Example

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you were to invest $10,000 in the Fund's shares. This example assumes that the Fund provides a return of 5% each year and that total annual fund operating expenses remain as stated in the preceding table. You would incur these hypothetical expenses whether or not you were to redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years	5 Years	10 Years
$81	$252	$439	$978

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 157% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to generate returns by utilizing several alternative strategies that, individually and collectively, are expected to have low correlation with traditional capital markets and that collectively are expected to have lower volatility than the overall U.S. stock market. The strategies are based on the advisor's view regarding investable opportunities across capital markets. The Fund pursues strategies that include the following: long/short equity, event driven, fixed income relative value, currencies, commodity-linked investments, and equity index futures. The Fund will hold long and/or short positions within each strategy in an allocation that attempts to minimize market exposure, while attempting to capture attractive risk premiums identified by the advisor. The advisor expects that, over the long term, the assets underlying its long positions will outperform (appreciate more than or depreciate less than) the assets underlying its short positions.

The Fund implements these strategies by investing—either directly or indirectly through a wholly owned subsidiary—in a broad range of investments that may include, but are not limited to, the following: equities; fixed income instruments;

2

options; foreign currency exchange forward contracts; futures, including commodity, global equity index, and U.S. and foreign Treasury futures; and swaps.

The Fund seeks to generate absolute returns independent of market conditions, while managing volatility by combining strategies with different volatility patterns. The Fund is expected to utilize leverage in an attempt to match the expected risk profile of each individual strategy and the fund overall to a targeted level. A strategy will generate a positive return if stocks or other instruments held long (long positions) in the aggregate outperform stocks or other instruments sold short (short positions). This will happen if the long positions increase in value (appreciate) while the short positions decline in value (depreciate) or if the long positions appreciate more than, or depreciate less than, the short positions.

The Fund has adopted a risk methodology that targets a fixed range of volatility set by the advisor. This fixed range of volatility may change from time to time. The advisor will consider risk level of the individual strategies, composition of the portfolio, and market conditions when determining the fixed volatility range.

Although the Fund generally expects to maintain an approximate equal weighting among the strategies, the advisor may increase or decrease a strategy's weighting within the Fund to a level deemed appropriate to further the Fund's investment objective. In addition, the advisor may discontinue use of any of the strategies or add one or more new strategies if deemed to be in the best interests of the Fund.

The strategies employed by the Fund include:

•Long/Short Equity: The Fund may engage in strategies that seek to provide both long and short exposure to equity securities. This strategy involves simultaneously purchasing equities (e.g., U.S. and foreign stocks) the advisor expects to increase in value (i.e., investing long) and selling equities the advisor expects to decrease in value (i.e., short selling). This strategy may maintain overweightings in a variety of industry and sector exposures when seeking to capitalize on pricing inefficiencies between related equity securities. When taking a short position, the Fund sells a stock that it does not own and then borrows the stock from a third party to meet its settlement obligations. The Fund seeks to reduce the net exposure of the overall portfolio to general market movements and to minimize volatility by simultaneously engaging in long investing and short selling.

•Event Driven: The Fund may engage in event driven strategies, which seek to profit from investing in, and in some cases shorting, the securities (e.g., U.S. and foreign stocks) of a company based on the belief that a specific event or catalyst will affect the price of the company's stock. This strategy attempts to capitalize on price discrepancies and returns generated by an impending corporate activity, such as an acquisition or merger. The advisor may also engage in this strategy using futures, forwards, or swaps. Foreign currency exchange forward contracts may be used to

3

hedge currency risks presented by securities transactions. Swaps and futures may be used to create synthetic exposure to securities.

•Fixed Income Relative Value: The Fund may seek to profit by capitalizing on perceived mispricing of various liquid fixed income or interest rate-sensitive securities. This strategy will employ a variety of quantitative and qualitative methods to identify securities it believes are mispriced or display liquidity discrepancies based on historical, fundamental, or technical factors. The advisor may also engage in this strategy primarily using U.S. Treasury futures.

•Currencies: The Fund may utilize this strategy to benefit from expected currency movements across countries through the use of long and short foreign currency exchange forward contracts. The Fund seeks to benefit from premiums associated with selling currencies of countries with poor fundamental characteristics and purchasing currencies of countries with strong fundamental characteristics.

•Commodity-Linked Investments: The Fund may engage in investments that create both long and short exposure to commodities by using exchange-traded commodity futures contracts, commodity-linked swaps, or other commodity-linked investments. Commodities include real assets such as agricultural products, livestock, precious and industrial metals, and energy products. The Fund typically obtains exposure to commodities by investing a portion of its assets in a wholly owned subsidiary, which in turn invests in commodity-linked investments and fixed income securities. The Fund may also obtain exposure to commodities by investing directly in commodity-linked investments. Commodity-linked investments include commodity futures contracts, commodity-linked structured notes, commodity-linked swaps, exchange-traded commodity pools or funds, and other commodity-linked instruments.

•Equity Index Futures: The Fund may utilize long and short positions in global equity index futures to capture excess return opportunities. The Fund seeks to benefit from global differences in market and fundamental characteristics by buying equity index futures with strong characteristics and selling equity index futures with poor characteristics.

Principal Risks

An investment in the Fund could lose money over short, intermediate, or even long periods of time. Returns may vary substantially over time, and there is no guarantee that the Fund will achieve its investment objective or that any of its investment strategies individually or collectively will succeed.

The Fund's strategies involve the use of leverage, so its investment program may be considered speculative and is expected to involve considerable risks. The Fund could lose money at any time and may underperform the markets in which it invests during any given period, regardless of whether such markets rise or fall.

4

The Fund is subject to the risks described below. Each of these risks, alone or in combination with other risks, has the potential to hurt Fund performance, sometimes significantly.

Absolute Return Investing Risk

Absolute return investing is complex and may involve greater risk than investing in a traditional portfolio of stocks, bonds, and cash. There is no guarantee that the performance of the Fund will have low correlation with the returns of traditional capital markets. It is possible that the Fund's investment returns may converge with the investment returns of equity or fixed income markets during a period of declining stock prices, thereby eliminating the diversification benefit that the advisor expects from the strategies. During these times, the strategies' correlations could increase, which in turn could increase the Fund's overall volatility.

Manager Risk

The Fund is subject to manager risk, which is the chance that poor investment selections, poor asset allocation decisions, and/or poor strategy execution by the advisor will cause the Fund to fail to achieve its objective or to generate lower returns than would be achieved from different investment selections and/or asset allocation decisions. Poor investment selection by the advisor could also cause the Fund to underperform relevant benchmarks or other funds with similar investment objectives.

Derivatives Risk

The use of derivatives—such as futures contracts, foreign currency exchange forward contracts, swap agreements, options, and warrants—presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities. The use of derivatives can lead to losses because of adverse movements in the price or value of the underlying security, commodity, asset, index, or reference rate. Derivative strategies often involve leverage, which may increase a loss, potentially causing the Fund to lose more money than it would have lost had it invested in the underlying security. Also, a liquid market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. In addition, regulators and futures exchanges have established limits, referred to as position limits, on the maximum net long or net short positions that any person may hold or control, in particular derivatives contracts. Some contract positions, such as commodity futures contracts, held by the Fund and/or the subsidiary may have to be liquidated at disadvantageous times or prices to avoid exceeding such position limits, which may adversely affect the Fund's total return. The use of a derivative subjects the investor to the risk of nonperformance by the counterparty (i.e., counterparty risk), potentially resulting in delayed or partial payment or even nonpayment of amounts due under the derivative contract.

5

Short-Selling Risk

Short-selling risk is the chance that the Fund will lose money in connection with its short sales of securities or other instruments. Short selling allows an investor to profit from declines in the prices of securities or other instruments. There is no guarantee that the price of the securities or other instruments will decline; in fact, it may rise. To generate cash to close out a short position, the Fund may have to sell a related long position at a disadvantageous time. The Fund's loss on a short sale is potentially unlimited, because there is no limit on the price a security or instrument sold short could attain.

Commodity-Linked Investment Risk

The Fund has the ability to obtain commodity exposure by investing directly in commodity-linked investments or investing indirectly in those investments through a wholly owned subsidiary organized under the laws of the Cayman Islands. These investments subject the Fund to risks associated with investments in commodities. Commodity futures trading is volatile and even a small movement in market prices could cause large losses. Commodity-linked investment risks include commodity futures trading risk, counterparty risk, derivatives risk, and tax risk. These risks are described under More on the Fund. Investment in a wholly owned subsidiary also subjects the Fund to subsidiary investment risk, manager risk, and tax risk. These subsidiary-related risks are also described in more detail under More on the Fund. In particular, the subsidiary will not be organized as a mutual fund that is registered under any U.S. federal or state securities laws, including the Investment Company Act of 1940. The tax treatment of the Fund's investment in the subsidiary may be adversely affected by changes in laws or regulations, or interpretations of existing laws or regulations, of the United States and/or the jurisdiction of the subsidiary.

Leverage Risk

Leverage risk is the chance that any leveraged losses will exceed the principal amount invested by the Fund. Returns from a leveraged investment have the potential to be more volatile than returns from traditional stock and bond investments, which exposes the Fund to heightened risks.

Stock Market Risk

The Fund is subject to stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. The Fund's investments in foreign stocks can be riskier than U.S. stock investments. Foreign stocks may be more volatile and less liquid than U.S. stocks. The prices of foreign stocks and the prices of U.S. stocks may move in opposite directions.

Currency Risk

The Fund is subject to currency risk, which is the chance that the Fund could suffer losses from currency-related investments. For example, if positions the Fund holds

6

long decline in value and/or positions the Fund holds short increase in value, then the Fund could incur a loss. Currency prices can be highly volatile and trading currencies for non-hedging purposes is generally considered speculative and involves a high risk of a substantial loss of invested capital.

Nondiversification Risk

The Fund is also subject to nondiversification risk, which is the chance that the Fund's performance may be hurt disproportionately by the poor performance of relatively few investments. The Fund is considered nondiversified, which means that it may invest a greater percentage of its assets in the securities of particular issuers as compared with diversified mutual funds.

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Annual Total Returns

The following bar chart and table are intended to help you understand the risks of investing in the Fund. The bar chart shows how the performance of the Fund has varied from one calendar year to another over the periods shown. The table shows how the average annual total returns of the Fund compare with those of a relevant market index, which has investment characteristics similar to those of the Fund. Effective November 1, 2019, the FTSE 3-month US T-Bill Index +4% was replaced with the FTSE 3-month Treasury Bill Index in order to align with the Fund's investment objective and risk methodology. The Spliced Alternative Strategies Index reflects the performance of the FTSE 3-month US T-Bill Index +4% through October 31, 2019, and the FTSE 3-month Treasury Bill Index thereafter.

More on the Fund

This prospectus describes the principal risks you would face as a Fund shareholder. It is important to keep in mind one of the main principles of investing: generally, the higher the risk of losing money, the higher the potential reward. The reverse, also, is generally true: the lower the risk, the lower the potential reward. As you consider an investment in any mutual fund, you should take into account your personal tolerance

for fluctuations in the securities markets. Look for this symbol throughout the prospectus. It is used to mark detailed information about the more significant risks that you would confront as a Fund shareholder. To highlight terms and concepts important to mutual fund investors, we have provided Plain Talk® explanations along the way. Reading the prospectus will help you decide whether the Fund is the right investment for you. We suggest that you keep this prospectus for future reference.

The following sections explain the principal investment strategies and policies that the Fund uses in pursuit of its objective. The Fund's board of trustees, which oversees the Fund's management, may change investment strategies or policies in the interest of shareholders without a shareholder vote, unless those strategies or policies are designated as fundamental. Note that the Fund's investment objective is not fundamental and may be changed without a shareholder vote.

Plain Talk About Absolute Return Investing

Conventional approaches to investing money seek to either track or exceed the performance of a particular asset or sub-asset class. An absolute return approach to investing, however, seeks capital appreciation over the long term while exhibiting low correlation with the returns of traditional capital markets. During periods of falling or rising stock prices, an absolute return investment may generate returns that are markedly different from the returns of the stock market, for better or worse. Some absolute return strategies are designed to take advantage of disparities or inefficiencies in different markets or to benefit from cyclical relationships or special situations. Certain absolute return strategies may be designed to systematically capture risk premiums across the financial markets by offering risk transfer opportunities to market participants. Other absolute return strategies can be designed to capture mispricings across asset classes that have historically positive long-term returns while exhibiting low correlation with stock market returns. Generally speaking, an absolute return approach to investing places a premium on manager insight, effective execution, and disciplined risk controls. Absolute return strategies can use a high degree of implicit or explicit leverage, which introduces the potential for a substantial loss of invested capital over short periods of time.

10

Absolute return investing is complex and may involve greater risk than investing in a traditional portfolio of stocks, bonds, and cash. There is no guarantee that the performance of the Fund will have low correlation with the returns of traditional capital markets. It is possible that the Fund's investment returns may converge with the investment returns of equity or fixed income markets during a period of declining stock prices, thereby eliminating the diversification benefit that the advisor expects from the strategies. During these times, the strategies' correlations could increase, which in turn could increase the Fund's overall volatility.

Plain Talk About Costs of Investing

Costs are an important consideration in choosing a mutual fund. That is because you, as a shareholder, pay a proportionate share of the costs of operating a fund and any transaction costs incurred when the fund buys or sells securities. These costs can erode a substantial portion of the gross income or the capital appreciation a fund achieves. Even seemingly small differences in expenses can, over time, have a dramatic effect on a fund's performance.

An investment in the Fund could lose money over short, intermediate, or even long periods of time. Returns may vary substantially over time, and there is no guarantee that the Fund will achieve its investment objective or that any of its investment strategies individually or collectively will succeed.

Portfolio Construction

The Fund seeks to provide shareholders with an absolute return through investments in various alternative strategies. The Fund is constructed to provide returns that have low correlation to traditional capital markets. Therefore, the Fund's strategies have been designed and selected to have minimal long-term correlation with each other. The Fund will seek to be broadly diversified across a range of markets. Each of the strategies is constructed using a bottom up systematic process.

The advisor constructs each strategy individually then combines them into a single portfolio using a long-term strategic risk-weighting process. In general, the advisor's portfolio construction process focuses on adding value through diversified risk weighting over the long-term.

Although the Fund's returns are designed to have low long-term correlation with traditional capital market returns on average over time, the Fund may experience periods of increased correlation and risk relative to capital markets. Although the Fund may simultaneously use one type of exposure in more than one strategy, the exposure will be independently selected to achieve the goal of the particular strategy. The advisor will attempt to mitigate risk through the allocation of assets among the

11

strategies and through active monitoring of volatility, counterparties, and other risk measures.

Security Selection

Vanguard manages each strategy through the use of a continually evolving process that was developed and is managed by Vanguard's Quantitative Equity Group. All potential enhancements to the process go through rigorous peer vetting and validation before being implemented. The advisor utilizes the resulting process to determine which securities and other instruments to buy long and sell short for the portfolio. The Fund's investments may include, but are not limited to, the following: equities; fixed income instruments; options; foreign currency exchange forward contracts; futures, including commodity, global equity index, and U.S. and foreign Treasury futures; and swaps. The Fund gains exposure to these instruments either directly by investing in the instruments or indirectly by investing in a subsidiary that invests in the instruments.

The Fund may invest in selected other investments that the advisor believes have attractive expected risk/return characteristics and that are compatible with the existing strategies of the Fund.

The Fund is subject to manager risk, which is the chance that poor investment selections, poor asset allocation decisions, and/or poor strategy execution by the advisor will cause the Fund to fail to achieve its objective or to generate lower returns than would be achieved from different investment selections and/or asset allocation decisions. Poor investment selection by the advisor could also cause the Fund to underperform relevant benchmarks or other funds with similar investment objectives.

The performance of the Fund depends on the net returns of its long and short positions, and it is possible for the Fund to experience a net loss across all positions. If the Fund's investment program is successful, however, the net returns of its long and short positions will produce long-term capital appreciation that reflects the quality of the advisor's security selections, with less volatility than the U.S. stock market.

The Fund is subject to nondiversification risk, which is the chance that the Fund's performance may be hurt disproportionately by the poor performance of relatively few investments. The Fund is considered nondiversified, which means that it may invest a greater percentage of its assets in the securities of particular issuers as compared with diversified mutual funds.

Plain Talk About Alternative Strategies Funds

What is an alternative strategies mutual fund? While there is no clear definition of "alternative" in the mutual fund space, an alternative strategies mutual fund is generally understood to be a fund whose principal investment strategy falls into one or more of the three following buckets: (1) non-traditional asset classes (such as currencies), (2) non-traditional strategies (such as long/short equity positions), and/or (3) illiquid assets (such as private debt). These investment strategies generally seek to produce positive risk-adjusted returns (or alphas) that are not closely correlated to traditional investments or benchmarks. These investment strategies differ from those of traditional mutual funds that pursue long-only strategies in asset classes. It is possible for an alternative strategies mutual fund to experience considerable losses.

Market Exposure

• U.S. and Foreign Stocks

The Fund invests, to varying degrees, in large-, mid-, and small-capitalization stocks of companies in the United States, as well as in stocks of companies located in markets around the world. The Fund may hedge some of its currency exposure to foreign stocks in order to reduce volatility caused by changes in currency exchange rates.

The Fund is subject to stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. Investments in foreign stocks can be riskier than U.S. stock investments. Foreign stocks may be more volatile and less liquid than U.S. stocks. The prices of foreign stocks and the prices of U.S. stocks may move in opposite directions.

The Fund is subject to country/regional risk and currency risk. Country/regional risk is the chance that world events—such as political upheaval, financial troubles, or natural disasters—will adversely affect the value of securities issued by companies in foreign countries or regions. Currency risk is the chance that the value of a foreign investment, including a derivative that provides exposure to a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates.

The advisor expects that much of the risks of investing in stocks will be offset through strategy construction, for example, taking short positions in stocks. That said, there is no guarantee that strategy construction will always be successful in reducing stock market risk.

13

•Bonds

The Fund may invest in instruments that provide exposure to fixed income markets, including U.S. Treasury futures, and to varying degrees, a wide spectrum of short-, intermediate-, and long-term U.S. government, U.S. agency, and investment-grade U.S. corporate bonds; mortgage-backed and asset-backed securities; and government, agency, corporate, and securitized investment-grade foreign bonds issued in currencies other than the U.S. dollar. The Fund may hedge some of its currency exposure in order to reduce volatility caused by changes in currency rates. Fixed income investments may be used in furtherance of an investment strategy and also to enable the Fund to satisfy margin deposit, collateralization, and/or segregation obligations associated with its use of derivatives.

The Fund is subject to interest rate risk, which is the chance that prices of fixed income instruments, including, but not limited to, bonds and U.S. Treasury futures, will be affected by changes in interest rates. Increasing interest rates could cause positions of the long portfolio to decline in value, while decreasing interest rates could cause positions of the short portfolio to decline in value.

Plain Talk About Bonds and Interest Rates

As a rule, when interest rates rise, bond prices fall. The opposite is also true: Bond prices go up when interest rates fall. Why do bond prices and interest rates move in opposite directions? Let's assume that you hold a bond offering a 4% yield. A year later, interest rates are on the rise and bonds of comparable quality and maturity are offered with a 5% yield. With higher-yielding bonds available, you would have trouble selling your 4% bond for the price you paid—you would probably have to lower your asking price. On the other hand, if interest rates were falling and 3% bonds were being offered, you should be able to sell your 4% bond for more than you paid.

How mortgage-backed securities are different: In general, declining interest rates will not lift the prices of mortgage-backed securities—such as those guaranteed by the Government National Mortgage Association—as much as the prices of comparable bonds. Why? Because when interest rates fall, the bond market tends to discount the prices of mortgage-backed securities for prepayment risk— the possibility that homeowners will refinance their mortgages at lower rates and cause the bonds to be paid off prior to maturity. In part to compensate for this prepayment possibility, mortgage-backed securities tend to offer higher yields than other bonds of comparable credit quality and maturity. In contrast, when interest rates rise, prepayments tend to slow down, subjecting mortgage-backed securities to extension risk—the possibility that homeowners will repay their mortgages at slower rates. This will lengthen the duration or average life of mortgage-backed securities held by a fund and delay the fund's ability to reinvest proceeds at higher interest rates, making the fund more sensitive to changes in interest rates.

The Fund is subject to credit risk, which is the chance that the issuer of a security will fail to pay interest or principal in a timely manner or that negative perceptions of the issuer's ability to make such payments will cause the price of that security to decline, thus reducing the Fund's return.

The Fund is subject to income risk, which is the chance that the Fund's income will decline because of falling interest rates. A fund holding bonds will experience a decline in income when interest rates fall because the fund then must invest new cash flow and cash from maturing bonds in lower-yielding bonds. Income risk is generally higher for funds holding short-term bonds and lower for funds holding long-term bonds.

15

The Fund is subject to call risk, which is the chance that during periods of falling interest rates, issuers of callable bonds may call (redeem) securities with higher coupon rates or interest rates before their maturity dates. If the Fund holds a bond that is called, the Fund would then lose any price appreciation above the bond's call price and would be forced to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund's income. For mortgage-backed securities, this risk is known as prepayment risk.

The Fund is subject to country/regional risk, which is the chance that world events—such as political upheaval, financial troubles, or natural disasters— will adversely affect the value and/or liquidity of securities issued by foreign governments, government agencies, or companies.

The Fund is subject, to a limited extent, to event risk, which is the chance that corporate fixed income securities will suffer a substantial decline in credit quality and market value because of a corporate restructuring.

Plain Talk About Bond Maturities

A bond is issued with a specific maturity date—the date when the issuer must pay back the bond's principal (face value). Bond maturities range from less than 1 year to more than 30 years. Typically, the longer a bond's maturity, the more price risk you, as a bond investor, will face as interest rates rise—but also the higher the potential yield you could receive. Longer-term bonds are more suitable for investors willing to take a greater risk of price fluctuations to get higher and more stable interest income. Shorter-term bond investors should be willing to accept lower yields and greater income variability in return for less fluctuation in the value of their investment. The stated maturity of a bond may differ from the effective maturity of a bond, which takes into consideration that an action such as a call or refunding may cause bonds to be repaid before their stated maturity dates.

