, portfolio managers
on the Income & Growth fund investment team.

HOW DID INCOME & GROWTH PERFORM DURING THE FIRST HALF OF 2000?

     The fund's six-month return of -3.55% reflected the general weakness of
large-cap stocks.* Income & Growth's performance trailed the -0.42% return of
its benchmark, the S&P 500, as well as the -1.65% average return of the 382
large-cap value funds tracked by Lipper Inc. (See the previous page for other
fund performance comparisons.)

WHY DID THE FUND UNDERPERFORM BOTH THE S&P 500 AND THE AVERAGE LARGE-CAP VALUE
FUND?

     We focus on the S&P 500 as our performance target, so we're less concerned
with how our returns stack up against the average large-cap value fund. If we
can consistently beat the S&P 500, our peer group performance should take care
of itself. (See the previous page for the fund's long-term record against its
peer group.)

     With regard to the index, part of the reason we lagged was the
outperformance of growth stocks over value stocks in the large-cap market. We
incorporate both growth and value measures into our stock selection process, but
with a slight tilt toward value. This value bias hurt fund performance relative
to the S&P 500--the S&P/BARRA Growth Index returned 2.63% in the first half of
2000, while the S&P/BARRA Value Index returned -4.07%.

     But the main reason we underperformed the index--and the average large-cap
value fund, for that matter--was stock selection. Our industry-neutral approach
puts a heavy emphasis on the stock picking of our quantitative models, and
unfortunately this worked against us during the six-month period.

CAN YOU TALK A LITTLE MORE ABOUT YOUR INDUSTRY-NEUTRAL APPROACH AND STOCK
SELECTION PROCESS?

     "Industry neutral" means the fund's industry weightings typically match or
come close to the industry weightings of the S&P 500. In other words, we're not
making significant bets on technology, financials, or any other sector of the
market.

     This approach increases the importance of our stock selection. We try to
outperform the index by investing in the best-performing companies within each
industry. We use a quantitative analytical model--basically a sophisticated
computer program--that evaluates stocks and ranks them based on their growth
prospects and their relative value.

     The human element is also a key part of the process. We review the stock
picks within the context of supplemental information not already reflected in
the model.

      Ultimately, we try to own as many high-ranking stocks as we can, within
limitations. These limitations include our industry-neutral positioning, as well
as some controls that keep the fund's risk profile close to that of the S&P 500.

Income & Growth--Q&A
--------------------------------------------------------------------------------
                                                                    (Continued)

WERE THERE ANY SPECIFIC AREAS WHERE YOUR STOCK SELECTION WAS PROBLEMATIC?

     Some of the areas where our stock selection struggled the most were
actually ones that contributed positively to the fund's overall return.

     Semiconductor stocks are a good example. As a group, the fund's
semiconductor holdings returned about 50% in the first half of this year--the
best industry return in the portfolio. This performance was driven by strong
demand for personal computers, cellular phones, and other electronic devices
requiring computer chips. The stock prices of several fund holdings, including
Integrated Device Technology and Micron, more than doubled.

     However, the semiconductor stocks in the S&P 500 returned almost 60% as a
group. Income & Growth's underweights in the two largest semiconductor
companies, Intel (up 62% during the period) and Texas Instruments (up 42%), hurt
fund performance relative to the index. Our models downgraded these two stocks
because of their extremely high prices.

HOW DID THE FUND FARE IN THE REST OF THE TECHNOLOGY SECTOR?

     Electrical equipment stocks produced solid returns, especially in the first
quarter. Our best performers included Scientific-Atlanta (up 166%), which was a
fund overweight for most of the period, and Corning (up 110%).
Scientific-Atlanta makes set-top boxes that connect digital cable and the
Internet to a TV or computer, while Corning manufactures glass components for
fiber-optic telecommunications networks.

     Computer hardware stocks also performed well thanks to increased PC demand,
but our stock selection hurt us in this area. Although we made some good
decisions among the larger computer makers--overweights in Hewlett-Packard (up
38%) and Apple (up 2%), underweights in Gateway (down 21%) and Dell Computer
(down 3%)--these were overshadowed by heavy weightings in Adaptec (down 54%) and
Electronics For Imaging (down 56%).

     The opposite occurred in the fund's computer software holdings--overall
performance was weak, but our stock selection was favorable. We were overweight
Adobe (up 93%), which produces the leading desktop-publishing and photography
software, and we stayed away from BMC Software (down 54%) and Parametric
Technology (down 59%), both of which reported disappointing earnings.

     The anti-trust trial and proposed break-up of the biggest software company
of all--Microsoft (down 31%)--weighed heavily on its stock price and the fund's
performance. We shifted to an underweight position in Microsoft relative to the
S&P 500, but it remained one of the fund's largest holdings.

WHAT OTHER SECTORS OF THE MARKET HAD THE BIGGEST IMPACT ON FUND PERFORMANCE?

     On the positive side, health care was Income & Growth's best sector,
especially in the second quarter. This included our holdings among drug, medical
products, and medical services stocks.

     Evidence of a slower U.S. economy boosted demand for drug stocks, which
tend to produce steady profit growth regardless of economic conditions. The
large drug stocks were also considered a safety play for investors as they
rotated out of technology stocks in the second quarter.

Income & Growth--Q&A
--------------------------------------------------------------------------------
                                                                    (Continued)

     Among pharmaceutical firms, the fund benefited from an overweight in Pfizer
(up 50%). The company completed the acquisition of one of its biggest
competitors, Warner-Lambert, creating the world's largest pharmaceuticals
company.

     Our stock selection among defense and aerospace stocks was significantly
positive. The fund was overweight in Northrop Grumman (up 25%), which sold many
of its low-profit businesses and saw increased orders for its airplanes. In
addition, we didn't own any shares in Honeywell (down 41%) and Raytheon (down
27%).

WHAT ABOUT HOLDINGS THAT DETRACTED FROM FUND PERFORMANCE?

     Telephone stocks declined across the board. They went through a sizable
correction after a huge run-up in 1999. The good news is that we were
underweight in two of the worst performers, AT&T (down 37%) and Global Crossing
(down 47%).

     In addition, home products companies contributed negatively to fund
performance. The biggest damage was done by Procter & Gamble (down 47%), which
posted disappointing earnings in two consecutive quarters.

     Retailers, from department stores to home improvement warehouses, were also
weak performers. Clothing stores like Abercrombie & Fitch (down 54%) and
American Eagle Outfitters (down 69%) were trounced because of concerns about
declining popularity and market share among teenagers. The fund no longer held
these stocks by the end of June.

LOOKING AHEAD, WHAT DO YOU SEE IN STORE FOR THE U.S. STOCK MARKET FOR THE REST
OF THE YEAR?

     The performance of the stock market during the second half of 2000 will
hinge on how successful the Federal Reserve is in achieving a "soft landing"
--slowing the economy to a moderate, sustainable growth rate while keeping a lid
on inflation.

     So far, the economy has remained healthy, but we're finally starting to see
some evidence that the Fed's six interest rate increases over the past year are
slowing things down.

     If the Fed pulls this off successfully, as it did in 1995, it would be
positive for the stock market. If the Fed is unsuccessful--either by failing to
stay ahead of the inflation curve or tightening the screws too hard, causing a
recession--stocks could weaken along with corporate earnings.

     We're not likely to see greater market volatility than in the first half of
the year--that would be hard to imagine--but we don't think it will go away any
time soon, either.

WHAT ARE YOUR PLANS FOR INCOME & GROWTH IN THE COMING MONTHS?

     We intend to keep following the same disciplined, quantitative approach,
seeking out what our models indicate are the best companies in each industry of
the market.

* Futures contracts typically are based on a stock index, such as the S&P 500,
  and tend to track the performance of the index while remaining very liquid
  (easy to buy and sell). By investing its cash assets in index futures, the
  fund can have full exposure to stocks and have easy access to the money.
  Temporary cash investments, less the required reserves for futures contracts,
  are 0.4%.

The graph at left shows the growth of a $10,000 investment over the life of the
fund. The S&P SmallCap 600 Index is provided for comparison. Small Cap
Quantitative's return includes operating expenses (such as transaction costs and
management fees) that reduce returns, while the return of the index does not.
Past performance does not guarantee future results. Investment return and
principal value will fluctuate, and redemption value may be more or less than
original cost.

Small Cap Quantitative--Q&A
--------------------------------------------------------------------------------
[photo of Bill Martin]   [photo of Matti von Turk]

     An interview with Bill Martin and Matti von Turk, portfolio managers on the
Small Cap Quantitative fund investment team.

HOW DID SMALL CAP QUANTITATIVE PERFORM DURING THE FIRST HALF OF 2000?

     The fund outperformed both its performance benchmark and the average return
of its peer group. Small Cap Quantitative's six-month return was 9.29%, compared
with the 6.93% return of its benchmark, the S&P SmallCap 600, and the 9.20%
average return of the 217 small-cap core funds tracked by Lipper Inc.* (See the
previous page for other fund performance comparisons.)

WHY DID THE FUND PERFORM SO WELL COMPARED WITH ITS BENCHMARK INDEX?

     Most of the fund's outperformance came in the first quarter of the year,
when technology and biotechnology stocks were leading the small-cap market
higher. Our stock selection among tech and biotech companies was quite
successful--eight of Small Cap Quantitative's best performers were in these two
sectors--and it gave us a leg up on the index.

CAN YOU GIVE A REFRESHER ON YOUR  STOCK-PICKING PROCESS?

     We use a computer model to analyze and rank about 1,500 small-cap stocks.
The model is structured to strike a balance between growth and value, and it
combines several growth and value components into a blended stock-picking
approach. The main component of the model is GARP, which stands for "growth at a
reasonable price."

     We use a slightly different model to evaluate technology stocks. We found
that the GARP element was not very effective when it came to tech stocks.
Instead, the model focuses on "growth on a sustainable basis." This new model
has worked well since we began using it at the beginning of the year.

     An important part of the stock-picking process is our own analysis. We give
the model's results a "reasonableness check" and review additional information
outside of the model that may affect the rankings.

AND YOU JUST INVEST IN THE HIGHEST- RANKING STOCKS?

     Sort of. Our performance target is the S&P SmallCap 600, which we think is
an excellent diversified representation of the small-cap market. We want Small
Cap Quantitative to have many of the same basic characteristics as the index, so
we run our model's favorite stock picks through an "optimizer." This is another
computer program that makes sure the portfolio's industry weightings and risk
features are similar to those of the index.

     We count on our stock-picking model to select the stocks that provide the
highest return potential, and we rely on the optimizer to control risk and keep
the fund from straying too far from the index.

* All fund returns referenced in this interview are for Investor Class shares.

     Health care was our best sector, mainly because of the strong performance
of biotechnology stocks. The catalyst was the effort to map out the human genome
and the vast potential for using this knowledge to fight disease. The attention
surrounding the project provided a boost to the entire biotech industry.

     The fund held overweights in several top-performing biotech stocks.
Examples included Vertex Pharmaceuticals (up 204% for the six-month period) and
Protein Design Labs (up 136%).

     Another favorable overweight--the biggest one currently in the
portfolio--was IDEC Pharmaceuticals (up 19%). IDEC, which has successfully
developed several cancer-treatment therapies, was Small Cap Quantitative's
largest holding six months ago and is still in the fund's top ten.

YOU MENTIONED EARLIER THAT TECHNOLOGY STOCKS WERE ALSO STRONG PERFORMERS. WHAT
STOCKS DID YOUR MODELS LIKE IN  THIS AREA?

     There were a couple of themes within our technology holdings. The first was
the huge demand for wireless devices like cellular phones and mobile radios. In
1999, cell phone sales numbered 200 million units, and that's expected to more
than double this year.

     We focused on companies that make circuitry and components for the wireless
industry. A great example is Powerwave Technologies (up 126%), which makes
amplifiers that increase the signal strength of wireless devices. Another top
performer was Vishay Intertechnology (up 80%), the largest maker of electronic
components for cell phones.

     These stocks soared in the first part of the year, but they got beaten up a
little in June as analysts began to reduce their forecasts for wireless demand.
Still, many of these companies have order backlogs beyond the end of this year,
and their earnings continue to grow extremely fast.

     Another theme was the expansion of demand for computer chips.

DID THIS ALSO STEM FROM THE WIRELESS EXPLOSION?

     Exactly. Chips are now used in everything from cell phones to hand-held
computers. As a result, earnings at semiconductor companies soared, attracting
the attention of our models.

     One of our biggest overweights was Integrated Device Technology (up 106%),
a company that has been increasing its production of chips for
telecommunications equipment. Other good performers included International
Rectifier (up 115%), which manufactures chips for electrical power conversion,
and Burr-Brown (up 140%), which was recently acquired by Texas Instruments.

     That was another minor theme in the portfolio--several fund holdings were
acquired by other companies.

IS THAT WHY YOU WERE INVESTED IN THOSE COMPANIES?

     No, it's just part of the landscape in the small-cap market. Smaller firms
are often acquisition targets for larger companies looking to expand or
diversify. In some cases, a company simply wants to join forces with a growing
competitor.

     Other fund holdings involved in acquisitions included Ben & Jerry's (up
76%), the socially responsible ice cream maker that was bought by Unilever, and
US Trust (up 83%), a financial services firm bought by Charles Schwab.

Small Cap Quantitative--Q&A

WHAT ABOUT OTHER AREAS IN THE PORTFOLIO?

