INVESTMENT OBJECTIVE AND POLICIES
                 Vanguard Quantitative Portfolios, Inc. (the "Fund") is an
                 open-end diversified investment company that seeks to realize
                 a total return (income plus capital change) greater than the
                 return of the aggregate U.S. stock market, as measured by the
                 Standard & Poor's 500 Composite Stock Price Index (the "S&P
                 500 Index"). The Fund will hold a broadly diversified
                 portfolio of common stocks that in aggregate exhibit
                 investment characteristics similar to those of the S&P 500
                 Index. There is no assurance that the Fund will achieve its
                 stated objective.

YIELD AND TOTAL RETURN
                 From time to time the Fund may advertise its yield and total
                 return. Both yield and total return figures are based on
                 historical earnings and are not intended to indicate future
                 performance. The "total return" of the Fund refers to the
                 average annual compounded rates of return over one-, five-
                 and ten-year periods or for the life of the Fund (as stated
                 in the advertisement) that would equate an initial amount
                 invested at the beginning of a stated period to the ending
                 redeemable value of the investment, assuming the reinvestment
                 of all dividend and capital gains distributions.
 
                 The "30-day yield" of the Fund is calculated by dividing the
                 net investment income per share earned during a 30-day period
                 by the net asset value per share on the last day of the
                 period. Net investment income includes interest and dividend
                 income earned on the Fund's securities; it is net of all
                 expenses and all recurring and nonrecurring charges that have
                 been applied to all shareholder accounts. The yield
                 calculation assumes that net investment income earned over 30
                 days is compounded monthly for six months and then
                 annualized. Methods used to calculate advertised yields are
                 standardized for all stock and bond mutual funds. However,
                 these methods differ from the accounting methods used by the
                 Fund to maintain its books and records, and so the advertised
                 30-day yield may not fully reflect the income paid to your
                 own account or the yield reported in the Fund's Annual Report
                 to Shareholders.

INVESTMENT OBJECTIVE
                 The Fund is an open-end diversified investment company. The
                 objective of the Fund is to realize a total investment return
                 (dividend income plus capital change) greater than the return
                 of the aggregate U.S. stock market, as measured by the
                 Standard & Poor's 500 Composite Stock Price Index (the "S&P
                 500 Index"). There is no assurance that the Fund will achieve
                 its stated objective.
- ------------------------------------------------------------------------------
INVESTMENT POLICIES
THE FUND USES QUANTITATIVE TECHNIQUES TO SELECT COMMON STOCKS
                 The Fund will invest in a broadly diversified portfolio of
                 common stocks. At least 65% of the Fund's assets will be
                 invested in securities which are included in the S&P 500
                 Index, while the balance of the Fund's assets may be invested
                 in common stocks not represented in the Index. The Fund is
                 managed without regard to tax ramifications.
 
                 Stocks are selected for the Fund so that, in the aggregate,
                 the investment characteristics of the Fund are similar to
                 those of the S&P 500 Index. These characteristics include
                 such measures as dividend yield (before expenses), price-to-
                 earnings ratio, "beta" (relative volatility), return on
                 equity, and market price-to-book value ratio. However, while
                 maintaining aggregate investment characteristics similar to
                 those of the S&P 500 Index, the Fund seeks to invest in
                 individual common stocks -- including stocks which are not
                 part of the Index -- which will in the aggregate provide a
                 higher total return than the Index. Of course, there can be
                 no assurance that the Fund's investment performance will
                 match or exceed that of the S&P 500 Index.
 
                 To select stocks for the Fund, the Fund's investment adviser
                 first ranks a broad universe of common stocks using several
                 quantitative investment models. These models are based upon
                 such factors as measures of changes in earnings and of
                 relative value based on present and historical price-to-
                 earnings ratios and yields, as well as dividend discount
                 calculations based on corporate cash flow. Once the ranking
                 of common stocks is completed, the adviser, using a technique
                 known as "portfolio optimization," then constructs a
                 portfolio that in the aggregate resembles the S&P 500 Index,
                 but is weighted towards the most attractive stocks in the
                 universe of stocks monitored, as determined by the
                 quantitative models.
 
                 The Fund seeks to remain fully invested in common stocks.
                 However, the Fund is also authorized to invest in certain
                 short-term fixed income securities and in stock index futures
                 contracts and options to a limited extent. See
                 "Implementation of Policies" for a description of these and
                 other investment practices of the Fund.
 
                 The investment objective and policies of the Fund are not
                 fundamental and so may be changed by the Board of Directors
                 without shareholder approval. However, shareholders would be
                 notified prior to a material change in either.

INVESTMENT RISKS
THE FUND IS SUBJECT TO MARKET RISK
                 As a mutual fund investing primarily in common stocks, the
                 Fund is subject to market risk -- i.e., the possibility that
                 common stock prices will decline over short or even extended
                 periods. The U.S. stock market tends to be cyclical, with
                 periods when stock prices generally rise and periods when
                 prices generally decline.
 
                 To illustrate the volatility of stock prices, the following
                 table sets forth the extremes for stock market returns as
                 well as the average return for the period from 1926 to 1993,
                 as measured by the Standard & Poor's 500 Composite Stock
                 Price Index:

</TABLE>
 
                 As shown, from 1926 to 1993, common stocks have provided an
                 annual total return (capital appreciation plus dividend
                 income), on average, of +12.3%. While this average return can
                 be used as a guide for setting reasonable expectations for
                 future stock market returns, it may not be useful for
                 forecasting future returns in any particular period, as stock
                 returns are quite volatile from year to year.
 
                 This table of U.S. stock market returns should not be viewed
                 as a representation of future returns from the Fund or the
                 U.S. stock market. The illustrated returns represent the
                 historical investment performance, which may be a poor guide
                 to future returns. Also, stock market indexes such as the S&P
                 500 are based upon unmanaged portfolios of securities, before
                 transaction costs and other expenses. Such costs will reduce
                 the relative investment performance of the Fund and other
                 "real world" portfolios.
- ------------------------------------------------------------------------------
WHO SHOULD INVEST
INVESTORS SEEKING A "MARGIN OF SUPERIORITY" OVER THE S&P 500 INDEX
                 The Fund is designed for investors whose objective is to
                 achieve a total return marginally superior to the return from
                 the S&P 500 Index with reasonable consistency over time,
                 while minimizing the risk of substantial underperformance
                 during any individual year. Because of the risks associated
                 with common stock investments, the Fund is intended to be a
                 long-term investment vehicle and is not designed to provide
                 investors with a means of speculating on short-term market
                 movements. Investors who engage in excessive account activity
                 generate additional costs which are borne by all of the
                 Fund's shareholders. In order to minimize such costs the Fund
                 has adopted the following policies. The Fund reserves the
                 right to reject any purchase request (including exchange
                 purchases from other Vanguard portfolios) that is reasonably
                 deemed to be disruptive to efficient portfolio management
                 either because of the timing of the investment or previous
                 excessive trading by the investor. Additionally, the Fund has
                 adopted exchange privilege limitations as described in the
                 section "Exchange Privilege Limitations." Finally, the Fund
                 reserves the right to suspend the offering of its shares.
 
<PAGE>
                 No assurance can be given that the Fund will attain its
                 objective or that shareholders will be protected from the
                 risk of loss that is inherent in equity investing. All equity
                 portfolios are influenced by price movements in the broad
                 equity market. Investors may wish to reduce the potential 
                 risk of investing in the Fund by purchasing shares on a 
                 regular, periodic basis (dollar-cost averaging) rather than 
                 making an investment in one lump sum.
 
                 Investors should not consider the Fund a complete investment
                 program, but should also maintain holdings in investments
                 with different risk characteristics, such as bonds and money
                 market instruments. Investors may also wish to complement an
                 investment in the Fund with other types of common stock
                 investments.
- ------------------------------------------------------------------------------
IMPLEMENTATION OF POLICIES
                 The Fund utilizes a variety of investment practices in its
                 effort to surpass the total return of the S&P 500 Index.

THE FUND INVESTS PRIMARILY IN S&P 500 STOCKS
                 The Fund will invest at least 65% of its assets in securities
                 that are included in the S&P 500 Index (the "Index"), and it
                 is expected that the aggregate investment characteristics of
                 the Fund will be similar to those of the Index. The S&P 500
                 Index measures the total investment return (capital change
                 plus income) provided by a universe of 500 common stocks,
                 weighted by their market value. These 500 securities, most of
                 which trade on the New York Stock Exchange, represent over
                 75% of the market value of all U.S. common stocks. Because of
                 the market-value weighting, the 50 largest companies in the
                 Index currently account for approximately 50% of the Index.
 
                 As of December 31, 1993, the five largest companies in the
                 Index were: General Electric (2.7%), Exxon Corporation
                 (2.4%), American Telephone and Telegraph (2.2%), Wal-Mart
                 Stores (1.8%), and Coca Cola (1.7%). The largest industry
                 categories were: international oil companies (7.2%),
                 telephone companies (6.0%), electric power (4.8%), electrical
                 equipment (3.8%), and diversified health care companies
                 (3.6%).
 