Commodity-Linked Investment Risk

The Fund may allocate a portion of its assets to investments that create long or short exposure to commodities (e.g., commodity futures). Commodities include real assets such as agricultural products, livestock, precious and industrial metals, and energy products. Commodity futures prices have a historically low correlation with the returns of the stock and bond markets.

The Fund intends to obtain exposure to commodities primarily through investing a portion of its assets in a wholly owned subsidiary organized under the laws of the Cayman Islands, which in turn invests in commodity-linked investments and fixed

16

income securities. The Fund's ownership of the subsidiary exposes it to the same risks as if it were invested directly in the assets owned by the subsidiary. The Fund may also invest directly in certain types of commodity-linked investments. The Fund's direct and indirect commodity-linked investments may include commodity futures contracts, commodity-linked swaps, exchange-traded commodity pools or funds, and other commodity-linked instruments. The subsidiary's fixed income investments include, but are not limited to, cash instruments, money market instruments, and short- term bonds. Fixed income investments provide liquidity for the subsidiary and may serve as margin or collateral for the subsidiary's commodity-linked investments.

Subsidiary investment risk includes the risk that because a subsidiary is not registered under any U.S. federal or state securities laws, it does not offer the same investor protections available to shareholders of registered investment companies.

The subsidiary, which is managed by Vanguard, will not be organized as a mutual fund that is registered under any U.S. federal or state securities laws, including the Investment Company Act of 1940 (1940 Act), and is therefore not subject to all the investor protections of the 1940 Act.

There is no assurance that the Fund will be permitted to continue to invest indirectly in commodity-linked investments through the subsidiary. Changes in the laws or regulations, or interpretations of existing laws or regulations, of the United States and/or the jurisdiction of the subsidiary could limit the Fund's ability to invest in the subsidiary, impact the way in which the subsidiary operates, increase the subsidiary's expenses, or otherwise adversely affect the Fund and/or the subsidiary. Moreover, the changes may be retroactive. For example, the subsidiary intends to operate in a manner that the Fund's qualifying income requirement is met under current U.S. tax law. However, there is no assurance that future changes in this law, or interpretations of this law, will not adversely affect the Fund. Also, although the subsidiary is not expected to owe income or other taxes in its jurisdiction of organization, if that jurisdiction's tax laws were changed and the subsidiary was required to pay taxes, the Fund's investment returns may decrease. Because Vanguard receives asset-based fees from the subsidiary for services provided to the subsidiary, Fund assets invested in the subsidiary are excluded when allocating to the Fund its share of the costs of Vanguard operations.

Tax risk is the chance that the Fund's commodity-linked investments could adversely affect the Fund's regulated investment company status.

The Fund's ability to make direct and indirect investments in some of the commodity- related investments previously described, including in the wholly owned subsidiary, is limited by the Fund's intention to qualify as a regulated investment company (RIC) under the Internal Revenue Code of 1986, as amended (the IRC), including the requirement that 90% of the Fund's gross income for each taxable year constitute

17

"qualifying income." As an RIC, the Fund also may not invest more than 25% of its assets in the subsidiary.

The Fund generally intends to gain direct or indirect exposure to the commodity markets through investments that generate qualifying income by investing directly in commodity-linked investments the Fund believes give rise to qualifying income or by investing indirectly in commodity-linked investments through the subsidiary. In addition, the subsidiary will be operated in a manner that is intended to enable the Fund to comply with the IRC requirements applicable to RICs. However, if the Fund does not appropriately limit its investments in the subsidiary or in commodity-related investments, or if the investments (or the income earned on the investments) are recharacterized for U.S. tax purposes, the Fund's status as an RIC may be jeopardized. Moreover, any recharacterization of these investments (or the income earned on the investments) may be retroactive. If the Fund were to fail to qualify as an RIC in any taxable year, the Fund would be subject to Fund-level taxation, reducing the amount of income available for distribution to shareholders and reducing the net asset value of its shares.

Manager risk is the chance that poor strategy execution will cause the subsidiary to fail to achieve its investment objective.

The subsidiary's success will depend on the advisor's ability to successfully invest in commodity-linked investments such as commodity futures and commodity-linked swaps and to invest the subsidiary's assets in a combination of fixed income investments. The subsidiary is subject to the risk that it will not be successful in executing this strategy, and there is no guarantee that the subsidiary will achieve its investment objective. The subsidiary could lose money at any time.

Plain Talk About Commodities

Commodities are raw materials used to create the goods that consumers buy. They include a wide range of physical assets, such as agricultural products, livestock, precious metals, energy products, and industrial metals. Commodities can be purchased for immediate delivery ("on the spot") or delivery within a specific time period in the future under the terms of a futures contract. An exchange-traded commodity futures contract provides for the purchase and sale of a specified type and quantity of a commodity during a stated delivery month. A futures contract on an index of commodities provides for the payment and receipt of cash based on the level of the index at settlement or liquidation of the contract. Unlike equity securities, futures contracts, by their terms, have stated expirations, and at a specified time prior to expiration, trading in a futures contract for the current delivery month will cease. As a result, an investor wishing to maintain exposure to a futures contract on a particular commodity with the nearest expiration must close out a position in the expiring contract and establish a new position in the contract for the next delivery month. This process is referred to as "rolling." An investor will profit from rolling a futures contract if the cost for the new contract is lower than the cost of the expiring contract. Conversely, an investor will lose money by rolling a futures contract if the cost for the new contract is higher than the cost of the expiring contract.

Commodity futures trading risk is the chance that the Fund could lose all, or substantially all, of its investments in instruments linked to the returns of commodity futures. Commodity futures trading is volatile, and even a small movement in market prices could cause large losses.

The prices of commodity futures are subject to change based on various factors, including, but not limited to, the following: lack of liquidity; global supply and demand for commodities; disorderly markets; limitations on deliverable supplies; participation of hedgers and speculators; domestic and foreign interest rates and investors' expectations concerning interest rates; domestic and foreign inflation rates and investors' expectations concerning inflation rates; investment and trading activities of institutional investors; global or regional political, economic, or financial events and situations; government regulation and intervention; technical and operational or system failures; nuclear accident; terrorism; and natural disasters.

Derivatives Risk

The Fund may invest in derivatives only if the expected risks and rewards of the derivatives are consistent with the investment objective, policies, strategies, and risks of the Fund as disclosed in this prospectus.

19

Derivatives risk is the risk associated with the use of futures contracts, options on futures contracts, options on securities, swap agreements, warrants, forward contracts, and other derivatives. Investments in derivatives may involve risks different from, and possibly greater than, those of investments directly in the underlying securities or assets.

Losses involving certain derivatives can sometimes be substantial or even greater than the principal amount invested—in part because a relatively small price movement may result in an immediate and substantial loss to the investor. Derivatives also involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative may not correlate perfectly with the underlying securities or assets. The market for many derivatives is, or can suddenly become, illiquid, which may result in significant, rapid, and unpredictable changes in the prices for derivatives.

The use of certain derivatives subjects the investor to counterparty risk, which is the risk of nonperformance by the counterparty, potentially resulting in delayed or partial payment or even nonpayment of amounts due under the derivative contract. There are typically contractual remedies that may be pursued under a derivatives agreement in the event of default by a counterparty. The Fund and the subsidiary each expects to hold margin or collateral to secure the obligations of a counterparty in an effort to mitigate this risk.

Plain Talk About Derivatives

Generally speaking, a derivative is a financial contract whose value is based on the value of a financial asset (such as a stock, a bond, or a currency), a physical asset (such as gold, oil, or wheat), a market index, or a reference rate. Some forms of derivatives—such as exchange-traded futures and options on securities, commodities, or indexes—have been trading on regulated exchanges for decades. These types of derivatives are standardized contracts that can easily be bought and sold and whose market values are determined and published daily. On the other hand, non-exchange-traded derivatives—such as certain swap agreements and foreign currency exchange forward contracts—tend to be more specialized or complex and may be less liquid and more difficult to accurately value.

Liquidity risk is the chance that the markets, assets, and instruments in which the Fund invests are, or may become, illiquid.

The advisor expects that the Fund generally will seek to invest in liquid markets, assets, and instruments, although the Fund may have the ability to invest a portion of its assets in markets, assets, or instruments that are or may become illiquid. There is

20

no assurance that investments that were liquid when purchased will not suddenly become illiquid for an indefinite period of time.

Short-Selling Risk

The Fund's use of short sales in combination with its long positions may not be successful and may result in greater losses or lower returns than if the Fund held only long positions. For example, it is possible that the instruments the Fund holds long will underperform (appreciate less than or depreciate more than) the instruments it holds short, resulting in losses to the Fund. Any gain from a short position may be partially or totally offset by a decline in a long position, or vice versa.

Plain Talk About Equity Short Sales

A short sale of an equity security is the sale of a security that the seller does not own. In order to deliver the security to the purchaser, the short seller borrows the security, typically from a broker-dealer or an institutional investor, for a fee. The short seller later closes out the position by returning the security to the lender, typically by purchasing the same security on the open market. A short sale theoretically carries the risk of an unlimited loss, because the price of the underlying security could increase without limit, thus increasing the cost of buying that security to cover the short position. In addition, there can be no assurance that the security needed to cover a short position will be available for purchase. Also, the purchase of a security to close out the short position can itself cause the price of the security to rise further, thereby exacerbating the loss. Short selling is often used to profit from an expected downward price movement in a security.

Short-selling risk is the chance that the Fund will lose money in connection with its short sales of securities or other instruments.

Short selling allows an investor to profit from declines in the prices of securities or other instruments the investor does not own. To engage in an equity short sale, the Fund sells a security that it does not own and borrows, for a fee, securities to meet its settlement obligation. There is no guarantee that the price of the borrowed securities will decline; in fact, it may rise. Short selling of equity securities involves higher transaction costs than long-only investing. For example, to generate cash to close out a short position, the Fund may have to sell a related long position at disadvantageous times to produce cash to unwind a short position. The Fund's loss on a short sale is potentially unlimited, because there is no limit on the price appreciation a borrowed security or instrument sold short could attain.

21

 

Plain Talk About Short Sale Borrowing and Dividend Expenses

The Fund engages in short selling as a principal investment strategy. A short sale occurs when the Fund sells a stock it does not own and then borrows the stock from a lender in order to settle the transaction. When the Fund sells short, it will normally incur two types of expenses—borrowing expenses and dividend expenses—which increase the Fund's expense ratio.

In connection with the short sale, the Fund may receive income or be charged a fee on borrowed stock. This income or fee is calculated on a daily basis, based upon the market value of the borrowed stock and a variable rate that is dependent upon the availability of the stock. The net amounts of income or fees are recorded as "interest income" (for net income received) or "borrowing expense on securities sold short" (for net fees charged) on the Fund's Statement of Operations.

The Fund incurs dividend expenses until the borrowed stock is returned to the lender. These expenses are paid to the lender of the stock and are based upon the amount of any dividends declared on the stock. Having sold the borrowed stock, the Fund does not itself collect the dividends, and thus has a net expense payable to the lender. This payment is recorded as "dividend expense on securities sold short" on the Fund's financial statements. Short sale dividend expenses generally reduce the market value of the stock by the amount of the dividend declared, thus increasing the Fund's unrealized gain or reducing the Fund's unrealized loss on the stock sold short.

Leverage Risk

Leverage risk is the chance that any leveraged losses will exceed the principal amount invested by the Fund. Returns from a leveraged investment have the potential to be more volatile than returns from traditional stock and bond investments, which exposes the Fund to heightened risks.

Leverage exists when an investor has the right to a return on a total investment amount that exceeds the cash amount the investor contributed to the investment. Leverage magnifies the effect of gains and losses. The Fund's losses from its leveraged investments could be considerable.

Leverage-financing risk is the chance that the Fund will be unable to access and maintain financing sufficient to leverage its investments to targeted levels.

The Fund will require the use of leverage in order for its strategies to reach targeted volatility levels. It is possible that the prime broker or other counterparties that finance

22

the leverage employed by the Fund may not be able or willing to provide the level of financing that the advisor believes is required to achieve its volatility targets.

Currency Risk

Currency risk is the chance that the Fund could suffer losses from currency- related investments. For example, if positions the Fund holds long decline in value and/or positions the Fund holds short increase in value, then the Fund could incur a loss. Currency prices can be highly volatile and trading currencies for non-hedging purposes is generally considered speculative and involves a high risk of a substantial loss of invested capital.

Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including, but not limited to, changes in interest rates, impositions of currency controls, devaluation of a currency by a country's government or banking authority, or political developments in the United States or abroad.

Other Investment Policies and Risks

Although the Fund actively allocates its assets principally among some combination of equities; fixed income instruments; options; foreign currency exchange forward contracts; futures, including commodity, global equity index, and U.S. and foreign Treasury futures; and swaps, the Fund may make other kinds of investments to achieve its objective.

The Fund may invest up to 15% of its net assets in illiquid securities. Illiquid securities are investments that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. Restricted securities are a special type of illiquid security; these securities have not been publicly issued and legally can be resold only to qualified buyers. From time to time, the board of trustees may determine that particular restricted securities are not illiquid, and those securities may then be purchased by the Fund without limit.

The Fund may invest a portion of its assets in shares of stock or bond exchange-traded funds (ETFs). ETFs provide returns similar to those of stocks or bonds. The Fund may purchase ETFs when doing so will reduce the Fund's transaction costs, facilitate cash management, mitigate risk, or have the potential to add value because the instruments are favorably priced. Vanguard receives no additional revenue from Fund assets invested in ETF Shares of other Vanguard funds. Fund assets invested in ETF Shares are excluded when allocating to the Fund its share of the costs of Vanguard operations.

23

Cash Management

The Fund's daily cash balance may be invested in Vanguard Market Liquidity Fund and/or Vanguard Municipal Cash Management Fund (each, a CMT Fund), which are low-cost money market funds. When investing in a CMT Fund, the Fund bears its proportionate share of the expenses of the CMT Fund in which it invests. Vanguard receives no additional revenue from Fund assets invested in a CMT Fund.

Methods Used to Meet Redemption Requests

Under normal circumstances, the Fund typically expects to meet redemptions with positive cash flows. When this is not an option, the Fund seeks to maintain its risk exposure by selling a cross section of the Fund's holdings to meet redemptions, while also factoring in transaction costs. Additionally, the Fund may work with larger clients to implement their redemptions in a manner that is least disruptive to the portfolio; see "Potentially disruptive redemptions" under Redeeming Shares in the Investing With Vanguard section.

Under certain circumstances, including under stressed market conditions, there are additional tools that the Fund may use in order to meet redemptions, including advancing the settlement of market trades with counterparties to match investor redemption payments or delaying settlement of an investor's transaction to match trade settlement within regulatory requirements. The Fund may also suspend payment of redemption proceeds for up to seven days; see "Emergency circumstances" under Redeeming Shares in the Investing With Vanguard section. Additionally under these unusual circumstances, the Fund may borrow money (subject to certain regulatory conditions and if available under board-approved procedures) through an interfund lending facility or through a bank line-of-credit, including a joint committed credit facility, in order to meet redemption requests.

Temporary Investment Measures

The Fund may temporarily depart from its normal investment policies and strategies when the advisor believes that doing so is in the Fund's best interest, so long as the strategy or policy employed is consistent with the Fund's investment objective. For instance, the Fund may invest beyond its normal limits in derivatives or exchange- traded funds that are consistent with the Fund's investment objective when those instruments are more favorably priced or provide needed liquidity, as might be the case if the Fund is transitioning assets from one advisor to another or receives large cash flows that it cannot prudently invest immediately.

In addition, the Fund may take temporary defensive positions that are inconsistent with its normal investment policies and strategies—for instance, by allocating substantial assets to cash equivalent investments or other less volatile instruments— in response to adverse or unusual market, economic, political, or other conditions. In

24

doing so, the Fund may succeed in avoiding losses but may otherwise fail to achieve its investment objective.

Frequent Trading or Market-Timing

Background. Some investors try to profit from strategies involving frequent trading of mutual fund shares, such as market-timing. For funds holding foreign securities, investors may try to take advantage of an anticipated difference between the price of the fund's shares and price movements in overseas markets, a practice also known as time-zone arbitrage. Investors also may try to engage in frequent trading of funds holding investments such as small-cap stocks and high-yield bonds. As money is shifted into and out of a fund by a shareholder engaging in frequent trading, the fund incurs costs for buying and selling securities, resulting in increased brokerage and administrative costs. These costs are borne by all fund shareholders, including the long-term investors who do not generate the costs. In addition, frequent trading may interfere with an advisor's ability to efficiently manage the fund.

Policies to address frequent trading. The Vanguard funds (other than money market funds and short-term bond funds, but including Vanguard Short-Term Inflation- Protected Securities Index Fund) do not knowingly accommodate frequent trading. The board of trustees of each Vanguard fund (other than money market funds and short- term bond funds, but including Vanguard Short-Term Inflation-Protected Securities Index Fund) has adopted policies and procedures reasonably designed to detect and discourage frequent trading and, in some cases, to compensate the fund for the costs associated with it. These policies and procedures do not apply to ETF Shares because frequent trading in ETF Shares generally does not disrupt portfolio management or otherwise harm fund shareholders. Although there is no assurance that Vanguard will be able to detect or prevent frequent trading or market-timing in all circumstances, the following policies have been adopted to address these issues:

•Each Vanguard fund reserves the right to reject any purchase request—including exchanges from other Vanguard funds—without notice and regardless of size. For example, a purchase request could be rejected because the investor has a history of frequent trading or if Vanguard determines that such purchase may negatively affect a fund's operation or performance.

•Each Vanguard fund (other than money market funds and short-term bond funds, but including Vanguard Short-Term Inflation-Protected Securities Index Fund) generally prohibits, except as otherwise noted in the Investing With Vanguard section, an investor's purchases or exchanges into a fund account for 30 calendar days after the investor has redeemed or exchanged out of that fund account.

•Certain Vanguard funds charge shareholders purchase and/or redemption fees on transactions.

25

See the Investing With Vanguard section of this prospectus for further details on Vanguard's transaction policies.

Each Vanguard fund (other than retail and government money market funds), in determining its net asset value, will use fair-value pricing when appropriate, as described in the Share Price section. Fair-value pricing may reduce or eliminate the profitability of certain frequent-trading strategies.

Do not invest with Vanguard if you are a market-timer.

Turnover Rate

Although the Fund generally seeks to invest for the long term, it may sell securities regardless of how long they have been held. The Financial Highlights section of this prospectus shows historical turnover rates for the Fund. A turnover rate of 100%, for example, would mean that the Fund had sold and replaced securities valued at 100% of its net assets within a one-year period. In general, the greater the turnover rate, the greater the impact transaction costs will have on a fund's return. Also, funds with high turnover rates may be more likely to generate capital gains, including short-term capital gains, that must be distributed to shareholders and will be taxable to shareholders investing through a taxable account.

The Fund and Vanguard

The Fund is a member of The Vanguard Group, a family of over 200 funds. All of the funds that are members of The Vanguard Group (other than funds of funds) share in the expenses associated with administrative services and business operations, such as personnel, office space, and equipment.

Vanguard Marketing Corporation provides marketing services to the funds. Although fund shareholders do not pay sales commissions or 12b-1 distribution fees, each fund (other than a fund of funds) or each share class of a fund (in the case of a fund with multiple share classes) pays its allocated share of the Vanguard funds' marketing costs.

Plain Talk About Vanguard's Unique Corporate Structure

The Vanguard Group is owned jointly by the funds it oversees and thus indirectly by the shareholders in those funds. Most other mutual funds are operated by management companies that are owned by third parties—either public or private stockholders—and not by the funds they serve.

26

Investment Advisor

The Vanguard Group, Inc. (Vanguard), P.O. Box 2600, Valley Forge, PA 19482, which began operations in 1975, serves as advisor to the Fund through its Quantitative Equity Group. As of October 31, 2019, Vanguard served as advisor for approximately $4.7 trillion in assets. Vanguard provides investment advisory services to the Fund pursuant to the Funds' Service Agreement and subject to the supervision and oversight of the trustees and officers of the Fund.

For the fiscal year ended October 31, 2019, the advisory expenses represented an effective annual rate of 0.09% of the Fund's average net assets.

Under the terms of an SEC exemption, the Fund's board of trustees may, without prior approval from shareholders, change the terms of an advisory agreement with a third- party investment advisor or hire a new third-party investment advisor—either as a replacement for an existing advisor or as an additional advisor. Any significant change in the Fund's advisory arrangements will be communicated to shareholders in writing. As the Fund's sponsor and overall manager, Vanguard may provide investment advisory services to the Fund at any time. Vanguard may also recommend to the board of trustees that an advisor be hired, terminated, or replaced or that the terms of an existing advisory agreement be revised. The Fund has filed an application seeking a similar SEC exemption with respect to investment advisors that are wholly owned subsidiaries of Vanguard. If the exemption is granted, the Fund may rely on the new SEC relief.

For a discussion of why the board of trustees approved the Fund's investment advisory arrangement, see the most recent semiannual report to shareholders covering the fiscal period ended April 30.

The managers primarily responsible for the day-to-day management of the Fund are:

Anatoly Shtekhman, CFA, Portfolio Manager at Vanguard. He has been with Vanguard since 2007 and has managed investment portfolios and co-managed the Fund since 2016. Education: B.S., University of Scranton; M.S., Boston College; M.B.A., The Wharton School of the University of Pennsylvania.

Fei Xu, CFA, Portfolio Manager at Vanguard. He has been with Vanguard since 2004 and has managed investment portfolios and co-managed the Fund since 2017. Education: B.S., Peking University; M.S., University of California, Los Angeles; M.B.A., Duke University.

The Fund's Statement of Additional Information provides information about each portfolio manager's compensation, other accounts under management, and ownership of shares of the Fund.