     Energy stocks benefited from rising oil and gasoline prices. Our best
performers included Vintage Petroleum (up 87%), the fund's second-largest
holding, and Oceaneering International (up 27%).

     Food and beverage stocks were also positive contributors to fund
performance, especially when evidence of slower economic growth appeared in the
second quarter. Food and beverage stocks tend to be less sensitive to the ebbs
and flows of the economy, so they become most attractive when the economy
weakens.

     In addition to good performance from Ben & Jerry's, we benefited from an
overweight in Earthgrains (up 21%), one of our top ten holdings. Earthgrains
makes bread and other baked goods, both in the U.S. and in several overseas
markets.

WE HAVEN'T HEARD ANY BAD NEWS YET. WERE ALL OF THE FUND'S STOCKS UP DURING THE
PERIOD?

     Not at all. There are always going to be some disappointments in the
portfolio. The weakest performers across the board were basic materials
stocks--chemicals, forest products, and mining companies. Chemical company
profits were hurt by rising oil and raw materials prices, while many forest
product and mining stocks felt the sting of higher interest rates, which slowed
the economy in general and the housing market in particular.

     Another area hit hard by rising rates was retail stores and other cyclical
consumer stocks. Perceptions of reduced consumer spending weighed on many of
these companies.

     Technology consulting firms seemed to have a cloud hanging over them.
First, they lost a major source of revenue when Y2K came and went without a
hitch. Then Internet companies began to see their funding dry up, and
consultants were the first to go.

     Our worst individual performer was a consulting firm called Marchfirst
(down 66%). The company acquired two other companies but had difficulty
integrating them, and employee turnover was very heavy. We still like
Marchfirst's prospects--its earnings are growing rapidly, and the stock now
looks very attractive from a value perspective.

LOOKING AHEAD, WHAT DO YOU SEE IN STORE FOR SMALL-CAP STOCKS DURING THE REST OF
THE YEAR?

     After lagging large-cap stocks for the past few years, small-cap stocks are
finally attracting some attention from investors. The outlook is still bright
for small-caps--earnings growth remains healthy, and despite their recent
outperformance, small-cap stocks continue to have lower valuations than
large-caps.

     Right now, we appear to be in a transitional period that is wringing some
of the past excesses out of the market. That's likely to mean more of the
extreme day-to-day volatility we saw in the first half of the year.

     The economy may also be an important factor in the second half of the year.
More interest rate increases by the Federal Reserve or further evidence of
slower economic growth could lead to weaker corporate earnings and lower stock
prices.

WHAT ARE YOUR PLANS FOR SMALL CAP QUANTITATIVE IN THE COMING MONTHS?

     We intend to stay true to our long-term investment approach, staying fully
invested in small-cap stocks and relying on our quantitative models to steer us
toward the best companies in each industry.

* Futures contracts typically are based on a stock index, such as the S&P 500,
  and tend to track the performance of the index while remaining very liquid
  (easy to buy and sell). By investing its cash assets in index futures, the
  fund can have full exposure to stocks and have easy access to the money.
  Temporary cash investments, less the required reserves for futures contracts,
  are 0.1%.

Statement of Assets and Liabilities
--------------------------------------------------------------------------------

This statement breaks down the fund's ASSETS (such as securities, cash, and
other receivables) and LIABILITIES (money owed for securities purchased,
management fees, and other liabilities) as of the last day of the reporting
period. Subtracting the liabilities from the assets results in the fund's NET
ASSETS. For each class of shares, the net assets divided by shares outstanding
is the share price, or NET ASSET VALUE PER SHARE. This statement also breaks
down the fund's net assets into capital (shareholder investments) and
performance (investment income and gains/losses).

JUNE 30, 2000 (UNAUDITED)

1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    ORGANIZATION -- American Century Quantitative Equity Funds (the corporation)
is registered under the Investment Company Act of 1940 (the 1940 Act) as an
open-end management investment company. Equity Growth Fund (Equity Growth),
Income & Growth Fund (Income & Growth) and Small Cap Quantitative Fund (Small
Cap Quantitative) (the funds) are three of the six funds issued by the
corporation. The funds are diversified under the 1940 Act. Equity Growth seeks
capital appreciation by investing in common stocks. Income & Growth seeks
dividend growth, current income and capital appreciation by investing in common
stocks. Small Cap Quantitative seeks long-term capital appreciation by investing
primarily in equity securities of small companies. The following significant
accounting policies are in accordance with generally accepted accounting
principles; these policies may require the use of estimates by fund management.

    MULTIPLE CLASS -- Each fund is authorized to issue three classes of shares:
the Investor Class, the Advisor Class and the Institutional Class. The three
classes of shares differ principally in their respective shareholder servicing
and distribution expenses and arrangements. All shares of each fund represent an
equal pro rata interest in the net assets of the class to which such shares
belong, and have identical voting, dividend, liquidation and other rights and
the same terms and conditions, except for class specific expenses and exclusive
rights to vote on matters affecting only individual classes. Sale of the Advisor
Class for Small Cap Quantitative had not commenced as of the report date.

    SECURITY VALUATIONS -- Portfolio securities traded primarily on a principal
securities exchange are valued at the last reported sales price, or at the mean
of the latest bid and asked prices where no last sales price is available.
Securities traded over-the-counter are valued at the mean of the latest bid and
asked prices or, in the case of certain foreign securities, at the last reported
sales price, depending on local convention or regulation. When valuations are
not readily available, securities are valued at fair value as determined in
accordance with procedures adopted by the Board of Directors.

    SECURITY TRANSACTIONS -- Security transactions are accounted for as of the
trade date. Net realized gains and losses are determined on the identified cost
basis, which is also used for federal income tax purposes.

    INVESTMENT INCOME -- Dividend income less foreign taxes withheld (if any) is
recorded as of the ex-dividend date. Interest income is recorded on the accrual
basis and includes accretion of discounts and amortization of premiums.

    FUTURES CONTRACTS -- The funds may enter into stock index futures contracts
in order to manage the funds' exposure to changes in market conditions. One of
the risks of entering into futures contracts is the possibility that the changes
in value of the contract may not correlate with the changes in value of the
underlying securities. Upon entering into a futures contract, the funds are
required to deposit either cash or securities in an amount equal to a certain
percentage of the contract value (initial margin). Subsequent payments
(variation margin) are made or received daily, in cash, by the funds. The
variation margin is equal to the daily change in the contract value and is
recorded as an unrealized gain or loss. The funds recognize a realized gain or
loss when the contract is closed or expires. Net realized and unrealized gains
or losses occurring during the holding period of futures contracts are a
component of realized gain (loss) on investments and unrealized appreciation
(depreciation) on investments, respectively.

    REPURCHASE AGREEMENTS -- The funds may enter into repurchase agreements with
institutions that the funds' investment manager, American Century Investment
Management, Inc. (ACIM), has determined are creditworthy pursuant to criteria
adopted by the Board of Directors. Each repurchase agreement is recorded at
cost. The funds require that the collateral, represented by securities, received
in a repurchase transaction be transferred to the funds' custodian in a manner
sufficient to enable the funds to obtain those securities in the event of a
default under the repurchase agreement. ACIM monitors, on a daily basis, the
securities transferred to ensure the value, including accrued interest, of the
securities under each repurchase agreement is greater than amounts owed to the
funds under each repurchase agreement.

    JOINT TRADING ACCOUNT -- Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the funds, along with other registered
investment companies having management agreements with ACIM, may transfer
uninvested cash balances into a joint trading account. These balances are
invested in one or more repurchase agreements that are collateralized by U.S.
Treasury or Agency obligations.

    INCOME TAX STATUS -- It is the funds' policy to distribute all net
investment income and net realized gains to shareholders and to otherwise
qualify as a regulated investment company under the provisions of the Internal
Revenue Code. Accordingly, no provision has been made for federal or state
income taxes.

    DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded
on the ex-dividend date. Distributions from net investment income are declared
and paid quarterly for the funds. Distributions from net realized gains for the
funds are expected to be declared and paid twice a year.

    The character of distributions made during the year from net investment
income or net realized gains may differ from their ultimate characterization for
federal income tax purposes. These differences reflect the differing character
of certain income items and net realized gains and losses for financial
statement and tax purposes, and may result in reclassification among certain
capital accounts.

    At December 31, 1999, Income & Growth and Small Cap Quantitative had
accumulated net realized capital loss carryovers for federal income tax purposes
of $1,698,568 and $89,383 (expiring in 2007), respectively, which may be used to
offset future taxable gains.

    ADDITIONAL INFORMATION -- Funds Distributor, Inc. (FDI) is a distributor of
the corporation. Certain officers of FDI are also officers of the corporation.

2.  TRANSACTIONS WITH RELATED PARTIES

    The corporation has entered into a Management Agreement with ACIM, under
which ACIM provides the funds with investment advisory and management services
in exchange for a single, unified management fee per class. The Agreement
provides that all expenses of the funds, except brokerage commissions, taxes,
portfolio insurance, interest, fees and expenses of the directors who are not
considered "interested persons" as defined in the 1940 Act (including counsel
fees) and extraordinary expenses, will be paid by ACIM. The fee is calculated
daily and paid monthly. It consists of an Investment Category Fee based on the
average net assets of the funds in a specific fund's investment category and a
Complex Fee based on the average net assets of all the funds managed by ACIM.
The rates for the Investment Category Fee range from 0.3380% to 0.5200% for
Equity Growth and Income & Growth and 0.5380% to 0.7200% for Small Cap
Quantitative. The rates for the Complex Fee (Investor Class) range from 0.2900%
to 0.3100%. The Advisor Class and the Institutional Class are 0.2500% less and
0.2000% less, respectively, at each point within the Complex Fee range. For the
six months ended June 30, 2000, the effective annual Investor Class management
fee was 0.67%, 0.67%, and 0.87%, for Equity Growth, Income & Growth, and Small
Cap Quantitative, respectively.

    The Board of Directors has adopted the Advisor Class Master Distribution and
Shareholder Services Plan (the plan), pursuant to Rule 12b-1 of the 1940 Act.
The plan provides that the funds will pay ACIM an annual distribution fee equal
to 0.25% and service fee equal to 0.25%. The fees are computed daily and paid
monthly based on the Advisor Class's average daily closing net assets during the
previous month. The distribution fee provides compensation for distribution
expenses incurred by financial intermediaries in connection with distributing
shares of the Advisor Class including, but not limited to, payments to brokers,
dealers, and financial institutions that have entered into sales agreements with
respect to shares of the funds. The service fee provides compensation for
shareholder and administrative services rendered by ACIM, its affiliates or
independent third party providers. Fees incurred under the plan during the six
months ended June 30, 2000, were $435,004 and $2,008,342 for Equity Growth and
Income & Growth, respectively.

    Effective March 13, 2000, American Century Investment Services, Inc. (ACIS),
became a distributor of the corporation.

    Certain officers and directors of the corporation are also officers and/or
directors, and, as a group, controlling stockholders of American Century
Companies, Inc., the parent of the corporation's investment manager, ACIM, a
distributor of the corporation, ACIS, and the corporation's transfer agent,
American Century Services Corporation.

This table itemizes investment results and distributions on a per-share basis to
illustrate share price changes for each of the last five fiscal years (or less,
if the share class is not five years old). It also includes several key
statistics for each reporting period, including TOTAL RETURN, INCOME RATIO (net
investment income as a percentage of average net assets), EXPENSE RATIO
(operating expenses as a percentage of average net assets), and PORTFOLIO
TURNOVER (a gauge of the fund's trading activity).

Share Class and Retirement Account Information
--------------------------------------------------------------------------------

SHARE CLASSES

    Three classes of shares are authorized for sale by the funds: Investor
Class, Advisor Class, and Institutional Class.

    INVESTOR CLASS shareholders do not pay any commissions or other fees for
purchase of fund shares directly from American Century. Investors who buy
Investor Class shares through a broker-dealer may be required to pay the
broker-dealer a transaction fee.

    ADVISOR CLASS shares are sold through banks, broker-dealers, insurance
companies, and financial advisors. Advisor Class shares are subject to a 0.50%
Rule 12b-1 service and distribution fee. Half of that fee is available to pay
for recordkeeping and administrative services, and half is available to pay for
distribution services provided by the financial intermediary through which the
Advisor Class shares are purchased. The total expense ratio of the Advisor Class
is 0.25% higher than the total expense ratio of the Investor Class. The Advisor
Class had not commenced as of June 30, 2000, for the Small Cap Quantitative
fund.

    INSTITUTIONAL CLASS shares are available to endowments, foundations,
defined-benefit pension plans, or financial intermediaries serving these
investors. This class recognizes the relatively lower cost of serving
institutional customers and others who invest at least $5 million in an American
Century fund or at least $10 million in multiple funds. In recognition of the
larger investments and account balances and comparatively lower transaction
costs, the total expense ratio of the Institutional Class is 0.20% less than the
total expense ratio of the Investor Class shares.

    All classes of shares represent a pro rata interest in the funds and
generally have the same rights and preferences.

RETIREMENT ACCOUNT INFORMATION

    As required by law, any distributions you receive from an IRA and certain
403(b) distributions [not eligible for rollover to an IRA or to another 403(b)
account] are subject to federal income tax withholding at the rate of 10% of the
total amount withdrawn, unless you elect not to have withholding apply. If you
don't want us to withhold on this amount, you may send us a written notice not
to have the federal income tax withheld. Your written notice is valid from the
date of receipt at American Century. Even if you plan to roll over the amount
you withdraw to another tax-deferred account, the withholding rate still applies
to the withdrawn amount unless we have received a written notice not to withhold
federal income tax prior to the withdrawal.

