HAVE THE PRINCIPLES OF INVESTING CHANGED?

In a world of frenetic change in business, technology, and the financial
markets, it is natural to wonder whether the basic principles of investing have
changed.

        We don't think so.

        The most successful investors over the coming decade will be those who
began the new century with a fundamental understanding of risk and who had the
discipline to stick with long-term investment programs.

    Certainly, investors today confront a challenging, even unprecedented,
environment. Valuations of market indexes are at or near historic highs. The
strength and duration of the bull market in U.S. stocks have inflated people's
expectations and diminished their recognition of the market's considerable
risks. And the incredible divergence in stock returns--many technology-related
stocks gained 100% or more in 1999, yet prices fell for more than half of all
stocks--has made some investors question the idea of diversification.

    And then there is the Internet. Undeniably, it is a powerful medium for
communications and transacting business. For investors, the Internet is a vast
source of information about investments, and online trading has made it
inexpensive and convenient to trade stocks and invest in mutual funds.

    However, new tools do not guarantee good workmanship. Information is not the
same as wisdom. Indeed, much of the information, opinion, and rumor that swirl
about financial markets each day amounts to "noise" of no lasting significance.
And the fact that rapid-fire trading is easy does not make it beneficial.
Frequent trading is almost always counterproductive because costs--even at low
commission rates--and taxes detract from the returns that the markets provide.
Sadly, many investors jump into a "hot" mutual fund just in time to see it cool
off. Meanwhile, long-term fund investors are hurt by speculative trading
activity because they bear part of the costs involved in accommodating purchases
and redemptions.

    Vanguard believes that intelligent investors should resist short-term
thinking and focus instead on a few time-tested principles:

    - Invest for the long term. Pursuing your long-term investment goals is more
like a marathon than a sprint.

    - Diversify your investments with holdings in stocks, bonds, and cash
investments. Remember that, at any moment, some part of a diversified portfolio
will lag other parts, and be wary of taking on more risk by "piling onto" the
best-performing part of your holdings. Today's leader could well be tomorrow's
laggard.

    - Step back from the daily frenzy of the markets; focus on your overall
asset allocation.

    - Capture as much of the market's return as possible by minimizing costs and
taxes. Costs and taxes diminish long-term returns while doing nothing to reduce
the risks you incur as an investor.

REPORT FROM THE CHAIRMAN

[PHOTO]
John J. Brennan

    The overall U.S. stock market posted a modest gain during the six months
ended July 31, 2000, the first half of the fiscal year for the Vanguard
Specialized Funds.  Results from different segments of the equity markets varied
widely, as they often do, and these variations were reflected in the returns of
our five funds.

    It was a terrific half-year for our Health Care, Energy, and REIT Index
Funds and a subpar one for our Utilities Income and Gold and Precious Metals
Funds. Returns stretched across a wide band, ranging from a 27.6% gain for the
Health Care Fund to a decline of -12.4% for the Gold and Precious Metals Fund.
The table at right presents the six-month total returns (capital change plus
reinvested dividends) of each fund, along with those of its comparative fund
group and its benchmark index.

    Details on each fund, including per-share net asset values, income
dividends, and any capital gains distributions, are presented in the table that
follows this letter.

THE PERIOD IN REVIEW

The U.S. economy continued to exhibit  impressive  stamina during the six months
ended July 31. The economy expanded at a terrific pace and unemployment remained
low. Inflation stayed tame, though it showed signs of reigniting.

    For the U.S. stock market, it was a topsy-turvy half-year. Investors,
worrying that the economy was growing too rapidly, seemed to be increasingly
concerned about the lofty valuations of many growth-oriented stocks,
particularly technology and Internet companies. Many high-flying tech stocks
nosedived, and market leadership flip-flopped between growth and value stocks
and small-capitalization and large-cap stocks.

    The Wilshire 5000 Total Market Index, a measure of the entire U.S. market,
returned 1.5% for the half-year, while the large-cap-dominated Standard & Poor's
500 Index returned 3.2%. The S&P 500's growth stocks--those with prices that are
above average in relation to such measures as earnings and book value--returned
5.0% during the six months, versus 1.1% for the index's value component. Among
small stocks, the growth/value split was reversed--and much wider. The value
stocks within the

                                       1
<PAGE>   4

Russell 2000 Index gained 12.3%, while its growth stocks declined -6.6%. The
tech-heavy Nasdaq Composite Index, which is packed with growth stocks, at one
point lost more than a third of its value before recovering somewhat to end with
a -3.9% return for the period.

    Within the S&P 500, the "other energy" sector--a group that includes mining
and drilling companies--led the way with a return of 22.0%, helped along by a
sharp rise in oil and natural gas prices. The utilities group was the laggard,
dropping -15.1%, in part because of a steep decline among telephone companies,
particularly long-distance carriers. Banks and financial services firms bounced
back from a difficult 1999, as did real estate investments, which saw a
particularly strong six months.

    Health care stocks within the S&P 500 returned a solid 9.4% for the six
months. Biotechnology stocks registered huge gains early in the period, then
plummeted from mid-March through May. Investors recoiled from the group because
of comments from President Bill Clinton and British Prime Minister Tony Blair
that were interpreted as meaning that their governments would cut into company
profits from genetic research. But biotech stocks recovered some of their losses
in June and July.