27

Dividends, Capital Gains, and Taxes

Fund Distributions

The Fund distributes to shareholders virtually all of its net income (interest and dividends, less expenses) as well as any net short-term or long-term capital gains realized from the sale of its holdings. Income and capital gains distributions, if any, generally occur annually in December. In addition, the Fund may occasionally make a supplemental distribution at some other time during the year.

You can receive distributions of income or capital gains in cash, or you can have them automatically reinvested in more shares of the Fund. However, if you are investing through an employer-sponsored retirement or savings plan, your distributions will be automatically reinvested in additional Fund shares.

Plain Talk About Distributions

As a shareholder, you are entitled to your portion of a fund's income from interest, dividends, and other sources as well as capital gains from the fund's sale of investments. Income consists of, among other things, the dividends that the fund earns from any stock holdings and the interest it receives from any bond investments. In general, capital gains are realized whenever the fund sells investments for higher prices than it paid for them. These capital gains are either short-term or long-term, depending on whether the fund held the investments for one year or less or for more than one year.

Basic Tax Points

Investors in taxable accounts should be aware of the following basic federal income tax points:

•Distributions are taxable to you whether or not you reinvest these amounts in additional Fund shares.

•Distributions declared in December—if paid to you by the end of January—are taxable as if received in December.

•Any dividend distribution or short-term capital gains distribution that you receive is taxable to you as ordinary income. If you are an individual and meet certain holding- period requirements with respect to your Fund shares, you may be eligible for reduced tax rates on "qualified dividend income,"if any, distributed by the Fund.

•Any distribution of net long-term capital gains is taxable to you as long-term capital gains, no matter how long you have owned shares in the Fund.

•Capital gains distributions may vary considerably from year to year as a result of the Fund's normal investment activities and cash flows.

28

•A sale or exchange of Fund shares is a taxable event. This means that you may have a capital gain to report as income, or a capital loss to report as a deduction, when you complete your tax return.

•Vanguard (or your intermediary) will send you a statement each year showing the tax status of all of your distributions.

Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to a 3.8% Medicare contribution tax on "net investment income." Net investment income takes into account distributions paid by the Fund and capital gains from any sale or exchange of Fund shares.

Dividend distributions and capital gains distributions that you receive, as well as your gains or losses from any sale or exchange of Fund shares, may be subject to state and local income taxes.

This prospectus provides general tax information only. If you are investing through a tax-advantaged account, such as an IRA or an employer-sponsored retirement or savings plan, special tax rules apply. Please consult your tax advisor for detailed information about any tax consequences for you.

Plain Talk About Buying a Dividend

Unless you are investing through a tax-advantaged account (such as an IRA or an employer-sponsored retirement or savings plan), you should consider avoiding a purchase of fund shares shortly before the fund makes a distribution, because doing so can cost you money in taxes. This is known as "buying a dividend." For example: On December 15, you invest $5,000, buying 250 shares for $20 each. If the fund pays a distribution of $1 per share on December 16, its share price will drop to $19 (not counting market change). You still have only $5,000 (250 shares x $19 = $4,750 in share value, plus 250 shares x $1 = $250 in distributions), but you owe tax on the $250 distribution you received—even if you reinvest it in more shares. To avoid buying a dividend, check a fund's distribution schedule before you invest.

General Information

Backup withholding. By law, Vanguard must withhold 24% of any taxable distributions or redemptions from your account if you do not:

•Provide your correct taxpayer identification number.

•Certify that the taxpayer identification number is correct.

•Confirm that you are not subject to backup withholding.

Similarly, Vanguard (or your intermediary) must withhold taxes from your account if the IRS instructs us to do so.

29

Foreign investors. Vanguard funds offered for sale in the United States (Vanguard U.S. funds), including the Fund offered in this prospectus, are not widely available outside the United States. Non-U.S. investors should be aware that U.S. withholding and estate taxes and certain U.S. tax reporting requirements may apply to any investments in Vanguard U.S. funds. Foreign investors should visit the non-U.S. investors page on our website at vanguard.com for information on Vanguard's non- U.S. products.

Invalid addresses. If a dividend distribution or capital gains distribution check mailed to your address of record is returned as undeliverable, Vanguard will automatically reinvest the distribution and all future distributions until you provide us with a valid mailing address. Reinvestments will receive the net asset value calculated on the date of the reinvestment.

Share Price

Share price, also known as net asset value (NAV), is calculated as of the close of regular trading on the New York Stock Exchange (NYSE), generally 4 p.m., Eastern time, on each day the NYSE is open for business (a business day). In the rare event the NYSE experiences unanticipated disruptions and is unavailable at the close of the trading day, the Fund reserves the right to treat such day as a business day and calculate NAVs as of the close of regular trading on the Nasdaq (or another alternate exchange if the Nasdaq is unavailable, as determined at Vanguard's discretion), generally 4 p.m., Eastern time. The NAV per share is computed by dividing the total assets, minus liabilities, of the Fund by the number of Fund shares outstanding. On U.S. holidays or other days when the NYSE is closed, the NAV is not calculated, and the Fund does not sell or redeem shares. However, on those days the value of the Fund's assets may be affected to the extent that the Fund holds securities that change in value on those days (such as foreign securities that trade on foreign markets that are open).

Stocks held by a Vanguard fund are valued at their market value when reliable market quotations are readily available from the principal exchange or market on which they are traded. Such securities are generally valued at their official closing price, the last reported sales price, or if there were no sales that day, the mean between the closing bid and asking prices. Debt securities held by a fund are valued based on information furnished by an independent pricing service or market quotations. When a fund determines that pricing-service information or market quotations either are not readily available or do not accurately reflect the value of a security, the security is priced at its fair value (the amount that the owner might reasonably expect to receive upon the current sale of the security).

The values of any foreign securities held by a fund are converted into U.S. dollars using an exchange rate obtained from an independent third party as of the close of

30

regular trading on the NYSE. The values of any mutual fund shares, including institutional money market fund shares, held by a fund are based on the NAVs of the shares. The values of any ETF shares or closed-end fund shares held by a fund are based on the market value of the shares.

A fund also will use fair-value pricing if the value of a security it holds has been materially affected by events occurring before the fund's pricing time but after the close of the principal exchange or market on which the security is traded. This most commonly occurs with foreign securities, which may trade on foreign exchanges that close many hours before the fund's pricing time. Intervening events might be company-specific (e.g., earnings report, merger announcement) or country-specific or regional/global (e.g., natural disaster, economic or political news, act of terrorism, interest rate change). Intervening events include price movements in U.S. markets that exceed a specified threshold or that are otherwise deemed to affect the value of foreign securities.

Fair-value pricing may be used for domestic securities—for example, if (1) trading in a security is halted and does not resume before the fund's pricing time or a security does not trade in the course of a day and (2) the fund holds enough of the security that its price could affect the NAV. A fund may use fair-value pricing with respect to its fixed income securities on bond market holidays when the fund is open for business (such as Columbus Day and Veterans Day).

Fair-value prices are determined by Vanguard according to procedures adopted by the board of trustees. When fair-value pricing is employed, the prices of securities used by a fund to calculate the NAV may differ from quoted or published prices for the same securities.

Vanguard fund share prices are published daily on our website at vanguard.com/prices.

Financial Highlights

Financial highlights information is intended to help you understand a fund's performance for the past five years (or, if shorter, its period of operations). Certain information reflects financial results for a single fund share. Total return represents the rate that an investor would have earned or lost each period on an investment in a fund or share class (assuming reinvestment of all distributions). This information has been obtained from the financial statements audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with fund financial statements, is included in a fund's most recent annual report to shareholders. You may obtain a free copy of a fund's latest annual or semiannual report, which is available upon request.

Investing With Vanguard

This section of the prospectus explains the basics of doing business with Vanguard. Vanguard fund shares can be held directly with Vanguard or indirectly through an intermediary, such as a bank, a broker, or an investment advisor. If you hold Vanguard fund shares directly with Vanguard, you should carefully read each topic within this section that pertains to your relationship with Vanguard. If you hold Vanguard fund shares indirectly through an intermediary including shares held in a brokerage account through Vanguard Brokerage Services®, please see Investing With Vanguard Through Other Firms, and also refer to your account agreement with the intermediary for information about transacting in that account. If you hold Vanguard fund shares through an employer-sponsored retirement or savings plan, please see Employer-Sponsored Plans. Vanguard reserves the right to change the following policies without notice. Please call or check online for current information. See Contacting Vanguard.

For Vanguard fund shares held directly with Vanguard, each fund you hold in an account is a separate "fund account." For example, if you hold three funds in a nonretirement account titled in your own name, two funds in a nonretirement account titled jointly with your spouse, and one fund in an individual retirement account, you have six fund accounts—and this is true even if you hold the same fund in multiple accounts. Note that each reference to "you" in this prospectus applies to any one or more registered account owners or persons authorized to transact on your account.

Purchasing Shares

Vanguard reserves the right, without notice, to increase or decrease the minimum amount required to open or maintain a fund account or to add to an existing fund account.

Investment minimums may differ for certain categories of investors.

If you are an intermediary who would like to open and maintain an account in the Fund, please note that Vanguard will require your written agreement to provide certain information about fund distributions to your clients on a periodic basis. Intermediaries who establish fund accounts without a written agreement may be prevented from making additional investments in those accounts. If you are an intermediary, please call Vanguard for instructions before you open an account in the Fund.

Account Minimums

To open and maintain an account. $50,000. Institutional clients should contact Vanguard for information on special eligibility rules that may apply to them.

To add to an existing account. Generally $1.

How to Initiate a Purchase Request

Be sure to check Exchanging Shares, Frequent-Trading Limitations, and Other Rules You Should Know before placing your purchase request.

Online. You may open certain types of accounts, request a purchase of shares, and request an exchange through our website or our mobile application if you are registered for online access.

By telephone. You may call Vanguard to begin the account registration process or request that the account-opening forms be sent to you. You may also call Vanguard to request a purchase of shares in your account or to request an exchange. See Contacting Vanguard.

By mail. You may send Vanguard your account registration form and check to open a new fund account. To add to an existing fund account, you may send your check with an Invest-by-Mail form (from a transaction confirmation or your account statement) or with a deposit slip (available online).

How to Pay for a Purchase

By electronic bank transfer. You may purchase shares of a Vanguard fund through an electronic transfer of money from a bank account. To establish the electronic bank transfer service on an account, you must designate the bank account online, complete a form, or fill out the appropriate section of your account registration form. After the service is set up on your account, you can purchase shares by electronic bank transfer on a regular schedule (Automatic Investment Plan) or upon request. Your purchase request can be initiated online (if you are registered for online access), by telephone, or by mail.

By wire. Wiring instructions vary for different types of purchases. Please call Vanguard for instructions and policies on purchasing shares by wire. See Contacting Vanguard.

By check. You may make initial or additional purchases to your fund account by sending a check with a deposit slip or by utilizing our mobile application if you are registered for online access. Also see How to Initiate a Purchase Request. Make your check payable to Vanguard and include the appropriate fund number (Vanguard—1298).

By exchange. You may purchase shares of a Vanguard fund using the proceeds from the simultaneous redemption of shares of another Vanguard fund. You may initiate an exchange online (if you are registered for online access), by telephone, or by mail with an exchange form. See Exchanging Shares.

Trade Date

The trade date for any purchase request received in good order will depend on the day and time Vanguard receives your request, the manner in which you are paying, and

35

the type of fund you are purchasing. Your purchase will be executed using the NAV as calculated on the trade date. See Share Price.

For purchases by check into all funds other than money market funds and for purchases by exchange, wire, or electronic bank transfer into all funds: If the purchase request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date for the purchase will be the same day. If the purchase request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date for the purchase will be the next business day.

For purchases by check into money market funds: If the purchase request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date for the purchase will be the next business day. If the purchase request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date for the purchase will be the second business day following the day Vanguard receives the purchase request. Because money market instruments must be purchased with federal funds and it takes a money market mutual fund one business day to convert check proceeds into federal funds, the trade date for the purchase will be one business day later than for other funds.

If your purchase request is not accurate and complete, it may be rejected. See Other Rules You Should Know—Good Order.

For further information about purchase transactions, consult our website at vanguard.com or see Contacting Vanguard.

Other Purchase Rules You Should Know

Check purchases. All purchase checks must be written in U.S. dollars, be drawn on a U.S. bank, and be accompanied by good order instructions. Vanguard does not accept cash, traveler's checks, starter checks, or money orders. In addition, Vanguard may refuse checks that are not made payable to Vanguard.

New accounts. We are required by law to obtain from you certain personal information that we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your identity, Vanguard reserves the right, without notice, to close your account or take such other steps as we deem reasonable. Certain types of accounts may require additional documentation.

Refused or rejected purchase requests. Vanguard reserves the right to stop selling fund shares or to reject any purchase request at any time and without notice, including, but not limited to, purchases requested by exchange from another Vanguard fund. This also includes the right to reject any purchase request because the investor has a

36

history of frequent trading or because the purchase may negatively affect a fund's operation or performance.

Large purchases. Call Vanguard before attempting to invest a large dollar amount.

No cancellations. Vanguard will not accept your request to cancel any purchase request once processing has begun. Please be careful when placing a purchase request.

Redeeming Shares

How to Initiate a Redemption Request

Be sure to check Exchanging Shares, Frequent-Trading Limitations, and Other Rules You Should Know before placing your redemption request.

Online. You may request a redemption of shares or request an exchange through our website or our mobile application if you are registered for online access.

By telephone. You may call Vanguard to request a redemption of shares or an exchange. See Contacting Vanguard.

By mail. You may send a form (available online) to Vanguard to redeem from a fund account or to make an exchange. See Contacting Vanguard.

How to Receive Redemption Proceeds

By electronic bank transfer. You may have the proceeds of a fund redemption sent directly to a designated bank account. To establish the electronic bank transfer service on an account, you must designate a bank account online, complete a form, or fill out the appropriate section of your account registration form. After the service is set up on your account, you can redeem shares by electronic bank transfer on a regular schedule (Automatic Withdrawal Plan) or upon request. Your redemption request can be initiated online (if you are registered for online access), by telephone, or by mail.

By wire. To receive your proceeds by wire, you may instruct Vanguard to wire your redemption proceeds ($100 minimum) to a previously designated bank account. To establish the wire redemption service, you generally must designate a bank account online, complete a form, or fill out the appropriate section of your account registration form.

Please note that Vanguard charges a $10 wire fee for outgoing wire redemptions. The fee is assessed in addition to, rather than being withheld from, redemption proceeds and is paid directly to the fund in which you invest. For example, if you redeem $100 via a wire, you will receive the full $100, and the $10 fee will be assessed to your fund account through an additional redemption of fund shares. If you redeem your entire fund account, your redemption proceeds will be reduced by the amount of the fee.

37

The wire fee does not apply to accounts held by Flagship and Flagship Select clients; accounts held through intermediaries, including Vanguard Brokerage Services; or accounts held by institutional clients.

By exchange. You may have the proceeds of a Vanguard fund redemption invested directly in shares of another Vanguard fund. You may initiate an exchange online (if you are registered for online access), by telephone, or by mail. See Exchanging Shares.

By check. If you have not chosen another redemption method, Vanguard will mail you a redemption check, generally payable to all registered account owners, normally within two business days of your trade date, and generally to the address of record.

Trade Date

The trade date for any redemption request received in good order will depend on the day and time Vanguard receives your request and the manner in which you are redeeming. Your redemption will be executed using the NAV as calculated on the trade date. See Share Price.

For redemptions by check, exchange, or wire: If the redemption request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the same day. If the redemption request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the next business day.

•Note on timing of wire redemptions from money market funds: For telephone requests received by Vanguard on a business day before 10:45 a.m., Eastern time (2 p.m., Eastern time, for Vanguard Prime Money Market Fund; 12:30 p.m., Eastern time, for Vanguard Federal Money Market Fund), the redemption proceeds generally will leave Vanguard by the close of business the same day. For telephone requests received by Vanguard on a business day after those cut-off times, or on a nonbusiness day, and for all requests other than by telephone, the redemption proceeds generally will leave Vanguard by the close of business on the next business day.

•Note on timing of wire redemptions from all other funds: For requests received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the redemption proceeds generally will leave Vanguard by the close of business on the next business day. For requests received by Vanguard on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the redemption proceeds generally will leave Vanguard by the close of business on the second business day after Vanguard receives the request.

For redemptions by electronic bank transfer: If the redemption request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the same day. If the redemption

38

request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the next business day.

If your redemption request is not accurate and complete, it may be rejected. If we are unable to send your redemption proceeds by wire or electronic bank transfer because the receiving institution rejects the transfer, Vanguard will make additional efforts to complete your transaction. If Vanguard is still unable to complete the transaction, we may send the proceeds of the redemption to you by check, generally payable to all registered account owners, or use your proceeds to purchase new shares of the fund from which you sold shares for the purpose of the wire or electronic bank transfer transaction. See Other Rules You Should Know—Good Order.

If your redemption request is received in good order, we typically expect that redemption proceeds will be paid by the Fund within one business day of the trade date; however, in certain circumstances, investors may experience a longer settlement period at the time of the transaction. For further information, see "Potentially disruptive redemptions" and "Emergency circumstances."

For further information about redemption transactions, consult our website at vanguard.com or see Contacting Vanguard.

Other Redemption Rules You Should Know

Documentation for certain accounts. Special documentation may be required to redeem from certain types of accounts, such as trust, corporate, nonprofit, or retirement accounts. Please call us before attempting to redeem from these types of accounts.

Potentially disruptive redemptions. Vanguard reserves the right to pay all or part of a redemption in kind—that is, in the form of securities—if we reasonably believe that a cash redemption would negatively affect the fund's operation or performance or that the shareholder may be engaged in market-timing or frequent trading. Under these circumstances, Vanguard also reserves the right to delay payment of the redemption proceeds for up to seven calendar days. By calling us before you attempt to redeem a large dollar amount, you may avoid in-kind or delayed payment of your redemption. Please see Frequent-Trading Limitations for information about Vanguard's policies to limit frequent trading.

Recently purchased shares. Although you can redeem shares at any time, proceeds may not be made available to you until the fund collects payment for your purchase. This may take up to seven calendar days for shares purchased by check or by electronic bank transfer. If you have written a check on a fund with checkwriting privileges, that check may be rejected if your fund account does not have a sufficient available balance.

39

Address change. If you change your address online or by telephone, there may be up to a 14-day restriction on your ability to request check redemptions online and by telephone. You can request a redemption in writing (using a form available online) at any time. Confirmations of address changes are sent to both the old and new addresses.

Payment to a different person or address. At your request, we can make your redemption check payable, or wire your redemption proceeds, to a different person or send it to a different address. However, this generally requires the written consent of all registered account owners and may require additional documentation, such as a signature guarantee or a notarized signature. You may obtain a signature guarantee from some commercial or savings banks, credit unions, trust companies, or member firms of a U.S. stock exchange.

No cancellations. Vanguard will not accept your request to cancel any redemption request once processing has begun. Please be careful when placing a redemption request.

Emergency circumstances. Vanguard funds can postpone payment of redemption proceeds for up to seven calendar days. In addition, Vanguard funds can suspend redemptions and/or postpone payments of redemption proceeds beyond seven calendar days at times when the NYSE is closed or during emergency circumstances, as determined by the SEC.

Exchanging Shares

An exchange occurs when you use the proceeds from the redemption of shares of one Vanguard fund to simultaneously purchase shares of a different Vanguard fund. You can make exchange requests online (if you are registered for online access), by telephone, or by mail. See Purchasing Shares and Redeeming Shares.

If the NYSE is open for regular trading (generally until 4 p.m., Eastern time, on a business day) at the time an exchange request is received in good order, the trade date generally will be the same day. See Other Rules You Should Know—Good Order for additional information on all transaction requests.

Vanguard will not accept your request to cancel any exchange request once processing has begun. Please be careful when placing an exchange request.

Call Vanguard before attempting to exchange a large dollar amount. By calling us before you attempt to exchange a large dollar amount, you may avoid delayed or rejected transactions.

Please note that Vanguard reserves the right, without notice, to revise or terminate the exchange privilege, limit the amount of any exchange, or reject an exchange, at

40

any time, for any reason. See Frequent-Trading Limitations for additional restrictions on exchanges.

Frequent-Trading Limitations

Because excessive transactions can disrupt management of a fund and increase the fund's costs for all shareholders, the board of trustees of each Vanguard fund places certain limits on frequent trading in the funds. Each Vanguard fund (other than money market funds and short-term bond funds, but including Vanguard Short-Term Inflation- Protected Securities Index Fund) limits an investor's purchases or exchanges into a fund account for 30 calendar days after the investor has redeemed or exchanged out of that fund account. ETF Shares are not subject to these frequent-trading limits.

For Vanguard Retirement Investment Program pooled plans, the limitations apply to exchanges made online or by telephone.

These frequent-trading limitations do not apply to the following:

•Purchases of shares with reinvested dividend or capital gains distributions.

•Transactions through Vanguard's Automatic Investment Plan, Automatic Exchange Service, Direct Deposit Service, Automatic Withdrawal Plan, Required Minimum Distribution Service, and Vanguard Small Business Online®.

•Discretionary transactions through Vanguard Personal Advisor Services®, Vanguard Institutional Advisory Services®, and Vanguard Digital AdvisorTM.

•Redemptions of shares to pay fund or account fees.

•Redemptions of shares to remove excess shareholder contributions to certain types of retirement accounts (including, but not limited to, IRAs and Vanguard Individual 401(k) Plans).

•Transfers and reregistrations of shares within the same fund.

•Purchases of shares by asset transfer or direct rollover.

•Conversions of shares from one share class to another in the same fund.

•Checkwriting redemptions.

•Section 529 college savings plans.

•Certain approved institutional portfolios and asset allocation programs, as well as trades made by funds or trusts managed by Vanguard or its affiliates that invest in other Vanguard funds. (Please note that shareholders of Vanguard's funds of funds are subject to the limitations.)

For participants in employer-sponsored defined contribution plans,* the frequent- trading limitations do not apply to:

41

•Purchases of shares with participant payroll or employer contributions or loan repayments.