                 The S&P 500 Index is an unmanaged, statistical measure of
                 stock market performance. As such, it does not reflect the
                 actual, "real world" costs of investing in common stocks. By
                 contrast, the Fund is actively managed and therefore incurs
                 the normal costs of a mutual fund, including brokerage and
                 execution costs, advisory fees, costs of distribution and
                 administration, and custodial fees.
 
                 Standard & Poor's Corporation chooses the common stocks to be
                 included in the S&P 500 Index solely on a statistical basis.
                 Inclusion of a security in the Index in no way implies an
                 opinion by Standard & Poor's Corporation as to its
                 attractiveness or appropriateness as an investment. Standard
                 & Poor's Corporation is neither a sponsor of nor in any way
                 affiliated with the Fund.

THE FUND MAY INVEST IN SHORT-TERM FIXED INCOME SECURITIES
                 Although it normally seeks to remain substantially fully
                 invested in common stocks, the Fund may invest temporarily in
                 certain short-term fixed income securities. Such securities
                 may be used to invest uncommitted cash balances or to
                 maintain liquidity to meet shareholder redemptions. These
                 securities include: obligations of the United States
                 Government and its agencies or instrumentalities; commercial
<PAGE>
                 paper, bank certificates of deposit, and bankers'
                 acceptances; and repurchase agreements collateralized by
                 these securities.

THE FUND MAY USE FUTURES CONTRACTS AND OPTIONS
                 The Fund may utilize stock futures contracts and options to a
                 limited extent. Specifically, the Fund may enter into futures
                 contracts provided that not more than 5% of its assets are
                 required as a futures contract deposit. In addition, the Fund
                 may enter into futures contracts and options transactions
                 only to the extent that obligations under such contracts or
                 transactions represent not more than 20% of the Fund's
                 assets.
 
                 Futures contracts and options may be used for several
                 reasons: to maintain cash reserves while remaining fully
                 invested, to facilitate trading, to reduce transaction costs,
                 or to seek higher investment returns when a futures contract
                 is priced more attractively than the underlying equity
                 security or index. The Fund may not use futures contracts or
                 options to leverage its net assets.

FUTURES CONTRACTS AND OPTIONS POSE CERTAIN RISKS
                 The primary risks associated with the use of futures
                 contracts and options are: (i) imperfect correlation between
                 the change in market value of the stocks held by the Fund and
                 the prices of futures contracts and options; and (ii)
                 possible lack of a liquid secondary market for a futures
                 contract and the resulting inability to close a futures
                 position prior to its maturity date. The risk of imperfect
                 correlation will be minimized by investing only in those
                 contracts whose behavior is expected to resemble that of the
                 Fund's underlying securities. The risk that the Fund will be
                 unable to close out a futures position will be minimized by
                 entering into such transactions on a national exchange with
                 an active and liquid secondary market.
 
                 The risk of loss in trading futures contracts in some
                 strategies can be substantial, due both to the low margin
                 deposits required and the extremely high degree of leverage
                 involved in futures pricing. As a result, relatively small
                 price movement in a futures contract may result in immediate
                 and substantial loss (or gain) to the investor. When
                 investing in futures contracts, the Fund will segregate cash
                 or cash equivalents in the amount of the underlying
                 obligation.

THE FUND MAY LEND ITS SECURITIES
                 The Fund may lend its investment securities to qualified
                 institutional investors for either short-term or long-term
                 purposes of realizing additional income. Loans of securities
                 by the Fund will be collateralized by cash, letters of
                 credit, or securities issued or guaranteed by the U.S.
                 Government or its agencies. The collateral will equal at
                 least 100% of the current market value of the loaned
                 securities.
 
                 The Fund may borrow money, subject to the limits set forth
                 below, for temporary or emergency purposes, including the
                 meeting of redemption requests which might otherwise require
                 the untimely disposition of securities.

PORTFOLIO TURNOVER IS NOT EXPECTED TO EXCEED 100%
                 Although it generally seeks to invest for the long term, the
                 Fund retains the right to sell securities irrespective of how
                 long they have been held. It is anticipated that the annual
                 portfolio turnover of the Fund will not exceed 100%. A
                 turnover rate of 100% would occur, for example, if all of the
                 securities of the Fund were replaced within one year.

INVESTMENT LIMITATIONS
THE FUND HAS ADOPTED CERTAIN FUNDAMENTAL LIMITATIONS
                 The Fund has adopted certain limitations on its investment
                 practices. Specifically, the Fund will not:
 
                 (a) with respect to 75% of the value of its total assets,
                     purchase the securities of any issuer (except obligations
                     of the United States Government and its
                     instrumentalities) if as a result the Fund would hold
                     more than 10% of the outstanding voting securities of the
                     issuer, or more than 5% of the value of the Fund's total
                     assets would be invested in the securities of such
                     issuer;
                 (b) borrow money, except that the Fund may borrow from banks
                     (or through reverse repurchase agreements), for temporary
                     or emergency (not leveraging) purposes, including the
                     meeting of redemption requests which might otherwise
                     require the untimely disposition of securities, in an
                     amount not exceeding 10% of the value of the Fund's net
                     assets (including the amount borrowed and the value of
                     any outstanding reverse repurchase agreements) at the
                     time the borrowing is made. Whenever borrowings exceed 5%
                     of the value of the Fund's net assets, the Fund will not
                     make any additional investments;
 
                 (c) pledge, mortgage or hypothecate any of its assets to an
                     extent greater than 5% of its total assets.
 
                 These investment limitations are considered at the time
                 investment securities are purchased. The limitations
                 described here and in the Statement of Additional Information
                 may be changed only with the approval of a majority of the
                 Fund's shareholders.
- ------------------------------------------------------------------------------
MANAGEMENT OF THE FUND
VANGUARD ADMINISTERS AND DISTRIBUTES THE FUND
                 The Fund is a member of The Vanguard Group of Investment
                 Companies, a family of 32 investment companies with 78
                 distinct investment portfolios and total assets in excess of
                 $120 billion. Through their jointly owned subsidiary, The
                 Vanguard Group, Inc. ("Vanguard"), the Fund and the other
                 funds in the Group obtain at cost virtually all of their
                 corporate management, administrative and distribution
                 services. Vanguard also provides investment advisory services
                 on an at-cost basis to certain Vanguard funds. As a result of
                 Vanguard's unique corporate structure, the Vanguard funds
                 have costs substantially lower than those of most competing
                 mutual funds. In 1993, the average expense ratio (annual
                 costs including advisory fees divided by total net assets)
                 for the Vanguard funds amounted to approximately .30%
                 compared to an average of 1.02% for the mutual fund industry
                 (data provided by Lipper Analytical Services).
 
                 Vanguard employs a supporting staff of management and
                 administrative personnel needed to provide the requisite
                 services to the funds and also furnishes the funds with
                 necessary office space, furnishings and equipment. Each fund
                 pays its share of Vanguard's net expenses, which are
                 allocated among the funds under methods approved by the Board
                 of Directors (Trustees) of each fund. In addition, each fund
                 bears its own direct expenses, such as legal, auditing and
                 custodian fees.
 
                 Vanguard provides distribution and marketing services to the
                 funds. The funds are available on a no-load basis (i.e.,
                 there are no sales commissions or 12b-1 fees). However, each
                 fund bears its share of the Group's distribution costs.

INVESTMENT ADVISER
FRANKLIN PORTFOLIO ASSOCIATES MANAGES THE FUND'S INVESTMENTS
                 The Fund employs Franklin Portfolio Associates Trust
                 ("Franklin"), One Post Office Square, Boston, MA 02109, as
                 its investment adviser. Under an investment advisory
                 agreement with the Fund dated October 1, 1987, Franklin
                 manages the investment and reinvestment of the Fund's assets
                 and continuously reviews, supervises, and directs the Fund's
                 investment program. Franklin discharges its responsibilities
                 subject to the control of the Officers and Directors of the
                 Fund.
 
                    Franklin is a professional investment counseling firm
                 which specializes in the management of common stock
                 portfolios through the use of quantitative investment models.
                 Founded in 1982, Franklin, a Massachusetts business trust, is
                 a wholly-owned subsidiary of MBC Investments Corporation. As
                 of December 31, 1993, Franklin provided investment advisory
                 services with respect to approximately $5.12 billion of
                 client assets. Franklin also serves as adviser to
                 approximately one-third of the equity investments of
                 Vanguard/Morgan Growth Fund, another mutual fund member of
                 The Vanguard Group.    
 
                 Franklin employs proprietary computer models in selecting
                 individual equity securities and in structuring investment
                 portfolios for its clients, including the Fund. John J.
                 Nagorniak, President of Franklin, has been designated as the
                 portfolio manager of the Fund, a position he has held since
                 the Fund's inception in December 1986; he is responsible for
                 overseeing the application of Franklin's quantitative
                 techniques to the Fund's assets. Mr. Nagorniak and the other
                 investment principals of Franklin are responsible for the 
                 ongoing development and enhancement of Franklin's 
                 quantitative investment techniques.
 
                 The Fund pays Franklin an advisory fee at the end of each
                 fiscal quarter, calculated by applying a quarterly rate,
                 based on the following annual percentage rates, to the Fund's
                 average month-end net assets for the quarter:
 
                              NET ASSETS                            RATE
                              -----------                            ---
                              First $100 million                    .30%
                              Over $100 million                     .15%
 
                 This fee may be increased or reduced by applying an
                 adjustment formula based on the investment performance of the
                 Fund relative to the S&P 500 Index. For the year ended
                 December 31, 1993, the Fund paid Franklin a basic fee equal
                 to .18 of 1% of its average net assets before an increase of
                 $223,000 (.05 of 1%) based on performance.
 