    When you plan to withdraw, you may make your election by completing our
Exchange/Redemption form or an IRS Form W-4P. Call American Century for either
form. Your written election is valid from the date of receipt at American
Century. You may revoke your election at any time by sending a written notice to
us.

    Remember, even if you elect not to have income tax withheld, you are liable
for paying income tax on the taxable portion of your withdrawal. If you elect
not to have income tax withheld or you don't have enough income tax withheld,
you may be responsible for payment of estimated tax. You may incur penalties
under the estimated tax rules if your withholding and estimated tax payments are
not sufficient.

Background Information
--------------------------------------------------------------------------------

INVESTMENT PHILOSOPHY AND POLICIES

     American Century's quantitative equity funds are managed using computer
models as key tools in making investment decisions. A stock-ranking model
analyzes a sizable universe of stocks based on their expected return. The model
looks at both growth and value measures such as cash flow, earnings growth, and
price/earnings ratio. Once the stocks are ranked, another model creates
portfolios that balance high-ranking stocks with an overall risk level that is
comparable to each fund's benchmark index.

     EQUITY GROWTH seeks capital appreciation by investing in a diversified
portfolio of common stocks. Its goal is to achieve a total return that exceeds
the total return of the S&P 500.

     INCOME & GROWTH seeks current income and capital appreciation by investing
in a diversified portfolio of common stocks. Its goal is to achieve a total
return that exceeds the total return of the S&P 500. The fund's management team
also targets a dividend yield that is higher than the yield of the S&P 500.

     SMALL CAP QUANTITATIVE seeks capital appreciation by investing in the
common stocks of smaller companies. Its goal is to achieve a total return that
exceeds the total return of the S&P SmallCap 600. Historically, small-cap stocks
have been more volatile than the stocks of larger, more-established companies.

COMPARATIVE INDICES

     The following indices are used in the report for fund performance
comparisons. They are not investment products available for purchase.

     The S&P 500 is composed of 500 large-capitalization stocks traded on
domestic exchanges. It is considered a broad measure of U.S. stock performance.

     The S&P MIDCAP 400 is composed of 400 mid-capitalization stocks traded on
domestic exchanges. It is considered a broad measure of mid-sized stock
performance.

     The S&P SMALLCAP 600 is composed of 600 small-capitalization stocks traded
on domestic exchanges. It is considered a broad measure of small-company stock
performance.

LIPPER RANKINGS

     LIPPER INC. is an independent mutual fund ranking service that groups funds
according to their investment objectives. Rankings are based on average annual
returns for each fund in a given category for the periods indicated. Rankings
are not included for periods of less than one year.

     The Lipper categories for the quantitative equity funds are:

     MULTI-CAP CORE FUNDS (Equity Growth) -- funds that invest in a variety of
market capitalizations and strike a balance between growth and value stocks.

     LARGE-CAP VALUE FUNDS (Income & Growth) -- funds that invest primarily in
large companies that are considered to be undervalued relative to major stock
indexes.

     SMALL-CAP CORE FUNDS (Small Cap Quantitative) -- funds that invest
primarily in small companies and strike a balance between growth and value
stocks.

Glossary
--------------------------------------------------------------------------------

RETURNS

* TOTAL RETURN figures show the overall percentage change in the value of a
hypothetical investment in the fund and assume that all of the fund's
distributions are reinvested.

* AVERAGE ANNUAL RETURNS illustrate the annually compounded returns that would
have produced the fund's cumulative total returns if the fund's performance had
been constant over the entire period. Average annual returns smooth out
variations in a fund's return; they are not the same as fiscal year-by-year
results. For fiscal year-by-year total returns, please refer to the "Financial
Highlights" on pages 36-43.

PORTFOLIO STATISTICS

* NUMBER OF COMPANIES --the number of different companies held by the fund on a
given date.

* DIVIDEND YIELD --a percentage return calculated by dividing the fund's
dividend distributions over the past year by its current share price.

* PRICE/EARNINGS (P/E) RATIO --a stock value measurement calculated by dividing
a company's stock price by its earnings per share, with the result expressed as
a multiple instead of as a percentage. (Earnings per share are calculated by
dividing the after-tax earnings of a corporation by its outstanding shares.)

* PORTFOLIO TURNOVER --the percentage of the fund's investment portfolio that is
replaced during a given time period, usually a year. Actively managed portfolios
tend to have higher turnover than passively managed portfolios such as index
funds.

* EXPENSE RATIO --the operating expenses of the fund, expressed as a percentage
of average net assets. Shareholders pay an annual fee to the investment manager
for investment advisory and management services. The expenses and fees are
deducted from fund income, not from each shareholder account. (See Note 2 in the
Notes to Financial Statements.)

EQUITY TERMS

* BLUE CHIP STOCKS -- stocks of the most established companies in American
industry. They are generally large, fairly stable companies that have
demonstrated consistent earnings and usually have long-term growth potential.
Examples include General Electric and Coca-Cola.

* GROWTH STOCKS -- stocks of companies that have experienced above-average
earnings growth and appear likely to continue such growth. These stocks often
sell at high P/E ratios. Examples can include the stocks of technology,
healthcare, and consumer goods companies.

* VALUE STOCKS -- stocks that are purchased because they are relatively
inexpensive. These stocks are typically characterized by low P/E ratios.

* LARGE-CAPITALIZATION ("LARGE-CAP") STOCKS -- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) of more
than $8.7 billion. This is Lipper's market-capitalization breakpoint as of June
30, 2000, although it may be subject to change based on market fluctuations. The
Dow Jones Industrial Average and the S&P 500 are representative indexes of
large-cap stock performance.

* MEDIUM-CAPITALIZATION ("MID-CAP") STOCKS -- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) between
$2.3 billion and $8.7 billion. This is Lipper's market-capitalization breakpoint
as of June 30, 2000, although it may be subject to change based on market
fluctuations. The S&P 400 and Russell 2500 are representative of mid-cap stock
performance.

* SMALL-CAPITALIZATION ("SMALL-CAP") STOCKS -- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) of less
than $2.3 billion. This is Lipper's market-capitalization breakpoint as of June
30, 2000, although it may be subject to change based on market fluctuations. The
S&P 600 and the Russell 2000 are representative of small-cap stock performance.

FUND CLASSIFICATIONS

    Please be aware that the fund's category may change over time. Therefore, it
is important that you read a fund's prospectus or fund profile carefully before
investing to ensure its objectives, policies, and risk potential are consistent
with your needs.

INVESTMENT OBJECTIVE

    The investment objective may be based on the fund's objective as stated in
its prospectus or fund profile, or the fund's categorization by independent
rating organizations based on its management style.

* CAPITAL PRESERVATION -- offers taxable and tax-free money market funds for
relative stability of principal and liquidity.

* INCOME -- offers funds that can provide current income and competitive yields,
as well as a strong and stable foundation and generally lower volatility levels
than stock funds.

* GROWTH & INCOME -- offers funds that emphasize both growth and income provided
by either dividend-paying equities or a combination of equity and fixed-income
securities.

* GROWTH -- offers funds with a focus on capital appreciation and long-term
growth, generally providing high return potential with corresponding high
price-fluctuation risk.

RISK

    The classification of funds by risk category is based on quantitative
historical measures as well as qualitative prospective measures. It is not
intended to be a precise indicator of future risk or return levels. The degree
of risk within each category can vary significantly, and some fund returns have
historically been higher than more aggressive funds or lower than more
conservative funds.

* CONSERVATIVE -- these funds generally provide lower return potential with
either low or minimal price-fluctuation risk.

* MODERATE -- these funds generally provide moderate return potential with
moderate price-fluctuation risk.

* AGGRESSIVE -- these funds generally provide high return potential with
corresponding high price-fluctuation risk.

conservative, dependable way to invest for a specific time horizon.

     The first half of 2000 was a period of exceptional volatility in the
financial markets, as strong economic growth ran up against coordinated interest
rate increases by world central banks. Prices for precious metals and other
commodities were further buffeted by concerns about supply and demand.

     The performance of natural resources-related stocks was widely divergent,
while worries about the execution of some high-profile mergers weighed on gold
company shares. In times such as these, it pays to recall that American Century
Global Gold and Global Natural Resources are intended to play a small but
important role in diversifying a larger, long-term investment portfolio.

     Despite the challenging environment, American Century Global Gold and
Global Natural Resources outperformed their respective benchmarks, though our
more pure-play management approach meant they lagged their Lipper category
averages. Our investment professionals review the period and the funds'
performance in more detail beginning on page 3.

     On the corporate front, we're proud to announce that American Century's
fund performance reports, like this one, earned the Communications Seal from
DALBAR, Inc., an independent financial services research firm. DALBAR commended
us for meeting investors' needs with an attractive document that's easy to read
and understand.

     We're also pleased to provide investors with two new investment tools. Fund
Advisor,(1) an online advice engine, is designed to give impartial guidance in
choosing the right no-load mutual funds to meet your financial goals.(2) And
American Century is the program manager for Learning Quest,(SM) an educational
savings program launched by the state of Kansas on July 1 that allows parents to
invest tax-deferred to meet higher education costs. The summer issue of the
American Century investor newsletter provides more details on these tools.

     As always, we appreciate your continued confidence in American Century.

Sincerely,

Report Highlights
--------------------------------------------------------------------------------

MARKET PERSPECTIVE

Gold

*   Gold's price was little changed in the first six months of the year,
    finishing at about $290 an ounce.

*   One negative for gold was more aboveground supply--world central bank sales
    and hedging activity by gold producers continued apace.

*   While supply increased, demand rose modestly thanks to better global
    economic growth.

*   Gold stocks finished lower because of negative sentiment after many
    companies mishandled their hedging activity late last year.

*   By region, the low-cost North American gold producers held up better than
    African and Australian companies.

Natural Resources

*   Commodity prices diverged sharply in the first half of 2000 as energy prices
    rose while most basic materials were flat.

*   Energy prices were helped by OPEC's decision to cut back its output, as well
    as by better demand and low inventories.

*   Higher oil prices meant positive returns for energy stocks. Integrated oil
    companies posted mildly positive returns, while small oil exploration and
    service stocks performed best because they're more closely tied to the price
    of oil.

*   Basic materials shares performed poorly. Investors worried that higher
    interest rates would slow economic growth and hurt corporate profits.

GLOBAL GOLD

*   Global Gold produced negative returns, in line with the broader gold market.
    The fund beat its benchmark but lagged its Lipper group.

*   The portfolio outdid its benchmark because of some of our company weightings
    relative to the index, and because we kept about 5% of assets in more liquid
    (easier to buy and sell) platinum and palladium companies.

*   Several high-profile mergers failed to boost the gold sector--investors
    worried that consolidation would mean much lower production costs, and
    ultimately lower prices for the underlying metal.

*   Gold seems locked in a trading range between about $260 and $300 an ounce.
    However, gold company shares look like they currently have more upside than
    downside.

GLOBAL NATURAL RESOURCES

*   Global Natural Resources beat its benchmark, though the fund underperformed
    its Lipper group.

*   The key reason the fund beat the benchmark is that the portfolio was
    overweight energy and underweight basic materials relative to the index.

*   The stocks that had the biggest positive impact on performance were in the
    oil services sector, while those that hurt returns most were steel and paper
    company shares.

*   We believe economic growth should remain strong through the end of the year,
    which would create a positive backdrop for natural resources-related shares.

Market Perspective from Mark Mallon
--------------------------------------------------------------------------------
[photo of Mark Mallon]

Mark Mallon, head of growth and income equity, specialty, and asset allocation
funds at American Century

GOLD OVERVIEW

     Gold bullion finished the first half of 2000 about where it began the
year--at around $290 an ounce. While gold's price was basically flat, gold
company stocks finished lower.

BULLION LITTLE CHANGED

     A key reason gold languished was that inflation remained largely in check.
The Federal Reserve and other world central banks so far have been successful at
raising interest rates to keep a lid on inflation. That's bad for gold because
its price typically rises in an inflationary environment, or one where "real"
interest rates are 0% or less. ("Real" rates equal nominal interest rates minus
the inflation rate.) But with inflation running at only about 3% annually in the
U.S. and Treasury bond yields around 6% or more, we're nowhere near zero real
rates.

     Gold sales by world central banks again weighed on the precious metal.
Austria, Canada, the Netherlands, and the U.K. were among the more prominent
central banks to sell gold during the six months. Further blows to the market
were reports that France and Switzerland intended to sell a portion of their
gold reserves.

     In addition, gold producers increased their hedging activity. Central bank
sales and hedging by gold producers meant more aboveground supply, which hurt
gold prices.

     While supply increased, demand rose modestly. According to the World Gold
Council, gold demand rose 1% in the first quarter of 2000 (the latest period for
which figures are available). Total demand for gold is derived from two sources:
fabrication (gold used in jewelry, for example) and investment. Fabrication
demand rose sharply thanks to better global economic growth. Investment demand
for gold fell, however, after peaking late last year because of Y2K concerns.