•Purchases of shares with reinvested dividend or capital gains distributions.

•Distributions, loans, and in-service withdrawals from a plan.

•Redemptions of shares as part of a plan termination or at the direction of the plan.

•Transactions executed through the Vanguard Managed Account Program.

•Redemptions of shares to pay fund or account fees.

•Share or asset transfers or rollovers.

•Reregistrations of shares.

•Conversions of shares from one share class to another in the same fund.

•Exchange requests submitted by written request to Vanguard. (Exchange requests submitted by fax, if otherwise permitted, are subject to the limitations.)

*The following Vanguard fund accounts are subject to the frequent-trading limitations: SEP-IRAs, SIMPLE IRAs, certain Individual 403(b)(7) Custodial Accounts, and Vanguard Individual 401(k) Plans.

Accounts Held by Institutions (Other Than Defined Contribution Plans)

Vanguard will systematically monitor for frequent trading in institutional clients' accounts. If we detect suspicious trading activity, we will investigate and take appropriate action, which may include applying to a client's accounts the 30-day policy previously described, prohibiting a client's purchases of fund shares, and/or revoking the client's exchange privilege.

Accounts Held by Intermediaries

When intermediaries establish accounts in Vanguard funds for the benefit of their clients, we cannot always monitor the trading activity of the individual clients. However, we review trading activity at the intermediary (omnibus) level, and if we detect suspicious activity, we will investigate and take appropriate action. If necessary, Vanguard may prohibit additional purchases of fund shares by an intermediary, including for the benefit of certain of the intermediary's clients. Intermediaries also may monitor their clients' trading activities with respect to Vanguard funds.

For those Vanguard funds that charge purchase and/or redemption fees, intermediaries will be asked to assess these fees on client accounts and remit these fees to the funds. The application of purchase and redemption fees and frequent- trading limitations may vary among intermediaries. There are no assurances that Vanguard will successfully identify all intermediaries or that intermediaries will properly assess purchase and redemption fees or administer frequent-trading

42

limitations. If you invest with Vanguard through an intermediary, please read that firm's materials carefully to learn of any other rules or fees that may apply.

All such requests will receive trade dates as previously described in Purchasing Shares, Redeeming Shares, and Exchanging Shares. Vanguard reserves the right to return future-dated purchase checks.

Accounts With More Than One Owner

If an account has more than one owner or authorized person, Vanguard generally will accept instructions from any one owner or authorized person.

Responsibility for Fraud

You should take precautions to protect yourself from fraud. Keep your account-related information private, and review any account confirmations, statements, or other information that we provide to you as soon as you receive them. Let us know immediately if you discover unauthorized activity or see something on your account that you do not understand or that looks unusual.

Vanguard will not be responsible for losses that result from transactions by a person who we reasonably believe is authorized to act on your account.

44

Dormant Accounts

If your account has no activity in it for a period of time, Vanguard may be required to transfer it to a state under the state's abandoned property law, subject to potential federal or state withholding taxes.

Unusual Circumstances

If you experience difficulty contacting Vanguard online or by telephone, you can send us your transaction request on a Vanguard form by regular or express mail.

Investing With Vanguard Through Other Firms

You may purchase or sell shares of most Vanguard funds through a financial intermediary, such as a bank, a broker, or an investment advisor. Please consult your financial intermediary to determine which, if any, shares are available through that firm and to learn about other rules that may apply. Your financial intermediary can provide you with account information and any required tax forms. You may be required to pay a commission on purchases of mutual fund shares made through a financial intermediary.

Please see Frequent-Trading Limitations—Accounts Held by Intermediaries for information about the assessment of any purchase or redemption fees and the monitoring of frequent trading for accounts held by intermediaries.

Account Service Fee

Vanguard may charge a $20 account service fee on fund accounts that have a balance below $10,000 for any reason, including market fluctuation. The account service fee applies to both retirement and nonretirement fund accounts and may be assessed on fund accounts in all Vanguard funds, regardless of the account minimum. The fee, which will be collected by redeeming fund shares in the amount of $20, will be deducted from fund accounts subject to the fee once per calendar year.

If you elect to receive your statements and other materials electronically (i.e., by e-delivery), the account service fee will not be charged, so long as your election remains in effect. You can make your e-delivery election on vanguard.com.

Beginning on January 1, 2021, you may elect to receive paper copies of shareholder reports free of charge as noted on the cover of this prospectus.

45

Certain account types have alternative fee structures, including SIMPLE IRAs, Vanguard Retirement Investment Program pooled plans, and Vanguard Individual 401(k) Plans.

Low-Balance Accounts

The Fund reserves the right to liquidate a fund account whose balance falls below the account minimum for any reason, including market fluctuation. This liquidation policy applies to nonretirement fund accounts and accounts that are held through intermediaries. Any such liquidation will be preceded by written notice to the investor.

Right to Change Policies

In addition to the rights expressly stated elsewhere in this prospectus, Vanguard reserves the right, without notice, to (1) alter, add, or discontinue any conditions of purchase (including eligibility requirements), redemption, exchange, service, or privilege at any time and (2) alter, impose, discontinue, or waive any purchase fee, redemption fee, account service fee, or other fee charged to a shareholder or a group of shareholders. Changes may affect any or all investors. These actions will be taken when, at the sole discretion of Vanguard management, Vanguard believes they are in the best interest of a fund.

Account Restrictions

Vanguard reserves the right to: (1) redeem all or a portion of a fund/account to meet a legal obligation, including tax withholding, tax lien, garnishment order, or other obligation imposed on your account by a court or government agency; (2) redeem shares, close an account, or suspend account privileges, features, or options in the case of threatening conduct or activity; (3) redeem shares, close an account, or suspend account privileges, features, or options if Vanguard believes or suspects that not doing so could result in a suspicious, fraudulent, or illegal transaction; (4) place restrictions on the ability to redeem any or all shares in an account if it is required to do so by a court or government agency; (5) place restrictions on the ability to redeem any or all shares in an account if Vanguard believes that doing so will prevent fraud, financial exploitation or abuse, or to protect vulnerable investors; (6) freeze any account and/or suspend account services if Vanguard has received reasonable notice of a dispute regarding the assets in an account, including notice of a dispute between the registered or beneficial account owners; and (7) freeze any account and/or suspend account services upon initial notification to Vanguard of the death of an account owner.

Fund and Account Updates

Confirmation Statements

We will send (or provide through our website, whichever you prefer) a confirmation of your trade date and the amount of your transaction when you buy, sell, or exchange shares. However, we will not send confirmations reflecting only checkwriting redemptions or the reinvestment of dividend or capital gains distributions. For any month in which you had a checkwriting redemption, a Checkwriting Activity Statement will be sent to you itemizing the checkwriting redemptions for that month. Promptly review each confirmation statement that we provide to you. It is important that you contact Vanguard immediately with any questions you may have about any transaction reflected on a confirmation statement, or Vanguard will consider the transaction properly processed.

Promptly review each summary that we provide to you. It is important that you contact Vanguard immediately with any questions you may have about any transaction reflected on the summary, or Vanguard will consider the transaction properly processed.

Your plan's recordkeeper (which may also be Vanguard) will determine the necessary processing time frames for your transaction requests prior to submission to the Fund. Consult your recordkeeper or plan administrator for more information.

If Vanguard is serving as your plan recordkeeper and if your transaction involves one or more investments with an early cut-off time for processing or another trading restriction, your entire transaction will be subject to the restriction when the trade date for your transaction is determined.

Related Performance

Previously, the advisor managed an account ("Related Account") with investment objectives, policies, and strategies that were substantially similar to those of the Fund. The Related Account, however, was not subject to the investment limitations, diversification requirements, and other restrictions of the Investment Company Act of 1940 and the Internal Revenue Code, which, if applicable, may have adversely affected performance results. The Related Account ceased operations on July 31, 2015.

The performance of the Related Account does not represent the past performance of the Fund, and you should not consider the performance of the Related Account as indicative of the future performance of the Fund. The performance of the Fund may be greater than or less than the performance of the Related Account due to, among other things, the number of holdings in and composition of the Fund's portfolio, as well as the asset size and cash flow differences between the Fund and the Related Account.

Annual Total Returns of Related Account

The following bar chart and table set forth the performance of the Related Account, calculated net of actual fees and expenses. The bar chart shows how the performance of the Related Account has varied from one calendar year to another over the periods shown. The table shows how the average annual total returns of the Related Account compare with those of relevant market indexes. Keep in mind that the Related Account's past performance does not indicate how the Fund will perform in the future.

Shareholder Fees

(Fees paid directly from your investment)

Sales Charge (Load) Imposed on Purchases	None
Purchase Fee	None
Sales Charge (Load) Imposed on Reinvested Dividends	None
Redemption Fee	None
Account Service Fee (for certain fund account balances below $10,000)	$20/year
Annual Fund Operating Expenses
(Expenses that you pay each year as a percentage of the value of your investment)

Example

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you were to invest $10,000 in the Fund's shares. This example assumes that the Fund provides a return of 5% each year and that total annual fund operating expenses remain as stated in the preceding table. You would incur these hypothetical expenses whether or not you were to redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years	5 Years	10 Years
$20	$64	$113	$255

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund's performance. During the fiscal period from June 25, 2019 to October 31, 2019, the Fund's portfolio turnover rate was 7% of the average value of its portfolio.

Principal Investment Strategies

The Fund's advisor employs an active investment management approach to invest the Fund's assets in commodity-linked investments, which are backed by a portfolio of inflation-linked investments and other fixed income securities.

Commodities are real assets, including, but not limited to, agricultural products, livestock, precious and industrial metals, and energy products. The Fund invests in instruments that create long and short exposure to commodities, including commodity-linked total return swaps, commodity futures contracts and options on commodity futures contracts, commodity-linked structured notes, exchange-traded commodity pools or funds, and other commodity-linked derivative instruments. Particular commodity-linked investments may not necessarily conform to the composition, weighting, roll dates, reset dates, or contract months of the Fund's benchmark index or any other commodity market index.

The Fund intends to gain exposure to commodities by investing in a wholly owned subsidiary organized under the laws of the Cayman Islands (the subsidiary), which in turn invests in commodity-linked investments and fixed income securities. The Fund

2

may also invest directly in commodity-linked investments. The Fund will generally not invest more than 25% of its assets in the subsidiary.

The Fund invests the remainder of its assets in inflation-indexed bonds issued by the U.S. government, its agencies and instrumentalities, and corporations. The Fund may also invest in other fixed income securities, such as cash or cash equivalent investments and short-term bonds. At a minimum, all bonds purchased by the Fund will be investment-grade, or, if unrated, will be considered by the advisor to be investment-grade. The Fund's fixed income investments may provide liquidity for the Fund or serve as margin or collateral for its commodity-linked investments.

The Fund's use of certain commodity-linked investments is expected to have a leveraging effect on the Fund.

Principal Risks

An investment in the Fund could lose money over short, intermediate, or long periods of time. Returns may vary substantially over time, and there can be no guarantee that the Fund will achieve its investment objective or that its investment strategy will succeed.

The Fund's investment strategy involves the use of leverage, so its investment program may be considered speculative and is expected to involve considerable risks. The Fund could lose money at any time and may underperform the commodities markets during any given period, regardless of whether such markets rise or fall.

The Fund is subject to the risks described below. Each of these risks, alone or in combination with other risks, has the potential to hurt the Fund's performance, sometimes significantly.

•Commodity-linked investment risk, which is the chance that the Fund could lose all, or substantially all, of its investments in instruments linked to the returns of commodity investments. The commodities markets are volatile, and even a small movement in market prices could cause large losses. Prices of commodity-linked investments have a historically low correlation with the returns of the stock and bond markets and are subject to change based on a variety of factors that may not be anticipated by the Fund's advisor.

•Derivatives risk. The Fund's direct and indirect commodity-linked investments— such as commodity-linked total return swaps, commodity futures contracts and options on commodity futures contracts, commodity-linked structured notes, exchange-traded commodity pools or funds, and other commodity-linked derivative instruments—subject the Fund to risks associated with derivatives. The use of derivatives presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities. The use of derivatives can lead to losses because of adverse movements in the price or value of the underlying commodity or index. Derivative strategies often involve leverage, which may increase

3

a loss, potentially causing the Fund to lose more money than it would have lost had it invested in the underlying commodity or index. Also, a liquid market may not always exist for the Fund's derivative positions at times when the Fund might wish to terminate or sell such positions. In addition, regulators and futures exchanges have established limits, referred to as position limits, on the maximum net long or net short positions that any person may hold or control in particular derivative contracts. Some contract positions, such as commodity futures contracts, held by the Fund and/or the subsidiary may have to be liquidated at disadvantageous times or prices to avoid exceeding such position limits, which could adversely affect the Fund's total return. The use of a derivative subjects the investor to the risk of nonperformance by the counterparty (i.e., counterparty risk), potentially resulting in delayed or partial payment or even nonpayment of amounts due under the derivative contract.

•Tax risk, which is the chance that the Fund's commodity-linked investments could adversely affect the Fund's status as a regulated investment company.

•Inflation-linked investment risks. The Fund's annual income distributions are likely to fluctuate considerably. Under certain conditions, the Fund may not have any income to distribute. Income fluctuations associated with changes in interest rates are expected to be low; however, income fluctuations associated with changes in inflation are expected to be high. Overall, investors can expect income fluctuations to be high for the Fund. The Fund is also subject to interest rate risk, which is the chance that the value of a bond will fluctuate because of a change in the level of interest rates. Although inflation-indexed bonds seek to provide inflation protection, their prices may decline when interest rates rise and vice versa.

•Other fixed income investment risks. To the extent that the Fund invests in other fixed income securities, such as cash instruments or short-term bonds, the Fund is subject to income risk, credit risk, and call risk. These risks are described in the More on the Fund section of this prospectus.

•Subsidiary investment risk. The Fund is subject to risks associated with subsidiary investments. In particular, because the subsidiary is not organized as a mutual fund and is not registered under any federal or state securities laws (including the Investment Company Act of 1940), it does not offer the same investor protections available to shareholders of registered investment companies. In addition, the tax treatment of the Fund's investment in the subsidiary may be adversely affected by changes in the laws or regulations, or interpretations of existing laws or regulations, of the United States and/or the jurisdiction of the subsidiary. The Fund's ownership of the subsidiary subjects it to the same risks as if it were invested directly in the assets owned by the subsidiary. Risks associated with the subsidiary's underlying investments have been described elsewhere in this prospectus and include commodity-linked investment risk, derivatives risk, tax risk, inflation-linked investment risks, other fixed income investment risks, and manager risk.

4

•Leverage risk, which is the chance that any leveraged losses will exceed the principal amount invested by the Fund. Returns from a leveraged investment have the potential to be more volatile than returns from traditional stock and bond investments, which exposes the Fund to heightened risks.

•Manager risk, which is the chance that poor investment selection and/or poor strategy execution will cause the Fund and/or the subsidiary to fail to achieve its investment objective or generate lower returns than would be achieved from different investment selections. Poor investment selection by the advisor could also cause the Fund to underperform relevant benchmarks or other funds with similar investment objectives.

•Nondiversification risk, which is the chance that the Fund's performance may be hurt disproportionately by the performance of relatively few investments. The Fund is considered nondiversified, which means that it may invest a greater percentage of its assets in the instruments of particular issuers as compared with diversified mutual funds.

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

More on the Fund

This prospectus describes the principal risks you would face as a Fund shareholder. It is important to keep in mind one of the main principles of investing: generally, the higher the risk of losing money, the higher the potential reward. The reverse, also, is generally true: the lower the risk, the lower the potential reward. As you consider an investment in any mutual fund, you should take into account your personal tolerance

for fluctuations in the securities markets. Look for this symbol throughout the prospectus. It is used to mark detailed information about the more significant risks that you would confront as a Fund shareholder. To highlight terms and concepts important to mutual fund investors, we have provided Plain Talk® explanations along the way. Reading the prospectus will help you decide whether the Fund is the right investment for you. We suggest that you keep this prospectus for future reference.

Plain Talk About Fund Expenses

All mutual funds have operating expenses. These expenses, which are deducted from a fund's gross income, are expressed as a percentage of the net assets of the fund. Assuming that operating expenses remain as stated in the Fees and Expenses section, Vanguard Commodity Strategy Fund's expense ratio would be 0.20%, or $2.00 per $1,000 of average net assets.

Plain Talk About Costs of Investing

Costs are an important consideration in choosing a mutual fund. That is because you, as a shareholder, pay a proportionate share of the costs of operating a fund and any transaction costs incurred when the fund buys or sells securities. These costs can erode a substantial portion of the gross income or the capital appreciation a fund achieves. Even seemingly small differences in expenses can, over time, have a dramatic effect on a fund's performance.

The following sections explain the principal investment strategies and policies that the Fund uses in pursuit of its objective. The Fund's board of trustees, which oversees the Fund's management, may change investment strategies or policies in the interest of shareholders without a shareholder vote, unless those strategies or policies are designated as fundamental. Note that the Fund's investment objective is not fundamental and may be changed without a shareholder vote.

An investment in the Fund could lose money over any period of time. Returns may vary significantly over time, and there is no guarantee that the Fund will achieve its investment objective or that its investment strategy will succeed.

Market Exposure

The Fund seeks to provide broad commodities exposure and capital appreciation. To achieve this objective, the Fund's advisor employs an active investment management approach to invest the Fund's assets, either directly or indirectly through a wholly owned subsidiary, in commodity-linked investments. The Fund's commodity-linked investments are backed by a portfolio of inflation-linked investments and other fixed income securities.

• Commodity-Linked Investments

Commodities are real assets, including, but not limited to, agricultural products, livestock, precious and industrial metals, and energy products. The Fund does not invest in physical commodities, but rather in instruments that create both long and short exposure to commodities. These instruments include commodity-linked total return swaps, commodity futures contracts and options on commodity futures contracts, commodity-linked structured notes, exchange-traded commodity pools or funds, or other commodity-linked derivative instruments. Particular commodity-linked investments may not necessarily conform to the composition, weighting, roll dates, reset dates, or contract months of the Fund's benchmark index or any other commodity market index.

The Fund is subject to commodity-linked investment risk, which is the chance that the Fund could lose all, or substantially all, of its investments in instruments linked to the returns of commodity investments. The commodities markets are volatile, and even a small movement in market prices could cause large losses. Prices of commodity-linked investments have a historically low correlation with the returns of the stock and bond markets and are subject to change based on a variety of factors that may not be anticipated by the Fund's advisor.

Plain Talk About Commodities

Commodities are raw materials used to create the goods that consumers buy. They include a wide range of physical assets, such as agricultural products, livestock, precious metals, energy products, and industrial metals. Commodities can be purchased for immediate delivery ("on the spot") or delivery within a specific time period in the future under the terms of a futures contract. An exchange-traded commodity futures contract provides for the purchase and sale of a specified type and quantity of a commodity during a stated delivery month. A futures contract on an index of commodities provides for the payment and receipt of cash based on the level of the index at settlement or liquidation of the contract. Unlike equity securities, futures contracts, by their terms, have stated expirations, and at a specified time prior to expiration, trading in a futures contract for the current delivery month will cease. As a result, an investor wishing to maintain exposure to a futures contract on a particular commodity with the nearest expiration must close out a position in the expiring contract and establish a new position in the contract for the next delivery month. This process is referred to as "rolling." An investor will profit from rolling a futures contract if the cost for the new contract is lower than the cost of the expiring contract. Conversely, an investor will lose money by rolling a futures contract if the cost for the new contract is higher than the cost of the expiring contract.

The prices of commodity-linked investments are subject to change based on various factors, including, but not limited to, the following: lack of liquidity; global supply and demand for commodities; disorderly markets; limitations on deliverable supplies; the participation of hedgers and speculators; domestic and foreign interest rates and investors' expectations concerning interest rates; domestic and foreign inflation rates and investors' expectations concerning inflation rates; investment and trading activities of institutional investors; global or regional political, economic, or financial events and situations; government regulation and intervention; technical and operational or system failures; nuclear accident; terrorism; and natural disasters.

The Fund gains exposure to commodities primarily by investing in a wholly owned subsidiary organized under the laws of the Cayman Islands (the subsidiary), which in turn invests in commodity-linked investments and fixed income securities. The Fund may also invest directly in commodity-linked investments. The subsidiary's fixed income investments may include, but are not limited to, inflation-indexed securities, cash and cash equivalent investments, money market instruments, or other short- term instruments. Fixed income investments provide liquidity for the subsidiary and may serve as margin or collateral for the subsidiary's commodity-linked investments. The Fund's ownership of the subsidiary exposes it to the same risks as if it were invested directly in the assets owned by the subsidiary.

9

The Fund is subject to subsidiary investment risk, which is the risk that because the subsidiary is not registered under any federal or state securities laws, it does not offer the same investor protections available to shareholders of registered investment companies.

The subsidiary is not organized as a mutual fund, i.e., it is not registered under any federal or state securities laws, including the Investment Company Act of 1940 (1940 Act), and therefore is not subject to the investor protections of the 1940 Act.

There can be no assurance that the Fund will be permitted to continue to invest indirectly in commodity-linked investments through the subsidiary. Changes in the laws or regulations, or interpretations of existing laws or regulations, of the U.S. and/or the jurisdiction of the subsidiary could limit the Fund's ability to invest in the subsidiary, impact the way in which the subsidiary operates, increase the subsidiary's expenses, or otherwise adversely affect the Fund and/or the subsidiary. Moreover, the changes may be retroactive. For example, the subsidiary intends to operate in a manner that satisfies the Fund's qualifying income requirement under current U.S. tax law. However, there is no assurance that future changes in this law, or interpretations of this law, will not adversely affect the Fund. Also, although the subsidiary is not expected to owe income or other taxes in the jurisdiction in which it is organized, if that jurisdiction's tax laws were to change and the subsidiary were required to pay taxes, the Fund's investment returns could decrease. Because Vanguard receives asset-based fees from the subsidiary for services provided to the subsidiary, Fund assets invested in the subsidiary are excluded when allocating to the Fund its share of the costs of Vanguard's operations.