    In the bond market, yields of short-term securities rose while those on
longer-term bonds declined. The Federal Reserve Board continued its
anti-inflation campaign, hiking its target for short-term interest rates three
times during the half-year by a total of 100 basis points (1 percentage point).
The decline in longer-term rates was due to the U.S. Treasury's cutbacks in
issuance of new securities and its decision to buy back some of its long-term
debt. The yield of the 30-year U.S. Treasury bond, which moves in the opposite
direction from its price, declined 71 basis points to 5.78% as of July 31. The
yield of the 10-year U.S. Treasury note slipped 64 basis points to 6.03%.
Overall, bonds outperformed stocks during the period. The Lehman Brothers
Aggregate Bond Index, a proxy for the entire U.S. taxable bond market,
registered a solid six-month total return of 5.3%.

HEALTH CARE FUND

During the six months ended July 31, health care stocks continued a rally that
began in late 1999. The Health Care Fund gained 27.6% for the period--a return
that would have been considered remarkable for a full year, let alone six
months. The fund's return surpassed that of its average peer by 4.4 percentage
points and was almost triple the S&P Health Sector Index's 9.4% return.

    Our performance was aided considerably by a surge in prices for several
stocks, including Pharmacia, which constituted 7.7% of the fund's assets as of
July 31--by far the largest holding. The fund also expanded its position in
health services by buying such stocks as Quest Diagnostics and Cardinal Health,
which registered strong gains.

    Early in the period, our investment adviser, Wellington Management Company,
trimmed the portfolio's position among biotechnology stocks. In particular,
Immunex, formerly the fund's largest holding, fell to the number-three position.
The move proved timely because it allowed our fund to avoid the worst of the
spring slump in biotech stocks. While Immunex itself ended up with a gain for
the period, some biotech stocks never recovered their early-March highs.

    The Health Care Fund's strategy of diversifying its assets across various
segments of the health care industry and across national borders has helped
limit the fund's volatility. Roughly one-quarter of the fund's assets are
invested in companies based outside the United States.

                                       2

ENERGY FUND

Vanguard Energy Fund booked a terrific six months, both on an absolute basis and
relative to competing mutual funds. The fund earned 17.8% for the half-year,
doubling the return of the S&P Energy Sector Index and topping that of the
average energy mutual fund by more than 5 percentage points.

    Increases in the price of oil and particularly natural gas, which rose more
than 60% during the six months, created an excellent environment for
energy-related companies. Oil prices began the period at about $25 a barrel but
rose to nearly $35 in the spring before receding a bit after the Organization of
Petroleum Exporting Countries decided to increase production modestly. Natural
gas prices were driven higher because supplies were low, owing primarily to a
cutback in gas production two years ago.

    Of course, as oil and gas prices rose, drilling also increased rapidly.
Three of the fund's largest holdings--Baker Hughes, Noble Drilling, and
Weatherford International--advanced more than 40% during the period.

    Over the past several years, the energy industry has become more global in
nature. In fact, U.S. oil companies, which in 1985 accounted for 70% of the
total market capitalization of the world's oil industry, now make up about 45%
of it. Over the past two years, for example, British Petroleum has purchased
Amoco and Arco. As a result of this shift, Vanguard Energy Fund's board of
trustees has approved an increase in the limit on international investments,
from 30% to 50% of fund assets. This increase provides our investment adviser,
Wellington Management Company, with more investment flexibility. We believe that
the change will have only a modest effect on the fund's overall risk level and
that any increase in risk will be more than offset by the benefits of increasing
the fund's exposure to international companies. As of July 31, more than
one-quarter of the fund's assets were invested in companies based outside the
United States.

REIT INDEX FUND

After two years of disappointing performance, real estate investment trusts
provided some of the most attractive returns among equities during the past six
months. The REIT Index Fund gained 22.5%, a result that was slightly higher than
that of its target index and almost a full percentage point better than that of
its average peer.

    Unexpectedly strong second-quarter earnings reports from many REITs fueled
the gains, as did the continuing health of the real estate market. Demand for
commercial and residential property grew at a faster pace than the supply of
rental properties. The nation's office vacancy rate dropped to a record low of
around 9%. Higher mortgage rates prompted an uptick in renting over buying,
which heightened demand for apartments.

    The relatively low prices and high yields of REITs also seemed to lure
investors during a period of high volatility in the stock market. Studies
indicate that there is very little correlation between real estate equities and
broader stock indexes in general. In other words, REITs often rise in value
while other stocks go down, and vice versa. Lately, that inverse relationship
seems especially true of REITs and growth tech stocks, such as those in the
Nasdaq Composite Index. Whether this relationship continues remains to be seen,
but REITs remain a good way to diversify a stock portfolio and to provide
healthy current income.

UTILITIES INCOME FUND

Vanguard Utilities Income Fund returned -1.4% for the half-year, falling just
short of the -1.2% return of its average peer. However, your fund's return was
far behind the 6.2% gain of its unmanaged benchmark index.

                                       3
<PAGE>   6

    The declines among utility stocks during the six months were mostly confined
to the telephone industry, which was hurt by intense competition between
long-distance and wireless carriers and higher regulatory hurdles for mergers.
Specifically, your fund was hurt by a decline in Sprint Corp., which fell
sharply after the government's decision to oppose Sprint's merger with WorldCom.
Montana Power, the fund's fifth-largest holding, which includes traditional
utility businesses as well as a telecommunications arm that has built
fiber-optics networks along property it owns, also had a difficult six months,
declining about -30%.

    The tough environment for telephone stocks did not spill over into other
types of utilities. The fund's electric utilities performed well, and its
energy-related holdings--particularly those that benefited from the increasing
demand for natural gas--fared even better.