                 The investment advisory agreement authorizes Franklin to
                 select brokers and dealers to execute purchases and sales of
                 the Fund's portfolio securities, and directs Franklin to use
                 its best efforts to obtain the best available price and most
                 favorable execution with respect to all transactions. The
                 full range and quality of brokerage services are considered
                 in making these determinations.
 
                 The Fund has authorized Franklin to pay higher commissions in
                 recognition of brokerage services felt necessary for the
                 achievement of better execution, provided Franklin believes
                 this to be in the best interest of the Fund. Although the
                 Fund does not market its shares through intermediary brokers,
<PAGE>
                 the Fund may place orders with qualified broker-dealers who
                 recommend the Fund to clients if the Officers of the Fund
                 believe that the quality of the transaction and the
                 commission are comparable to what they would be with other
                 qualified brokerage firms.
 
                 The Fund's Board of Directors may, without the approval of
                 shareholders, provide for: (a) the employment of a new
                 investment adviser pursuant to the terms of a new advisory
                 agreement either as a replacement for an existing adviser or
                 as an additional adviser; (b) a change in the terms of an
                 advisory agreement; and (c) the continued employment of an
                 existing adviser on the same advisory contract terms where a
                 contract has been assigned because of a change in control of
                 the adviser. Any such change will only be made upon not less
                 than 30 days prior written notice to shareholders of the Fund
                 which shall include substantially the information concerning
                 the adviser that would have normally been included in a proxy
                 statement.

PERFORMANCE RECORD
                 The table in this section provides investment results for the
                 Fund for several periods throughout the Fund's lifetime. The
                 results shown represent "total return" investment
                 performance, which assumes the reinvestment of all capital
                 gains and income dividends for the indicated periods. Also
                 included is comparative information with respect to the
                 unmanaged Standard & Poor's 500 Composite Stock Price Index,
                 a widely-used barometer of stock market activity, and the
                 Consumer Price Index, a statistical measure of changes in the
                 prices of goods and services. The tables do not make any
                 allowance for federal, state or local income taxes, which
                 shareholders must pay on a current basis.
 
                 The results shown should not be considered a representation
                 of the total return from an investment made in the Fund
                 today. This information is provided to help investors better
                 understand the Fund and may not provide a basis for
                 comparison with other investments or mutual funds which use a 
                 different method to calculate performance.

DIVIDENDS, CAPITAL GAINS AND TAXES
THE FUND PAYS SEMI-ANNUAL DIVIDENDS AND ANY CAPITAL GAINS ANNUALLY
                 The Fund expects to pay dividends consisting of ordinary
                 income on a semi-annual basis. Capital gains distributions,
                 if any, will be made annually. The Fund is managed without
                 regard to tax ramifications.
 
                 Dividend and capital gains distributions may be automatically
                 reinvested or received in cash. See "Choosing a Distribution
                 Option" for a description of these distribution methods.
 
                 In addition, in order to satisfy certain distribution
                 requirements of the Tax Reform Act of 1986, the Fund may
                 declare special year-end dividend and capital gains
                 distributions during December. Such distributions, if
                 received by shareholders by January 31, are deemed to have
                 been paid by the Fund and received by shareholders on
                 December 31 of the prior year.
 
                 The Fund intends to continue to qualify for taxation as a
                 "regulated investment company" under the Internal Revenue
                 Code so that it will not be subject to federal income tax to
                 the extent its income is distributed to shareholders.
                 Dividends paid by the Fund from net investment income,
                 whether received in cash or reinvested in additional shares,
                 will be taxable to shareholders as ordinary income. For
                 corporate investors, dividends from net investment income
                 will generally qualify in part for the intercorporate
                 dividends-received deduction. However, the portion of the
                 dividends so qualified depends on the aggregate taxable
                 qualifying dividend income received by the Fund from domestic
                 (U.S.) sources.
 
                 Distributions paid by the Fund from long-term capital gains,
                 whether received in cash or reinvested in additional shares,
                 are taxable as long-term capital gains, regardless of the
                 length of time you have owned shares in the Fund. Capital
                 gains distributions are made when the Fund realizes net
                 capital gains on sales of portfolio securities during the
                 year. The Fund does not seek to realize any particular amount
                 of capital gains during a year; rather, realized gains are a
                 byproduct of portfolio management activities. Consequently,
                 capital gains distributions may be expected to vary
                 considerably from year to year; there will be no capital
                 gains distributions in years when the Fund realizes net
                 capital losses.
 
                 Note that if you elect to receive capital gains distributions
                 in cash, instead of reinvesting them in additional shares,
                 you are in effect reducing the capital at work
                 for you in the Fund. Also, keep in mind that if you purchase
                 shares in the Fund shortly before the record date for a
                 dividend or capital gains distribution, a portion of your
                 investment will be paid to you as a taxable distribution,
                 regardless of whether you are reinvesting your distributions
                 or receiving them in cash.
 
                 The Fund will notify you annually as to the tax status of
                 dividend and capital gains distributions paid by the Fund.
 
<PAGE>

A CAPITAL GAIN OR LOSS MAY BE REALIZED UPON EXCHANGE OR REDEMPTION
                 A sale of shares of the Fund is a taxable event and may
                 result in a capital gain or loss. A capital gain or loss may
                 be realized from an ordinary redemption of shares or an
                 exchange of shares between two mutual funds (or two
                 portfolios of a mutual fund).
 
                 Dividend distributions, capital gains distributions, and
                 capital gains or losses from redemptions and exchanges may be
                 subject to state and local taxes.
 
                 The Fund is required to withhold 31% of taxable dividends,
                 capital gains distributions, and redemptions paid to
                 shareholders who have not complied with IRS taxpayer
                 identification regulations. You may avoid this withholding
                 requirement by certifying on your Account Registration Form
                 your proper Social Security or Taxpayer Identification Number
                 and by certifying that you are not subject to backup
                 withholding.
 
                 The Fund has obtained a Certificate of Authority to do
                 business as a foreign corporation in Pennsylvania and does
                 business and maintains an office in that state. In the
                 opinion of counsel, the shares of the Fund are exempt from
                 Pennsylvania personal property taxes.
 
                 The tax discussion set forth above is included for general
                 information only. Prospective investors should consult their
                 own tax advisers concerning the tax consequences of an
                 investment in the Fund.
- ------------------------------------------------------------------------------
THE SHARE PRICE OF THE FUND
                 The Fund's share price or "net asset value" per share is
                 determined by dividing the total market value of the Fund's
                 investments and other assets, less any liabilities, by the
                 number of outstanding shares of the Fund. The net asset value
                 per share is calculated as of the close of regular trading on
                 the New York Stock Exchange (generally 4:00 p.m. Eastern
                 time) on each day that the Exchange is open for business.
 
                 Portfolio securities that are listed on a securities exchange
                 are valued at the last quoted sales price on the day the
                 valuation is made. Price information on listed securities is
                 taken from the exchange where the security is primarily
                 traded. Securities which are listed on an exchange but which
                 are not traded on the valuation date are valued at the mean
                 of the bid and asked prices. Unlisted securities for which
                 market quotations are readily available are valued at the
                 latest quoted bid price. Other assets and securities for
                 which no quotations are readily available are valued at fair
                 value as determined in good faith by the Board of Directors.
                 Securities may be valued on the basis of prices provided by a
                 pricing service when such prices are believed to reflect the
                 fair market value of such securities.
 
                 The Fund's share price can be found daily in the mutual fund
                 listings of most major newspapers under the heading of The
                 Vanguard Group.

GENERAL INFORMATION
                 The Fund is a Maryland corporation. The Articles of
                 Incorporation permit the Directors to issue 1,000,000,000
                 shares of common stock, with a $.001 par value. The Board of
                 Directors has the power to designate one or more classes
                 ("series") of shares of common stock and to classify or
                 reclassify any unissued shares with respect to such series.

                              SHAREHOLDER GUIDE
OPENING AN ACCOUNT AND PURCHASING SHARES
                 You may open a regular (non-retirement) account, either by
                 mail or wire. Simply complete and return an Account
                 Registration Form and any required legal documentation,
                 indicating the amount you wish to invest. Your purchase must
                 be equal to or greater than the $3,000 minimum initial
                 investment requirement ($500 for Uniform Gifts/Transfers to
                 Minors Act accounts). You must open a new Individual
                 Retirement Account by mail (IRAs may not be opened by wire)
                 using a Vanguard IRA Adoption Agreement. Your purchase must
                 be equal to or greater than the $500 minimum initial
                 investment requirement, but no more than $2,000 if you are
                 making a regular IRA contribution. Rollover contributions are
                 generally limited to the amount withdrawn within the past 60
                 days from an IRA or other qualified Retirement Plan. If you
                 need assistance with the forms or have any questions about
                 the Fund, please call our Investor Information Department (1-
                 800-662-7447). NOTE: For other types of account registrations
                 (e.g., corporations, associations, other organizations,
                 trusts or powers of attorney), please call us to determine
                 which additional forms you may need.
 