Tax risk is the chance that the Fund's commodity-linked investments could adversely affect the Fund's regulated investment company status.

The Fund's ability to make direct and indirect investments in commodity-linked investments, including in the subsidiary, is limited by the Fund's intention to qualify as a regulated investment company (RIC) under the Internal Revenue Code of 1986, as amended (the IRC), including the requirement that 90% of the Fund's gross income for each taxable year constitute "qualifying income." Additionally, as an RIC, the Fund may not invest more than 25% of its assets in the subsidiary.

The Fund generally intends to gain direct or indirect exposure to the commodities markets through investments that generate qualifying income under the IRC by investing directly in commodity-linked investments the Fund believes give rise to qualifying income, or by investing indirectly in commodity-linked investments through the subsidiary. However, if the Fund does not appropriately limit its investments in the subsidiary or in commodity-linked investments, or if the investments (or the income earned on the investments) are recharacterized for U.S. tax purposes, the Fund's status as an RIC may be jeopardized. Moreover, any recharacterization of these investments (or the income earned on these investments) may be retroactive. If the

10

Fund were to fail to qualify as an RIC in any taxable year, the Fund would be subject to Fund-level taxation, reducing the amount of income available for distribution to shareholders and reducing the net asset value of its shares.

Subsidiary manager risk is the chance that poor strategy execution will cause the subsidiary to fail to achieve its investment objective.

The subsidiary's success will depend on its advisor's ability to successfully invest in commodity-linked investments, such as commodity futures and commodity-linked total return swaps, and a combination of fixed income investments. The subsidiary is subject to the risk that it will not be successful in executing this strategy, and there is no guarantee that the subsidiary will achieve its investment objective. The subsidiary could lose money at any time.

The Fund's direct and indirect commodity-linked investments—such as commodity-linked total return swaps, commodities futures contracts and options on commodity futures contracts, commodity-linked structured notes, exchange-traded commodity pools or funds, and other commodity-linked derivative instruments—subject the Fund to risks associated with derivatives. Investments in derivatives may involve risks different from, and possibly greater than, those of investments directly in the underlying commodities or assets..

Losses involving certain derivatives can sometimes be substantial or even greater than the principal amount invested—in part because a relatively small price movement in such derivatives may result in an immediate and substantial loss to the investor. Derivatives also involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative may not correlate perfectly with the underlying securities, assets, reference rates, or indexes. The market for many derivatives is, or can suddenly become, illiquid, which may result in significant, rapid, and unpredictable changes in the prices for derivatives.

The use of certain derivatives subjects the investor to counterparty risk, which is the risk of nonperformance by the counterparty, potentially resulting in delayed or partial payment or even nonpayment of amounts due under the derivative contract. There are typically contractual remedies that may be pursued under a derivatives agreement in the event of default by a counterparty. The Fund and the subsidiary each expect to hold margin or collateral to secure the obligations of a counterparty in an effort to mitigate this risk.

11

 

Plain Talk About Derivatives

Generally speaking, a derivative is a financial contract whose value is based on the value of a financial asset (such as a stock, a bond, or a currency), a physical asset (such as gold, oil, or wheat), a market index, or a reference rate. Some forms of derivatives—such as exchange-traded futures and options on securities, commodities, or indexes—have been trading on regulated exchanges for decades. These types of derivatives are standardized contracts that can easily be bought and sold and whose market values are determined and published daily. On the other hand, non-exchange-traded derivatives—such as certain swap agreements and foreign currency exchange forward contracts—tend to be more specialized or complex and may be less liquid and more difficult to accurately value.

Liquidity risk is the chance that the markets, assets, and instruments in which the Fund invests are, or may become, illiquid.

The advisor expects that the Fund generally will seek to invest in liquid markets, assets, and instruments, although the Fund may have the ability to invest a portion of its assets in markets, assets, or instruments that are or may become illiquid. There is no assurance that investments that were liquid when purchased will not suddenly become illiquid for an indefinite period of time.

The Fund's use of commodity-linked derivative instruments is expected to have a leveraging effect on the Fund.

Leverage risk is the chance that any leveraged losses will exceed the principal amount invested by the Fund. Returns from a leveraged investment have the potential to be more volatile than returns from traditional stock and bond investments, which exposes the Fund to heightened risks.

Leverage exists when an investor has the right to a return on a total investment amount that exceeds the cash amount the investor contributed to the investment. Leverage magnifies the effect of gains and losses. The Fund's losses from its leveraged investments could be considerable.

Leverage-financing risk is the chance that the Fund will be unable to access and maintain financing sufficient to leverage its investments to targeted levels.

It is possible that the prime broker or other counterparties that finance the leverage employed by the Fund may not be willing or able to provide the level of financing that the advisor believes is required to implement the Fund's investment strategy.

12

• Inflation-Linked and Other Fixed Income Investments

The Fund's commodity-linked investments are backed by a portfolio of inflation-linked investments and other fixed income securities. These investments include inflation- indexed securities issued by the U.S. government, its agencies and instrumentalities, and corporations. The Fund may also invest in other fixed income securities, such as cash or cash equivalent investments, short-term bonds, or other debt securities.

Plain Talk About Inflation-Indexed Securities

Unlike a conventional bond, whose issuer makes regular fixed interest payments and repays the face value of the bond at maturity, an inflation-indexed security (IIS) provides principal and interest payments that are adjusted over time to reflect a rise (inflation) or a drop (deflation) in the general price level for goods and services. This adjustment is a key feature, given that inflation has typically occurred. However, there have been periods of deflation, such as in 1954 when the Consumer Price Index (CPI) declined by 0.7%. (Source: Bureau of Labor Statistics.) Importantly, in the event of deflation, the U.S. Treasury has guaranteed that it will repay at least the face value of an IIS issued by the U.S. government. However, if an IIS is purchased by a fund at a premium, deflation could cause a fund to experience a loss.

Inflation measurement and adjustment for an IIS have two important features. There is a two-month lag between the time that inflation occurs in the economy and when it is factored into IIS valuations. This is due to the time required to measure and calculate the CPI and for the U.S. Treasury to adjust the inflation accrual schedules for an IIS. For example, inflation that occurs in January is calculated and announced during February and affects IIS valuations throughout the month of March. In addition, the inflation index used is the nonseasonally adjusted index. It differs from the CPI that is reported by most news organizations, which is statistically smoothed to overcome highs and lows observed at different points each year. The use of the nonseasonally adjusted index can cause a fund's income level to fluctuate.

The Fund is subject to income fluctuations. The Fund's annual income distributions are likely to fluctuate considerably. In fact, under certain conditions, the Fund may not have any income to distribute. Income fluctuations associated with changes in interest rates are expected to be low; however, income fluctuations associated with changes in inflation are expected to be high. Overall, investors can expect income fluctuations to be high for the Fund.

13

Although fluctuations in the Fund's annual income distributions are expected to be high, distributions should provide an income yield that adjusts with inflation. In periods of extreme deflation, the Fund may have no income to distribute. If prices throughout the economy decline, the principal and income of an IIS will decline and could result in losses for the Fund.

Changes in interest rates can affect bond income as well as bond prices.

Plain Talk About Inflation-Indexed Securities and Interest Rates

Interest rates on conventional bonds have two primary components: a "real" yield and an increment that reflects investor expectations of future inflation. By contrast, interest rates on an IIS are adjusted for inflation and, therefore, are not affected meaningfully by inflation expectations. This leaves only real rates to influence the price of an IIS. A rise in real rates will cause the price of an IIS to fall, while a decline in real rates will boost the price of an IIS.

The Fund is subject to interest rate risk, which is the chance that the value of a bond will fluctuate because of a change in the level of interest rates. Although inflation-indexed bonds seek to provide inflation protection, their prices may decline when interest rates rise and vice versa.

Plain Talk About Real Returns

Inflation-indexed securities are designed to provide a "real rate of return"—a return after adjusting for the impact of inflation. Inflation—a rise in the general price level—erodes the purchasing power of an investor's portfolio. For example, if an investment provides a "nominal" total return of 5% in a given year and inflation is 2% during that period, the inflation-adjusted, or real, return is 3%. Investors should be conscious of both the nominal and the real returns on their investments. Investors in inflation-indexed bond funds who do not reinvest the portion of the income distribution that comes from inflation adjustments will not maintain the purchasing power of the investment over the long term. This is because interest earned depends on the amount of principal invested, and that principal will not grow with inflation if the investor does not reinvest the principal adjustment paid out as part of a fund's income distributions.

At a minimum, all bonds in which the Fund invests will be rated investment-grade, or, if unrated, will be considered by the advisor to be investment-grade.

14

The Fund may be subject to credit risk, which is the chance that a bond issuer will fail to pay interest or principal in a timely manner or that negative perceptions of the issuer's ability to make such payments will cause the price of that bond to decline.

Plain Talk About Credit Quality

A bond's credit quality rating is an assessment of the issuer's ability to pay interest on the bond and, ultimately, to repay the principal. The lower the credit quality, the greater the perceived chance that the bond issuer will default, or fail to meet its payment obligations. All things being equal, the lower a bond's credit quality, the higher its yield should be to compensate investors for assuming additional risk.

To the extent that the Fund invests in other fixed income investments, such as cash instruments, short-term bonds, or other debt securities, the Fund is subject to income risk and call risk.

The Fund may be subject to income risk, which is the chance that the Fund's income will decline because of falling interest rates. A fund holding bonds will experience a decline in income when interest rates fall because the fund then must invest new cash flow and cash from maturing bonds in lower-yielding bonds. Income risk is generally higher for funds holding short-term bonds than for funds holding long-term bonds.

The Fund may be subject to call risk, which is the chance that during periods of falling interest rates, issuers of callable bonds may call (redeem) securities with higher coupon rates or interest rates before their maturity dates. If the Fund holds a bond that is called, the Fund would then lose any price appreciation above the bond's call price and would be forced to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund's income.

Security Selection

Vanguard manages the Fund through the use of a continually evolving process that was developed and is managed by Vanguard's Quantitative Equity Group. All potential enhancements to the process go through rigorous vetting and validation before being implemented. The portfolio managers use the resulting process to determine which instruments to buy long and sell short for the portfolio.

15

The Fund is subject to manager risk, which is the chance that poor investment selections and/or poor strategy execution by the advisor will cause the Fund to fail to achieve its investment objective or to generate lower returns than would be achieved from different investment selections. Poor investment selection by the advisor could also cause the Fund to underperform relevant benchmarks or other funds with similar investment objectives.

While the Fund predominantly holds long positions, the Fund's performance depends on the net returns of its long and short positions. It is possible for the Fund to experience a net loss across all positions. If the Fund's investment program is successful, however, the net returns of its long and short positions will produce long- term capital appreciation.

The Fund is subject to nondiversification risk, which is the chance that the Fund's performance may be hurt disproportionately by the poor performance of relatively few investments. The Fund is considered nondiversified, which means that it may invest a greater percentage of its assets in the instruments of particular issuers as compared with diversified mutual funds.

Other Investment Policies and Risks

In addition to investing in commodity-linked investments, inflation-linked investments, and other fixed income securities, the Fund may make other kinds of investments to achieve its investment objective.

The Fund may invest up to 15% of its net assets in illiquid securities. Illiquid securities are investments that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. Restricted securities are a special type of illiquid security; these securities have not been publicly issued and legally can be resold only to qualified buyers. From time to time, the board of trustees may determine that particular restricted securities are not illiquid, and those securities may then be purchased by the Fund without limit.

The Fund may invest a portion of its assets in fixed income futures, which are a type of derivative, and/or shares of exchange-traded funds (ETFs). These fixed income futures and ETFs typically provide returns similar to those of bonds. The Fund may purchase fixed income futures or ETFs when doing so will reduce the Fund's transaction costs, facilitate cash management, mitigate risk, or have the potential to add value because the instruments are favorably priced. Vanguard receives no additional revenue from Fund assets invested in ETF Shares of other Vanguard funds. Fund assets invested in ETF Shares are excluded when allocating to the Fund its share of the costs of Vanguard operations.

16

Cash Management

The Fund's daily cash balance may be invested in Vanguard Market Liquidity Fund and/or Vanguard Municipal Cash Management Fund (each, a CMT Fund), which are low-cost money market funds. When investing in a CMT Fund, the Fund bears its proportionate share of the expenses of the CMT Fund in which it invests. Vanguard receives no additional revenue from Fund assets invested in a CMT Fund.

Methods Used to Meet Redemption Requests

Under normal circumstances, the Fund typically expects to meet redemptions with positive cash flows. When this is not an option, the Fund seeks to maintain its risk exposure by selling a cross section of the Fund's holdings to meet redemptions, while also factoring in transaction costs. Additionally, the Fund may work with larger clients to implement their redemptions in a manner that is least disruptive to the portfolio; see "Potentially disruptive redemptions" under Redeeming Shares in the Investing With Vanguard section.

Under certain circumstances, including under stressed market conditions, there are additional tools that the Fund may use in order to meet redemptions, including advancing the settlement of market trades with counterparties to match investor redemption payments or delaying settlement of an investor's transaction to match trade settlement within regulatory requirements. The Fund may also suspend payment of redemption proceeds for up to seven days; see "Emergency circumstances" under Redeeming Shares in the Investing With Vanguard section. Additionally under these unusual circumstances, the Fund may borrow money (subject to certain regulatory conditions and if available under board-approved procedures) through an interfund lending facility or through a bank line-of-credit, including a joint committed credit facility, in order to meet redemption requests.

Temporary Investment Measures

The Fund may temporarily depart from its normal investment policies and strategies when the advisor believes that doing so is in the Fund's best interest, so long as the strategy or policy employed is consistent with the Fund's investment objective. For instance, the Fund may invest beyond its normal limits in derivatives or exchange- traded funds that are consistent with the Fund's investment objective when those instruments are more favorably priced or provide needed liquidity, as might be the case if the Fund is transitioning assets from one advisor to another or receives large cash flows that it cannot prudently invest immediately.

In addition, the Fund may take temporary defensive positions that are inconsistent with its normal investment policies and strategies—for instance, by allocating substantial assets to cash equivalent investments or other less volatile instruments— in response to adverse or unusual market, economic, political, or other conditions. In

17

doing so, the Fund may succeed in avoiding losses but may otherwise fail to achieve its investment objective.

Frequent Trading or Market-Timing

Background. Some investors try to profit from strategies involving frequent trading of mutual fund shares, such as market-timing. For funds holding foreign securities, investors may try to take advantage of an anticipated difference between the price of the fund's shares and price movements in overseas markets, a practice also known as time-zone arbitrage. Investors also may try to engage in frequent trading of funds holding investments such as small-cap stocks and high-yield bonds. As money is shifted into and out of a fund by a shareholder engaging in frequent trading, the fund incurs costs for buying and selling securities, resulting in increased brokerage and administrative costs. These costs are borne by all fund shareholders, including the long-term investors who do not generate the costs. In addition, frequent trading may interfere with an advisor's ability to efficiently manage the fund.

Policies to address frequent trading. The Vanguard funds (other than money market funds and short-term bond funds, but including Vanguard Short-Term Inflation- Protected Securities Index Fund) do not knowingly accommodate frequent trading. The board of trustees of each Vanguard fund (other than money market funds and short- term bond funds, but including Vanguard Short-Term Inflation-Protected Securities Index Fund) has adopted policies and procedures reasonably designed to detect and discourage frequent trading and, in some cases, to compensate the fund for the costs associated with it. These policies and procedures do not apply to ETF Shares because frequent trading in ETF Shares generally does not disrupt portfolio management or otherwise harm fund shareholders. Although there is no assurance that Vanguard will be able to detect or prevent frequent trading or market-timing in all circumstances, the following policies have been adopted to address these issues:

•Each Vanguard fund reserves the right to reject any purchase request—including exchanges from other Vanguard funds—without notice and regardless of size. For example, a purchase request could be rejected because the investor has a history of frequent trading or if Vanguard determines that such purchase may negatively affect a fund's operation or performance.

•Each Vanguard fund (other than money market funds and short-term bond funds, but including Vanguard Short-Term Inflation-Protected Securities Index Fund) generally prohibits, except as otherwise noted in the Investing With Vanguard section, an investor's purchases or exchanges into a fund account for 30 calendar days after the investor has redeemed or exchanged out of that fund account.

•Certain Vanguard funds charge shareholders purchase and/or redemption fees on transactions.

18

See the Investing With Vanguard section of this prospectus for further details on Vanguard's transaction policies.

Each Vanguard fund (other than retail and government money market funds), in determining its net asset value, will use fair-value pricing when appropriate, as described in the Share Price section. Fair-value pricing may reduce or eliminate the profitability of certain frequent-trading strategies.

Do not invest with Vanguard if you are a market-timer.

Turnover Rate

Although the Fund generally seeks to invest for the long term, it may sell securities regardless of how long they have been held. The Financial Highlights section of this prospectus shows historical turnover rates for the Fund. A turnover rate of 100%, for example, would mean that the Fund had sold and replaced securities valued at 100% of its net assets within a one-year period. In general, the greater the turnover rate, the greater the impact transaction costs will have on a fund's return. Also, funds with high turnover rates may be more likely to generate capital gains, including short-term capital gains, that must be distributed to shareholders and will be taxable to shareholders investing through a taxable account.

The Fund and Vanguard

The Fund is a member of The Vanguard Group, a family of over 200 funds. All of the funds that are members of The Vanguard Group (other than funds of funds) share in the expenses associated with administrative services and business operations, such as personnel, office space, and equipment.

Vanguard Marketing Corporation provides marketing services to the funds. Although fund shareholders do not pay sales commissions or 12b-1 distribution fees, each fund (other than a fund of funds) or each share class of a fund (in the case of a fund with multiple share classes) pays its allocated share of the Vanguard funds' marketing costs.

Plain Talk About Vanguard's Unique Corporate Structure

The Vanguard Group is owned jointly by the funds it oversees and thus indirectly by the shareholders in those funds. Most other mutual funds are operated by management companies that are owned by third parties—either public or private stockholders—and not by the funds they serve.

19

Investment Advisor

The Vanguard Group, Inc., P.O. Box 2600, Valley Forge, PA 19482, which began operations in 1975, serves as advisor to the Fund through its Quantitative Equity Group and its Fixed Income Group. As of October 31, 2019, Vanguard served as advisor for approximately $4.7 trillion in assets. Vanguard provides investment advisory services to the Fund pursuant to the Funds' Service Agreement and subject to the supervision and oversight of the trustees and officers of the Fund.

For the fiscal period ended October 31, 2019, the advisory expenses represented an effective annual rate of 0.01% of the Fund's average net assets.

Under the terms of an SEC exemption, the Fund's board of trustees may, without prior approval from shareholders, change the terms of an advisory agreement with a third-party investment advisor or hire a new third-party investment advisor—either as a replacement for an existing advisor or as an additional advisor. Any significant change in the Fund's advisory arrangements will be communicated to shareholders in writing. As the Fund's sponsor and overall manager, Vanguard may provide investment advisory services to the Fund at any time. Vanguard may also recommend to the board of trustees that an advisor be hired, terminated, or replaced or that the terms of an existing advisory agreement be revised. The Fund has filed an application seeking a similar SEC exemption with respect to investment advisors that are wholly owned subsidiaries of Vanguard. If the exemption is granted, the Fund may rely on the new SEC relief.

For a discussion of why the board of trustees approved the Fund's investment advisory arrangement, see the annual report to shareholders covering the fiscal period ended October 31, 2019, which will be available 60 days after that date.

The managers primarily responsible for the day-to-day management of the Fund are:

Anatoly Shtekhman, CFA, Portfolio Manager at Vanguard. He has been with Vanguard since 2007, has managed investment portfolios since 2016, and has co-managed the Fund since its inception in 2019. Education: B.S., University of Scranton; M.S., Boston College; M.B.A., The Wharton School of the University of Pennsylvania.

Fei Xu, CFA, Portfolio Manager at Vanguard. He has been with Vanguard since 2004, has managed investment portfolios since 2017, and has co-managed the Fund since its inception in 2019. Education: B.S., Peking University; M.S., University of California, Los Angeles; M.B.A., Duke University.

Joshua C. Barrickman, CFA, Principal of Vanguard and co-head of Vanguard's Fixed Income Indexing Americas. He has been with Vanguard since 1998, has worked in investment management since 1999, has managed investment portfolios since 2005, and has co-managed the Fund since its inception in 2019. Education: B.S., Ohio Northern University; M.B.A., Lehigh University.

The Fund's Statement of Additional Information provides information about each portfolio manager's compensation, other accounts under management, and ownership of shares of the Fund.

Dividends, Capital Gains, and Taxes

Fund Distributions

The Fund distributes to shareholders virtually all of its net income (interest and dividends, less expenses) as well as any net short-term or long-term capital gains realized from the sale of its holdings. From time to time, the Fund may also make distributions that are treated as a return of capital. Income and capital gains distributions, if any, generally occur annually in December. In addition, the Fund may occasionally make a supplemental distribution at some other time during the year. However, the special tax treatment applicable to the Fund's investments in inflation- indexed bonds increases the Fund's risk of overdistributing income and paying a return of capital for the year.

You can receive distributions of income or capital gains in cash, or you can have them automatically reinvested in more shares of the Fund. However, if you are investing through an employer-sponsored retirement or savings plan, your distributions will be automatically reinvested in additional Fund shares.

Plain Talk About Distributions

As a shareholder, you are entitled to your portion of a fund's income from interest as well as capital gains from the fund's sale of investments. Income consists of, among other things, interest the fund earns from its fixed income investments. Capital gains are realized whenever the fund sells investments for higher prices than it paid for them. These capital gains are either short-term or long-term, depending on whether the fund held the investments for one year or less or for more than one year.

21

 

Plain Talk About Return of Capital

Return of capital is the portion of a distribution representing the return of your original investment in a fund. Return of capital reduces your cost basis in the fund's shares and is not taxable to you until your cost basis has been reduced to zero. During periods of deflation, the fund's inflation-indexed bonds may experience a downward adjustment in their value. These downward adjustments can partially or entirely offset, or more than offset, the income earned on the bonds. Under certain circumstances, these downward adjustments could require the fund to reclassify a portion of the income dividends previously distributed to shareholders as return of capital.