    As we mentioned in our annual report to you six months ago, we modified the
fund's investment guidelines on April 1, 2000, to allow the investment adviser,
Wellington Management Company, to invest up to 25% of the fund's assets in
foreign-based utility companies. In addition, we eliminated the requirement that
the fund must invest at least 10% of its assets in utility bonds. As of July 31,
the fund held 16% of its assets in non-U.S. companies, and it owned no bonds.

GOLD AND PRECIOUS METALS FUND

Vanguard Gold and Precious Metals Fund returned -12.4% for the six months, a
disappointing result that fell slightly short of the -11.7% return of the fund's
average peer and the -10.9% return of its unmanaged benchmark index, the Salomon
Smith Barney World Equity Gold Index.

    The fund performed poorly during the first four months of the fiscal
half-year, declining nearly -18% from February through May as platinum and
mining companies struggled. However, over the final two months of the period the
fund came on strong, gaining 6.3% in June and July and easily outpacing the
-3.1% decline for the Salomon Smith Barney World Gold Index for the same period.

    During the half-year, gold bullion prices were little changed on balance,
despite a brief rally early in the summer. Therefore, much of the industry's
attention focused on a pickup in merger activity, which involved several of the
biggest producers.

    In the platinum market, prices rose about 30% during the six months and
approached a record high earlier this summer. Decreased platinum production in
Russia and heavier demand from car manufacturers, who use the metal in some
emission-control devices, drove the increase. The Gold and Precious Metals Fund
holds a big stake in platinum companies, and the price surge boosted the fund's
performance late in the period. The fund's two largest holdings, which total
about 20% of assets, are platinum producers, as are several others in its
top-ten group.

    The report from the fund's investment adviser, M&G Investment Management, on
page 12, includes more information about specific securities in which the fund
invested during the half-year.

    It is important to note that the risk of investing in a particular market
sector or industry is increased by the fund's concentration within the gold and
precious metals segment. As of July 31, the fund's ten largest holdings
accounted for more than 60% of its total assets. Thus, investors in the fund
must be prepared for considerable volatility.

    All of the Vanguard Specialized Funds are aided in their quest to provide
superior long-term returns by costs that are much lower than those of their
average peers. The


                                       4
<PAGE>   7

expense ratio (annualized expenses as a percentage of net assets) of each of our
funds is just a fraction of the average for similar funds. In fact, the
difference between the expenses charged by two of our funds--the Energy Fund and
the Health Care Fund--and their average peers is about 1.35 percentage points,
or $13.50 per $1,000 invested. Such a big gap is difficult for competitors to
consistently overcome. While our expense ratios range from 0.34% to 0.66%, those
of our competitors range from 1.45% to 1.95%.

IN SUMMARY

The volatility of the past six months underscores the fact that unpredictability
is par for the course in financial markets. Funds that invest in particular
market sectors, as the Vanguard Specialized Funds do, can be especially
volatile. But for investors who understand the added risks that a concentrated
investment may entail--including wide swings in the prices of commodities such
as gold, gas, or oil--such funds can add to the diversification of a balanced
investment program.

    As always, we recommend that you maintain a balanced and diversified
portfolio of low-cost stock, bond, and money market funds in a proportion that
is consistent with your goals, time horizon, risk tolerance, and financial
resources.

IN MEMORY

It is with great sadness that I report the death of John C. Sawhill, an
independent trustee of the funds and a member of The Vanguard Group's board of
directors since 1991. John, an economist who was president and chief executive
officer of The Nature Conservancy, died on May 18 at age 63. He was a senior
lecturer at the Harvard Business School and had formerly served as president of
New York University and as deputy secretary of the U.S. Department of Energy
under President Jimmy Carter. John was a remarkable man who was full of energy,
vigor, and life. His experience and wisdom added a great deal to Vanguard, and
his death is a blow to everyone who knew and loved him. Though John's work on
behalf of our funds was often carried on behind the scenes, he was a dedicated
advocate for the best interests of our shareholders. He will be missed.

NOTICE TO SHAREHOLDERS

In the past, the quarterly income dividend that Vanguard Utilities Income Fund
distributed to shareholders during the first nine months of the year was paid
at a set rate of $0.13 per share. The remainder of the income for the calender
year was distributed in December. Beginning with the quarterly dividend of
$0.10 per share that was paid in March 2000, the fund is distributing income on
a "pay as you go" basis, rather than according to a set rate. This policy
change provides for a more even distribution of income throughout the year.

THE MARKETS IN PERSPECTIVE
SIX MONTHS ENDED JULY 31, 2000


After playing second fiddle to stocks in the past several years, bonds provided
both a smoother and a more profitable ride than stocks during the six months
ended July 31, 2000.  The Lehman Aggregate Bond Index--a proxy for the
investment-grade taxable bond market--recorded a 5.3% return, well ahead of the
1.5% return for the entire U.S. stock market, as measured by the Wilshire 5000
Index. Stock investors encountered considerable turbulence, as big day-to-day
fluctuations in stocks were commonplace.  And outside of the United  States,
stocks on average declined during the six months.

    The economic backdrop was murky. Growth was quite robust--better than 5%
after inflation--in the United States. Overseas economies also were picking up
strength, and corporations generally registered solid profit gains. Still,
investors were uncertain whether the economic good times would keep rolling,
given that the Federal Reserve Board and other central banks were raising
interest rates during the period.

    The Fed, with three rate increases totaling 1 percentage point, sought to
cool off the economy to keep it from overheating and pushing up inflation.
Because of sharply higher costs for oil and other energy products, the Consumer
Price Index gained 2.3% during the six months and 3.5% for the 12 months ended
July 31. Yet core inflation, which excludes energy and food items, registered a
moderate 2.4% gain during the 12 months ended July 31.