                 Because of the risks associated with common stock
                 investments, the Fund is intended to be a long-term
                 investment vehicle and is not designed to provide investors
                 with a means of speculating on short-term market movements.
                 Consequently, the Fund reserves the right to reject any
                 specific purchase (and exchange purchase) request. The Fund
                 also reserves the right to suspend the offering of shares for
                 a period of time.
 
                 The Fund's shares are purchased at the next-determined net
                 asset value after your investment has been received. The Fund
                 is offered on a no-load basis (i.e., there are no sales
                 commissions or 12b-1 fees).

ADDITIONAL INVESTMENTS
                 Subsequent investments to regular accounts may be made by
                 mail ($100 minimum), wire ($1,000 minimum), exchange from
                 another Vanguard Fund account ($100 minimum), or Vanguard
                 Fund Express. Subsequent investments to Individual Retirement
                 Accounts may be made by mail ($100 minimum) or exchange from
                 another Vanguard Fund account. In some instances,
                 contributions may be made by wire or Vanguard Fund Express.
                 Please call us for more information on these options.

CHOOSING A DISTRIBUTION OPTION

                 1. AUTOMATIC REINVESTMENT OPTION--Both dividends and capital
                    gains distributions will be reinvested in additional Fund
                    shares. This option will be selected for you automatically
                    unless you specify one of the other options.
 
                 2. CASH DIVIDEND OPTION--Your dividends will be paid in cash
                    and your capital gains will be reinvested in additional
                    Fund shares.
 
                 3. ALL CASH OPTION--Both dividend and capital gains
                    distributions will be paid in cash.
 
                 You may change your option by calling our Client Services
                 Department (1-800-662-2739).
 
                 In addition, an option to invest your cash dividend and/or
                 capital gains distributions in another Vanguard Fund account
                 is available. Please call our Client Services Department (1-
                 800-662-2739) for information. You may also elect Vanguard
                 Dividend Express which allows you to transfer your cash
                 dividends and/or capital gains distributions automatically to
                 your bank account. Please see "Other Vanguard Services" for
                 more information.

TAX CAUTION
INVESTORS SHOULD ASK ABOUT THE TIMING OF CAPITAL GAINS AND DIVIDEND
DISTRIBUTIONS BEFORE INVESTING
                 Under Federal tax laws, the Fund is required to distribute
                 net capital gains and dividend income to Fund shareholders.
                 These distributions are made to all shareholders who own Fund
                 shares as of the distribution's record date, regardless of
                 how long the shares have been owned. Purchasing shares just
                 prior to the record date could have a significant impact on
                 your tax liability for the year. For example, if you purchase
                 shares immediately prior to the record date of a sizable
                 capital gain or income dividend distribution, you will be
                 assessed taxes on the amount of the capital gain and/or
                 dividend distribution later paid even though you owned the
                 Fund shares for just a short period of time. (Taxes are due
                 on the distributions even if the dividend or gain is
                 reinvested in additional Fund shares.) While the total value
                 of your investment will be the same after the
                 distribution--the amount of the distribution will offset the
                 drop in the NAV of the shares--you should be aware of the tax
                 implications the timing of your purchase may have.
 
                 Prospective investors should, therefore, inquire about
                 potential distributions before investing. The Fund's annual
                 capital gains distribution normally occurs in December, while
                 income dividends are generally paid semi-annually in June and
                 December. For additional information on distributions and
                 taxes, see the section titled "Dividends, Capital Gains, and
                 Taxes."

                 signature guarantee verifies the authenticity of your
                 signature and may be obtained from banks, brokers and any
                 other guarantor that Vanguard deems acceptable. A SIGNATURE
                 GUARANTEE CANNOT BE PROVIDED BY A NOTARY PUBLIC.

CERTIFICATES
                 Share certificates will be issued upon request. If a
                 certificate is lost, you may incur an expense to replace it.

BROKER-DEALER PURCHASES
                 If you purchase shares in Vanguard Funds through a registered
                 broker-dealer or investment adviser, the broker-dealer or
                 adviser may charge a service fee.

CANCELLING TRADES
                 The Fund will not cancel any trade (e.g., a purchase,
                 exchange or redemption) believed to be authentic, received in
                 writing or by telephone, once the trade has been received.
- ------------------------------------------------------------------------------
WHEN YOUR ACCOUNT WILL BE CREDITED
                 Your trade date is the date on which your account is
                 credited. If your purchase is made by check, Federal Funds
                 wire or exchange and is received by the close of the New York
                 Stock Exchange (generally 4:00 p.m. Eastern time), your trade
                 date is the day of receipt. If your purchase is received
                 after the close of the Exchange your trade date is the next
                 business day. Your shares are purchased at the net asset
                 value determined on your trade date.
 
                 In order to prevent lengthy processing delays caused by the
                 clearing of foreign checks, Vanguard will only accept a
                 foreign check which has been drawn in U.S. dollars and has
                 been issued by a foreign bank with a U.S. correspondent bank.

                 (1-800-662-7447) for a Fund Express application.
                 -------------------------------------------------------------
SELLING BY EXCHANGE
                 You may sell shares by making an exchange into another
                 Vanguard Fund account. Exchanges may be made only by mail;
                 telephone exchanges are not accepted for the Fund.
                 -------------------------------------------------------------
IMPORTANT REDEMPTION INFORMATION
                 Shares purchased by check or Fund Express may not be redeemed
                 until payment for the purchase is collected, which may take
                 up to ten calendar days. Your money is invested during the
                 holding period.
                 -------------------------------------------------------------
DELIVERY OF REDEMPTION PROCEEDS
                 Redemption requests received by telephone prior to the close
                 of the New York Stock Exchange (generally 4:00 p.m. Eastern
                 time) are processed on the day of receipt and the redemption
                 proceeds are normally sent on the following business day.
 
                 Redemption requests received by telephone after the close of
                 the Exchange are processed on the business day following
                 receipt and the proceeds are normally sent on the second
                 business day following receipt.
 
                 Redemption proceeds must be sent to you within seven days of
                 receipt of your request in Good Order.
 
                 If you experience difficulty in making a telephone redemption
                 during periods of drastic economic or market changes, your
                 redemption request may be made by regular or express mail. It
                 will be implemented at the net asset value next determined
                 after your request has been received by Vanguard in Good
                 Order. The Fund reserves the right to revise or terminate the
                 telephone redemption privilege at any time.
 
<PAGE>
                 The Fund may suspend the redemption right or postpone payment
                 at times when the New York Stock Exchange is closed or under
                 any emergency circumstances as determined by the United
                 States Securities and Exchange Commission.
 
                 If the Board of Directors determines that it would be
                 detrimental to the best interests of the Fund's remaining
                 shareholders to make payment in cash, the Fund may pay
                 redemption proceeds in whole or in part by a distribution
                 in kind of readily marketable securities.
                 -------------------------------------------------------------
VANGUARD'S AVERAGE COST STATEMENT
                 If you make a redemption from a qualifying account, Vanguard
                 will send you an Average Cost Statement which provides you
                 with the tax basis of the shares you redeemed. Please see
                 "Other Vanguard Services" for additional information.
                 -------------------------------------------------------------
MINIMUM ACCOUNT BALANCE REQUIREMENT
                 Due to the relatively high cost of maintaining smaller
                 accounts, the Fund reserves the right to redeem shares in any
                 account that is below the minimum initial investment amount
                 of $3,000. In addition, if at any time your total investment
                 does not have a value of at least $1,000, you may be notified
                 that the value of your account is below the Fund's minimum
                 account balance requirement. You would then be allowed 60
                 days to make an additional investment before the account is
                 liquidated. Proceeds would be promptly paid to the
                 shareholder. This requirement does not apply to IRAs, other
                 retirement accounts, and Uniform Gifts/Transfers to Minors
                 Act accounts.
- ------------------------------------------------------------------------------
EXCHANGING YOUR SHARES
                 Should your investment goals change, you may exchange your
                 shares of Vanguard Quantitative Portfolios for those of other
                 available Vanguard Funds. Exchanges to or from Vanguard
                 Quantitative Portfolios may be made only by mail. TELEPHONE
                 EXCHANGES ARE NOT ACCEPTED FOR THE FUND.

EXCHANGING BY MAIL
                 Please be sure to include on your exchange request the name
                 and account number of your current Fund, the name of the Fund
                 you wish to exchange into, the amount you wish to exchange,
                 and the signatures of all registered account holders. Send
                 your request to VANGUARD FINANCIAL CENTER, VANGUARD
                 QUANTITATIVE PORTFOLIOS, P.O. BOX 1120, VALLEY FORGE, PA
                 19482. (For express or registered mail, send your request to
                 Vanguard Financial Center, Vanguard Quantitative Portfolios,
                 455 Devon Park Drive, Wayne, PA 19087.)
                 -------------------------------------------------------------
IMPORTANT EXCHANGE INFORMATION
                 Before you make an exchange, you should consider the
                 following:
 
                 * Please read the Fund's prospectus before making an
                   exchange. For a copy and for answers to any questions you
                   may have, call our Investor Information Department
                   (1-800-662-7447).
 
                 * An exchange is treated as a redemption and a purchase.
                   Therefore, you could realize a taxable gain or loss on the
                   transaction.
 