GOLD STOCKS LOWER

     While the price of gold bullion was little changed, gold shares did not
fare as well. Sentiment surrounding these stocks has remained negative since
late 1999, when many gold companies failed to benefit from a rally in gold's
price because they mismanaged their hedging activity. Being heavily hedged meant
many companies didn't participate fully in gold's brief rally.

     By region, North American gold shares held up best. In general, North
American gold companies have lower-than-average production costs, so they tend
to perform better than their competitors when gold's price is relatively low.

     African and Australian gold producers fared worse than the market as a
whole. These companies generally have high production costs, which crimped their
profitability with gold trading below $300 an ounce.

     In addition, Australian-area gold companies include those in Papua New
Guinea and Indonesia, where labor unrest created an unfavorable environment for
these stocks.

COMMODITIES

     Commodity price performance was sharply divided in the first half of 2000,
as oil prices leapt while most other commodities languished. For the six months,
the Goldman Sachs Commodities Index, which is heavily weighted toward energy,
rose almost a third. By comparison, the Commodities Research Bureau Commodities
Index was up about 10%.

     The disparity in commodity performance is starkly apparent in some of the
components of the Goldman index. For example, the Goldman Sachs Energy Index was
up almost 60%, while the Goldman Metals Index fell 4%.

     Key to the increase in prices for oil and energy-related products were
production cuts by OPEC. While OPEC was cutting back on its output, inventories
ran low because of strong demand for petroleum-based products. Less supply and
higher demand sent oil prices surging.

     Basic materials--such as paper, forest products, and nonferrous
metals--faced a more difficult environment. Prices for many of these commodities
came under pressure because of concerns that higher interest rates could mean
slower economic growth going forward.

     Base metals in particular performed surprisingly poorly despite tight
supply. A big reason for the disconnect between supply and prices is that metal
consumers are keeping smaller inventories. Without inventory building, demand
for base metals suffered.

NATURAL RESOURCES STOCKS

     As with the commodities themselves, performance for natural
resources-related stocks was mixed. Energy shares were helped to positive
returns by the big jump in oil prices, while basic materials shares lagged badly
(see the graph at left).

     Within the energy sector, the small oil service and exploration companies
generally performed best. They did better than the big international integrated
oil companies because the smaller companies are a purer play on changes in oil
prices. The big integrated companies are much more diverse, with refining and
chemical sides to their businesses.

     Natural gas stocks also posted solid gains. Strong global demand and high
energy prices fueled growth in the sector. In addition, these shares reaped the
rewards from investors' shift from growth to more traditional value stocks in
March and April.

     Basic materials companies--such as papers, metals, and mining
companies--hit a rough patch in the first half of 2000 because investors were
worried that coordinated interest rate increases by world central banks would
put the brakes on global growth. The success of these companies is tied to
industrial production and commodity demand, so slower growth threatens their
profits.

     By region, shares of U.S. natural resources-related companies were among
the weakest performers globally, while European and Japanese companies held up
better.

Global Gold--Q&A
--------------------------------------------------------------------------------
[photo of Bill Martin]

     An interview with Bill Martin, a portfolio manager on the Global Gold fund
investment team.

HOW DID GLOBAL GOLD PERFORM DURING THE SIX MONTHS ENDED JUNE 30, 2000?

     The portfolio finished lower, tracking the broader gold market. For the
first half of the year, Global Gold returned -15.20%, while the 34 gold-oriented
funds tracked by Lipper Inc. had an average return of -14.65%.* By comparison,
the fund's custom benchmark--which is about two-thirds North American, 20% or so
African, and about 10% Australian gold stocks--returned -16.25%. (See the
previous page for additional performance comparisons.)

HOW DO YOU EXPLAIN GLOBAL GOLD'S PERFORMANCE RELATIVE TO ITS BENCHMARK AND THE
LIPPER GROUP?

     First, let's define some terms. Our benchmark reflects the state of the
entire gold market; meanwhile, the Lipper group includes funds that invest
two-thirds of their assets or more in gold companies. That means there's a lot
of room for the funds in the Lipper group to hold other, non-gold stocks.

     Because we manage Global Gold relative to the benchmark, the portfolio is
more of a pure play on the gold market than the funds in its Lipper group. As a
result, we often underperform when gold stocks fall, while we tend to do better
when gold shares rise.

OKAY, SO GLOBAL GOLD TYPICALLY LAGS THE LIPPER GROUP WHEN GOLD STOCKS DECLINE
AND OUTPERFORMS WHEN GOLD SHARES RISE. BUT HOW DID THE FUND MANAGE TO BEAT  ITS
BENCHMARK?

     We made good decisions on some of our company weightings, and we continued
to keep a small portion of assets in near-gold stocks, such as platinum,
palladium, and diamond companies. Platinum and palladium stocks outperformed
gold shares, so our modest position in these names helped Global Gold beat its
benchmark.

     But we should be clear: we're still committed to delivering an investment
that moves in line with gold. As a result, we're limiting the near-gold slice of
the portfolio to around 5% of assets and holding only stocks that have a very
high correlation to gold shares.

WHAT'S THE ADVANTAGE OF HOLDING A SMALL NUMBER OF NEAR-GOLD STOCKS?

     We're holding these stocks because they're more liquid than gold company
shares. That means they're easier to buy and sell, so holding a modest position
in these names helps us save on transaction costs. We think that allows us to
manage cash flows without racking up big trading costs while still providing our
shareholders a nearly pure play on gold.

YOU ALSO MENTIONED THAT SOME INDIVIDUAL GOLD NAMES HELPED THE FUND BEAT ITS
BENCHMARK. CAN YOU GIVE AN EXAMPLE?

     We were overweight Barrick Gold relative to the benchmark, which helped our
performance because the stock had a positive return for the six months. Barrick

Global Gold--Q&A
--------------------------------------------------------------------------------
                                                                    (Continued)

performed relatively poorly last year, falling more than 25% in the last few
months of 1999. Because it fell so far so fast, investors now seem to view the
stock as a better value.

     Barrick is particularly attractive because it has the lowest production
costs in the industry to go along with sophisticated hedging strategies. In
addition, the stock benefited from positive developments at new mines in Africa
and South America.

BUT MOST GOLD STOCKS FELL. HOW ABOUT AN EXAMPLE OF A GOLD STOCK THAT DECLINED?

     Newmont Mining, our second-largest holding, is a good example of a stock
that fell but still held up better than the market as a whole. We like Newmont
because it's another of those large, low-cost, North American producers. But
unlike Barrick, Newmont hedges little of its gold production. Newmont also had
difficulty at its mine in Indonesia, where labor unrest and political problems
have plagued operations.

     To its credit, Newmont tried to add value for shareholders by acquiring
gold producer Battle Mountain. The hope is that the deal will add to Newmont's
bottom line by promoting efficiencies and boosting its gold output.

WEREN'T THERE SEVERAL HIGH-PROFILE MERGERS IN THE SECTOR IN RECENT MONTHS?

     Yes, gold's low price is forcing consolidation on the entire industry.
Canadian concern Franco Nevada Mining committed to buy South African company
Gold Fields Ltd. The union would create one of the top gold producers in the
world. In addition, Anglogold acquired Australian company Acacia, while Normandy
Mining bought a controlling interest in TVX Gold.

     These moves failed to boost the sector, however. Analysts question the
Franco-Gold Fields combination because they don't see obvious synergies or cost
savings from the deal. Instead, they view it largely as a diversification play.
What's more, there's worry that the current round of merger mania might signal
dramatically lower production costs for the industry as a whole.

LOWER PRODUCTION COSTS SOUND LIKE A  GOOD THING. HOW CAN THAT BE VIEWED AS  A
NEGATIVE FOR GOLD?

     The downside risk is that lower production costs ultimately put pressure on
the price of gold itself. Here's how it works: individual companies benefit when
they lower their production costs faster than the rest of the industry. Lower
costs allow them to book more profits on the sale of gold. But that encourages
them to boost production or borrow gold from dealers and sell it forward. That
argues for more supply and lower prices.

     And remember, we're talking about an entire industry consolidating to cut
costs. The decline in production costs in recent years largely explains why gold
supply has increased even as the metal's price declined.

HOW COULD ALL THESE MERGERS BENEFIT THE GOLD MARKET?

     The upside to more efficient gold companies operating at lower production
costs would be that high-cost producers will eventually shut down their most
expensive mines or face going out of business entirely. Ultimately, that could
mean less supply of gold, which would lead you to expect higher prices at some
point.

                                                                    (Continued)

     Another potential positive for gold is that companies have cut their
exploration budgets significantly in recent years. That means they're not
putting much effort into replacing all the gold they're pulling out of the
ground. Here again, that would seem to argue for less supply and a better
pricing situation down the line.

WHAT'S YOUR OUTLOOK FOR GOLD BULLION?

     After mine supply, probably the biggest factor for gold is how global
economic growth relates to demand. The global economy continues to improve,
which should boost demand for gold. In addition, gold fabrication demand often
gets a boost in the third quarter prior to the holiday season.

     We also think the market's largely over the shock of world central bank
gold sales. But despite some of these positives, it's hard to see gold breaking
out of its current range--between $260 and $300 an ounce--anytime soon.

WHAT'S YOUR OUTLOOK FOR GOLD SHARES AND THE FUND?

     We're surprisingly positive on gold shares going forward for a couple
reasons. First, we think it's increasingly likely that the Federal Reserve is
done raising interest rates. Higher rates were one factor keeping inflation--and
gold's price--in check the last year or so. Second, from a risk-return
standpoint, gold shares look like they have much more upside than downside with
gold at current prices. If we're right that gold shares are near a bottom, they
could perform well if gold's price improves.

     In terms of the fund, we plan to try to position the portfolio to benefit
from any bounce in the price of gold.

Global Natural Resources--Q&A
--------------------------------------------------------------------------------
[photo of Joe Sterling]

     An interview with Joe Sterling, a portfolio manager on the Global Natural
Resources fund investment team.

HOW DID GLOBAL NATURAL RESOURCES PERFORM DURING THE FIRST HALF OF 2000?

     The fund's return was basically flat, reflecting the schizophrenic
performance of natural resources-related stocks generally. Returns for energy
stocks were positive but widely divergent, while basic materials stocks
performed very poorly (see page 4).

     On a positive note, Global Natural Resources' 0.47% return beat the -2.23%
return of its custom benchmark.* In addition, the fund outperformed the S&P 500
stock index, which returned -0.42%. That's important because the portfolio is
intended to help investors diversify a portfolio of domestic equities. However,
the fund lagged the 13.34% average return of the 59 natural resource funds
tracked by Lipper (see the previous page for additional performance
comparisons).

WHY DID GLOBAL NATURAL RESOURCES BEAT ITS BENCHMARK BUT TRAIL THE LIPPER GROUP?

     We manage Global Natural Resources against a custom benchmark that's based
on the companies in the Basic Materials and Energy sectors of the Dow Jones
World Stock Index. So the key to understanding the fund's relative performance
is sector weightings.

     Global Natural Resources outpaced its benchmark because we were slightly
overweight in energy stocks and underweight basic materials shares. But when
comparing the fund with the Lipper group, keep in mind that we try to deliver
returns representative of the entire market for natural resources-related
stocks. That can limit our return relative to the Lipper group when a small
segment of the market--such as oil service and exploration stocks--post
exceptional returns for a short period.

HOW DID YOU STRUCTURE THE FUND'S  ENERGY HOLDINGS?

     We were neutral to slightly underweight the big, integrated international
oil companies. But because they make up such a large piece of our benchmark,
these companies account for seven of our top 10 holdings (see the table on page
12).

     Returns for the international integrated companies were less than stellar.
For the six months, Standard & Poor's international integrated oil company
index--which includes Chevron, Exxon Mobil, Royal Dutch Petroleum, and
Texaco--had a total return of about 2%. With oil prices so high, these companies
produced excellent earnings, but many investors were reluctant to buy these
shares because they felt oil prices had peaked and were likely to fall going
forward.

     Instead, we were overweight the smaller oil service and exploration
companies, which did very well because they're more sensitive to changes in the
price of oil. For the six months, oil service shares jumped more than 33%.

--------------------------------------------------------------------------------
                                                                    (Continued)

CAN YOU GIVE AN EXAMPLE OF SOME OF THESE OIL SERVICE AND OTHER ENERGY STOCKS
THAT CONTRIBUTED SIGNIFICANTLY TO PERFORMANCE?

     A great example of an oil service company we like is Schlumberger. It
provides tools, testing and monitoring equipment, and other services to
companies in the oil, gas, and utility sectors. Its stock soared more than 70%
during the first half of the year.

     Another of our top-10 holdings that performed very well is El Paso Energy.
Its proposed merger with Coastal Corporation would result in one of the largest
natural gas distributors and suppliers in the U.S. News of the impending merger
drove share prices for both companies higher.

ON THE OTHER HAND, BASIC MATERIALS SHARES PERFORMED POORLY. WHICH STOCKS IN
PARTICULAR DETRACTED FROM FUND PERFORMANCE?

     Within the basic materials group, we were slightly overweight paper stocks.
Our bet on paper and forest products detracted from performance--papers were
down more than 20% for the six months. International Paper--a bellwether paper
stock--saw its share price hit a five-year low during the second quarter.
Weyerhaeuser was another paper and forest products company that appeared on our
list of worst performers.

WERE THERE ANY PLAYS YOU MADE WITHIN BASIC MATERIALS THAT ENHANCED FUND
PERFORMANCE?