U.S. STOCK MARKETS

Rising profits, the powerful economy, and continued optimism--especially for the
"new economy" TMT stocks (technology, media, and telecommunications)--kept
market averages rising in February and early March. But in mid-March, value
stocks took charge and TMT stocks slumped. Market leadership flip-flopped again
in June, when growth stocks held sway, and in July, when value stocks
outperformed growth stocks.

    The period was marked not only by volatility in market averages but also by
extreme moves in individual stocks. Wall Street was unforgiving: Companies that
disappointed market expectations saw their stock prices plunge. The
large-capitalization S&P 500 Index posted a 3.2% return, more than double that
of the overall market, and the small-cap Russell 2000 Index edged up 1.3%. The
Nasdaq Composite Index, which had stratospheric gains in 1999, lost some
altitude, registering a -3.9% return.

                                       7
<PAGE>   10

    The rise in oil and natural gas prices helped oil-exploration and services
companies in the "other energy" group to post the market's biggest gains: an
average of 22%. Financial services companies, whose stocks had been hurt by
rising interest rates in 1999, rebounded with a 13% return. Another 1999
laggard, the health care sector, posted gains exceeding 9% during the past
half-year. Big drops in regional Bell companies and AT&T caused a -15% return
for the utilities sector, the worst for any market group. The materials &
processing group fell -9%, largely because higher energy costs hurt
energy-intensive companies such as chemical and aluminum makers.

U.S. BOND MARKETS

The Fed's three increases in its target federal funds rate (charged on overnight
loans between banks) elevated the rate by 1 percentage point to 6.50% during the
six months. However, because the market had anticipated some tightening by the
Fed, yields of 3-month U.S. Treasury bills rose only half as far (0.53
percentage point, or 53 basis points, to 6.22%). And on longer-term Treasury
securities, yields actually fell and prices rose. In part, this was due to a
shrinking supply of Treasury debt: A large and growing federal budget surplus
allows the Treasury to issue fewer new bonds and to buy back billions of
dollars' worth of outstanding bonds. The 10-year Treasury note's yield declined
64 basis points to 6.03% on July 31, and the yield of the 30-year Treasury fell
71 basis points to 5.78%.

    Because short-term rates moved higher while long-term rates slid, there was
an "inversion" in the U.S. Treasury yield curve. Instead of the usual upward
slope--with yields increasing along with maturity--the curve sloped downward. On
July 31, the 5.78% yield of 30-year Treasuries was 55 basis points lower than
the 6.33% yield of 3-year Treasury notes. Falling rates mean rising prices for
bonds, of course, and the 5.3% return of the Lehman Aggregate Bond Index during
the six months reflected a price gain of 1.7% in addition to an income return of
3.6%.

    Corporate bonds didn't fare as well as Treasuries, in part because of a very
different supply situation--corporations were issuing large amounts of new debt.
Also, heavy borrowing by companies and the Fed's efforts to slow the economy
raised the chances that some companies would have trouble paying their debts.
Concern about credit quality was evident in the split between returns for low-
and high-quality corporate bonds: a zero return for the Lehman High Yield Index
of low-quality "junk" bonds, versus 4.8% for the high-quality Lehman Credit A or
Better Index. Mortgage-backed bonds and municipal bonds, which also boast high
credit quality, had solid returns: 5.6% for the Lehman GNMA Index and 4.8% for
the tax-exempt Lehman 7 Year Municipal Bond Index.

INTERNATIONAL STOCK MARKETS

Because of a rise in the value of the U.S. dollar against most other currencies
and a slump in Asian markets, international stocks were generally unprofitable
for U.S. investors during the past six months. Although the Morgan Stanley
Capital International Europe, Australasia, Far East (MSCI EAFE) Index of
developed foreign markets registered a 3.1% return in local currencies, the
stronger dollar resulted in a -1.7% return for U.S. investors.

    The MSCI Europe Index generated an 8.4% return in euros, the common currency
of 11 European countries. However, this was cut to a 2.8% return for
dollar-based investors. The MSCI Pacific Free Index declined -10.6% in dollars
and -8.1% in local currencies due to a slump in Japanese stocks, which account
for more than 75% of the index.

    The Select Emerging Markets Free Index fell -10.0% in U.S. dollars, stung by
weakness in South Korea (-18%), South Africa (-17%), Thailand (-50%), and Turkey
(-16%). Israel was the biggest gainer among emerging markets, with a 28% return.

REPORT FROM WELLINGTON MANAGEMENT COMPANY, LLP
HEALTH CARE FUND

Vanguard Health Care Fund gained 27.6% in the fiscal half-year ended July 31.
This result well exceeded the 9.4% gain of the S&P Health Sector Index.  It also
bettered the 23.2% return of the average health/biotechnology mutual fund. The
half-year was a tumultuous one in health care. A biotechnology investment bubble
burst in March, but biotech stocks substantially recovered in June and July. By
selling about half of our biotech stake into the bubble, we were able to
mitigate, to some degree, the volatility that rocked this sector.  Biotech
holdings that significantly helped the fund's performance were Immunex, Vertex
Pharmaceuticals, Gilead Sciences, and Human Genome Sciences.

    We significantly increased our holdings among health-services companies. We
believe that this area, which has been the weakest part of the health care
sector for the past seven years, now offers good upside potential with less risk
than exists elsewhere. This strategy has already begun to bear fruit, as
evidenced by the excellent returns from Quest Diagnostics, UnitedHealth Group,
and Cardinal Health.