                 * Exchanges are accepted only if the registrations and the
                   Taxpayer Identification numbers of the two accounts are
                   identical.
 
                 * The shares to be exchanged must be on deposit and not held
                   in certificate form.
 
<PAGE>
                 * New accounts are not currently accepted in Vanguard/Windsor
                   Fund.

                 * The redemption price of shares redeemed by exchange is the
                   net asset value next determined after Vanguard has received
                   all required documentation in Good Order.

                 * When opening a new account by exchange, you must meet the
                   minimum investment requirement of the new Fund.

                 Every effort will be made to maintain the exchange privilege.
                 However, the Fund reserves the right to revise or terminate
                 its provisions, limit the amount of or reject any exchange,
                 as deemed necessary, at any time.
- ------------------------------------------------------------------------------
 
EXCHANGE PRIVILEGE LIMITATIONS
                 The Fund's exchange privilege is not intended to afford
                 shareholders a way to speculate on short-term movements in
                 the market. Accordingly, in order to prevent excessive use of
                 the exchange privilege that may potentially disrupt the
                 management of the Fund and increase transaction costs, the
                 Fund has established a policy of limiting excessive exchange
                 activity.

                 Exchange activity generally will not be deemed excessive if
                 limited to TWO SUBSTANTIVE EXCHANGE REDEMPTIONS (AT LEAST 30
                 DAYS APART) from the Fund during any twelve month period.
                 Notwithstanding these limitations, the Fund reserves the
                 right to reject any purchase request (including exchange
                 purchases from other Vanguard portfolios) that is reasonably
                 deemed to be disruptive to efficient portfolio management.
- ------------------------------------------------------------------------------
IMPORTANT INFORMATION ABOUT TELEPHONE TRANSACTIONS
                 The ability to initiate redemptions (except wire redemptions)
                 by telephone is automatically established on your account
                 unless you request in writing that telephone transactions on
                 your account not be permitted.

                 To protect your account from losses resulting from
                 unauthorized or fraudulent telephone instructions, Vanguard
                 adheres to the following security procedures:

                 1. SECURITY CHECK. To request a transaction by telephone, the
                    caller must know (i) the name of the Portfolio; (ii) the
                    10-digit account number; (iii) the exact name in which the
                    account is registered; and (iv) the Social Security or
                    Taxpayer Identification number listed on the account.

                 2. PAYMENT POLICY. The proceeds of any telephone redemption
                    by mail will be made payable to the registered shareowner
                    and mailed to the address of record, only.

                 Neither the Fund nor Vanguard will be responsible for the
                 authenticity of transaction instructions received by
                 telephone, provided that reasonable security procedures have
                 been followed. Vanguard believes that the security procedures
                 described above are reasonable and that if such procedures
                 are followed, you will bear the risk of any losses resulting
                 from unauthorized or fraudulent telephone transactions on
                 your account. If Vanguard fails to follow reasonable security
                 procedures, it may be liable for any losses resulting from
                 unauthorized or fraudulent telephone transactions on your
                 account.

FUTURES CONTRACTS
  The Fund may enter into futures contracts, options, and options on futures
contracts for the purpose of simulating full investment and reducing
transactions costs. Futures contracts provide for the future sale by one party
and purchase by another party of a specified amount of a specific security at
a specified future time and at a specified price. Futures contracts which are
standardized as to maturity date and underlying financial instrument are
traded on national futures exchanges. Futures exchanges and trading are
regulated under the Commodity Exchange Act by the Commodity Futures Trading
Commission ("CFTC"), a U.S. Government Agency.
  Although futures contracts by their terms call for actual delivery or
acceptance of the underlying securities, in most cases the contracts are
closed out before the settlement date without the making or taking of
delivery. Closing out an open futures position is done by taking an opposite
position ("buying" a contract which has previously been "sold," or "selling" a
contract previously purchased) in an identical contract to terminate the
position. Brokerage commissions are incurred when a futures contract is bought
or sold.
  Futures traders are required to make a good faith margin deposit in cash or
government securities with a broker or custodian to initiate and maintain open
positions in futures contracts. A margin deposit is intended to assure
completion of the contract (delivery or acceptance of the underlying security)
if it is not terminated prior to the specified delivery date. Minimal initial
margin requirements are established by the futures exchange and may be
changed. Brokers may establish deposit requirements which are higher than the
exchange minimums. Futures contracts are customarily purchased and sold which
may range upward from less than 5% of the value of the contract being traded.
  After a futures contract position is opened, the value of the contract is
marked to market daily. If the futures contract price changes to the extent
that the margin on deposit does not satisfy margin requirements, payment of
additional "variation" margin will be required. Conversely, change in the
contract value may reduce the required margin, resulting in a repayment of
excess margin to the contract holder. Variation margin payments are made to
and from the futures broker for as long as the contract remains open. The Fund
expects to earn interest income on its margin deposits.
 
<PAGE>
  Traders in futures contracts may be broadly classified as either "hedgers"
or "speculators." Hedgers use the futures markets primarily to offset
unfavorable changes in the value of securities otherwise held for investment
purposes or expected to be acquired by them. Speculators are less inclined to
own the securities underlying the futures contracts which they trade, and use
futures contracts with the expectation of realizing profits from fluctuations
in the prices of underlying securities. The Fund intends to use futures
contracts only for bonafide hedging purposes.
  Regulations of the CFTC applicable to the Fund require that all of its
futures transactions constitute bonafide hedging transactions. The Fund will
only sell futures contracts to protect securities it owns against price
declines or purchase contracts to protect against an increase in the price of
securities it intends to purchase. As evidence of this hedging interest, the
Fund expects that approximately 75% of its futures contract purchases will be
"completed," that is, equivalent amounts of related securities will have been
purchased or are being purchased by the Fund upon sale of open futures
contracts.
  Although techniques other than the sale and purchase of futures contracts
could be used to control the Fund's exposure to market fluctuations, the use
of futures contracts may be a more effective means of hedging this exposure.
While the Fund will incur commission expenses in both opening and closing out
futures positions, these costs are lower than transaction costs incurred in
the purchase and sale of the underlying securities.
 
RESTRICTIONS ON THE USE OF FUTURES CONTRACTS
  The Fund will not enter into futures contract transactions to the extent
that, immediately thereafter, the sum of its initial margin deposits on open
contracts exceeds 5% of the market value of the Fund's total assets. In
addition, the Fund will not enter into futures contracts to the extent that
its outstanding obligations to purchase securities under these contracts would
exceed 20% of the Fund's total assets.
 
RISK FACTORS IN FUTURES TRANSACTIONS
  Positions in futures contracts may be closed out only on an Exchange which
provides a secondary market for such futures. However, there can be no
assurance that a liquid secondary market will exist for any particular futures
contract at any specific time. Thus, it may not be possible to close a futures
position. In the event of adverse price movements, the Fund would continue to
be required to make daily cash payments to maintain its required margin. In
such situations, if the Fund has insufficient cash, it may have to sell
portfolio securities to meet daily margin requirements at a time when it may
be disadvantageous to do so. In addition, the Fund may be required to make
delivery of the instruments underlying futures contracts it holds. The
inability to close options and futures positions also could have an adverse
impact on the ability to effectively hedge it.
  The Fund will minimize the risk that it will be unable to close out a
futures contract by only entering into futures which are traded on national
futures exchanges and for which there appears to be a liquid secondary market.
  The risk of loss in trading futures contracts in some strategies can be
substantial, due both to the low margin deposits required, and the extremely
high degree of leverage involved in futures pricing. As a result, a relatively
small price movement in a futures contract may result in immediate and
substantial loss (as well as gain) to the investor. For example, if at the
time of purchase, 10% of the value of the futures contract is deposited as
margin, a subsequent 10% decrease in the value of the futures contract would
result in a total loss of the margin deposit, before any deduction for the
transaction costs, if the account were then closed out. A 15% decrease would
result in a loss equal to 150% of the original margin deposit if the contract
were closed out. Thus, a purchase or sale of a futures contract may result in
losses in excess of the amount invested in the contract. Additionally, the
Fund bears the risk that the Advisor will incorrectly predict future market
trends. However, because the futures strategies of the Fund are engaged in
only for hedging purposes, the Adviser does not believe that the Fund is
subject to the risks of loss frequently associated with futures transactions.
The Fund would presumably have sustained comparable losses if, instead of the
futures contract, it had invested in the underlying security and sold it after
the decline.
  Utilization of futures transactions by the Fund does involve the risk of
imperfect or no correlation where the securities underlying futures contracts
are different than the portfolio securities being hedged. It is also possible
that the Fund could both lose money on futures contracts and also experience a
decline in value of its portfolio securities. There is also the risk of loss
by the fund of margin deposits in the event of bankruptcy of a broker with
whom the Fund has an open position in a futures contract or related option.
Additionally,
<PAGE>
investments in futures contracts and options involve the risk that the
investment adviser will incorrectly predict stock market trends.
  Most futures exchanges limit the amount of fluctuation permitted in futures
contract prices during a single trading day. The daily limit establishes the
maximum amount that the price of a futures contract may vary either up or down
from the previous day's settlement price at the end of a trading session. Once
the daily limit has been reached in a particular type of contract, no trades
may be made on that day at a price beyond that limit. The daily limit governs
only price movement during a particular trading day and therefore does not
limit potential losses, because the limit may prevent the liquidation of
unfavorable positions. Futures contract prices have occasionally moved to the
daily limit for several consecutive trading days with little or no trading,
thereby preventing prompt liquidation of future positions and subjecting some
futures traders to substantial losses.
 