     There were few winners among basic materials shares on an absolute return
basis; however, we helped performance relative to the index by being underweight
steel companies. Steel prices actually held up relatively well, but the shares
suffered from the same factors that hurt other basic materials stocks.

     Investors simply took a wait-and-see approach toward many of these stocks
because of interest rate increases by world central banks. The worry was that
attempts by central banks to pre-empt inflation might forestall economic growth
and pull the rug out from under these shares. Examples of some of the steel
producers in the portfolio are Thyssen Krupp in Germany and Nippon Steel in
Japan.

YOU OFTEN SAY GLOBAL GROWTH IS KEY TO THE FUND'S SUCCESS. WHAT'S YOUR OUTLOOK
FOR THE GLOBAL ECONOMY IN THE SECOND HALF OF THE YEAR?

     We think the global economy is set to chug along quite nicely through the
end of the year. Indeed, J.P. Morgan analysts estimate that the first quarter
saw the fastest rate of global growth in more than a dozen years. As a result,
they've ramped up their growth projections for the rest of 2000 (see the chart
on the following page).

     That rapid growth led the Federal Reserve to raise interest rates in the
U.S. Higher rates mean the U.S. economy may slow somewhat, but a recession seems
unlikely. While the U.S. will likely slow, the global economy is generally more
healthy than it's been in several years. Continued expansion in Europe and
firmer Asian economies bode well for global activity.

WHAT'S THAT OUTLOOK IMPLY FOR  COMMODITY PRICES?

     We think continued healthy economic growth and tight inventories for many
commodities make for a generally positive backdrop for prices. Of course, the
risk to this view would be if the Fed brings the U.S. economy to a screeching
halt. But in the absence of a recession, inventories of raw materials should be
further depleted to fuel global growth.

     One exception to this outlook is oil. OPEC members are talking about
increasing production to bring oil's price back down to around $25 a barrel.
This would help curb inflation and promote sustainable economic growth.

WHAT'S YOUR OUTLOOK FOR GLOBAL NATURAL RESOURCES-RELATED STOCKS?

     If we're right about the economic scenario, natural resources-related
stocks could perform well. Many stocks, most notably those in the non-ferrous
metals sector, have already seen their prices discounted for a recession in the
U.S., if not globally. If a recession fails to materialize, these stocks should
respond favorably. In addition, better commodity prices would also likely lead
to a reassessment of natural resources-related companies, which could likely
benefit their share prices.

     And despite our forecast for slightly lower oil prices, we think the
outlook for oil companies is positive. The performance of the big integrated
stars has been lackluster because investors saw the elevated price of oil as
unsustainable. A more stable--but still high--price for oil could ultimately
boost oil company stocks.

HOW DO YOU PLAN TO POSITION GLOBAL NATURAL RESOURCES GOING FORWARD?

     We'll probably continue to favor the energy sector while modestly
underweighting basic materials shares relative to our benchmark, whose neutral
weighting is about 65% energy and 35% basic materials. Within energy, we
currently plan to emphasize oil service companies as the second half of the year
progresses. That's because we think the small- to mid-sized service stocks still
have a good upside given likely increases in capital expenditures by the major
oil companies.

Statement of Assets and Liabilities
--------------------------------------------------------------------------------

This statement breaks down the fund's ASSETS (such as securities, cash, and
other receivables) and LIABILITIES (money owed for securities purchased,
management fees, and other liabilities) as of the last day of the reporting
period. Subtracting the liabilities from the assets results in the fund's NET
ASSETS. For each class of shares, the net assets divided by shares outstanding
is the share price, or NET ASSET VALUE PER SHARE. This statement also breaks
down the fund's net assets into capital (shareholder investments) and
performance (investment income and gains/losses).

JUNE 30, 2000 (UNAUDITED)

--------------------------------------------------------------------------------
1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    ORGANIZATION -- American Century Quantitative Equity Funds (the corporation)
is registered under the Investment Company Act of 1940 (the 1940 Act) as an
open-end management investment company. Global Gold Fund (Global Gold) and
Global Natural Resources Fund (Global Natural Resources) (the funds) are two of
the six funds issued by the corporation. The funds are non-diversified under the
1940 Act. Global Gold's investment objective is to seek to realize a total
return (capital growth and dividends) consistent with investment in securities
of companies that are engaged in mining, processing, fabricating or distributing
gold or other precious metals throughout the world. Global Natural Resources'
investment objective is to seek to realize a total return consistent with
investment in companies that are engaged in the natural resources industry. The
funds invest primarily in equity securities. The following significant
accounting policies are in accordance with generally accepted accounting
principles; these policies may require the use of estimates by fund management.

    MULTIPLE CLASS -- The funds are authorized to issue two classes of shares:
the Investor Class and the Advisor Class. The two classes of shares differ
principally in their respective shareholder servicing and distribution expenses
and arrangements. All shares of the funds represent an equal pro rata interest
in the assets of the class to which such shares belong, and have identical
voting, dividend, liquidation and other rights and the same terms and
conditions, except for class specific expenses and exclusive rights to vote on
matters affecting only individual classes.

    SECURITY VALUATIONS -- Portfolio securities traded primarily on a principal
securities exchange are valued at the last reported sales price, or at the mean
of the latest bid and asked prices where no last sales price is available.
Securities traded over-the-counter are valued at the mean of the latest bid and
asked prices or, in the case of certain foreign securities, at the last reported
sales price, depending on local convention or regulation. When valuations are
not readily available, securities are valued at fair value as determined in
accordance with procedures adopted by the Board of Directors.

    SECURITY TRANSACTIONS -- Security transactions are accounted for as of the
trade date. Net realized gains and losses are determined on the identified cost
basis, which is also used for federal income tax purposes.

    INVESTMENT INCOME -- Dividend income less foreign taxes withheld (if any) is
recorded as of the ex-dividend date. Interest income is recorded on the accrual
basis and includes accretion of discounts and amortization of premiums.

    FOREIGN CURRENCY TRANSACTIONS -- All assets and liabilities initially
expressed in foreign currencies are translated into U.S. dollars at prevailing
exchange rates at period end. Purchases and sales of investment securities,
dividend and interest income, and certain expenses are translated at the rates
of exchange prevailing on the respective dates of such transactions. For assets
and liabilities, other than investments in securities, net realized and
unrealized gains and losses from foreign currency translations arise from
changes in currency exchange rates.

    Net realized and unrealized foreign currency exchange gains or losses
occurring during the holding period of investment securities are a component of
realized gain (loss) on investments and unrealized appreciation (depreciation)
on investments, respectively.

    FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS -- The funds may enter into
forward foreign currency exchange contracts to facilitate transactions of
securities denominated in a foreign currency or to hedge the fund's exposure to
foreign currency exchange rate fluctuations. The net U.S. dollar value of
foreign currency underlying all contractual commitments held by the funds and
the resulting unrealized appreciation or depreciation are determined daily using
prevailing exchange rates. The funds bear the risk of an unfavorable change in
the foreign currency exchange rate underlying the forward contract.
Additionally, losses may arise if the counterparties do not perform under the
contract terms.

    REPURCHASE AGREEMENTS -- The funds may enter into repurchase agreements with
institutions that the funds' investment manager, American Century Investment
Management, Inc. (ACIM), has determined are creditworthy pursuant to criteria
adopted by the Board of Directors. Each repurchase agreement is recorded at
cost. The funds require that the collateral, represented by securities, received
in a repurchase transaction be transferred to the fund's custodian in a manner
sufficient to enable the funds to obtain those securities in the event of a
default under the repurchase agreement. ACIM monitors, on a daily basis, the
securities transferred to ensure the value, including accrued interest, of the
securities under each repurchase agreement is greater than amounts owed to the
funds under each repurchase agreement.

    JOINT TRADING ACCOUNT -- Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the funds, along with other registered
investment companies having management agreements with ACIM, may transfer
uninvested cash balances into a joint trading account. These balances are
invested in one or more repurchase agreements that are collateralized by U.S.
Treasury or Agency obligations.

    INCOME TAX STATUS -- It is the funds' policy to distribute all net
investment income and net realized gains to shareholders and to otherwise
qualify as a regulated investment company under the provisions of the Internal
Revenue Code. Accordingly, no provision has been made for federal or state
income taxes.

    DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded
on the ex-dividend date. Distributions from net investment income are declared
and paid semiannually. Distributions from net realized gains are declared and
paid annually.

    The character of distributions made during the year from net investment
income or net realized gains may differ from their ultimate characterization for
federal income tax purposes. Those differences reflect the differing character
of certain income items and net realized gains and losses for financial
statement and tax purposes and may result in reclassification among certain
capital accounts.

                                                                    (Continued)

JUNE 30, 2000 (UNAUDITED)

    At December 31, 1999, Global Gold had accumulated net realized capital loss
carryovers for federal income tax purposes of $132,062,715 (expiring 2005
through 2007) which may be used to offset future taxable gains.

    For the two month period ended December 31, 1999, Global Gold and Global
Natural Resources incurred net capital and currency losses of $4,834,031 and
$30,649, respectively. The funds have elected to treat such losses as having
been incurred in the following fiscal year.

    ADDITIONAL INFORMATION -- Funds Distributor, Inc. (FDI) is a distributor of
the corporation. Certain officers of FDI are also officers of the corporation.

--------------------------------------------------------------------------------
2.  TRANSACTIONS WITH RELATED PARTIES

    The corporation has entered into a Management Agreement with ACIM, under
which ACIM provides the funds with investment advisory and management services
in exchange for a single, unified management fee per class. The Agreement
provides that all expenses of the funds, except brokerage commissions, taxes,
portfolio insurance, interest, fees and expenses of the directors who are not
considered "interested persons" as defined in the 1940 Act (including counsel
fees) and extraordinary expenses, will be paid by ACIM. The fee is calculated
daily and paid monthly. It consists of an Investment Category Fee based on the
average net assets of the funds in a specific fund's investment category and a
Complex Fee based on the average net assets of all the funds managed by ACIM.
The rates for the Investment Category Fee range from 0.3380% to 0.5200% and the
rates for the Complex Fee (Investor Class) range from 0.2900% to 0.3100%. The
Advisor Class is 0.2500% less at each point within the Complex Fee range. For
the six months ended June 30, 2000, the effective annual Investor Class
management fee was 0.67% for Global Gold and Global Natural Resources.

    The Board of Directors has adopted the Advisor Class Master Distribution and
Shareholder Services Plan (the plan), pursuant to Rule 12b-1 of the 1940 Act.
The plan provides that the funds will pay ACIM an annual distribution fee equal
to 0.25% and service fee equal to 0.25%. The fees are computed daily and paid
monthly based on the Advisor Class's average daily closing net assets during the
previous month. The distribution fee provides compensation for distribution
expenses incurred by financial intermediaries in connection with distributing
shares of the Advisor Class including, but not limited to, payments to brokers,
dealers, and financial institutions that have entered into sales agreements with
respect to shares of the funds. The service fee provides compensation for
shareholder and administrative services rendered by ACIM, its affiliates or
independent third party providers. Fees incurred under the plan during the six
months ended June 30, 2000, were $50 for Global Gold and $106 for Global Natural
Resources.

    Effective March 13, 2000, American Century Investment Services, Inc. (ACIS),
became a distributor of the corporation.

    Certain officers and directors of the corporation are also officers and/or
directors, and, as a group, controlling stockholders of American Century
Companies, Inc., the parent of the corporation's investment manager, ACIM, a
distributor of the corporation, ACIS, and the corporation's transfer agent,
American Century Services Corporation.

--------------------------------------------------------------------------------
3.  INVESTMENT TRANSACTIONS

Share Class and Retirement Account Information
--------------------------------------------------------------------------------

SHARE CLASSES

    Two classes of shares are authorized for sale by the funds: Investor Class
and Advisor Class.

    INVESTOR CLASS shareholders do not pay any commissions or other fees for
purchase of fund shares directly from American Century. Investors who buy
Investor Class shares through a broker-dealer may be required to pay the
broker-dealer a transaction fee.

    ADVISOR CLASS shares are sold through banks, broker-dealers, insurance
companies and financial advisors. Advisor Class shares are subject to a 0.50%
Rule 12b-1 service and distribution fee. Half of that fee is available to pay
for recordkeeping and administrative services, and half is available to pay for
distribution services provided by the financial intermediary through which the
Advisor Class shares are purchased. The total expense ratio of the Advisor Class
shares is 0.25% higher than the total expense ratio of the Investor Class
shares.

    Both classes of shares represent a pro rata interest in the funds and
generally have the same rights and preferences.

RETIREMENT ACCOUNT INFORMATION

    As required by law, any distributions you receive from an IRA and certain
403(b) distributions [not eligible for rollover to an IRA or to another 403(b)
account] are subject to federal income tax withholding at the rate of 10% of the
total amount withdrawn, unless you elect not to have withholding apply. If you
don't want us to withhold on this amount, you may send us a written notice not
to have the federal income tax withheld. Your written notice is valid from the
date of receipt at American Century. Even if you plan to roll over the amount
you withdraw to another tax-deferred account, the withholding rate still applies
to the withdrawn amount unless we have received a written notice not to withhold
federal income tax prior to the withdrawal.

    When you plan to withdraw, you may make your election by completing our
Exchange/Redemption form or an IRS Form W-4P. Call American Century for either
form. Your written election is valid from the date of receipt at American
Century. You may revoke your election at any time by sending a written notice to
us.