Basic Tax Points

Investors in taxable accounts should be aware of the following basic federal income tax points:

•Distributions are taxable to you whether or not you reinvest these amounts in additional Fund shares.

•Distributions declared in December—if paid to you by the end of January—are taxable as if received in December.

•Any income distribution or short-term capital gains distribution that you receive is taxable to you as ordinary income.

•Any distribution of net long-term capital gains is taxable to you as long-term capital gains, no matter how long you have owned shares in the Fund.

•Capital gains distributions may vary considerably from year to year as a result of the Fund's normal investment activities and cash flows.

•Your cost basis in the Fund will be decreased by the amount of any return of capital that you receive. This, in turn, will affect the amount of any capital gain or loss that you realize when selling or exchanging your Fund shares.

•Return of capital distributions generally are not taxable to you until your cost basis has been reduced to zero. If your cost basis is at zero, return of capital distributions will be treated as capital gains.

•A sale or exchange of Fund shares is a taxable event. This means that you may have a capital gain to report as income, or a capital loss to report as a deduction, when you complete your tax return.

•Any conversion between classes of shares of the same fund is a nontaxable event. By contrast, an exchange between classes of shares of different funds is a taxable event.

22

•Vanguard (or your intermediary) will send you a statement each year showing the tax status of all of your distributions.

Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to a 3.8% Medicare contribution tax on "net investment income." Net investment income takes into account distributions paid by the Fund and capital gains from any sale or exchange of Fund shares.

Income dividends and capital gains distributions that you receive, as well as your gains or losses from any sale or exchange of Fund shares, may be subject to state and local income taxes. Depending on your state's rules, however, any dividends attributable to interest earned on direct obligations of the U.S. government may be exempt from state and local taxes. Vanguard will notify you each year how much, if any, of your dividends may qualify for this exemption.

This prospectus provides general tax information only. If you are investing through a tax-advantaged account, such as an IRA or an employer-sponsored retirement or savings plan, special tax rules apply. Please consult your tax advisor for detailed information about any tax consequences for you.

Plain Talk About Buying a Dividend

Unless you are a tax-exempt investor or investing through a tax-advantaged account (such as an IRA or an employer-sponsored retirement or savings plan), you should consider avoiding a purchase of fund shares shortly before the fund makes a distribution, because doing so can cost you money in taxes. This is known as "buying a dividend." For example: On December 15, you invest $5,000, buying 250 shares for $20 each. If the fund pays a distribution of $1 per share on December 16, its share price will drop to $19 (not counting market change). You still have only $5,000 (250 shares x $19 = $4,750 in share value, plus 250 shares x $1 = $250 in distributions), but you owe tax on the $250 distribution you received—even if you reinvest it in more shares. To avoid buying a dividend, check a fund's distribution schedule before you invest.

23

General Information

Backup withholding. By law, Vanguard must withhold 24% of any taxable distributions or redemptions from your account if you do not:

•Provide your correct taxpayer identification number.

•Certify that the taxpayer identification number is correct.

•Confirm that you are not subject to backup withholding.

Similarly, Vanguard (or your intermediary) must withhold taxes from your account if the IRS instructs us to do so.

Foreign investors. Vanguard funds offered for sale in the United States (Vanguard U.S. funds), including the Fund offered in this prospectus, are not widely available outside the United States. Non-U.S. investors should be aware that U.S. withholding and estate taxes and certain U.S. tax reporting requirements may apply to any investments in Vanguard U.S. funds. Foreign investors should visit the non-U.S. investors page on our website at vanguard.com for information on Vanguard's non-U.S. products.

Invalid addresses. If an income distribution or capital gains distribution check mailed to your address of record is returned as undeliverable, Vanguard will automatically reinvest the distribution and all future distributions until you provide us with a valid mailing address. Reinvestments will receive the net asset value calculated on the date of the reinvestment.

Share Price

Share price, also known as net asset value (NAV), is calculated as of the close of regular trading on the New York Stock Exchange (NYSE), generally 4 p.m., Eastern time, on each day that the NYSE is open for business (a business day). In the rare event the NYSE experiences unanticipated disruptions and is unavailable at the close of the trading day, the Fund reserves the right to treat such day as a business day and calculate NAVs as of the close of regular trading on the Nasdaq (or another alternate exchange if the Nasdaq is unavailable, as determined at Vanguard's discretion), generally 4 p.m., Eastern time. The NAV per share is computed by dividing the total assets, minus liabilities, of the Fund by the number of Fund shares outstanding. On U.S. holidays or other days when the NYSE is closed, the NAV is not calculated, and the Fund does not sell or redeem shares.

Debt securities held by a Vanguard fund are valued based on information furnished by an independent pricing service or market quotations. When a fund determines that pricing-service information or market quotations either are not readily available or do not accurately reflect the value of a security, the security is priced at its fair value (the amount that the owner might reasonably expect to receive upon the current sale of the security).

24

The values of any foreign securities held by a fund are converted into U.S. dollars using an exchange rate obtained from an independent third party as of the close of regular trading on the NYSE. The values of any mutual fund shares, including institutional money market fund shares, held by a fund are based on the NAVs of the shares. The values of any ETF shares or closed-end fund shares held by a fund are based on the market value of the shares.

A fund also may use fair-value pricing on bond market holidays when the fund is open for business (such as Columbus Day and Veterans Day). Fair-value prices are determined by Vanguard according to procedures adopted by the board of trustees. When fair-value pricing is employed, the prices of securities used by a fund to calculate the NAV may differ from quoted or published prices for the same securities.

Vanguard fund share prices are published daily on our website at vanguard.com/prices.

Financial Highlignts

Financial highlights information is intended to help you understand a fund's performance for the past five years (or, if shorter, its period of operations). Certain information reflects financial results for a single fund share. Total return represents the rate that an investor would have earned or lost each period on an investment in a fund or share class (assuming reinvestment of all distributions). This information has been obtained from the financial statements audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with fund financial statements, is included in a fund's most recent annual report to shareholders. You may obtain a free copy of a fund's latest annual or semiannual report, which is available upon request.

Investing With Vanguard

This section of the prospectus explains the basics of doing business with Vanguard. Vanguard fund shares can be held directly with Vanguard or indirectly through an intermediary, such as a bank, a broker, or an investment advisor. If you hold Vanguard fund shares directly with Vanguard, you should carefully read each topic within this section that pertains to your relationship with Vanguard. If you hold Vanguard fund shares indirectly through an intermediary (including shares held in a brokerage account through Vanguard Brokerage Services®), please see Investing With Vanguard Through Other Firms, and also refer to your account agreement with the intermediary for information about transacting in that account. If you hold Vanguard fund shares through an employer-sponsored retirement or savings plan, please see Employer-Sponsored Plans. Vanguard reserves the right to change the following policies without notice. Please call or check online for current information. See Contacting Vanguard.

For Vanguard fund shares held directly with Vanguard, each fund you hold in an account is a separate "fund account." For example, if you hold three funds in a nonretirement account titled in your own name, two funds in a nonretirement account titled jointly with your spouse, and one fund in an individual retirement account, you have six fund accounts—and this is true even if you hold the same fund in multiple accounts. Note that each reference to "you" in this prospectus applies to any one or more registered account owners or persons authorized to transact on your account.

Purchasing Shares

Vanguard reserves the right, without notice, to increase or decrease the minimum amount required to open or maintain a fund account or to add to an existing fund account.

Investment minimums may differ for certain categories of investors.

Account Minimums for Admiral Shares

To open and maintain an account. $50,000. Institutional clients should contact Vanguard for information on special eligibility rules that may apply to them regarding Admiral Shares.

To add to an existing account. Generally $1.

How to Initiate a Purchase Request

Be sure to check Exchanging Shares, Frequent-Trading Limitations, and Other Rules You Should Know before placing your purchase request.

Online. You may open certain types of accounts, request a purchase of shares, and request an exchange through our website or our mobile application if you are registered for online access.

27

By telephone. You may call Vanguard to begin the account registration process or request that the account-opening forms be sent to you. You may also call Vanguard to request a purchase of shares in your account or to request an exchange. See Contacting Vanguard.

By mail. You may send Vanguard your account registration form and check to open a new fund account. To add to an existing fund account, you may send your check with an Invest-by-Mail form (from a transaction confirmation or your account statement) or with a deposit slip (available online).

How to Pay for a Purchase

By electronic bank transfer. You may purchase shares of a Vanguard fund through an electronic transfer of money from a bank account. To establish the electronic bank transfer service on an account, you must designate the bank account online, complete a form, or fill out the appropriate section of your account registration form. After the service is set up on your account, you can purchase shares by electronic bank transfer on a regular schedule (Automatic Investment Plan) or upon request. Your purchase request can be initiated online (if you are registered for online access), by telephone, or by mail.

By wire. Wiring instructions vary for different types of purchases. Please call Vanguard for instructions and policies on purchasing shares by wire. See Contacting Vanguard.

By check. You may make initial or additional purchases to your fund account by sending a check with a deposit slip or by utilizing our mobile application if you are registered for online access. Also see How to Initiate a Purchase Request. Make your check payable to Vanguard and include the appropriate fund number (Vanguard—517).

By exchange. You may purchase shares of a Vanguard fund using the proceeds from the simultaneous redemption of shares of another Vanguard fund. You may initiate an exchange online (if you are registered for online access), by telephone, or by mail with an exchange form. See Exchanging Shares.

Trade Date

The trade date for any purchase request received in good order will depend on the day and time Vanguard receives your request, the manner in which you are paying, and the type of fund you are purchasing. Your purchase will be executed using the NAV as calculated on the trade date. See Share Price.

For purchases by check into all funds other than money market funds and for purchases by exchange, wire, or electronic bank transfer into all funds: If the purchase request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date for the purchase will be the same day. If the purchase request is received on a business day

28

after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date for the purchase will be the next business day.

For purchases by check into money market funds: If the purchase request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date for the purchase will be the next business day. If the purchase request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date for the purchase will be the second business day following the day Vanguard receives the purchase request. Because money market instruments must be purchased with federal funds and it takes a money market mutual fund one business day to convert check proceeds into federal funds, the trade date for the purchase will be one business day later than for other funds.

If your purchase request is not accurate and complete, it may be rejected. See Other Rules You Should Know—Good Order.

For further information about purchase transactions, consult our website at vanguard.com or see Contacting Vanguard.

Refused or rejected purchase requests. Vanguard reserves the right to stop selling fund shares or to reject any purchase request at any time and without notice, including, but not limited to, purchases requested by exchange from another Vanguard fund. This also includes the right to reject any purchase request because the investor has a history of frequent trading or because the purchase may negatively affect a fund's operation or performance.

Large purchases. Call Vanguard before attempting to invest a large dollar amount.

29

No cancellations. Vanguard will not accept your request to cancel any purchase request once processing has begun. Please be careful when placing a purchase request.

Redeeming Shares

How to Initiate a Redemption Request

Be sure to check Exchanging Shares, Frequent-Trading Limitations, and Other Rules You Should Know before placing your redemption request.

Online. You may request a redemption of shares or request an exchange through our website or our mobile application if you are registered for online access.

By telephone. You may call Vanguard to request a redemption of shares or an exchange. See Contacting Vanguard.

By mail. You may send a form (available online) to Vanguard to redeem from a fund account or to make an exchange.

How to Receive Redemption Proceeds

By electronic bank transfer. You may have the proceeds of a fund redemption sent directly to a designated bank account. To establish the electronic bank transfer service on an account, you must designate a bank account online, complete a form, or fill out the appropriate section of your account registration form. After the service is set up on your account, you can redeem shares by electronic bank transfer on a regular schedule (Automatic Withdrawal Plan) or upon request. Your redemption request can be initiated online (if you are registered for online access), by telephone, or by mail.

By wire. To receive your proceeds by wire, you may instruct Vanguard to wire your redemption proceeds ($100 minimum) to a previously designated bank account. To establish the wire redemption service, you generally must designate a bank account online, complete a form, or fill out the appropriate section of your account registration form.

Please note that Vanguard charges a $10 wire fee for outgoing wire redemptions. The fee is assessed in addition to, rather than being withheld from, redemption proceeds and is paid directly to the fund in which you invest. For example, if you redeem $100 via a wire, you will receive the full $100, and the $10 fee will be assessed to your fund account through an additional redemption of fund shares. If you redeem your entire fund account, your redemption proceeds will be reduced by the amount of the fee. The wire fee does not apply to accounts held by Flagship and Flagship Select clients; accounts held through intermediaries, including Vanguard Brokerage Services; or accounts held by institutional clients.

30

By exchange. You may have the proceeds of a Vanguard fund redemption invested directly in shares of another Vanguard fund. You may initiate an exchange online (if you are registered for online access), by telephone, or by mail. See Exchanging Shares.

By check. If you have not chosen another redemption method, Vanguard will mail you a redemption check, generally payable to all registered account owners, normally within two business days of your trade date, and generally to the address of record.

Trade Date

The trade date for any redemption request received in good order will depend on the day and time Vanguard receives your request and the manner in which you are redeeming. Your redemption will be executed using the NAV as calculated on the trade date. See Share Price.

For redemptions by check, exchange, or wire: If the redemption request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the same day. If the redemption request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the next business day.

•Note on timing of wire redemptions from money market funds: For telephone requests received by Vanguard on a business day before 10:45 a.m., Eastern time (2 p.m., Eastern time, for Vanguard Prime Money Market Fund; 12:30 p.m., Eastern time, for Vanguard Federal Money Market Fund), the redemption proceeds generally will leave Vanguard by the close of business the same day. For telephone requests received by Vanguard on a business day after those cut-off times, or on a nonbusiness day, and for all requests other than by telephone, the redemption proceeds generally will leave Vanguard by the close of business on the next business day.

•Note on timing of wire redemptions from all other funds: For requests received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the redemption proceeds generally will leave Vanguard by the close of business on the next business day. For requests received by Vanguard on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the redemption proceeds generally will leave Vanguard by the close of business on the second business day after Vanguard receives the request.

For redemptions by electronic bank transfer: If the redemption request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the same day. If the redemption request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the next business day.

31

If your redemption request is not accurate and complete, it may be rejected. If we are unable to send your redemption proceeds by wire or electronic bank transfer because the receiving institution rejects the transfer, Vanguard will make additional efforts to complete your transaction. If Vanguard is still unable to complete the transaction, we may send the proceeds of the redemption to you by check, generally payable to all registered account owners, or use your proceeds to purchase new shares of the fund from which you sold shares for the purpose of the wire or electronic bank transfer transaction. See Other Rules You Should Know—Good Order.

If your redemption request is received in good order, we typically expect that redemption proceeds will be paid by the Fund within one business day of the trade date; however, in certain circumstances, investors may experience a longer settlement period at the time of the transaction. For further information, see "Potentially disruptive redemptions" and "Emergency circumstances."

For further information about redemption transactions, consult our website at vanguard.com or see Contacting Vanguard.

Other Redemption Rules You Should Know

Documentation for certain accounts. Special documentation may be required to redeem from certain types of accounts, such as trust, corporate, nonprofit, or retirement accounts. Please call us before attempting to redeem from these types of accounts.

Potentially disruptive redemptions. Vanguard reserves the right to pay all or part of a redemption in kind—that is, in the form of securities—if we reasonably believe that a cash redemption would negatively affect the fund's operation or performance or that the shareholder may be engaged in market-timing or frequent trading. Under these circumstances, Vanguard also reserves the right to delay payment of the redemption proceeds for up to seven calendar days. By calling us before you attempt to redeem a large dollar amount, you may avoid in-kind or delayed payment of your redemption. Please see Frequent-Trading Limitations for information about Vanguard's policies to limit frequent trading.

Recently purchased shares. Although you can redeem shares at any time, proceeds may not be made available to you until the fund collects payment for your purchase. This may take up to seven calendar days for shares purchased by check or by electronic bank transfer. If you have written a check on a fund with checkwriting privileges, that check may be rejected if your fund account does not have a sufficient available balance.

Address change. If you change your address online or by telephone, there may be up to a 14-day restriction on your ability to request check redemptions online and by telephone. You can request a redemption in writing (using a form available online) at

32

any time. Confirmations of address changes are sent to both the old and new addresses.

Payment to a different person or address. At your request, we can make your redemption check payable, or wire your redemption proceeds, to a different person or send it to a different address. However, this generally requires the written consent of all registered account owners and may require additional documentation, such as a signature guarantee or a notarized signature. You may obtain a signature guarantee from some commercial or savings banks, credit unions, trust companies, or member firms of a U.S. stock exchange.

No cancellations. Vanguard will not accept your request to cancel any redemption request once processing has begun. Please be careful when placing a redemption request.

Emergency circumstances. Vanguard funds can postpone payment of redemption proceeds for up to seven calendar days. In addition, Vanguard funds can suspend redemptions and/or postpone payments of redemption proceeds beyond seven calendar days at times when the NYSE is closed or during emergency circumstances, as determined by the SEC.

Exchanging Shares

An exchange occurs when you use the proceeds from the redemption of shares of one Vanguard fund to simultaneously purchase shares of a different Vanguard fund. You can make exchange requests online (if you are registered for online access), by telephone, or by mail. See Purchasing Shares and Redeeming Shares.

If the NYSE is open for regular trading (generally until 4 p.m., Eastern time, on a business day) at the time an exchange request is received in good order, the trade date generally will be the same day. See Other Rules You Should Know—Good Order for additional information on all transaction requests.

Vanguard will not accept your request to cancel any exchange request once processing has begun. Please be careful when placing an exchange request.

Call Vanguard before attempting to exchange a large dollar amount. By calling us before you attempt to exchange a large dollar amount, you may avoid delayed or rejected transactions.

Please note that Vanguard reserves the right, without notice, to revise or terminate the exchange privilege, limit the amount of any exchange, or reject an exchange, at any time, for any reason. See Frequent-Trading Limitations for additional restrictions on exchanges.

33

Frequent-Trading Limitations

Because excessive transactions can disrupt management of a fund and increase the fund's costs for all shareholders, the board of trustees of each Vanguard fund places certain limits on frequent trading in the funds. Each Vanguard fund (other than money market funds and short-term bond funds, but including Vanguard Short-Term Inflation- Protected Securities Index Fund) limits an investor's purchases or exchanges into a fund account for 30 calendar days after the investor has redeemed or exchanged out of that fund account. ETF Shares are not subject to these frequent-trading limits.

For Vanguard Retirement Investment Program pooled plans, the limitations apply to exchanges made online or by telephone.

These frequent-trading limitations do not apply to the following:

•Purchases of shares with reinvested dividend or capital gains distributions.

•Transactions through Vanguard's Automatic Investment Plan, Automatic Exchange Service, Direct Deposit Service, Automatic Withdrawal Plan, Required Minimum Distribution Service, and Vanguard Small Business Online®.

•Discretionary transactions through Vanguard Personal Advisor Services®, Vanguard Institutional Advisory Services®, and Vanguard Digital AdvisorTM.

•Redemptions of shares to pay fund or account fees.

•Redemptions of shares to remove excess shareholder contributions to certain types of retirement accounts (including, but not limited to, IRAs and Vanguard Individual 401(k) Plans).

•Transfers and reregistrations of shares within the same fund.

•Purchases of shares by asset transfer or direct rollover.

•Conversions of shares from one share class to another in the same fund.

•Checkwriting redemptions.

•Section 529 college savings plans.

•Certain approved institutional portfolios and asset allocation programs, as well as trades made by funds or trusts managed by Vanguard or its affiliates that invest in other Vanguard funds. (Please note that shareholders of Vanguard's funds of funds are subject to the limitations.)

For participants in employer-sponsored defined contribution plans,* the frequent- trading limitations do not apply to:

•Purchases of shares with participant payroll or employer contributions or loan repayments.

•Purchases of shares with reinvested dividend or capital gains distributions.

•Distributions, loans, and in-service withdrawals from a plan.

34

•Redemptions of shares as part of a plan termination or at the direction of the plan.

•Transactions executed through the Vanguard Managed Account Program.

•Redemptions of shares to pay fund or account fees.

•Share or asset transfers or rollovers.

•Reregistrations of shares.

•Conversions of shares from one share class to another in the same fund.

•Exchange requests submitted by written request to Vanguard. (Exchange requests submitted by fax, if otherwise permitted, are subject to the limitations.)

*The following Vanguard fund accounts are subject to the frequent-trading limitations: SEP-IRAs, SIMPLE IRAs, certain Individual 403(b)(7) Custodial Accounts, and Vanguard Individual 401(k) Plans.

Accounts Held by Institutions (Other Than Defined Contribution Plans)

Vanguard will systematically monitor for frequent trading in institutional clients' accounts. If we detect suspicious trading activity, we will investigate and take appropriate action, which may include applying to a client's accounts the 30-day policy previously described, prohibiting a client's purchases of fund shares, and/or revoking the client's exchange privilege.

Accounts Held by Intermediaries

When intermediaries establish accounts in Vanguard funds for the benefit of their clients, we cannot always monitor the trading activity of the individual clients. However, we review trading activity at the intermediary (omnibus) level, and if we detect suspicious activity, we will investigate and take appropriate action. If necessary, Vanguard may prohibit additional purchases of fund shares by an intermediary, including for the benefit of certain of the intermediary's clients. Intermediaries also may monitor their clients' trading activities with respect to Vanguard funds.

For those Vanguard funds that charge purchase and/or redemption fees, intermediaries will be asked to assess these fees on client accounts and remit these fees to the funds. The application of purchase and redemption fees and frequent- trading limitations may vary among intermediaries. There are no assurances that Vanguard will successfully identify all intermediaries or that intermediaries will properly assess purchase and redemption fees or administer frequent-trading limitations. If you invest with Vanguard through an intermediary, please read that firm's materials carefully to learn of any other rules or fees that may apply.