    Among major pharmaceutical companies, which as a group turned in a mixed
performance during the six months, Pharmacia, the fund's largest holding, was a
standout gainer.

    We believe that the biggest factor in the strong relative performance of
health care stocks has been the heavy cash flow into health-sector mutual
funds--a development prompted by the genomics revolution. It is important to
note that the fundamental outlook for health care has not improved in any
significant way, yet stock prices in the sector have moved quite a bit higher.
It is also fair to say that we are entering a period during which political
uncertainty is increasing. In addition, a higher rate of patent expirations for
important drugs will slow overall profit growth. Consequently, we expect that a
headwind could dampen the sector's returns in the next few years. However, we
believe that Vanguard Health Care Fund, with its conservative diversified
stance, is well positioned for this environment. We also believe that, in the
long term, health care is one of the most attractive areas of the economy.

INVESTMENT PHILOSOPHY

Each fund reflects a belief that investors who seek to emphasize a given
economic sector as part of a long-term, balanced investment program are best
served by holding a portfolio of securities well-diversified across that sector.

REPORT FROM WELLINGTON MANAGEMENT COMPANY, LLP
ENERGY FUND

Vanguard Energy Fund returned 17.8% during the first six months of its 2001
fiscal year, compared with gains of 3.2% for the S&P 500 Index and 12.3% for the
average natural-resources fund.  The fund's return was also well ahead of the
8.9% return of the S&P Energy Sector Index.

    Energy markets continued to be quite strong during the period. The price of
oil remained within a range of $25 to $30 a barrel during most of the period.
However, high oil prices are beginning to have some impact on supply and demand.
Oil production is expected to rise in 2000, while growth in demand is expected
to decline  worldwide.  Because the  supply-demand  situation is  improving  and
because  members of OPEC do not want to see higher  prices,  we expect  that oil
prices will stabilize roughly around $25.

    The price of natural gas in North America was also quite strong, increasing
from about $2.50 per thousand cubic feet at the end of January to about $4.00 on
July 31. Simply put, natural gas prices are high because drilling activity in
1998 was very low. The slump in oil prices during 1998 curtailed the
availability of funds for both oil and gas exploration. Three consecutive mild
winters across much of the United States have helped to keep gas prices from
rising even higher, but drilling for gas in North America has rebounded sharply
since early 1999. We expect the natural gas market to remain healthy for two
reasons: strong demand resulting from the start-up of new gas-fired electricity
generating plants and the possibility of more normal (i.e., colder) winter
weather.

    Early in 2000, oil services companies provided the best returns in the
energy sector, but the market broadened in March and oil and gas producers also
appreciated in value. As more investors understand that the 1998 oil price
collapse is not likely to be repeated soon, energy stocks should provide
attractive returns. Furthermore, energy companies generally continue to be
cautious about expenditures and seem to be more focused on financial returns.
This is an important change from the energy boom of 1996-1997, when many
companies emphasized production growth at the expense of profits. We own
companies that have records of above-average financial returns, such as Exxon
Mobil, TotalFinaElf, and Alberta Energy, and companies whose financial returns
we expect to improve, such as Baker Hughes and Unocal.

    Vanguard Energy Fund continues to seek exposure across the various segments
of the energy sector, with emphasis on companies that we expect will provide
above-average long-term appreciation.

REPORT FROM WELLINGTON MANAGEMENT COMPANY, LLP
UTILITIES INCOME FUND


Vanguard Utilities Income Fund declined -1.4% for the six months ended July 31,
in line with the -1.2% return for the average utility mutual fund but behind the
fund's composite benchmark, which gained 6.2% during the period.

    The top-performing sector within our investment universe was natural gas,
which advanced 16.0% during the period. Natural gas stocks benefited from
accelerating demand (mainly to fuel new electric generating capacity) and from
strong growth in energy trading and marketing of deregulated services. The
electric utility sector, which returned 6.6% during the period, benefited from
surging demand from the increasingly computerized economy. The sector's solid
gains can be attributed to relatively attractive valuations, particularly versus
more growth-oriented segments of the market.

    The telephone sector held back the overall performance of utilities.
Telephone utilities declined -16.7% during the six months, reflecting negative
news on revenues and earnings from several large long distance carriers. Two
other factors also prompted severe selling pressure on telephone stocks:
accelerating competitive pricing in consumer long distance and the federal
government's surprising decision to block the Sprint/WorldCom merger. The
Utilities Income Fund was hurt by its holdings in Sprint and Montana Power, an
electric and natural gas utility that also has a telecommunications arm.
Declining revenue forecasts have raised the question of whether too much capital
is chasing the media/Internet demand for broadband capacity. One sign of this
phenomenon could be the rapid "commoditization" of the consumer long-distance
market. Another example is the bidding war now occurring in Europe for the next
generation of wireless spectrum--another delivery route for broadband
applications.

    As we wrote to you six months ago, the fund's investment guidelines have
been modified so that we no longer must keep a portion of assets in bonds. This
change became effective in April, and the fund's bond position was eliminated by
early May. At the same time, the fund acquired more leeway for investments in
foreign-based utility companies, which now may account for up to 25% of assets.
As of July 31, about 16% of the fund's assets were invested in non-U.S. stocks,
up from about 12% six months ago.

    The hot growth sector within utilities is the deregulated merchant
generation market--those companies that provide power and other services to
regional and local utilities. The group is represented in Vanguard Utilities
Income Fund by Calpine, Duke Energy, and Enron. This segment of the market has
benefited from higher-than-expected electricity prices stemming from both a
shortage of new generating capacity and the rapid rise in natural gas prices. We
believe this situation will persist for several years, mainly because of poor
regulatory initiatives, local transmission constraints, and shortages in natural
gas reserves, all of which will result in higher prices for both the capacity
and energy components in electricity bills.