FEDERAL TAX TREATMENT OF FUTURES CONTRACTS
  Except for transactions the Fund has identified as hedging transactions, the
Fund is required for federal income tax purposes to recognize as income for
each taxable year its net unrealized gains and losses on certain futures
contracts as of the end of the year as well as those actually realized during
the year. In most cases, any gain or loss recognized with respect to a futures
contract is considered to be 60% long-term capital gain or loss and 40% short-
term capital gain or loss, without regard to the holding period of the
contract. Furthermore, sales of futures contracts which are intended to hedge
against a change in the value of securities held by the Fund may affect the
holding period of such securities and, consequently, the nature of the gain or
loss on such securities upon disposition.
  In order for the Fund to continue to qualify for federal income tax
treatment as a regulated investment company, at least 90% of its gross income
for a taxable year must be derived from qualifying income; i.e., dividends,
interest, income derived from loans of securities, and gains from the sale of
securities. In addition, gains realized on the sale or other disposition of
securities held for less than three months must be limited to less than 30% of
the Fund's annual gross income. Any net gain realized from the closing out of
futures contracts will be considered gain from the sale of securities and
therefore be qualifying income for purposes of the 90% requirement. In order
to avoid realizing excessive gains on securities held less than three months,
the Portfolio may be required to defer the closing out of futures contracts
beyond the time when it would otherwise be advantageous to do so. It is
anticipated that unrealized gains on futures contracts, which have been open
for less than three months as of the end of the Portfolio's fiscal year and
which are recognized for tax purposes, will not be considered gains on sales
of securities held less than three months for the purpose of the 30% test.
  The Fund will distribute to shareholders annually any net capital gains
which have been recognized for federal income tax purposes (including
unrealized gains at the end of the Portfolio's fiscal year) on futures
transactions. Such distributions will be combined with distributions of
capital gains realized of the Portfolio's other investments and shareholders
will be advised of the nature of the distributions.
 
REPURCHASE AGREEMENTS
  The Fund may invest in repurchase agreements with commercial banks, brokers
or dealers to generate net investment income from its excess cash balances. A
repurchase agreement is an agreement under which the Fund acquires a money
market instrument (generally a security issued by the U.S. Government or an
agency thereof, a banker's acceptance or a certificate of deposit) from a
Federal Reserve member bank with minimum assets of at least $2 billion or a
registered securities dealer, subject to resale to the seller at an agreed
upon price and date (normally, the next business day). A repurchase agreement
may be considered a loan collaterized by securities. The resale price reflects
an agreed upon interest rate effective for the period the instrument is held
by the Fund and is unrelated to the interest rate on the underlying
instrument. In these transactions, the securities acquired by the Fund
(including accrued interest earned thereon) must have a total value in excess
of the value of the repurchase agreement and are held by the Fund's custodian
bank until repurchased. The Fund's Board of Directors will monitor the Fund's
repurchase agreement transactions and will establish guidelines and standards
for review of the creditworthiness of any bank, broker or dealer party to a
repurchase agreement with the Fund. No more than an aggregate of 15% of the
Fund's net assets, at the time of investment, will be invested in repurchase
agreements having maturities longer than seven days and
<PAGE>
securities subject to legal or contractual restrictions on resale, or for
which there are no readily available market quotations.
  The use of repurchase agreements involves certain risks. For example, if the
other party to the agreement defaults on its obligation to repurchase the
underlying security at a time when the value of the security has declined, the
Fund may incur a loss upon disposition of the security. If the other party to
the agreement becomes insolvent and subject to liquidation or reorganization
under the Bankruptcy Code or other laws, a court may determine that the
underlying security is collateral for a loan by the Fund not within the
control of the Fund and therefore the Fund may not be able to substantiate its
interest in the underlying security and may be deemed an unsecured creditor of
the other party to the agreement. While the Fund's management acknowledges
these risks, it is expected that they can be controlled through careful
monitoring procedures.
 
LENDING OF SECURITIES
  The Fund may lend its securities to qualified institutional investors who
need to borrow securities in order to complete certain transactions, such as
covering short sales, avoiding failures to deliver securities or completing
arbitrage operations. By lending its portfolio securities, the Fund attempts
to increase its net investment income through the receipt of interest on the
loan. Any gain or loss in the market price of the securities loaned that might
occur during the term of the loan would be for the account of the Fund. The
Fund may lend its portfolio securities to qualified brokers, dealers, banks or
other financial institutions, so long as the terms, the structure and the
aggregate amount of such loans are not inconsistent with the Investment
Company Act of 1940, or the Rules and Regulations or interpretations of the
Securities and Exchange Commission (the "Commission") thereunder, which
currently require that (a) the borrower pledge and maintain with the Fund
collateral consisting of cash, a letter of credit issued by a domestic U.S.
bank, or securities issued or guaranteed by the United States Government
having at all times not less than 100% of the value of the securities loaned,
(b) the borrower add to such collateral whenever the price of the securities
loaned rises (i.e. the borrower "marks to the market" on a daily basis), (c)
the loan be made subject to termination by the Fund at any time and (d) the
Fund receive reasonable interest on the loan (which may include the Fund's
investing any cash collateral in interest bearing short-term investments), any
distribution on the loaned securities and any increase in their market value.
Loan arrangements made by the Fund will comply with all other applicable
regulatory requirements, including the rules of the New York Stock Exchange,
which rules presently require the borrower, after notice, to redeliver the
securities within the normal settlement time of five business days. All
relevant facts and circumstances, including the creditworthiness of the
broker, dealer or institution, will be considered in making decisions with
respect to the lending of securities, subject to review by the Fund's Board of
Directors.
  At the present time, the Staff of the Commission does not object if an
investment company pays reasonable negotiated fees in connection with loaned
securities, so long as such fees are set forth in a written contract and
approved by the investment company's Directors. In addition, voting rights may
pass with the loaned securities, but if a material event will occur affecting
an investment on loan, the loan must be called and the securities voted.
 
                            INVESTMENT LIMITATIONS
 
  The following restrictions are fundamental policies and cannot be changed
without approval of the holders of a majority of the outstanding shares of the
Fund or, if less, 67% of the shares represented at a meeting of shareholders
at which the holders of 50% or more of the shares are represented. The Fund
may not under any circumstances:
   1) Invest for the purpose of exercising control of management of any
      company;
   2) With respect to 75% of the value of its total assets, purchase the
      securities of any issuer (except obligations of the United States
      government and its instrumentalities) if as a result the Fund would hold
      more than 10% of the outstanding voting securities of the issuer, or
      more than 5% of the value of the Fund's total assets would be invested
      in the securities of such issuer;
   3) Invest in securities of other investment companies, except as may be
      acquired as part of a merger, consolidation or acquisition of assets
      approved by the Fund's shareholders or otherwise to the extent permitted
      by Section 12 of the Investment Company Act of 1940. The Fund will
      invest only in investment companies which have investment objectives and
      investment policies consistent with those of the Fund;
 
<PAGE>
   4) Engage in the business of underwriting securities issued by other
      persons, except to the extent that the Fund may technically be deemed to
      be an underwriter under the Securities Act of 1933, as amended, in
      disposing of investment securities;
   5) Purchase or otherwise acquire any security if, as a result more than 15%
      of its net assets would be invested in securities that are illiquid
      (including the Fund's investment in The Vanguard Group, Inc.);
   6) Borrow money, except that the Fund may borrow from banks (or through
      reverse repurchase agreements), for temporary or emergency (not
      leveraging) purposes, including the meeting of redemption requests which
      might otherwise require the untimely disposition of securities, in an
      amount not exceeding 10% of the value of the Fund's net assets
      (including the amount borrowed and the value of any outstanding reverse
      repurchase agreements) at the time the borrowing is made. Whenever
      borrowings exceed 5% of the value of the Fund's net assets, the Fund
      will not make any additional investments;
   7) Invest in commodities or real estate although the Fund may use stock
      futures contracts or options for hedging purposes only, and provided
      that not more than 5% of the Funds assets are required as futures
      contract deposit and not more than 20% of the Fund's assets are
      committed to futures contracts and options transactions, and, may
      purchase and sell securities of companies which deal in real estate, or
      interests therein;
   8) Purchase securities on margin or sell any securities short, except that
      the Fund may invest in futures contracts and options transactions as set
      forth above;
   9) Purchase or retain any security if (i) one or more officers, trustees or
      partners of the Fund or its investment adviser individually own or would
      own, directly or beneficially, more than 1/2 of 1 per cent of the
      securities of such issuer, and (ii) in the aggregate such persons own or
      would own more than 5% of such securities;
  10) Make loans except (i) by purchasing bonds, debentures or similar
      obligations (including repurchase agreements, subject to the limitation
      described in (5) above) which are publicly distributed, and (ii) by
      lending its securities to banks, brokers, dealers and other financial
      institutions so long as such loans are not inconsistent with the
      Investment Company Act or the Rules and Regulations or interpretations
      of the Securities and Exchange Commission thereunder.
  11) Pledge, mortgage, or hypothecate any of its assets to an extent greater
      than 5% of its total assets;
  12) Invest directly in interests in oil, gas or other mineral exploration or
      development programs; and
  13) Invest more than 25% of the value of its total assets in any one
      industry.
  14) Purchase or sell options or warrants or engage in arbitrage operations.
  The above-mentioned investment limitations are considered at the time the
investment securities are purchased. Notwithstanding these limitations, the
Fund may own all or any portion of the securities of, or make loans to, or
contribute to the costs or other financial requirements of any company which
will be wholly owned by the Fund and one or more other investment companies
and is primarily engaged in the business of providing, at-cost, management,
administrative, distribution or related services to the Fund and other
investment companies. See "The Vanguard Group." As a non-fundamental policy,
the Fund will not invest more than 5% of its total assets in the securities of
companies that, together with their predecessors, have been in continuous
operation for less than three years.
 