Investing With Vanguard Through Other Firms

You may purchase or sell shares of most Vanguard funds through a financial intermediary, such as a bank, a broker, or an investment advisor. Please consult your financial intermediary to determine which, if any, shares are available through that firm and to learn about other rules that may apply. Your financial intermediary can provide you with account information and any required tax forms. You may be required to pay a commission on purchases of mutual fund shares made through a financial intermediary.

Please see Frequent-Trading Limitations—Accounts Held by Intermediaries for information about the assessment of any purchase or redemption fees and the monitoring of frequent trading for accounts held by intermediaries.

Account Service Fee

Vanguard may charge a $20 account service fee on fund accounts that have a balance below $10,000 for any reason, including market fluctuation. The account service fee applies to both retirement and nonretirement fund accounts and may be assessed on fund accounts in all Vanguard funds, regardless of the account minimum. The fee, which will be collected by redeeming fund shares in the amount of $20, will be deducted from fund accounts subject to the fee once per calendar year.

If you elect to receive your statements and other materials electronically (i.e., by e-delivery), the account service fee will not be charged, so long as your election remains in effect. You can make your e-delivery election on vanguard.com.

Beginning on January 1, 2021, you may elect to receive paper copies of shareholder reports free of charge as noted on the cover of this prospectus.

38

Certain account types have alternative fee structures, including SIMPLE IRAs, Vanguard Retirement Investment Program pooled plans, and Vanguard Individual 401(k) Plans.

Low-Balance Accounts

The Fund reserves the right to liquidate a fund account whose balance falls below the account minimum for any reason, including market fluctuation. This liquidation policy applies to nonretirement fund accounts and accounts that are held through intermediaries. Any such liquidation will be preceded by written notice to the investor.

Right to Change Policies

In addition to the rights expressly stated elsewhere in this prospectus, Vanguard reserves the right, without notice, to (1) alter, add, or discontinue any conditions of purchase (including eligibility requirements), redemption, exchange, service, or privilege at any time and (2) alter, impose, discontinue, or waive any purchase fee, redemption fee, account service fee, or other fee charged to a shareholder or a group of shareholders. Changes may affect any or all investors. These actions will be taken when, at the sole discretion of Vanguard management, Vanguard believes they are in the best interest of a fund.

Account Restrictions

Vanguard reserves the right to: (1) redeem all or a portion of a fund/account to meet a legal obligation, including tax withholding, tax lien, garnishment order, or other obligation imposed on your account by a court or government agency; (2) redeem shares, close an account, or suspend account privileges, features, or options in the case of threatening conduct or activity; (3) redeem shares, close an account, or suspend account privileges, features, or options if Vanguard believes or suspects that not doing so could result in a suspicious, fraudulent, or illegal transaction; (4) place restrictions on the ability to redeem any or all shares in an account if it is required to do so by a court or government agency; (5) place restrictions on the ability to redeem any or all shares in an account if Vanguard believes that doing so will prevent fraud, financial exploitation or abuse, or to protect vulnerable investors; (6) freeze any account and/or suspend account services if Vanguard has received reasonable notice of a dispute regarding the assets in an account, including notice of a dispute between the registered or beneficial account owners; and (7) freeze any account and/or suspend account services upon initial notification to Vanguard of the death of an account owner.

Consult your recordkeeper or plan administrator for more information.

If Vanguard is serving as your plan recordkeeper and if your transaction involves one or more investments with an early cut-off time for processing or another trading restriction, your entire transaction will be subject to the restriction when the trade date for your transaction is determined.

Glossary of Investment Terms

Bond. A debt security (IOU) issued by a corporation, a government, or a government agency in exchange for the money the bondholder lends it. In most instances, the issuer agrees to pay back the loan by a specific date and generally to make regular interest payments until that date.

Common Stock. A security representing ownership rights in a corporation.

Correlation. The relationship between two variables, such as the relationship between the prices of stocks and bonds. Investments that are positively correlated have prices that tend to move in the same direction at the same time, while investments that are negatively correlated have prices that tend to move in opposite directions at the same time. Investments with low correlation have prices that tend to move independently of each other.

Dividend Distributions. Payments to mutual fund shareholders of income from interest or dividends generated by a fund's investments.

Expense Ratio. A fund's total annual operating expenses expressed as a percentage of the fund's average net assets. The expense ratio includes management and administrative expenses, but it does not include the transaction costs of buying and selling portfolio securities.

Investment-Grade Bond. A debt security whose credit quality is considered by independent bond rating agencies, or through independent analysis conducted by a fund's advisor, to be sufficient to ensure timely payment of principal and interest under current economic circumstances. Debt securities rated in one of the four highest rating categories are considered investment-grade. Other debt securities may be considered by an advisor to be investment-grade.

Joint Committed Credit Facility. The Fund may participate, along with other funds managed by Vanguard, in a committed credit facility provided by a syndicate of lenders pursuant to a credit agreement that may be renewed annually; each Vanguard fund is individually liable for its borrowings, if any, under the credit facility. The amount and terms of the committed credit facility are subject to approval by the Fund's board of trustees and renegotiation with the lender syndicate on an annual basis. New funds, such as Vanguard Commodity Strategy, will generally be added to the agreement during the annual renewal process.

Mutual Fund. An investment company that pools the money of many people and invests it in a variety of securities in an effort to achieve a specific objective over time.

Fund Summary

Investment Objective

The Fund seeks to provide long-term capital appreciation and dividend income.

Fees and Expenses

The following table describes the fees and expenses you may pay if you buy and hold shares of the Fund.

Shareholder Fees

(Fees paid directly from your investment)

Sales Charge (Load) Imposed on Purchases	None
Purchase Fee	None
Sales Charge (Load) Imposed on Reinvested Dividends	None
Redemption Fee	None
Account Service Fee (for certain fund account balances below $10,000)	$20/year

Annual Fund Operating Expenses

(Expenses that you pay each year as a percentage of the value of your investment)

Management Fees	None
12b-1 Distribution Fee	None
Other Expenses	None
Acquired Fund Fees and Expenses	0.35%
Total Annual Fund Operating Expenses	0.35%

1

Example

The following example is intended to help you compare the cost of investing in the Fund (based on the fees and expenses of the acquired funds) with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you were to invest $10,000 in the Fund's shares. This example assumes that the Fund provides a return of 5% each year and that total annual fund operating expenses of the Fund and its underlying funds remain as stated in the preceding table. You would incur these hypothetical expenses whether or not you were to redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years	5 Years	10 Years
$36	$113	$197	$443

Portfolio Turnover

The Fund may pay transaction costs, such as purchase fees, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 9% of the average value of its portfolio.

Principal Investment Strategies

As a fund of funds, the Diversified Equity Fund invests in a diversified group of other Vanguard equity mutual funds, rather than in individual securities. The underlying funds' holdings mainly consist of large-, mid-, and small-capitalization equity securities of domestic companies.

Principal Risks

An investment in the Fund could lose money over short or long periods of time. You should expect the Fund's share price and total return to fluctuate within a wide range. The Fund is subject to the following risks, which could affect the Fund's performance:

•Stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices.

•Manager risk, which is the chance that poor security selection will cause one or more of the Fund's actively managed underlying funds—and, thus, the Fund itself—to underperform relevant benchmarks or other funds with a similar investment objective.

2

•The Fund is also subject to asset allocation risk, which is the chance that the selection of underlying funds, and the allocation of a high percentage of assets to a relatively few number of underlying funds may cause the Fund to be hurt disproportionately by the poor performance of any one underlying fund or to underperform other funds with a similar investment objective.

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Annual Total Returns

The following bar chart and table are intended to help you understand the risks of investing in the Fund.

Actual after-tax returns depend on your tax situation and may differ from those shown in the preceding table. When after-tax returns are calculated, it is assumed that the shareholder was in the highest individual federal marginal income tax bracket at the time of each distribution of income or capital gains or upon redemption. State and local income taxes are not reflected in the calculations. Please note that after-tax returns are not relevant for a shareholder who holds fund shares in a tax-deferred account, such as an individual retirement account or a 401(k) plan. Also, figures captioned Return After Taxes on Distributions and Sale of Fund Shares may be higher than other figures for the same period if a capital loss occurs upon redemption and results in an assumed tax deduction for the shareholder.

More on the Fund

This prospectus describes the principal risks you would face as a Fund shareholder. It is important to keep in mind one of the main principles of investing: generally, the higher the risk of losing money, the higher the potential reward. The reverse, also, is generally true: the lower the risk, the lower the potential reward. As you consider an investment in any mutual fund, you should take into account your personal tolerance

for fluctuations in the securities markets. Look for this symbol throughout the prospectus. It is used to mark detailed information about the more significant risks that you would confront as a Fund shareholder. To highlight terms and concepts important to mutual fund investors, we have provided Plain Talk® explanations along the way. Reading the prospectus will help you decide whether the Fund is the right investment for you. We suggest that you keep this prospectus for future reference.

Plain Talk About Costs of Investing

Costs are an important consideration in choosing a mutual fund. That is because you, as a shareholder, pay a proportionate share of the costs of operating a fund and any transaction costs incurred when the fund buys or sells securities. These costs can erode a substantial portion of the gross income or the capital appreciation a fund achieves. Even seemingly small differences in expenses can, over time, have a dramatic effect on a fund's performance.

The following sections explain the principal investment strategies and policies that the Fund uses in pursuit of its objective. The Fund's board of trustees, which oversees the Fund's management, may change investment strategies or policies in the interest of shareholders without a shareholder vote, unless those strategies or policies are designated as fundamental. Note that the Fund's investment objective is not fundamental and may be changed without a shareholder vote. As a fund of funds, the Diversified Equity Fund achieves its investment objective by investing in other Vanguard mutual funds. Through its investments in underlying funds, the Diversified Equity Fund indirectly owns a diversified portfolio of stocks.

Market Exposure

Through the underlying Vanguard funds, the Diversified Equity Fund indirectly invests its assets in equity securities. These investments are designed to provide long-term capital appreciation and some income. The underlying equity funds are described later in this section under "Security Selection." Under normal circumstances, the Fund will invest at least 80% of its assets in equity securities. The Fund's policy of investing at least 80% of its assets in equity securities may only be changed upon 60 days' notice to shareholders.

6

The Fund is subject to asset allocation risk, which is the chance that the selection of underlying funds, and the allocation of a high percentage of assets to a relatively few number of underlying funds may cause the Fund to be hurt disproportionately by the poor performance of any one underlying fund or to underperform other funds with a similar investment objective.

Stocks of publicly traded companies are often classified according to market capitalization, which is the market value of a company's outstanding shares. These classifications typically include small-cap, mid-cap, and large-cap. It is important to understand that there are no "official" definitions of small-, mid-, and large-cap, even among Vanguard fund advisors, and that market capitalization ranges can change over time. The asset-weighted median market capitalization of the Fund's indirect stock holdings as of October 31, 2019, was $48 billion.

By owning shares of the underlying funds, the Fund indirectly owns a diversified mixture of common stocks. Although its indirect stock holdings are predominantly mid- and large- cap, the Fund consists of stocks across the capitalization spectrum, including small-cap. Historically, small- and mid-cap stocks have been more volatile in price than large-cap stocks. This volatility is the result of several factors, including the fact that smaller companies often have fewer customers and financial resources than larger firms. These characteristics can make small and mid-size companies more sensitive to economic conditions, leading to less certain growth and dividend prospects.

The Fund is subject to stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices.

Security Selection

The Fund seeks to achieve its objective by investing in a combination of other mutual funds rather than in individual securities.

The underlying Vanguard funds are managed according to traditional methods of active investment management. This means that securities are bought and sold according to the advisors' judgments about companies and their financial prospects.

The Diversified Equity Fund invests in the following funds, in approximately the percentages indicated. As of the date of this prospectus, the Fund held Investor Shares of each underlying Vanguard fund. Share class changes may be made without prior notice to shareholders.

•Vanguard U.S. Growth Fund (30%)

•Vanguard Growth and Income Fund (20%)

•Vanguard Windsor II™ Fund (15%)

7

•Vanguard Windsor™ Fund (15%)

•Vanguard Explorer™ Fund (10%)

•Vanguard Mid-Cap Growth Fund (5%)

•Vanguard Capital Value Fund (5%)

Vanguard Growth and Income Fund, made up of both value- and growth-oriented stocks that are mainly large-cap, is included primarily for its potential for a total return greater than that of the S&P 500 Index.

•Vanguard Growth and Income Fund uses quantitative approaches to select a broadly diversified group of stocks that, as a whole, have investment characteristics similar to those of the S&P 500 Index but are expected to provide a higher total return than that of the Index.

Vanguard Windsor Fund, Vanguard Windsor II Fund, and Vanguard Capital Value Fund are value-oriented stock funds. These funds are included primarily for their potential for long- term capital appreciation. Vanguard Windsor Fund and Vanguard Windsor II Fund have a secondary objective of providing some dividend income.

•Vanguard Windsor Fund and Vanguard Windsor II Fund invest in mid- and large-cap companies, and Vanguard Capital Value Fund invests in companies across the capitalization spectrum. These funds invest in companies whose stocks are considered undervalued by the advisors. These stocks typically have below-average prices in relation to measures such as earnings and book value.

Vanguard Explorer Fund, Vanguard U.S. Growth Fund, and Vanguard Mid-Cap Growth Fund are growth-oriented stock funds. These funds are included primarily to provide long-term capital appreciation. They work in different ways to achieve this goal.

•Vanguard Explorer Fund invests mainly in the stocks of small and mid-size companies. These companies tend to be unseasoned but are considered by the fund's advisors to have superior growth potential. These companies often provide little or no dividend income.

•Vanguard U.S. Growth Fund invests mainly in large-cap stocks of U.S. companies considered to have above-average earnings growth potential and reasonable stock prices in comparison with expected earnings.

•Vanguard Mid-Cap Growth Fund invests mainly in the stocks of mid-size companies. In selecting stocks, the fund's advisors choose companies considered to have the best prospects for future growth.

The Fund is subject to manager risk, which is the chance that poor security selection will cause one or more of the Fund's actively managed underlying funds—and, thus, the Fund itself—to underperform relevant benchmarks or other funds with a similar investment objective.

Plain Talk About Growth Funds and Value Funds

Growth investing and value investing are two styles employed by stock-fund managers. Growth funds generally invest in stocks of companies believed to have above-average potential for growth in revenue, earnings, cash flow, or other similar criteria. These stocks typically have low dividend yields, if any, and above- average prices in relation to measures such as earnings and book value. Value funds typically invest in stocks whose prices are below average in relation to those measures; these stocks often have above-average dividend yields. Value stocks also may remain undervalued by the market for long periods of time. Growth and value stocks have historically produced similar long-term returns, though each category has periods when it outperforms the other.

Other Investment Policies and Risks

Through its investment in the underlying funds, Vanguard Diversified Equity Fund is proportionately exposed to certain investment style risks, each of which is described in detail in the underlying funds' prospectuses. For example, through its investment in Vanguard Explorer Fund and Vanguard Mid-Cap Growth Fund, the Fund is subject to the risk that small-cap growth stocks and mid-cap growth stocks, respectively, will trail returns from the overall stock market. Historically, small- and mid-cap stocks have been more volatile in price than the large-cap stocks that dominate the overall stock market, and they often perform quite differently. Because the Diversified Equity Fund indirectly invests in growth and value stocks, and across all capitalization ranges, the Fund in the aggregate is not subject to any particular primary investment style risk.

To the extent that the underlying funds own foreign securities, the Fund is subject to country risk and currency risk. Country risk is the chance that world events—such as political upheaval, financial troubles, or natural disasters—will adversely affect the value of securities issued by companies in foreign countries. In addition, the prices of foreign stocks and the prices of U.S. stocks have, at times, moved in opposite directions. Currency risk is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates.

Each underlying fund may invest, to a limited extent, in derivatives. Generally speaking, a derivative is a financial contract whose value is based on the value of a financial asset (such as a stock, a bond, or a currency), a physical asset (such as gold, oil, or wheat), a market index, or a reference rate. Investments in derivatives may subject the funds to risks different from, and possibly greater than, those of investments directly in the underlying securities or assets. The underlying funds will not use derivatives for speculation or for the purpose of leveraging (magnifying) investment returns.

9

Cash Management

The Fund's daily cash balance may be invested in Vanguard Market Liquidity Fund and/or Vanguard Municipal Cash Management Fund (each, a CMT Fund), which are low-cost money market funds. When investing in a CMT Fund, the Fund bears its proportionate share of the expenses of the CMT Fund in which it invests. Vanguard receives no additional revenue from Fund assets invested in a CMT Fund.

Methods Used to Meet Redemption Requests

Under normal circumstances, the Fund typically expects to meet redemptions with positive cash flows. When this is not an option, the Fund seeks to maintain its risk exposure by selling a cross section of the Fund's holdings to meet redemptions, while also factoring in transaction costs. Additionally, the Fund may work with larger clients to implement their redemptions in a manner that is least disruptive to the portfolio; see "Potentially disruptive redemptions" under Redeeming Shares in the Investing With Vanguard section.

Under certain circumstances, including under stressed market conditions, there are additional tools that the Fund may use in order to meet redemptions, including advancing the settlement of market trades with counterparties to match investor redemption payments or delaying settlement of an investor's transaction to match trade settlement within regulatory requirements. The Fund may also suspend payment of redemption proceeds for up to seven days; see "Emergency circumstances" under Redeeming Shares in the Investing With Vanguard section. Additionally under these unusual circumstances, the Fund may borrow money (subject to certain regulatory conditions and if available under board-approved procedures) through an interfund lending facility or through a bank line-of-credit, including a joint committed credit facility, in order to meet redemption requests.

Temporary Investment Measures

Each underlying fund may take temporary defensive positions that are inconsistent with its normal investment policies and strategies—for instance, by allocating substantial assets to cash equivalent investments or other less volatile instruments— in response to adverse or unusual market, economic, political, or other conditions. In doing so, the underlying fund may succeed in avoiding losses but may otherwise fail to achieve its investment objective, which in turn may prevent the Diversified Equity Fund from achieving its investment objective.

Frequent Trading or Market-Timing

Background. Some investors try to profit from strategies involving frequent trading of mutual fund shares, such as market-timing. For funds holding foreign securities, investors may try to take advantage of an anticipated difference between the price of the fund's shares and price movements in overseas markets, a practice also known as

10

time-zone arbitrage. Investors also may try to engage in frequent trading of funds holding investments such as small-cap stocks and high-yield bonds. As money is shifted into and out of a fund by a shareholder engaging in frequent trading, the fund incurs costs for buying and selling securities, resulting in increased brokerage and administrative costs. These costs are borne by all fund shareholders, including the long-term investors who do not generate the costs. In addition, frequent trading may interfere with an advisor's ability to efficiently manage the fund.

Policies to address frequent trading. The Vanguard funds (other than money market funds and short-term bond funds, but including Vanguard Short-Term Inflation- Protected Securities Index Fund) do not knowingly accommodate frequent trading. The board of trustees of each Vanguard fund (other than money market funds and short- term bond funds, but including Vanguard Short-Term Inflation-Protected Securities Index Fund) has adopted policies and procedures reasonably designed to detect and discourage frequent trading and, in some cases, to compensate the fund for the costs associated with it. These policies and procedures do not apply to ETF Shares because frequent trading in ETF Shares generally does not disrupt portfolio management or otherwise harm fund shareholders. Although there is no assurance that Vanguard will be able to detect or prevent frequent trading or market-timing in all circumstances, the following policies have been adopted to address these issues:

•Each Vanguard fund reserves the right to reject any purchase request—including exchanges from other Vanguard funds—without notice and regardless of size. For example, a purchase request could be rejected because the investor has a history of frequent trading or if Vanguard determines that such purchase may negatively affect a fund's operation or performance.

•Each Vanguard fund (other than money market funds and short-term bond funds, but including Vanguard Short-Term Inflation-Protected Securities Index Fund) generally prohibits, except as otherwise noted in the Investing With Vanguard section, an investor's purchases or exchanges into a fund account for 30 calendar days after the investor has redeemed or exchanged out of that fund account.

•Certain Vanguard funds charge shareholders purchase and/or redemption fees on transactions.

See the Investing With Vanguard section of this prospectus for further details on Vanguard's transaction policies.

Each Vanguard fund (other than retail and government money market funds), in determining its net asset value, will use fair-value pricing when appropriate, as described in the Share Price section. Fair-value pricing may reduce or eliminate the profitability of certain frequent-trading strategies.

Do not invest with Vanguard if you are a market-timer.

11

Turnover Rate

Although the Fund generally seeks to invest for the long term, it may sell shares of the underlying funds regardless of how long they have been held. The Financial Highlights section of this prospectus shows historical turnover rates for the Fund. A turnover rate of 100%, for example, would mean that the Fund had sold and replaced shares of the underlying funds valued at 100% of its net assets within a one-year period. In general, the greater the turnover rate, the greater the impact transaction costs will have on a fund's return. Also, funds with high turnover rates may be more likely to generate capital gains, including short-term capital gains, that must be distributed to shareholders and will be taxable to shareholders investing through a taxable account.

The Fund and Vanguard

The Fund is a member of The Vanguard Group, a family of over 200 funds. All of the funds that are members of The Vanguard Group (other than funds of funds) share in the expenses associated with administrative services and business operations, such as personnel, office space, and equipment.

Vanguard Marketing Corporation provides marketing services to the funds. Although fund shareholders do not pay sales commissions or 12b-1 distribution fees, each fund (other than a fund of funds) or each share class of a fund (in the case of a fund with multiple share classes) pays its allocated share of the Vanguard funds' marketing costs.

According to an agreement applicable to Vanguard Diversified Equity Fund and Vanguard, the Fund's direct expenses may be offset by (1) the Fund's contributions to the costs of operating the underlying Vanguard funds in which the Fund invests and (2) certain savings in administrative and marketing costs that Vanguard expects to derive from the Fund's operation.

Accordingly, all expenses for services provided by Vanguard to the Fund and all other expenses incurred by the Fund are expected to be borne by the underlying funds. The Fund's shareholders bear the fees and expenses associated with the Fund's investment in the underlying funds.