REPORT FROM M&G INVESTMENT MANAGEMENT LTD.
GOLD AND PRECIOUS METALS FUND


Vanguard Gold and Precious Metals Fund returned -12.4% during the six months
ended July 31, 2000, falling short of the returns of both its average mutual
fund peer and its unmanaged benchmark index during what was an extremely
difficult period for precious metals investments.

    Although disappointing, our results disguise the significant contrast
between the fund's performance during the first three months of the period and
its results for the final three months. During the first half of the period, a
sell-off in global equity markets and sustained profit-taking in diversified
mining and platinum shares--sectors that had rallied in the previous four
months--combined to produce an extremely weak quarter for mining companies.
Therefore, your fund, which has significant exposure to both platinum and
diversified mining companies, underperformed its comparative measures from
February through April. However, a subsequent sharp rally in these oversold
sectors enabled the fund to close out the half-year on a relatively positive
note.

    During the six months, a number of the fund's core holdings in the
gold-mining sector performed well. Producers Goldfields, Sons of Gwalia, Barrick
Gold, and Newcrest Mining led the way. The rebound in diversified mining
companies from May through July resulted in solid performances for Ashton Mining
and Aber Resources. In addition, a strong rally in the price of platinum allowed
producers Lonmin and Anglo American Platinum to deliver good returns during the
final three months--and for the period as a whole.

    Although the price of gold bullion rose sharply in June in response to a
weakening of the U.S. dollar, the rally proved unsustainable, and the bullion
price ended the half-year almost unchanged from the start of the period.
However, a significant positive theme emerged: the acceleration of the gold
sector's consolidation trend. During the period, Goldfields, the world's
third-largest gold producer, announced a merger with Franco-Nevada Mining. This
was quickly followed by the announcement that Newmont Mining, the world's
number-two gold producer, would merge with Battle Mountain Gold.

    The fund had relatively few transactions during the six months ended July
31. We reduced our exposure to Franco-Nevada Mining and Newmont Mining after the
merger announcements. We invested the proceeds in two new mid-capitalization
companies, Iluka Resources, a diversified mining company based in Australia, and
Meridian Gold, a U.S. gold producer with assets in the United States and Chile.
We also increased our holding in Lonmin, which proved extremely timely given the
strength of platinum shares during the final three months of the period.

    The fund continues to focus on quality mining companies that have a
diversified range of interests. We believe the prospects for these companies
remain extremely favorable. While the current spate of mergers may improve the
performance of gold shares in the short term, these mergers must attack the
problem of supply and overall gold marketing if they are to prove effective at
exacting a longer-lasting change in investor sentiment. We remain extremely
positive about both platinum demand and platinum shares and retain a significant
exposure in this area.

BETA. A measure of the magnitude of a fund's past share-price fluctuations in
relation to the ups and downs of the overall market (or appropriate market
index). The market (or index) is assigned a beta of 1.00, so a fund with a beta
of 1.20 would have seen its share price rise or fall by 12% when the overall
market rose or fell by 10%

CASH INVESTMENTS. The percentage of a fund's net assets invested in "cash
equivalents"--highly liquid, short-term, interest-bearing securities. This
figure does not include cash invested in futures contracts to simulate stock
investment.

COUNTRY DIVERSIFICATION. The percentages of a fund's total net assets invested
in securities of various countries.

EARNINGS GROWTH RATE. The average annual rate of growth in earnings over the
past five years for the stocks now in a fund.

EQUITY INVESTMENT FOCUS. This grid indicates the focus of a fund's equity
holdings in terms of two attributes: market capitalization (large, medium, or
small) and relative valuation (growth, value, or a blend).

EXPENSE RATIO. The percentage of a fund's average net assets used to pay its
annual administrative and advisory expenses. These expenses directly reduce
returns to investors.

FOREIGN HOLDINGS. The percentage of a fund's equity assets represented by stocks
or American Depositary Receipts of companies based outside the United States.

FUND ALLOCATION BY REIT TYPE. An indicator of diversification, this table shows
the percentage of the fund's noncash holdings invested in various real estate
investment trusts, classified according to the types of property they emphasize.

MEDIAN MARKET CAP. An indicator of the size of companies in which a fund
invests; the midpoint of market capitalization (market price x shares
outstanding) of a fund's stocks, weighted by the proportion of the fund's assets
invested in each stock. Stocks representing half of the fund's assets have
market capitalizations above the median, and the rest are below it.

NUMBER OF STOCKS. An indicator of diversification. The more stocks a fund holds,
the more diversified it is and the more likely to perform in line with the
overall stock market.

PRICE/BOOK RATIO. The share price of a stock divided by its net worth, or book
value, per share. For a fund, the weighted average price/book ratio of the
stocks it holds.

PRICE/EARNINGS RATIO. The ratio of a stock's current price to its per-share
earnings over the past year. For a fund, the weighted average P/E of the stocks
it holds. P/E is an indicator of market expectations about corporate prospects;
the higher the P/E, the greater the expectations for a company's future growth.

R-SQUARED. A measure of how much of a fund's past returns can be explained by
the returns from the overall market (or its benchmark index). If a fund's total
return were precisely synchronized with the overall market's return, its
R-squared would be 1.00. If a fund's returns bore no relationship to the
market's returns, its R-squared would be 0.