    Remember, even if you elect not to have income tax withheld, you are liable
for paying income tax on the taxable portion of your withdrawal. If you elect
not to have income tax withheld or you don't have enough income tax withheld,
you may be responsible for payment of estimated tax. You may incur penalties
under the estimated tax rules if your withholding and estimated tax payments are
not sufficient.

Background Information
--------------------------------------------------------------------------------

INVESTMENT PHILOSOPHY AND POLICIES

     American Century offers four "specialty" funds that concentrate their
holdings in specific industries or sectors of the stock market. These funds
typically respond differently than general equity funds to changing market or
economic conditions. The funds are managed to provide a broad representation of
the respective industries. Due to the limited focus of these funds, they may
experience greater volatility than funds with a broader investment strategy.
They are not intended to serve as a complete investment program by themselves.
International investing also involves special risks, such as political
instability and currency fluctuations.

     GLOBAL GOLD seeks to realize a total return consistent with investment in
securities of companies that are engaged in mining, processing, fabricating, or
distributing gold or other precious metals throughout the world.

     GLOBAL NATURAL RESOURCES seeks to realize a total return consistent with
investment in companies that are engaged in the natural resources industries.

COMPARATIVE INDICES

     The following indices are used in the report for fund performance
comparisons. They are not investment products available for purchase.

     The GLOBAL GOLD FUND BENCHMARK was the Benham North American Gold Equities
Index from inception through February 1996. From March 1996 through December
1997, the benchmark was the FT-SE Gold Mines Index. Since January 1998, the
benchmark has been a proprietary index intended to reflect the entire gold
market.

     The FT-SE(reg.tm) GOLD MINES INDEX(1) consists of 31 gold mining companies
in five countries and is considered a broad measure of the worldwide gold
equities market.

     The DOW JONES WORLD STOCK INDEX(2) (DJWSI), created by the editors of The
Wall Street Journal, consists of 2,800 stocks in 29 countries and is divided
into nine broad market sectors. We created the GLOBAL NATURAL RESOURCES FUND'S
BENCHMARK index using the companies represented in two of these sectors--Basic
Materials and Energy. We altered the Basic Materials sector to exclude chemical
companies because they do not stockpile natural resources.

     The MORGAN STANLEY WORLD STOCK INDEX (MSCI) is a widely followed group of
stocks from 22 different countries including the U.S. and Canada.

LIPPER RANKINGS

     LIPPER INC. is an independent mutual fund ranking service that groups funds
according to their investment objectives. Rankings are based on average annual
returns for each fund in a given category for the periods indicated.

     The Lipper categories for Global Gold and Global Natural Resources are:

     GOLD-ORIENTED FUNDS (Global Gold)--funds that invest at least 65% of their
assets in shares of gold mines, gold-oriented mining finance houses, gold coins
or bullion.

     NATURAL RESOURCES FUNDS (Global Natural Resources)--funds that invest at
least 65% of their assets in natural resources stocks.

(1)  The FT-SE Gold Mines Index is calculated by FT-SE International Limited in
     conjunction with the Institute of Actuaries. The FT-SE Gold Mines Index is
     a trademark of the London Stock Exchange Limited and the Financial Times
     Ltd. and is used by FT-SE International Limited under license. FT-SE
     International Limited does not sponsor, endorse, or promote the fund.

Glossary
--------------------------------------------------------------------------------

RETURNS

* TOTAL RETURN figures show the overall percentage change in the value of a
hypothetical investment in the fund and assume that all of the fund's
distributions are reinvested.

* AVERAGE ANNUAL RETURNS illustrate the annually compounded returns that would
have produced the fund's cumulative total returns if the fund's performance had
been constant over the entire period. Average annual returns smooth out
variations in a fund's return; they are not the same as fiscal year-by-year
results. For fiscal year-by-year total returns, please refer to the "Financial
Highlights" on pages 22-25.

PORTFOLIO STATISTICS

* NUMBER OF COMPANIES -- the number of different companies held by a fund on a
given date.

* PORTFOLIO TURNOVER -- the percentage of a fund's investment portfolio that is
replaced during a given time period, usually a year. Actively managed portfolios
tend to have higher turnover than passively managed portfolios such as index
funds.

* EXPENSE RATIO -- the operating expenses of the fund, expressed as a percentage
of average net assets. Shareholders pay an annual fee to the investment manager
for investment advisory and management services. The expenses and fees are
deducted from fund income, not from each shareholder account. (See Note 2 in the
Notes to Financial Statements.)

TYPES OF STOCKS

* LARGE-CAPITALIZATION ("LARGE-CAP") STOCKS -- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) of more
than $8.7 billion. This is Lipper's market-capitalization breakpoint as of June
30, 2000, although it may be subject to change based on market fluctuations. The
Dow Jones Industrial Average and the S&P 500 are representative indexes of
large-cap stock performance.

* MEDIUM-CAPITALIZATION ("MID-CAP") STOCKS -- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) between
$2.3 billion and $8.7 billion. This is Lipper's market-capitalization breakpoint
as of June 30, 2000, although it may be subject to change based on market
fluctuations. The S&P 400 and Russell 2500 are representative of mid-cap stock
performance.

* SMALL-CAPITALIZATION ("SMALL-CAP") STOCKS -- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) of less
than $2.3 billion. This is Lipper's market-capitalization breakpoint as of June
30, 2000, although it may be subject to change based on market fluctuations. The
S&P 600 and the Russell 2000 are representative of small-cap stock performance.

FUND CLASSIFICATIONS

    Please be aware that the fund's category may change over time. Therefore, it
is important that you read a fund's prospectus or fund profile carefully before
investing to ensure its objectives, policies, and risk potential are consistent
with your needs.

INVESTMENT OBJECTIVE

    The investment objective may be based on the fund's objective as stated in
its prospectus or fund profile, or the fund's categorization by independent
rating organizations based on its management style.

* CAPITAL PRESERVATION -- offers taxable and tax-free money market funds for
relative stability of principal and liquidity.

* INCOME -- offers funds that can provide current income and competitive yields,
as well as a strong and stable foundation and generally lower volatility levels
than stock funds.

* GROWTH & INCOME -- offers funds that emphasize both growth and income provided
by either dividend-paying equities or a combination of equity and fixed-income
securities.

* GROWTH -- offers funds with a focus on capital appreciation and long-term
growth, generally providing high return potential with corresponding high
price-fluctuation risk.

RISK

    The classification of funds by risk category is based on quantitative
historical measures as well as qualitative prospective measures. It is not
intended to be a precise indicator of future risk or return levels. The degree
of risk within each category can vary significantly, and some fund returns have
historically been higher than more aggressive funds or lower than more
conservative funds.

* CONSERVATIVE -- these funds generally provide lower return potential with
either low or minimal price-fluctuation risk.

* MODERATE -- these funds generally provide moderate return potential with
moderate price-fluctuation risk.

* AGGRESSIVE -- these funds generally provide high return potential with
corresponding high price-fluctuation risk.

* While listed within the Income investment objective, the Target funds do not
pay current dividend income. Income dividends are distributed once a year in
December. The Target funds are listed in all three risk categories due to the
dramatic price volatility investors may experience during certain market
conditions. If held to their target dates, however, they can offer a
conservative, dependable way to invest for a specific time horizon.

     The first half of 2000 was an extraordinary period for the U.S. stock
market. Several major shifts in investor sentiment led to unprecedented levels
of volatility.

     The strong U.S. economy--and the accompanying rise in interest rates--was
one key factor. But so was the "New Economy"--the burgeoning technology and
telecommunications industries. Investors began to question the high valuations
of many New Economy stocks, casting doubt on their profitability and long-term
potential for success.

     As a result, the stock market grew increasingly volatile. For example, the
tech-heavy Nasdaq Composite Index lost more than 25% in a single week in early
April, then enjoyed one of its best months ever in June.

     The utilities market, because of its significant exposure to the
telecommunications industry, was affected by this volatility, as was American
Century Utilities. Our investment professionals review the period and the fund's
performance in more detail beginning on page 3.

     We're proud to announce that American Century's fund performance reports,
like this one, earned the Communications Seal from DALBAR, Inc., an independent
financial services research firm. DALBAR commended us for meeting investors'
needs with an attractive document that's easy to read and understand.

     We're also pleased to provide investors with two new investment tools. Fund
Advisor,(1) an online advice engine, is designed to give impartial guidance in
choosing the right no-load mutual funds to meet your financial goals.(2) And
American Century is the program manager for Learning Quest,(SM) an educational
savings program launched by the state of Kansas on July 1 that allows parents to
invest tax-deferred to meet higher education costs. The summer issue of the
American Century investor newsletter provides more details on these tools.

     As always, we appreciate your continued confidence in American Century.

Sincerely,
/s/James E. Stowers, Jr.                               /s/James E. Stowers III

Report Highlights
--------------------------------------------------------------------------------

GENERAL U.S. STOCK  MARKET PERSPECTIVE

*   U.S. stocks posted mixed returns in a volatile first half of 2000.

*   Small- and mid-cap stocks performed well, while large-cap stocks fell
    slightly.

*   New Economy (technology and telecommunications) stocks soared early in the
    year, plunged in April and May, and then rebounded in June.

*   During the tech sell-off, investors shifted into sectors of the market that
    had been languishing earlier in the year.

*   Economic uncertainty and the speculative fervor surrounding New Economy
    stocks caused greater day-to-day volatility.

UTILITIES MARKET PERSPECTIVE

*   Utilities stocks as a group declined in the first half of 2000, lagging the
    broader market as represented by the S&P 500.

*   The same influences that whipsawed the broader market also pushed and pulled
    utilities.

*   The rise, fall, and rebound of telecommunications stocks was a key factor.

*   So was the more steadying influence of Old Economy sectors. Electric,
    natural gas, and energy stocks generally outperformed telecom.

MANAGEMENT Q&A:  FUND PERFORMANCE

*   The fund's six-month total return surpassed that of its benchmark, but
    lagged the average return of the Lipper peer group.

*   An overweight position in energy-related companies helped the fund beat the
    benchmark.

*   The Lipper average was bolstered by funds that held a higher percentage of
    traditional electric and natural gas stocks. Those sectors outperformed
    telephones and telecom, which were the portfolio's largest weighting.

*   The portfolio's relative weightings of telecom, electric, and natural gas
    companies reflected the benchmark, which, in turn, mirrored the utilities
    industry as a whole.

*   The fund paid a bigger-than-usual income distribution on June 30, the result
    of a stock distribution by one of the portfolio's larger holdings.

MANAGEMENT Q&A: FUND OUTLOOK

*   The fund and its benchmark will likely continue to have their heaviest
    weightings in telephone and telecom stocks.

*   In the near term, utilities stock prices will be heavily influenced by the
    Federal Reserve's interest rate policy and earnings reports.

*   Overall, we plan to remain fairly neutral to the benchmark, with slightly
    overweight positions in some of our favorite electric and natural gas names.

Market Perspective from Mark Mallon

OVERVIEW

     Volatility was the watchword in the U.S. stock market during the first half
of 2000. Uncertainty about the economy, inflation, and interest rates--along
with the mood swings symptomatic of "dot-com fever"--led to wide fluctuations in
the major stock indexes.

     Large-cap stocks posted slightly negative returns, while small- and mid-cap
stocks fared better (see the table at right).

RUNNING WITH THE PACK

     After finishing 1999 at record highs, the major stock indexes stumbled out
of the gate in 2000. However, technology and telecommunications stocks--also
known as "New Economy" stocks-- continued to soar, extending their phenomenal
1999 performance. Investors discarded "Old Economy" shares and snapped up those
of dot-coms and other tech-oriented firms.

     This herd-like behavior pushed the Nasdaq Composite Index, which is
dominated by tech stocks, up by nearly 25% from the end of 1999 to its peak on
March 10, 2000. In contrast, the S&P 500 declined by 5%.

     But the speculative fervor surrounding New Economy shares contributed to
greater market volatility. Day-to-day swings of 2% or more in the major stock
indexes became increasingly common.

SHIFTING GEARS

     By March, disillusionment brought a sudden change in market sentiment. A
series of interest rate increases by the Federal Reserve threatened to cool off
the hot U.S. economy, which grew at its fastest rate in almost 16 years in the
fourth quarter of 1999. In addition, concerns surfaced about sustainability and
profitability in the New Economy, especially among Internet-related companies.

     As a result, many investors began to turn away from high-flying growth
stocks, seeking out opportunities in undervalued sectors of the market or
sitting on the sidelines entirely. Between mid-March and late May, the Nasdaq
fell 37%, including a record 25% plunge in the second week of April, while the
S&P 500 edged 1% lower.

     After this deflation of the New Economy balloon, growth stocks staged a
solid comeback in June. However, the market remained volatile amid mixed signals
about the economy's strength and future Fed interest rate policy.

SMALL WONDERS

     After being left behind in 1998 and 1999, small- and mid-cap stocks
attracted more attention during the first half of 2000, outperforming
large-company stocks. Aggressive investors were especially fond of mid-cap
stocks because they had the high growth potential of smaller companies and the
ease of trading associated with larger stocks.

Market Perspective from Mark Mallon
--------------------------------------------------------------------------------
                                                                    (Continued)

UTILITIES MARKET OVERVIEW

     In a challenging environment that battered some sectors and rewarded
others, utilities as a group declined in the first half of 2000, lagging the
broader market as represented by the S&P 500. The relatively small decline in
the overall utilities market, however, masked the volatility that occurred and
the divergence in sector performance.