                            YIELD AND TOTAL RETURN
 
  The yield of the Fund for the 30 day period ended December 31, 1993 was
2.23%.
  The average annual total return of the Fund for the 1, 3, and 5 year periods
ended December 31, 1993 and, since its inception on December 10, 1986 was
+13.83%, +16.64%, +15.37% and +13.25% respectively. Total return is computed
by finding the average compounded rates of return over the one year and since
inception periods set forth above that would equate an initial amount invested
at the beginning of the periods to the ending redeemable value of the
investment.
 
                              PURCHASE OF SHARES
 
  The Fund reserves the right in its sole discretion (i) to suspend the
offerings of its shares, (ii) to reject purchase orders when in the judgement
of management such rejection is in the best interest of the Fund, and
<PAGE>
(iii) to reduce or waive the minimum for initial and subsequent investments
for certain fiduciary accounts or under circumstances where certain economies
can be achieved in sales of the Fund's shares.
 
                             REDEMPTION OF SHARES
 
  The Fund may suspend redemption priviledges or postpone the date of payment
(i) during any period that the New York Stock Exchange is closed, or trading
on the Exchange is restricted as determined by the Securities and Exchange
Commission (the "Commission"), (ii) during any period when an emergency exists
as defined by the rules of the Commission as a result of which it is not
reasonably practicable for the Fund to dispose of securities owned by it, or
fairly to determine the value of its assets, and (iii) for such other periods
as the Commission may permit.
  No charge is made by the Fund for redemptions. Any redemption may be more or
less than the shareholder's cost depending on the market value of the
securities held by the Fund.
  The Fund has made an election with the Commission to pay in cash all
redemptions requested by any shareholder of record limited in amount during
any 90-day period to the lesser of $250,000 or 1% of the net assets of the
Fund at the beginning of such period. Such commitment is irrevocable without
the prior approval of the Commission. Redemptions in excess of the above
limits may be paid in whole or in part, in investment securities or in cash,
as the Directors may deem advisable; however, payment will be made wholly in
cash unless the Directors believe that economic or market conditions exist
which would make such a practice detrimental to the best interests of the
Fund. If redemptions are paid in investment securities, such securities will
be valued as set forth in the Prospectus under "The Fund's Share Price" and a
redeeming shareholder would normally incur brokerage expenses if he converted
these securities to cash.
 
                             SHAREHOLDER SERVICES
 
EXCHANGE PRIVILEGE
  Shares of the Fund may be exchanged without cost for shares of any open-end
Fund in The Vanguard Group offering its shares to new investors. A shareholder
of any other open-end Fund in The Vanguard Group may likewise exchange his
shares for shares of the Fund. Exchange requests may be made by writing to
Vanguard.
  Any such exchange will be based on the respective net asset values of the
shares involved. Before making an exchange, a shareholder should consider the
investment objectives and policies of the Fund to be purchased, and other
relevant information (including the minimum initial investment), which can be
found in that Fund's prospectus. A prospectus for any of the Vanguard Funds
may be obtained from Vanguard.
  For Federal income tax purposes, an exchange between Funds is a taxable
event and, accordingly, a capital gain or loss may be realized. The exchange
priviledge may be modified or terminated at any time, and any of the Vanguard
Funds may limit or discontinue the offering of its shares without notice to
shareholders.
 
INFORMATION FOR SHAREHOLDERS
  Following any purchase or redemption, a shareholder will receive a statement
which reflects all activity during the current calendar year. Each shareholder
will also receive a monthly statement, which includes a valuation as of the
day the statement is prepared.
  Semi-annual reports and annual audited reports, which include the list of
investments held by the Fund, will be sent to shareholders.
 
                            MANAGEMENT OF THE FUND
 
OFFICERS AND DIRECTORS
  The Fund's officers, under the supervision of the Board of Directors, manage
the day to day operations of the Fund. The Directors, who are elected annually
by shareholders, set broad policies for the Fund and choose its officers. A
list of the Directors and officers of the Fund and a brief statement of their
present positions and principal occupations during the past 5 years is set
forth in the Prospectus.
 
THE VANGUARD GROUP
  Vanguard Quantitative Portfolios, Inc. is a member of The Vanguard Group of
Investment Companies. Through their jointly-owned subsidiary, The Vanguard
Group, Inc. ("Vanguard"), the Fund and the other
<PAGE>
Funds in the Group obtain at cost virtually all of their corporate management,
administrative and distribution services. Vanguard also provides investment
advisory services on an at-cost basis to several of the Vanguard Funds.
  Vanguard employs a supporting staff of management and administrative
personnel needed to provide the requisite services to the Funds and also
furnishes the Funds with necessary office space, furnishings and equipment.
Each Fund pays its share of Vanguard's net expenses which are allocated among
the Funds under methods approved by the Board of Directors (Trustees) of each
Fund. In addition, each Fund bears its own direct expenses such as legal,
auditing and custodian fees.
  The Fund's officers are also officers and employees of Vanguard. No officer
or employee owns, or is permitted to own, any securities of any external
adviser for the Funds.
  The Vanguard Group was established and operates under a Fund's Service
Agreement which was approved by the shareholders of each of the Funds. The
amounts of which each of the Funds have invested are adjusted from time to
time in order to maintain the proportionate relationship between each Fund's
relative net assets and its contribution to Vanguard's capital. At December
31, 1993, the Fund had contributed capital of $85,000 to Vanguard,
representing .4% of Vanguard's capitalization. The Fund's Service Agreement
was amended on May 10, 1993 to provide as follows: (a) each Vanguard Fund may
invest up to .40% of its current assets in Vanguard, and (b) there is no other
limitation on the amount that each Vanguard Fund may contribute to Vanguard's
capitalization.
  MANAGEMENT. Corporate management and administrative services include: (1)
executive staff; (2) accounting and financial; (3) legal and regulatory; (4)
shareholder account maintenance; (5) monitoring and control of custodian
relationships; (6) shareholder reporting; and (7) review and evaluation of
advisory and other services provided to the Funds by third parties. During the
fiscal year ended December 31, 1993, the Fund's share of Vanguard's actual net
costs of operation relating to management and administrative services
(including transfer agency) totaled approximately $1,039,000.
  DISTRIBUTION. Vanguard provides all distribution and marketing activities
for the Funds in the Group. Vanguard Marketing Corporation, a wholly-owned
subsidiary of Vanguard, acts as Sales Agent for the shares of the Funds in
connection with any sales made directly to investors in the states of Florida,
Missouri, New York, Ohio, Texas and such other states as it may be required.
  The principal distribution expenses are for advertising, promotional
materials and marketing personnel. Distribution services may also include
organizing and offering to the public, from time to time, one or more new
investment companies which will become members of the Group. The Directors and
officers of Vanguard determine the amount to be spent annually on distribution
activities, the manner and amount to be spent on each Fund, and whether to
organize new investment companies.
  One-half of the distribution expenses of a marketing and promotional nature
is allocated among the Funds based upon relative net assets. The remaining
one-half of those expenses is allocated among the Funds based upon each Fund's
sales for the preceding 24 months relative to the total sales of the Funds as
a Group, provided, however, that no Fund's aggregate quarterly rate of
contribution for distribution expenses of a marketing and promotional nature
shall exceed 125% of average distribution expense rate for the Group, and that
no Fund shall incur annual distribution expenses in excess of 20/100 of 1% of
its average month-end net assets. During the year ended December 31, 1993 the
Fund paid approximately $109,000 of the Group's distribution and marketing
expenses which represented an effective annual rate of .02 of 1% of the Fund's
average net assets.
  REMUNERATION OF DIRECTORS (TRUSTEES) AND OFFICERS. The Fund pays each
Director (Trustee), who is not also an officer, an annual fee plus travel and
other expenses incurred in attending Board meetings. For the year ended
December 31, 1993, the Fund paid approximately $1,000 in directors' fees and
expenses. The Fund's officers and employees are paid by Vanguard which, in
turn, is reimbursed by the Fund, and each other Fund in the Group, for its
proportionate share of officers' and employees' salaries and retirement
benefits. During the year ended December 31, 1993 the Fund's proportionate
share of remuneration, paid by Vanguard (and reimbursed by the Fund) was
approximately $20,506.
  Directors who are not officers receive no retirement benefits. Under its
retirement plan, Vanguard contributes annually an amount equal to 10% of each
officer's annual compensation plus 5.7% of that part of the eligible officer's
compensation during the year, if any, that exceeds the Social Security Taxable
Wage Base then in effect. Under its thrift plan, all eligible officers are
permitted to make pre-tax contributions in an amount equal to 4% of total
compensation which are matched by Vanguard on a 100% basis. The fee is equal
<PAGE>
to $1,000 for each year of service on the board up to fifteen years of
service, upon retirement. The fee is equal to $1,000 for each year of service
and each investment company member of The Vanguard Group contributes a
proportionate amount of this fee based on its relative net assets. The fee is
paid subsequent to a Director's Retirement for a period of ten years or until
the death of a retired director. The Fund's proportionate share of retirement
contributions made by Vanguard under its retirement and thrift plans on behalf
of all eligible officers of the Fund, as a group, during the 1993 fiscal year
was approximately $2,455.
 