RETURN ON EQUITY. The annual average rate of return generated by a company
during the past five years for each dollar of shareholder's equity (net income
divided by shareholder's equity). for a fund, the weighted average return on
equity for the companies whose stocks it holds.

SECTOR DIVERSIFICATION. The percentages of a fund's common stocks that come from
each of the major industry groups that compose a broad industry group or the
stock market.

                                       18

<PAGE>   21

TEN LARGEST HOLDINGS. The percentage of net assets that a fund has invested in
its ten largest holdings. (The average for stock mutual funds is about 35%.) As
this percentage rises, a fund's returns are likely to be more volatile because
they are more dependent on the fortunes of a few companies.

TURNOVER RATE. An indication of trading activity during the period. Funds with
high turnover rates incur higher transaction costs and are more likely to

security's market value on the last day of the reporting period. Securities are
grouped and subtotaled by asset type (common stocks, bonds, etc.) and by sector
within the fund's designated industry; international securities, if significant,
may be presented in a separate group. The REIT Index Fund lists its security
holdings in descending market value order. Other assets are added to, and
liabilities are subtracted from, the value of Total Investments to calculate the
fund's Net Assets. Finally, Net Assets are divided by the outstanding shares of
the fund to arrive at its share price, or Net Asset Value (NAV) Per Share.

    At the end of the Statement of Net Assets, you will find a table displaying
the composition of the fund's net assets on both a dollar and per-share basis.
Because all income and any realized gains must be distributed to shareholders
each year, the bulk of net assets consists of Paid in Capital (money invested by
shareholders). The amounts shown for Undistributed Net Investment Income and
Accumulated Net Realized Gains usually approximate the sums the fund had
available to distribute to shareholders as income dividends or capital gains as
of the statement date, but may differ because certain investments or
transactions may be treated differently for financial statement and tax
purposes. Any Accumulated Net Realized Losses, and any cumulative excess of
distributions over net income or net realized gains, will appear as negative
balances. Unrealized Appreciation (Depreciation) is the difference between the
market value of the fund's investments and their cost, and reflects the gains
(losses) that would be realized if the fund were to sell all of its investments
at their statement-date values.

STATEMENT OF OPERATIONS

This Statement shows dividend and interest income earned by each fund during the
reporting period, and details the operating expenses charged to the fund. These
expenses directly reduce the amount of investment income available to pay to
shareholders as dividends. This Statement also shows any Net Gain (Loss)
realized on the sale of investments, and the increase or decrease in the
Unrealized Appreciation (Depreciation) on investments during the period--these
amounts include the effect of foreign currency movements on the value of a
fund's securities. Currency gains (losses) on the translation of other assets
and liabilities are shown separately.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how each fund's total net assets changed during the two
most recent reporting periods. The Operations section summarizes information
detailed in the Statement of Operations. The amounts shown as Distributions to
shareholders from the fund's net income and capital gains may not match the
amounts shown in the Operations section, because distributions are determined on
a tax basis and may be made in a period different from the one in which the
income was earned or the gains were realized on the financial statements. The
Capital Share Transactions section shows the amount shareholders invested in the
fund, either by purchasing shares or by reinvesting distributions, as well as
the amounts redeemed. The corresponding numbers of Shares Issued and Redeemed
are shown at the end of the Statement.

FINANCIAL HIGHLIGHTS

This table summarizes each fund's investment results and distributions to
shareholders on a per-share basis. It also presents the fund's Total Return and
shows net investment income and expenses as percentages of average net assets.
These data will help you assess: the variability of the fund's net income and
total returns from year to year; the relative contributions of net income and
capital gains to the fund's total return; how much it costs to operate the fund;
and the extent to which the fund tends to distribute capital gains. The table
also shows the Portfolio Turnover Rate, a measure of trading activity. A
turnover rate of 100% means that the average security is held in the fund for
one year.

NOTES TO FINANCIAL STATEMENTS

Vanguard Specialized Funds comprise the Health Care, Energy, REIT Index,
Utilities Income, and Gold and Precious Metals Funds, each of which is
registered under the Investment Company Act of 1940 as a diversified open-end
investment company, or mutual fund. The Health Care, Energy, Utilities Income,
and Gold and Precious Metals Funds may invest in securities of foreign issuers,
which may subject them to investment risks not normally associated with
investing in securities of United States corporations.

     A. The following significant accounting policies conform to generally
accepted accounting principles for mutual funds. The funds consistently follow
such policies in preparing their financial statements.

        1. SECURITY VALUATION: Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on the valuation date; such securities not
traded on the valuation date are valued at the mean of the latest quoted bid
and asked prices. Prices are taken from the primary market in which each
security trades. Precious metals are valued at the mean of the latest quoted
bid and asked prices. Temporary cash investments acquired over 60 days to
maturity are valued using the latest bid prices or using valuations based on a
matrix system (which considers such factors as security prices, yields,
maturities, and ratings), both as furnished by independent pricing services.
Other temporary cash investments are valued at amortized cost, which
approximates market value. Securities for which market quotations are not
readily available are valued by methods deemed by the board of trustees to
represent fair value.


       2. FOREIGN CURRENCY: Securities and other assets and liabilities
denominated in foreign currencies are translated into U.S. dollars at
the exchange rates on the valuation date as employed by Morgan Stanley Capital
International in the calculation of its indexes.

       Realized gains (losses) and unrealized appreciation (depreciation) on
investment securities include the effects of changes in exchange rates since
the securities were purchased, combined with the effects of changes in security
prices. 1Fluctuations in the value of other assets and liabilities resulting
from changes in exchange rates are recorded as unrealized foreign currency
gains (losses) until the asset or liability is settled in cash, when they are
recorded as realized foreign currency gains (losses).