     The same influences that whipsawed the broader market also pushed and
pulled utilities. The rise, fall, and rebound of telecommunications stocks was a
key factor. So was the more steadying influence of Old Economy sectors. Electric
utilities contributed generally positive performance, while natural gas and
energy companies produced some of the strongest returns. The electric, gas, and
energy sectors benefited from strong earnings reports.

TELECOM RETREATS

     The explosive performance enjoyed by telecommunications stocks during 1999
carried into the first quarter of 2000, driven largely by expanding global
demand for wireless communications. However, not all communications companies
performed well during the quarter--long distance and regional phone companies
struggled amid competitive pressures.

     The trend away from growth-oriented technology stocks, which began in March
and continued through most of the second quarter, hit telecommunications stocks
particularly hard. AT&T, Vodafone Airtouch, GTE, and Sprint all posted
significant losses for the second quarter. They suffered from the flight away
from New Economy stocks and skepticism about the future earnings potential of
long-distance phone companies.

ELECTRICS REBOUND

     Coming off their worst year in recent history, electric utility stocks,
such as Duke Energy and PG&E, staged a comeback in the first half of 2000. As
the year opened, rising interest rates and concern about competition hampered
performance. However, electric utility company shares rebounded sharply in
April, sparked by first-quarter earnings reports that beat estimates by as much
as 30%. The move from growth to value stocks in the second quarter also added to
the sector's gains.

ENERGY AND NATURAL GAS SOAR

     Energy and natural gas stocks--such as Enron and Coastal Corporation--
delivered solid gains in the first half of the year after falling victim to
rising interest rates during the second half of 1999. During the first quarter,
high energy prices and strong global demand for fuel heated the sector.

     After stumbling in April, energy and natural gas shares resumed their
ascent, driven by continued strong fuel demand matched with limited supply. This
sector also reaped the rewards from investors' shift from growth to traditional
value stocks.

Utilities--Q&A
--------------------------------------------------------------------------------
[photo of Joe Sterling]   [photo of Bill Martin]

     Based on interviews with Joe Sterling and Bill Martin, portfolio managers
on the Utilities fund investment team.

HOW DID THE UTILITIES FUND PERFORM DURING THE FIRST HALF OF 2000?

     The fund's total return was -1.22%.* That surpassed the -1.52% return of
its custom market-based benchmark, but lagged the 1.38% average return of the 95
utilities funds tracked by Lipper in the first half. However, the fund's
longer-term performance relative to its peers still looked good--American
Century Utilities continued to outperform its peer group average for the three-
and five-year periods ended June 30, 2000. (See the previous page for other fund
performance comparisons.)

WHY DID THE UTILITIES FUND LAG THE LIPPER PEER AVERAGE FOR THE FIRST HALF?

     Energy, natural gas, and electric stocks were the best-performing sectors
of the utilities market, but represented only about 40% of the fund as of June
30. Conversely, telephone and telecommunications stocks struggled and were our
biggest weighting. Funds that had larger weightings in energy, electric, and
natural gas shares, and smaller weightings in telecom tended to outperform our
portfolio.

     Of course, we believe that our telephone and telecom focus is one of the
key reasons the fund has performed relatively well against its peers over the
last five years. We think that the long-term outlook for New Economy stocks
remains bright.

WHY DID THE FUND HOLD SUCH A SEEMINGLY SMALL AMOUNT (ABOUT 29% OF THE PORTFOLIO
AS OF JUNE 30) IN ELECTRIC AND NATURAL GAS STOCKS?

     Because electric and natural gas companies have a smaller total market
capitalization than the telecom companies. We manage the fund against a custom
index that is designed to mirror the utilities industry in terms of market
capitalization. The index is made up of approximately 165 utilities stocks
consisting of about 55% telephone and communication services companies, 35%
electric and gas utilities, and the remaining 10% or so in utilities-related
service and equipment companies.

     We seek to provide performance that reflects the industry as a whole. Over
the long term, we think it's counter-productive to jump in and out of hot
sectors.

WHY DID THE FUND OUTPERFORM ITS BENCHMARK, THE CUSTOM INDEX?

     Though the portfolio was underweight in electric and natural gas utilities,
which performed well, it was overweight in energy companies (about 11.5% of the
portfolio as of June 30) that performed even better. In fact, all five
diversified energy companies listed in the fund's June 30, 2000 Schedule of
Investments (see page 9) contributed significantly to positive performance.

     Enron was far and away the top contributor to fund performance. One of our
top-ten holdings, the stock was up 45% in the first half. Other energy

                                                                    (Continued)

companies that helped returns were Coastal Corporation (up 72%), Williams
Companies (up 36%), El Paso Energy (up 31%), and Reliant Energy (up 29%). Enron
is the largest buyer and seller of natural gas in the U.S. Coastal and El Paso
benefited from their impending merger, which will create one of the largest
natural gas distributors and suppliers in the U.S.

     Energy companies benefited in general from rising fuel prices. For example,
the price of crude oil jumped more than 30% during the first half of 2000.

WHAT OTHER COMPANIES WERE TOP CONTRIBUTORS TO PERFORMANCE?

     Not surprisingly, an electric utility made the list--Calpine Corporation
(up 105%). Calpine, based in San Jose, California, is a leading independent
electric power company. It has experienced exceptional growth due to its ability
to rapidly expand its network of power plants in an environment of limited
electrical supply. Fund shareholders benefited from the fact that we
overweighted Calpine in the portfolio.

     Unlike most other telecommunications firms, U S WEST (up 19%) and Qwest (up
16%) contributed positively to performance. They merged after the markets closed
on June 30, creating a new Qwest, an $85 billion broadband Internet
communications company.

WHY DID SO MANY TELECOMMUNICATIONS STOCKS UNDERPERFORM?

     Given the sector's robust performance in 1999 and the uncertain economic
environment in 2000 as the Federal Reserve raised interest rates, it shouldn't
have been a complete surprise that telecom faltered in the first half. In
addition, one of telecom's earlier underpinnings eroded.

     Two key factors helped telecommunications stocks flourish in 1999:
technological advances and industry deregulation. Deregulation allowed companies
that wanted to provide a comprehensive bundled package of telecommunications
services--including local and long-distance phone services, online services, and
high-speed internet connections--to enter the marketplace and compete with
older, more established firms. This was good for the newcomers, but bad for some
of the more established companies, particularly phone companies.

     As a result, performance was mixed for the telecom sector during the first
quarter. Deregulation and competition put pressure on long-distance and regional
telephone companies. But while the phone companies struggled, wireless companies
continued to benefit from a growing worldwide demand for wireless
communications.

     The second quarter, however, brought negative results for the entire group.
The shift out of New Economy stocks hurt wireless companies. Concerns about
future earnings potential hampered long-distance and regional telephone
companies' performance.

WHICH TELECOMMUNICATIONS STOCKS DETRACTED MOST FROM FUND PERFORMANCE?

     It was primarily the long-distance phone companies--AT&T (down 38%), Sprint
(down 24%), GTE (down 12%), and WorldCom (down 13%). Regional phone companies
didn't do much better. For example, SBC Communications was down 11% and
BellSouth declined 9%.

Utilities--Q&A
--------------------------------------------------------------------------------
                                                                    (Continued)

WHAT FACTORS DO YOU THINK WILL HAVE THE BIGGEST IMPACT ON THE PERFORMANCE OF
UTILITY STOCKS IN THE SECOND HALF OF THE YEAR?

     One is interest rates. If rates continue to rise, utility share prices will
most likely decline. Another factor will be second-half earnings and revenue
projections. We expect earnings to be strong for gas and electric companies, at
least into the third quarter. We will monitor telecommunications companies,
keeping an eye on growth forecast numbers and any signs of decelerating
revenues.

     The regulatory environment is another key factor. We're already seeing the
impact of tougher regulatory standards in telecommunications. With the
Sprint/WorldCom merger's failure to win approval, we think merger activity in
the telecom area will decrease and the "merger premiums" on some telecom stocks
could evaporate.

WHAT DO YOU ANTICIPATE FOR THE ECONOMY AND INTEREST RATES?

     The U.S. economy appears to be achieving the "soft landing" that the
Federal Reserve hoped to engineer. This should help reduce the risk of further
interest rate increases. The fact that this is a presidential election year
should also help stabilize monetary policy in the second half of the year. The
Fed has shown a reluctance to tinker with interest rates before a presidential
election, presumably for fear of being perceived as favoring one party or
candidate over another.

GIVEN THIS ECONOMIC ENVIRONMENT, HOW  DO YOU PLAN TO MANAGE AMERICAN CENTURY
UTILITIES?

     Overall, we will take a "steady as she goes" approach. We plan to remain
fairly neutral to the fund's benchmark, with slightly overweight positions in
some of our favorite electric and gas names. Additionally, we will watch for
price declines in some of our favorite telecommunications companies as an
opportunity to add to those positions.

WHY DID THE FUND PAY SUCH A LARGE INCOME DISTRIBUTION ON JUNE 30 ($0.77 A
SHARE)?

     It was result of a stock distribution by BCE--the parent company of Bell
Canada, and a large fund holding--that was ruled to be an income distribution
and was taxable as ordinary income. During the second quarter, BCE spun off its
network equipment subsidiary, Nortel Networks. BCE distributed its 35% interest
in Nortel to its shareholders--including the Utilities fund--in the form of new
Nortel stock.

     This one-time event boosted the fund's quarterly income distribution far
above normal levels. Future quarterly income distributions should return to more
typical levels, about $0.10 a share, totaling about $0.40 a share annually.

Statement of Assets and Liabilities
--------------------------------------------------------------------------------

This statement breaks down the fund's ASSETS (such as securities, cash, and
other receivables) and LIABILITIES (money owed for securities purchased,
management fees, and other liabilities) as of the last day of the reporting
period. Subtracting the liabilities from the assets results in the fund's NET
ASSETS. For each class of shares, the net assets divided by shares outstanding
is the share price, or NET ASSET VALUE PER SHARE. This statement also breaks
down the fund's net assets into capital (shareholder investments) and
performance (investment income and gains/losses).

Notes to Financial Statements
--------------------------------------------------------------------------------

JUNE 30, 2000 (UNAUDITED)

--------------------------------------------------------------------------------
1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    ORGANIZATION -- American Century Quantitative Equity Funds (the corporation)
is registered under the Investment Company Act of 1940 (the 1940 Act) as an
open-end management investment company. Utilities Fund (the fund) is one of the
six funds issued by the corporation. The fund is diversified under the 1940 Act.
The fund seeks current income and long-term growth of capital and income. The
fund invests primarily in equity securities of companies engaged in the
utilities industry. The following significant accounting policies are in
accordance with generally accepted accounting principles; these policies may
require the use of estimates by fund management.

     MULTIPLE CLASS -- The fund is authorized to issue two classes of shares:
the Investor Class and the Advisor Class. The two classes of shares differ
principally in their respective shareholder servicing and distribution expenses
and arrangements. All shares of the fund represent an equal pro rata interest in
the assets of the class to which such shares belong, and have identical voting,
dividend, liquidation and other rights and the same terms and conditions, except
for class specific expenses and exclusive rights to vote on matters affecting
only individual classes.

    SECURITY VALUATIONS -- Portfolio securities traded primarily on a principal
securities exchange are valued at the last reported sales price, or at the mean
of the latest bid and asked prices where no sales price is available. Securities
traded over-the-counter are valued at the mean of the latest bid and asked
prices or, in the case of certain foreign securities, at the last reported sales
price, depending on local convention or regulation. When valuations are not
readily available, securities are valued at fair value as determined in
accordance with procedures adopted by the Board of Directors.

    SECURITY TRANSACTIONS -- Security transactions are accounted for as of the
trade date. Net realized gains and losses are determined on the identified cost
basis, which is also used for federal income tax purposes.

    INVESTMENT INCOME -- Dividend income less foreign taxes withheld (if any) is
recorded as of the ex-dividend date. Interest income is recorded on the accrual
basis and includes accretion of discounts and amortization of premiums.

    REPURCHASE AGREEMENTS -- The fund may enter into repurchase agreements with
institutions that the fund's investment manager, American Century Investment
Management, Inc. (ACIM), has determined are creditworthy pursuant to criteria
adopted by the Board of Directors. Each repurchase agreement is recorded at
cost. The fund requires that the collateral, represented by securities, received
in a repurchase transaction be transferred to the custodian in a manner
sufficient to enable the fund to obtain those securities in the event of a
default under the repurchase agreement. ACIM monitors, on a daily basis, the
securities transferred to ensure the value, including accrued interest, of the
securities under each repurchase agreement is greater than amounts owed to the
fund under each repurchase agreement.

    JOINT TRADING ACCOUNT -- Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the fund, along with other registered
investment companies having management agreements with ACIM, may transfer
uninvested cash balances into a joint trading account. These balances are
invested in one or more repurchase agreements that are collateralized by U.S.
Treasury and Agency obligations.

    INCOME TAX STATUS -- It is the fund's policy to distribute all net
investment income and net realized gains to shareholders and to otherwise
qualify as a regulated investment company under the provisions of the Internal
Revenue Code. Accordingly, no provision has been made for federal or state
income taxes.

    DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded
on the ex-dividend date. Distributions from net investment income are declared
and paid quarterly. Distributions from net realized gains are expected to be
declared and paid annually.