                         INVESTMENT ADVISORY SERVICES
 
  The Fund employs Franklin Portfolio Associates Trust ("Franklin") under an
advisory agreement dated October 1, 1987 to manage the investment and
reinvestment of the Fund's assets and to continuously review, supervise and
administer the Fund's investment program. Franklin discharges its
responsibilities subject to control of the officers and Directors of the Fund.
  The Fund pays Franklin a fee at the end of each fiscal quarter, calculated
by applying a quarterly rate, based on the following annual percentage rates,
to the Fund's average month-end net assets for the quarter:
 
     NET ASSETS                                                      RATE
     -------                                                         ----
     First $100 million...........................................  0.30%
     Over $100 million............................................  0.15%
 
  The Basic Fee paid to Franklin may be increased or decreased by applying an
adjustment formula based on the Fund's investment performance. Such formula
provides for an increase or decrease in the Basic Fee in an amount equal to
.20% per annum (.05% per quarter) of the first $100 million of average month
end net assets of the Fund, and .10% per annum (.025% per quarter) of average
month-end net assets over $100 million, if the Fund's investment performance
for the thirty-six months preceding the end of the quarter is six percentage
points or more above or below, respectively, the investment record of the
Standard & Poor's Daily Stock Price Index of 500 Common Stocks (the "S&P
Index") for the same period; or by an amount equal to .10% per annum (.025%
per quarter) of the first $100 million of average month-end net assets and
.05% per annum (.0125% per quarter) of average month-end net assets over $100
million if the Fund's investment performance for such thirty-six months is
three or more but less than six percentage points above or below,
respectively, the investment record of the S&P Index for the same period.
  For example, if the average net assets of the Fund were $100 million or
less, and its investment performance for the preceding three year period was
more than six percentage points above the S&P Index, the total fee would be
0.50% of average net assets, consisting of the Basic fee of 0.30%, and an
incentive fee of 0.20%. Conversely, if performance were six percentage points
below the S&P, the total fee would be 0.10% of net assets -- the Basic Fee of
0.30%, adjusted for a penalty of 0.20%. Above assets levels of $100 million,
both the Basic Fee and the Incentive Fee are reduced, as described above.
  The present agreement continues until September 30, 1994. The agreement is
renewable thereafter, for successive one year periods, only if each renewal is
specifically approved by a vote of the Fund's Board of Directors, including
the affirmative votes of a majority of the Directors who are not parties to
the contract of "interested persons" (as defined in the Investment Company Act
of 1940) of any such party, cast in person at a meeting called for the purpose
of considering such approval. In addition, the question of continuance of the
agreement may be presented to the shareholders of the Fund; in such event
continuance shall be effected only if approved by the affirmative vote of a
majority of the outstanding voting securities of the Fund. The agreement is
automatically terminated if assigned, and may be terminated without penalty at
any time (1) either by vote of the Board of Directors of the Fund or by vote
of the Fund's outstanding voting securities on 60 days' written notice to
Franklin, or (2) by Franklin upon 90 days' written notice to the Fund.
  The Fund's Board of Directors may, without the approval of shareholders,
provide for:
  A. The employment of a new investment adviser pursuant to the terms of a new
advisory agreement, either as a replacement for an existing adviser or as an
additional adviser.
  B. A change in the terms of an advisory agreement.
  C. The continued employment of an existing adviser on the same advisory
contract terms where a contract has been assigned because of a change in
control of the adviser.
 
<PAGE>
  Any such change will only be made upon not less than 30 days' prior written
notice to shareholders, which shall include the information concerning the
adviser that would have normally been included in a proxy statement.
  During the years ended December 31, 1991, 1992 and 1993, the Fund paid
investment advisory fees of approximately $578,000, $706,000, and $852,000.
For the fiscal year ended December 31, 1993 the Fund paid $223,000 for
performance adjustments.
  DESCRIPTION OF FRANKLIN. Franklin is a Delaware corporation and is a wholly-
owned subsidiary of Mellon Financial Services Corporation #1.
 
                            PORTFOLIO TRANSACTIONS
 
  The investment advisory agreement authorizes the Adviser (with the approval
of the Fund's Board of Directors) to select the brokers or dealers that will
execute the purchases and sales of portfolio securities for the Fund and
directs the Adviser to use its best efforts to obtain the best available price
and most favorable execution as to all transactions for the Fund. The Adviser
has undertaken to execute each investment transaction at a price and
commission which provides the most favorable total cost or proceeds reasonably
obtainable under the circumstances.
  In placing portfolio transactions, the Adviser will use its best judgement
to choose the broker most capable of providing the brokerage services
necessary to obtain best available price and most favorable execution. The
full range and quality of brokerage services available will be considered in
making these determinations. In those instances where it is reasonably
determined that more than one broker can offer the brokerage services needed
to obtain the best available price and most favorable execution, consideration
may be given to those brokers which supply investment research and statistical
information and provide other services in addition to execution services to
the Fund and/or the Adviser. The Adviser considers such information useful in
the performance of its obligations under the agreement, but is unable to
determine the amount by which such services may reduce its expenses.
  The investment advisory agreement also incorporates the concepts of Section
28(e) of the Securities Exchange Act of 1934 by providing that, subject to the
approval of the Fund's Board of Directors, the Adviser may cause the Fund to
pay a broker-dealer which furnishes brokerage and research services a higher
commission than that which might be charged by another broker-dealer for
effecting the same transaction; provided that such commission is deemed
reasonable in terms of either that particular transaction or the overall
responsibilities of the Adviser to the Fund.
  Currently, it is the Fund's policy that the Adviser may at times pay higher
commissions in recognition of brokerage services felt necessary for the
achievement of better execution of certain securities transactions that
otherwise might not be available. The Adviser will only pay such higher
commissions if it believes this to be in the best interest of the Fund. Some
brokers or dealers who may receive such higher commissions in recognition of
brokerage services related to execution of securities transactions are also
providers of research information to the Adviser and/or the Fund. However, the
Adviser has informed the Fund that it will not pay higher commission rates
specifically for the purpose of obtaining research services.
  Since the Fund does not market its shares through intermediary brokers or
dealers, it is not the Fund's practice to allocate brokerage or principal
business on the basis of sales of its shares which may be through such firms.
However, the Fund may place portfolio orders with qualified broker-dealers who
recommend the Fund to other clients, or who act as agent in the purchase of
the Fund's shares for their clients, and may, when a number of brokers and
dealers can provide comparable best price and execution on a particular
transaction, consider the sale of the Fund shares by a broker or dealer in
selecting among qualified broker-dealers.
  Some securities considered for investment by the Fund may also be
appropriate for other clients served by the Adviser. If purchase or sale of
securities consistent with the investment policies of the Fund and one or more
of these other clients services by the Adviser are considered at or about the
same time, transactions in such securities will be allocated among the Fund
and such other clients in a manner deemed equitable by the Adviser. During the
years ended December 31, 1991, 1992 and 1993 the Fund paid $264,080, $478,691,
and $511,942 in brokerage commissions, respectively.

DESCRIPTION OF SHARES AND VOTING RIGHTS
  The Fund is a diversified open-ended investment company established under
Maryland law under Amended and Restated Articles of Incorporation dated
September 2, 1986 which permit the Directors to issue 1,000,000,000 shares of
common stock, with a $.001 par value. The Board of Directors has the power to
designate one or more classes ("portfolios") of shares of common stock and to
classify or reclassify any unissued shares with respect to such Portfolios.
Currently the Fund is offering shares of one Portfolio.
  The shares of each Portfolio are fully paid and non-assessable, and have no
preference as to conversion, exchange, dividends, retirement or other
features. The shares have no pre-emptive rights. The shares have non-
cumulative voting rights, which means that the holders of more than 50% of the
shares voting for the election of Directors can elect 100% of the Directors if
they choose to do so. A shareholder is entitled to one vote for each full
shares held (and a fractional vote for each fractional share held), then
standing in his name on the books of the Fund. On any matter submitted to a
vote of shareholders, all shares of the Fund then issued and outstanding and
entitled to vote, irrespective of the class, shall be voted in the aggregate
and not be class except (i) when required by the Investment Company Act of
1940, shares shall be voted by individual class, and (ii) when the matter does
not affect any interest of a particular class, then only shareholders of the
affected class or classes shall be entitled to vote thereon.