       3. FORWARD CURRENCY CONTRACTS: The Health Care Fund enters into forward
currency contracts to protect the value of securities and related receivables
and payables against changes in future foreign exchange rates. The fund's risks
in using these contracts include movement in the values of the foreign
currencies relative to the U.S. dollar and the ability of the counterparties to
fulfill their obligations under the contracts.

       Forward currency contracts are valued at their quoted daily settlement
prices. The aggregate principal amounts of the contracts are not recorded in
the financial statements. Fluctuations in the value of the contracts are
recorded in the Statement of Net Assets as an asset (liability) and in the
Statement of Operations as unrealized appreciation (depreciation) until the
contracts are closed, when they are recorded as realized forward currency
contract gains (losses).

       4. REPURCHASE AGREEMENTS: The funds, along with other members of The
Vanguard Group, transfer uninvested cash balances to a pooled cash account,
which is invested in repurchase agreements secured by U.S. government
securities. Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements mature. Each agreement requires that
the market value of the collateral be sufficient to cover payments of interest
and principal; however, in the event of default or bankruptcy by the other
party to the agreement, retention of the collateral may be subject to legal
proceedings.

       5. DISTRIBUTIONS: Distributions to shareholders are recorded on the
ex-dividend date. Distributions are determined on a tax basis and may differ
from net investment income and realized capital gains for financial reporting
purposes.


                                       42
<PAGE>   45


       6. OTHER: Dividend income is recorded on the ex-dividend date. The REIT
Index Fund's dividend income is recorded at management's estimate of the income
included in distributions received from the REIT investments. Distributions
received in excess of this amount are recorded as a reduction of the cost of
investments. The actual amounts of income and return of capital are determined
by each REIT only after its fiscal year-end, and may differ from the estimated
amounts. Security transactions are accounted for on the date securities are
bought or sold. Costs used to determine realized gains (losses) on the sale of
investment securities are those of the specific securities sold. Premiums and
discounts on debt securities purchased are amortized and accreted,
respectively, to interest income over the lives of the respective securities.
Fees assessed on redemptions of capital shares are credited to paid in capital.

B. Wellington Management Company, LLP, provides investment advisory services to
the Health Care, Energy, and Utilities Income Funds for fees calculated at an
annual percentage rate of average net assets. For the six months ended July 31,
2000, the investment advisory fees of the Health Care, Energy, and Utilities
Income Funds represented an effective annual rate of 0.06% of each fund's
average net assets.

   M&G Investment Management Ltd. provides investment advisory services to
the Gold and Precious Metals Fund for a fee calculated at an annual percentage
rate of average net assets. For the six months ended July 31, 2000, the
investment advisory fee represented an effective annual rate of 0.22% of the
fund's average net assets.

   The Vanguard Group furnishes investment advisory services to the REIT Index
Fund on an at-cost basis.

C. The Vanguard Group furnishes at cost corporate management, administrative,
marketing, and distribution services. The costs of such services are allocated
to each fund under methods approved by the board of trustees. Each fund has
committed to provide up to 0.40% of its net assets in capital contributions to
Vanguard. At July 31, 2000, the funds had contributed capital to Vanguard
(included in Other Assets) of:

   At July 31, 2000, the Health Care and Gold and Precious Metals Funds had net
unrealized foreign currency gains (losses) resulting from the translation of
other assets and liabilities of $(115,000) and $1,000, respectively.

G. Distributions are determined on a tax basis and may differ from net
investment income and realized capital gains for financial reporting purposes.

   During the six months ended July 31, 2000, the funds realized net foreign
currency gains (losses) that increased (decreased) distributable net income for
tax purposes; accordingly such gains (losses) have been reclassified from
accumulated net realized gains (losses) to undistributed net investment income
as follows:

   During the six months ended July 31, 2000, the REIT Index Fund realized
$2,681,000 of net capital gains resulting from in-kind redemptions--in which
shareholders exchange fund shares for securities held by the fund rather than
for cash. Because such gains are not taxable to the fund, and are not
distributed to shareholders, they have been reclassified from accumulated net
realized gains to paid in capital.

   Certain of the Gold and Precious Metals Fund's investments are in securities
considered to be "passive foreign investment companies," for which any
unrealized appreciation and/or realized gains are required to be included in
distributable net income for tax purposes. The cumulative total of
distributions related to passive foreign investment company holdings at July
31, 2000, was $72,000, and is reflected in the balance of undistributed net
investment income.

At January 31, 2000, the funds had available realized losses to offset future
net capital gains through the following fiscal year-ends:

THE PEOPLE WHO GOVERN YOUR FUND

    The trustees of your mutual fund are there to see that the fund is operated
and managed in your best interests since, as a shareholder, you are part owner
of the fund. Your fund trustees also serve on the board of directors of The
Vanguard Group, which is owned by the funds and exists solely to provide
services to them on an at-cost basis.

    Six of Vanguard's seven board members are independent, meaning that they
have no affiliation with Vanguard or the funds they oversee, apart from the
sizable personal investments they have made as private individuals. They bring
distinguished backgrounds in business, academia, and public service to their
task of working with Vanguard officers to establish the policies and oversee the
activities of the funds.

    Among board members' responsibilities are selecting investment advisers for
the funds; monitoring fund operations, performance, and costs; reviewing
contracts; nominating and selecting new trustees/directors; and electing
Vanguard officers.

    The list below provides a brief description of each trustee's professional
affiliations. Noted in parentheses is the year in which the trustee joined the
Vanguard board.