    The character of distributions made during the year from net investment
income or net realized gains may differ from their ultimate characterization for
federal income tax purposes. These differences reflect the differing character
of certain income items and net realized gains and losses for financial
statement and tax purposes and may result in reclassification among certain
capital accounts.

    For the two month period ended December 31, 1999, the fund incurred net
capital losses of $287,150. The fund has elected to treat such losses as having
been incurred in the following fiscal year.

    ADDITIONAL INFORMATION -- Funds Distributor, Inc. (FDI) is a distributor of
the corporation. Certain officers of FDI are also officers of the corporation.

2.  TRANSACTIONS WITH RELATED PARTIES

    The corporation has entered into a Management Agreement with ACIM, under
which ACIM provides the fund with investment advisory and management services in
exchange for a single, unified management fee per class. The Agreement provides
that all expenses of the fund, except brokerage commissions, taxes, portfolio
insurance, interest, fees and expenses of the directors who are not considered
"interested persons" as defined in the 1940 Act (including counsel fees) and
extraordinary expenses, will be paid by ACIM. The fee is calculated daily and
paid monthly. It consists of an Investment Category Fee based on the average net
assets of the funds in a specific fund's investment category and a Complex Fee
based on the average net assets of all the funds managed by ACIM. The rates for
the Investment Category Fee range from 0.3380% to 0.5200% and the rates for the
Complex Fee (Investor Class) range from 0.2900% to 0.3100%. The Advisor Class is
0.2500% less at each point within the Complex Fee range. For the period ended
June 30, 2000, the effective annual Investor Class management fee was 0.67%.

    The Board of Directors has adopted the Advisor Class Master Distribution and
Shareholder Services Plan (the plan), pursuant to Rule 12b-1 of the 1940 Act.
The plan provides that the fund will pay ACIM an annual distribution fee equal
to 0.25% and service fee equal to 0.25%. The fees are computed daily and paid
monthly based on the Advisor Class's average daily closing net assets during the
previous month. The distribution fee provides compensation for distribution
expenses incurred by financial intermediaries in connection with distributing
shares of the Advisor Class including, but not limited to, payments to brokers,
dealers, and financial institutions that have entered into sales agreements with
respect to shares of the fund. The service fee provides compensation for
shareholder and administrative services rendered by ACIM, its affiliates or
independent third party providers. Fees incurred by the fund under the plan for
the six months ended June 30, 2000, were $13,092.

    Effective March 13, 2000, American Century Investment Services, Inc. (ACIS),
became a distributor of the corporation.

    Certain officers and directors of the corporation are also officers and/or
directors, and, as a group, controlling stockholders of American Century
Companies, Inc., the parent of the corporation's investment manager, ACIM, a
distributor of the corporation, ACIS, and the corporation's transfer agent,
American Century Services Corporation.

    Purchases and sales of securities, excluding short-term investments, for the

Share Class and Retirement Account Information
--------------------------------------------------------------------------------

SHARE CLASSES

    Two classes of shares are authorized for sale by the fund: Investor Class
and Advisor Class.

    INVESTOR CLASS shareholders do not pay any commissions or other fees for
purchase of fund shares directly from American Century. Investors who buy
Investor Class shares through a broker-dealer may be required to pay the
broker-dealer a transaction fee.

    ADVISOR CLASS shares are sold through banks, broker-dealers, insurance
companies and financial advisors. Advisor Class shares are subject to a 0.50%
Rule 12b-1 service and distribution fee. Half of that fee is available to pay
for recordkeeping and administrative services, and half is available to pay for
distribution services provided by the financial intermediary through which the
Advisor Class shares are purchased. The total expense ratio of the Advisor Class
shares is 0.25% higher than the total expense ratio of the Investor Class
shares.

    Both classes of shares represent a pro rata interest in the funds and
generally have the same rights and preferences.

RETIREMENT ACCOUNT INFORMATION

    As required by law, any distributions you receive from an IRA and certain
403(b) distributions [not eligible for rollover to an IRA or to another 403(b)
account] are subject to federal income tax withholding at the rate of 10% of the
total amount withdrawn, unless you elect not to have withholding apply. If you
don't want us to withhold on this amount, you may send us a written notice not
to have the federal income tax withheld. Your written notice is valid from the
date of receipt at American Century. Even if you plan to roll over the amount
you withdraw to another tax-deferred account, the withholding rate still applies
to the withdrawn amount unless we have received a written notice not to withhold
federal income tax prior to the withdrawal.

    When you plan to withdraw, you may make your election by completing our
Exchange/Redemption form or an IRS Form W-4P. Call American Century for either
form. Your written election is valid from the date of receipt at American
Century. You may revoke your election at any time by sending a written notice to
us.

    Remember, even if you elect not to have income tax withheld, you are liable
for paying income tax on the taxable portion of your withdrawal. If you elect
not to have income tax withheld or you don't have enough income tax withheld,
you may be responsible for payment of estimated tax. You may incur penalties
under the estimated tax rules if your withholding and estimated tax payments are
not sufficient.

Background Information
--------------------------------------------------------------------------------

INVESTMENT PHILOSOPHY AND POLICIES

     American Century offers four "specialty" equity funds* that concentrate
their holdings in specific industries or sectors of the stock market. These
funds typically respond differently than general equity funds to changing market
or economic conditions. The funds are managed to provide a broad representation
of their respective industries.

     AMERICAN CENTURY UTILITIES seeks current income and long-term growth of
capital and income. The fund invests primarily in the stocks of companies
engaged in the utilities industry, including telecommunications services,
electricity, and natural gas.

COMPARATIVE INDICES

     The following indices are used in the report for fund performance
comparisons. They are not investment products available for purchase.

     The S&P 500 is a capitalization-weighted index of the stocks of 500
publicly traded large-capitalization companies that are considered to be leading
firms in leading industries. Created by Standard & Poor's Corporation, the index
is viewed as a broad measure of U.S. stock market performance.

     The S&P MIDCAP 400 is composed of 400 mid-capitalization stocks traded on
domestic exchanges. It is considered a broad measure of mid-sized stock
performance.

     The S&P SMALLCAP 600 is composed of 600 small-capitalization stocks traded
on domestic exchanges. It is considered a broad measure of small-company stock
performance.

     The FUND BENCHMARK consists of approximately 165 utilities stocks that meet
the fund's investment criteria. The benchmark's composition by industry is
approximately 55% telephone and communication services, 30% electric and natural
gas companies, and 15% utilities-related companies, such as manufacturers of
communications equipment.

     The S&P ELECTRIC INDEX is composed of 26 electric power companies in the
S&P 500.

     The S&P NATURAL GAS INDEX is composed of 11 natural gas distributors and
pipeline companies in the S&P 500.

     The S&P TELECOMMUNICATIONS (LONG DISTANCE) INDEX is composed of four
long-distance telephone companies in the S&P 500.

     The S&P TELEPHONE INDEX is composed of nine regional telephone companies in
the S&P 500.

LIPPER RANKINGS

     LIPPER INC. is an independent mutual fund ranking service that groups funds
according to their investment objective. Rankings are based on average annual
returns for each fund in a given category for the periods indicated. Rankings
are not included for periods less than one year.

     Lipper's UTILITY FUNDS category consists of funds that invest at least 65%
of their portfolios in utilities stocks.

* Investing in these funds involves special risks resulting from their
  concentrated investment objectives. They are not intended to serve as a
  complete investment program by themselves.

RETURNS

* TOTAL RETURN figures show the overall percentage change in the value of a
hypothetical investment in the fund and assume that all of the fund's
distributions are reinvested.

* AVERAGE ANNUAL RETURNS illustrate the annually compounded returns that would
have produced the fund's cumulative total returns if the fund's performance had
been constant over the entire period. Average annual returns smooth out
variations in a fund's return; they are not the same as fiscal year-by-year
results. For fiscal year-by-year total returns, please refer to the "Financial
Highlights" on pages 17-18.

PORTFOLIO STATISTICS

* NUMBER OF COMPANIES -- the number of different companies held by the fund on a
given date.

* 30-DAY SEC YIELD -- net investment income earned by the fund over a 30-day
period, expressed as an annual percentage rate based on the fund's share price
at the end of the 30-day period. The SEC yield should be regarded as an estimate
of the fund's dividend income, and it may not equal the fund's actual income
distribution rate, the income paid to a shareholder's account, or the income
reported in the fund's financial statements.

* PRICE/EARNINGS (P/E) RATIO -- a stock value measurement calculated by dividing
a company's stock price by its earnings per share, with the result expressed as
a multiple instead of as a percentage. (Earnings per share is calculated by
dividing the after-tax earnings of a corporation by its outstanding shares.)

* PORTFOLIO TURNOVER-- the percentage of the fund's investment portfolio that is
replaced during a given time period, usually a year. Actively managed portfolios
tend to have higher turnover than passively managed portfolios such as index
funds.

* EXPENSE RATIO -- the operating expenses of the fund, expressed as a percentage
of average net assets. Shareholders pay an annual fee to the investment manager
for investment advisory and management services. The expenses and fees are
deducted from fund income, not from each shareholder account. (See Note 2 in the
Notes to Financial Statements.)

TYPES OF STOCKS

* BLUE CHIP STOCKS -- stocks of the most established companies in American
industry. They are generally large, fairly stable companies that have
demonstrated consistent earnings and usually have long-term growth potential.
Examples include General Electric and Coca-Cola.

* CYCLICAL STOCKS -- stocks whose price and earnings fluctuations tend to follow
the ups and downs of the business cycle. Examples include the stocks of
automobile manufacturers, steel producers, and textile operators.

* GROWTH STOCKS -- stocks of companies that have experienced above-average
earnings growth and appear likely to continue such growth. These stocks often
sell at high P/E ratios. Examples can include the stocks of high-tech,
healthcare, and consumer staple companies.

* LARGE-CAPITALIZATION ("LARGE-CAP") STOCKS -- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) of more
than $8.7 billion. This is Lipper's market-capitalization breakpoint as of June
30, 2000, although it may be subject to change based on market fluctuations. The
Dow Jones Industrial Average and the S&P 500 are representative indexes of
large-cap stock performance.

* MEDIUM-CAPITALIZATION ("MID-CAP") STOCKS -- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) between
$2.3 billion and $8.7 billion. This is Lipper's market-capitalization breakpoint
as of June 30, 2000, although it may be subject to change based on market
fluctuations. The S&P 400 and Russell 2500 are representative of mid-cap stock
performance.

* SMALL-CAPITALIZATION ("SMALL-CAP") STOCKS -- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) of less
than $2.3 billion. This is Lipper's market-capitalization breakpoint as of June
30, 2000, although it may be subject to change based on market fluctuations. The
S&P 600 and the Russell 2000 are representative of small-cap stock performance.

* VALUE STOCKS -- stocks that are purchased because they are relatively
inexpensive. These stocks are typically characterized by low P/E ratios.

FUND CLASSIFICATIONS

    Please be aware that the fund's category may change over time. Therefore, it
is important that you read a fund's prospectus or fund profile carefully before
investing to ensure its objectives, policies, and risk potential are consistent
with your needs.

INVESTMENT OBJECTIVE

    The investment objective may be based on the fund's objective as stated in
its prospectus or fund profile, or the fund's categorization by independent
rating organizations based on its management style.

* CAPITAL PRESERVATION -- offers taxable and tax-free money market funds for
relative stability of principal and liquidity.

* INCOME -- offers funds that can provide current income and competitive yields,
as well as a strong and stable foundation and generally lower volatility levels
than stock funds.

* GROWTH & INCOME -- offers funds that emphasize both growth and income provided
by either dividend-paying equities or a combination of equity and fixed-income
securities.

* GROWTH -- offers funds with a focus on capital appreciation and long-term
growth, generally providing high return potential with corresponding high
price-fluctuation risk.

RISK

    The classification of funds by risk category is based on quantitative
historical measures as well as qualitative prospective measures. It is not
intended to be a precise indicator of future risk or return levels. The degree
of risk within each category can vary significantly, and some fund returns have
historically been higher than more aggressive funds or lower than more
conservative funds.

* CONSERVATIVE -- these funds generally provide lower return potential with
either low or minimal price-fluctuation risk.

* MODERATE -- these funds generally provide moderate return potential with
moderate price-fluctuation risk.

* AGGRESSIVE -- these funds generally provide high return potential with
corresponding high price-fluctuation risk.

The investment objective may be based on the fund's objective as stated in its

organizations based on its management style.

The classification of funds by risk category is based on quantitative historical
measures as well as qualitative prospective measures. It is not intended to be a
precise indicator of future risk or return levels. The degree of risk within
each category can vary significantly, and some fund returns have historically
been higher than more aggressive funds or lower than more conservative funds.
Please be aware that a fund's category may change over time. Therefore, it is
important that you read a fund's prospectus or fund profile carefully before
investing to ensure its objectives, policies and risk potential are consistent
with your needs. For a definition of fund categories, see the Glossary.

* While listed within the Income investment objective, the Target funds do not
pay current dividend income. Income dividends are distributed once a year in
December. The Target funds are listed in all three risk categories due to the
dramatic price volatility investors may experience during certain market
conditions. If held to their target dates, however, they can offer a
conservative, dependable way to invest for a specific time horizon.

fund. These documents contain important information including charges and
expenses, and you should read them carefully before you invest or send money.