Plain Talk About Vanguard's Unique Corporate Structure

The Vanguard Group is owned jointly by the funds it oversees and thus indirectly by the shareholders in those funds. Most other mutual funds are operated by management companies that are owned by third parties—either public or private stockholders—and not by the funds they serve.

Investment Advisor

The Vanguard Group, Inc., P.O. Box 2600, Valley Forge, PA 19482, which began operations in 1975, serves as advisor to the Fund through its Equity Index Group. Vanguard also serves as investment advisor for each of the underlying funds. As of October 31, 2019, Vanguard served as advisor for approximately $4.7 trillion in assets. Vanguard provides investment advisory services to the Fund pursuant to the Funds' Service Agreement and subject to the supervision and oversight of the trustees and officers of the Fund.

The underlying Vanguard funds employ multiple advisors, none of which are paid a management fee for performing investment management services for Vanguard Diversified Equity Fund. However, the advisors receive management fees for managing the underlying Vanguard funds. For additional information on the investment advisors, please refer to each underlying fund's prospectus.

Under the terms of an SEC exemption, the Fund's board of trustees may, without prior approval from shareholders, change the terms of an advisory agreement with a third- party investment advisor or hire a new third-party investment advisor—either as a replacement for an existing advisor or as an additional advisor. Any significant change in the Fund's advisory arrangements will be communicated to shareholders in writing. As the Fund's sponsor and overall manager, Vanguard may provide investment advisory services to the Fund at any time. Vanguard may also recommend to the board of trustees that an advisor be hired, terminated, or replaced or that the terms of an existing advisory agreement be revised. The Fund has filed an application seeking a similar SEC exemption with respect to investment advisors that are wholly owned subsidiaries of Vanguard. If the exemption is granted, the Fund may rely on the new SEC relief.

For a discussion of why the board of trustees approved the Fund's investment advisory arrangement, see the most recent semiannual report to shareholders covering the fiscal period ended April 30.

The managers primarily responsible for the day-to-day management of the Fund are:

William Coleman, CFA, Portfolio Manager at Vanguard. He has worked in investment management since joining Vanguard in 2006 and has co-managed the Fund since 2013. Education: B.S., King's College; M.S., Saint Joseph's University.

Walter Nejman, Portfolio Manager at Vanguard. He has been with Vanguard since 2005, has worked in investment management since 2008, and has co-managed the Fund since 2013. Education: B.A., Arcadia University; M.B.A., Villanova University.

The Fund's Statement of Additional Information provides information about each portfolio manager's compensation, other accounts under management, and ownership of shares of the Fund.

Dividends, Capital Gains, and Taxes

Fund Distributions

The Fund distributes to shareholders virtually all of its net income as well as any net short-term or long-term capital gains realized from the sale of its holdings or received as capital gains distributions from the underlying funds. Income and capital gains distributions, if any, generally occur annually in December. In addition, the Fund may occasionally make a supplemental distribution at some other time during the year.

You can receive distributions of income or capital gains in cash, or you can have them automatically reinvested in more shares of the Fund. However, if you are investing through an employer-sponsored retirement or savings plan, your distributions will be automatically reinvested in additional Fund shares.

Basic Tax Points

Investors in taxable accounts should be aware of the following basic federal income tax points:

•Distributions are taxable to you whether or not you reinvest these amounts in additional Fund shares.

•Distributions declared in December—if paid to you by the end of January—are taxable as if received in December.

•Any dividend distribution or short-term capital gains distribution that you receive is taxable to you as ordinary income. If you are an individual and meet certain holding- period requirements with respect to your Fund shares, you may be eligible for reduced tax rates on "qualified dividend income,"if any, distributed by the Fund.

•Any distribution of net long-term capital gains is taxable to you as long-term capital gains, no matter how long you have owned shares in the Fund.

•Capital gains distributions may vary considerably from year to year as a result of the Fund's normal investment activities and cash flows.

•A sale or exchange of Fund shares is a taxable event. This means that you may have a capital gain to report as income, or a capital loss to report as a deduction, when you complete your tax return.

•Vanguard (or your intermediary) will send you a statement each year showing the tax status of all of your distributions.

Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to a 3.8% Medicare contribution tax on "net investment income." Net investment income takes into account distributions paid by the Fund and capital gains from any sale or exchange of Fund shares.

14

Dividend distributions and capital gains distributions that you receive, as well as your gains or losses from any sale or exchange of Fund shares, may be subject to state and local income taxes.

This prospectus provides general tax information only. If you are investing through a tax-advantaged account, such as an IRA or an employer-sponsored retirement or savings plan, special tax rules apply. Please consult your tax advisor for detailed information about any tax consequences for you.

Plain Talk About Buying a Dividend

Unless you are a tax-exempt investor or investing through a tax-advantaged account (such as an IRA or an employer-sponsored retirement or savings plan), you should consider avoiding a purchase of fund shares shortly before the fund makes a distribution, because doing so can cost you money in taxes. This is known as "buying a dividend." For example: On December 15, you invest $5,000, buying 250 shares for $20 each. If the fund pays a distribution of $1 per share on December 16, its share price will drop to $19 (not counting market change). You still have only $5,000 (250 shares x $19 = $4,750 in share value, plus 250 shares x $1 = $250 in distributions), but you owe tax on the $250 distribution you received—even if you reinvest it in more shares. To avoid buying a dividend, check a fund's distribution schedule before you invest.

General Information

Backup withholding. By law, Vanguard must withhold 24% of any taxable distributions or redemptions from your account if you do not:

•Provide your correct taxpayer identification number.

•Certify that the taxpayer identification number is correct.

•Confirm that you are not subject to backup withholding.

Similarly, Vanguard (or your intermediary) must withhold taxes from your account if the IRS instructs us to do so.

Foreign investors. Vanguard funds offered for sale in the United States (Vanguard U.S. funds), including the Fund offered in this prospectus, are not widely available outside the United States. Non-U.S. investors should be aware that U.S. withholding and estate taxes and certain U.S. tax reporting requirements may apply to any investments in Vanguard U.S. funds. Foreign investors should visit the non-U.S. investors page on our website at vanguard.com for information on Vanguard's non-U.S. products.

Invalid addresses. If a dividend distribution or capital gains distribution check mailed to your address of record is returned as undeliverable, Vanguard will automatically reinvest the distribution and all future distributions until you provide us with a valid

15

mailing address. Reinvestments will receive the net asset value calculated on the date of the reinvestment.

Share Price

Share price, also known as net asset value (NAV), is calculated as of the close of regular trading on the New York Stock Exchange (NYSE), generally 4 p.m., Eastern time, on each day that the NYSE is open for business (a business day). In the rare event the NYSE experiences unanticipated disruptions and is unavailable at the close of the trading day, the Fund reserves the right to treat such day as a business day and calculate NAVs as of the close of regular trading on the Nasdaq (or another alternate exchange if the Nasdaq is unavailable, as determined at Vanguard's discretion), generally 4 p.m., Eastern time. The NAV per share is computed by dividing the total assets, minus liabilities, of the Fund by the number of Fund shares outstanding. On U.S. holidays or other days when the NYSE is closed, the NAV is not calculated, and the Fund does not sell or redeem shares. The underlying Vanguard funds in which the Fund invests also do not calculate their NAV on days when the NYSE is closed, but the value of their assets may be affected to the extent that they hold securities that change in value on those days (such as foreign securities that trade on foreign markets that are open).

The Fund's NAV is calculated based upon the values of the underlying mutual funds in which the Fund invests. The values of any mutual fund shares, including institutional money market fund shares, held by a fund are based on the NAVs of the shares. The values of any ETF shares held by a fund are based on the market value of the shares. The prospectuses for the underlying funds explain the circumstances under which those funds will use fair-value pricing and the effects of doing so.

Vanguard fund share prices are published daily on our website at vanguard.com/prices.

Financial Highlights

Financial highlights information is intended to help you understand a fund's performance for the past five years (or, if shorter, its period of operations). Certain information reflects financial results for a single fund share. Total return represents the rate that an investor would have earned or lost each period on an investment in a fund or share class (assuming reinvestment of all distributions). This information has been obtained from the financial statements audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, whose report, along with fund financial statements, is included in a fund's most recent annual report to shareholders. You may obtain a free copy of a fund's latest annual or semiannual report, which is available upon request.

Investing With Vanguard

This section of the prospectus explains the basics of doing business with Vanguard. Vanguard fund shares can be held directly with Vanguard or indirectly through an intermediary, such as a bank, a broker, or an investment advisor. If you hold Vanguard fund shares directly with Vanguard, you should carefully read each topic within this section that pertains to your relationship with Vanguard. If you hold Vanguard fund shares indirectly through an intermediary (including shares held in a brokerage account through Vanguard Brokerage Services®), please see Investing With Vanguard Through Other Firms, and also refer to your account agreement with the intermediary for information about transacting in that account. If you hold Vanguard fund shares through an employer-sponsored retirement or savings plan, please see Employer-Sponsored Plans. Vanguard reserves the right to change the following policies without notice. Please call or check online for current information. See Contacting Vanguard.

For Vanguard fund shares held directly with Vanguard, each fund you hold in an account is a separate "fund account." For example, if you hold three funds in a nonretirement account titled in your own name, two funds in a nonretirement account titled jointly with your spouse, and one fund in an individual retirement account, you have six fund accounts—and this is true even if you hold the same fund in multiple accounts. Note that each reference to "you" in this prospectus applies to any one or more registered account owners or persons authorized to transact on your account.

How to Initiate a Purchase Request

Be sure to check Exchanging Shares, Frequent-Trading Limitations, and Other Rules You Should Know before placing your purchase request.

18

Online. You may open certain types of accounts, request a purchase of shares, and request an exchange through our website or our mobile application if you are registered for online access.

By telephone. You may call Vanguard to begin the account registration process or request that the account-opening forms be sent to you. You may also call Vanguard to request a purchase of shares in your account or to request an exchange. See Contacting Vanguard.

By mail. You may send Vanguard your account registration form and check to open a new fund account. To add to an existing fund account, you may send your check with an Invest-by-Mail form (from a transaction confirmation or your account statement) or with a deposit slip (available online).

How to Pay for a Purchase

By electronic bank transfer. You may purchase shares of a Vanguard fund through an electronic transfer of money from a bank account. To establish the electronic bank transfer service on an account, you must designate the bank account online, complete a form, or fill out the appropriate section of your account registration form. After the service is set up on your account, you can purchase shares by electronic bank transfer on a regular schedule (Automatic Investment Plan) or upon request. Your purchase request can be initiated online (if you are registered for online access), by telephone, or by mail.

By wire. Wiring instructions vary for different types of purchases. Please call Vanguard for instructions and policies on purchasing shares by wire. See Contacting Vanguard.

By check. You may make initial or additional purchases to your fund account by sending a check with a deposit slip or by utilizing our mobile application if you are registered for online access. Also see How to Initiate a Purchase Request. Make your check payable to Vanguard and include the appropriate fund number (Vanguard—608).

By exchange. You may purchase shares of a Vanguard fund using the proceeds from the simultaneous redemption of shares of another Vanguard fund. You may initiate an exchange online (if you are registered for online access), by telephone, or by mail with an exchange form. See Exchanging Shares.

Trade Date

The trade date for any purchase request received in good order will depend on the day and time Vanguard receives your request, the manner in which you are paying, and the type of fund you are purchasing. Your purchase will be executed using the NAV as calculated on the trade date. See Share Price.

19

For purchases by check into all funds other than money market funds and for purchases by exchange, wire, or electronic bank transfer into all funds: If the purchase request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date for the purchase will be the same day. If the purchase request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date for the purchase will be the next business day.

For purchases by check into money market funds: If the purchase request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date for the purchase will be the next business day. If the purchase request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date for the purchase will be the second business day following the day Vanguard receives the purchase request. Because money market instruments must be purchased with federal funds and it takes a money market mutual fund one business day to convert check proceeds into federal funds, the trade date for the purchase will be one business day later than for other funds.

If your purchase request is not accurate and complete, it may be rejected. See Other Rules You Should Know—Good Order.

For further information about purchase transactions, consult our website at vanguard.com or see Contacting Vanguard.

Other Purchase Rules You Should Know

Check purchases. All purchase checks must be written in U.S. dollars, be drawn on a U.S. bank, and be accompanied by good order instructions. Vanguard does not accept cash, traveler's checks, starter checks, or money orders. In addition, Vanguard may refuse checks that are not made payable to Vanguard.

New accounts. We are required by law to obtain from you certain personal information that we will use to verify your identity. If you do not provide the information, we may not be able to open your account. If we are unable to verify your identity, Vanguard reserves the right, without notice, to close your account or take such other steps as we deem reasonable. Certain types of accounts may require additional documentation.

Refused or rejected purchase requests. Vanguard reserves the right to stop selling fund shares or to reject any purchase request at any time and without notice, including, but not limited to, purchases requested by exchange from another Vanguard fund. This also includes the right to reject any purchase request because the investor has a history of frequent trading or because the purchase may negatively affect a fund's operation or performance.

20

Large purchases. Call Vanguard before attempting to invest a large dollar amount.

No cancellations. Vanguard will not accept your request to cancel any purchase request once processing has begun. Please be careful when placing a purchase request.

Redeeming Shares

How to Initiate a Redemption Request

Be sure to check Exchanging Shares, Frequent-Trading Limitations, and Other Rules You Should Know before placing your redemption request.

Online. You may request a redemption of shares or request an exchange through our website or our mobile application if you are registered for online access.

By telephone. You may call Vanguard to request a redemption of shares or an exchange. See Contacting Vanguard.

By mail. You may send a form (available online) to Vanguard to redeem from a fund account or to make an exchange. See Contacting Vanguard.

How to Receive Redemption Proceeds

By electronic bank transfer. You may have the proceeds of a fund redemption sent directly to a designated bank account. To establish the electronic bank transfer service on an account, you must designate a bank account online, complete a form, or fill out the appropriate section of your account registration form. After the service is set up on your account, you can redeem shares by electronic bank transfer on a regular schedule (Automatic Withdrawal Plan) or upon request. Your redemption request can be initiated online (if you are registered for online access), by telephone, or by mail.

By wire. To receive your proceeds by wire, you may instruct Vanguard to wire your redemption proceeds ($100 minimum) to a previously designated bank account. To establish the wire redemption service, you generally must designate a bank account online, complete a form, or fill out the appropriate section of your account registration form.

Please note that Vanguard charges a $10 wire fee for outgoing wire redemptions. The fee is assessed in addition to, rather than being withheld from, redemption proceeds and is paid directly to the fund in which you invest. For example, if you redeem $100 via a wire, you will receive the full $100, and the $10 fee will be assessed to your fund account through an additional redemption of fund shares. If you redeem your entire fund account, your redemption proceeds will be reduced by the amount of the fee. The wire fee does not apply to accounts held by Flagship and Flagship Select clients; accounts held through intermediaries, including Vanguard Brokerage Services; or accounts held by institutional clients.

21

By exchange. You may have the proceeds of a Vanguard fund redemption invested directly in shares of another Vanguard fund. You may initiate an exchange online (if you are registered for online access), by telephone, or by mail. See Exchanging Shares.

By check. If you have not chosen another redemption method, Vanguard will mail you a redemption check, generally payable to all registered account owners, normally within two business days of your trade date, and generally to the address of record.

Trade Date

The trade date for any redemption request received in good order will depend on the day and time Vanguard receives your request and the manner in which you are redeeming. Your redemption will be executed using the NAV as calculated on the trade date. See Share Price.

For redemptions by check, exchange, or wire: If the redemption request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the same day. If the redemption request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the next business day.

•Note on timing of wire redemptions from money market funds: For telephone requests received by Vanguard on a business day before 10:45 a.m., Eastern time (2 p.m., Eastern time, for Vanguard Prime Money Market Fund; 12:30 p.m., Eastern time, for Vanguard Federal Money Market Fund), the redemption proceeds generally will leave Vanguard by the close of business the same day. For telephone requests received by Vanguard on a business day after those cut-off times, or on a nonbusiness day, and for all requests other than by telephone, the redemption proceeds generally will leave Vanguard by the close of business on the next business day.

•Note on timing of wire redemptions from all other funds: For requests received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the redemption proceeds generally will leave Vanguard by the close of business on the next business day. For requests received by Vanguard on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the redemption proceeds generally will leave Vanguard by the close of business on the second business day after Vanguard receives the request.

For redemptions by electronic bank transfer: If the redemption request is received by Vanguard on a business day before the close of regular trading on the NYSE (generally 4 p.m., Eastern time), the trade date will be the same day. If the redemption request is received on a business day after the close of regular trading on the NYSE, or on a nonbusiness day, the trade date will be the next business day.

22

If your redemption request is not accurate and complete, it may be rejected. If we are unable to send your redemption proceeds by wire or electronic bank transfer because the receiving institution rejects the transfer, Vanguard will make additional efforts to complete your transaction. If Vanguard is still unable to complete the transaction, we may send the proceeds of the redemption to you by check, generally payable to all registered account owners, or use your proceeds to purchase new shares of the fund from which you sold shares for the purpose of the wire or electronic bank transfer transaction. See Other Rules You Should Know—Good Order.

If your redemption request is received in good order, we typically expect that redemption proceeds will be paid by the Fund within one business day of the trade date; however, in certain circumstances, investors may experience a longer settlement period at the time of the transaction. For further information, see "Potentially disruptive redemptions" and "Emergency circumstances."

For further information about redemption transactions, consult our website at vanguard.com or see Contacting Vanguard.

Other Redemption Rules You Should Know

Documentation for certain accounts. Special documentation may be required to redeem from certain types of accounts, such as trust, corporate, nonprofit, or retirement accounts. Please call us before attempting to redeem from these types of accounts.

Potentially disruptive redemptions. Vanguard reserves the right to pay all or part of a redemption in kind—that is, in the form of securities—if we reasonably believe that a cash redemption would negatively affect the fund's operation or performance or that the shareholder may be engaged in market-timing or frequent trading. Under these circumstances, Vanguard also reserves the right to delay payment of the redemption proceeds for up to seven calendar days. By calling us before you attempt to redeem a large dollar amount, you may avoid in-kind or delayed payment of your redemption. Please see Frequent-Trading Limitations for information about Vanguard's policies to limit frequent trading.

Recently purchased shares. Although you can redeem shares at any time, proceeds may not be made available to you until the fund collects payment for your purchase. This may take up to seven calendar days for shares purchased by check or by electronic bank transfer. If you have written a check on a fund with checkwriting privileges, that check may be rejected if your fund account does not have a sufficient available balance.

Address change. If you change your address online or by telephone, there may be up to a 14-day restriction on your ability to request check redemptions online and by telephone. You can request a redemption in writing (using a form available online) at

23

any time. Confirmations of address changes are sent to both the old and new addresses.

Payment to a different person or address. At your request, we can make your redemption check payable, or wire your redemption proceeds, to a different person or send it to a different address. However, this generally requires the written consent of all registered account owners and may require additional documentation, such as a signature guarantee or a notarized signature. You may obtain a signature guarantee from some commercial or savings banks, credit unions, trust companies, or member firms of a U.S. stock exchange.

No cancellations. Vanguard will not accept your request to cancel any redemption request once processing has begun. Please be careful when placing a redemption request.

Emergency circumstances. Vanguard funds can postpone payment of redemption proceeds for up to seven calendar days. In addition, Vanguard funds can suspend redemptions and/or postpone payments of redemption proceeds beyond seven calendar days at times when the NYSE is closed or during emergency circumstances, as determined by the SEC.

Exchanging Shares

An exchange occurs when you use the proceeds from the redemption of shares of one Vanguard fund to simultaneously purchase shares of a different Vanguard fund. You can make exchange requests online (if you are registered for online access), by telephone, or by mail. See Purchasing Shares and Redeeming Shares.

If the NYSE is open for regular trading (generally until 4 p.m., Eastern time, on a business day) at the time an exchange request is received in good order, the trade date generally will be the same day. See Other Rules You Should Know—Good Order for additional information on all transaction requests.

Vanguard will not accept your request to cancel any exchange request once processing has begun. Please be careful when placing an exchange request.

Call Vanguard before attempting to exchange a large dollar amount. By calling us before you attempt to exchange a large dollar amount, you may avoid delayed or rejected transactions.

Please note that Vanguard reserves the right, without notice, to revise or terminate the exchange privilege, limit the amount of any exchange, or reject an exchange, at any time, for any reason. See Frequent-Trading Limitations for additional restrictions on exchanges.

24

Frequent-Trading Limitations

Because excessive transactions can disrupt management of a fund and increase the fund's costs for all shareholders, the board of trustees of each Vanguard fund places certain limits on frequent trading in the funds. Each Vanguard fund (other than money market funds and short-term bond funds, but including Vanguard Short-Term Inflation- Protected Securities Index Fund) limits an investor's purchases or exchanges into a fund account for 30 calendar days after the investor has redeemed or exchanged out of that fund account. ETF Shares are not subject to these frequent-trading limits.

For Vanguard Retirement Investment Program pooled plans, the limitations apply to exchanges made online or by telephone.

These frequent-trading limitations do not apply to the following:

•Purchases of shares with reinvested dividend or capital gains distributions.

•Transactions through Vanguard's Automatic Investment Plan, Automatic Exchange Service, Direct Deposit Service, Automatic Withdrawal Plan, Required Minimum Distribution Service, and Vanguard Small Business Online®.

•Discretionary transactions through Vanguard Personal Advisor Services®, Vanguard Institutional Advisory Services®, and Vanguard Digital AdvisorTM.

•Redemptions of shares to pay fund or account fees.

•Redemptions of shares to remove excess shareholder contributions to certain types of retirement accounts (including, but not limited to, IRAs and Vanguard Individual 401(k) Plans).

•Transfers and reregistrations of shares within the same fund.

•Purchases of shares by asset transfer or direct rollover.

•Conversions of shares from one share class to another in the same fund.

•Checkwriting redemptions.

•Section 529 college savings plans.

•Certain approved institutional portfolios and asset allocation programs, as well as trades made by funds or trusts managed by Vanguard or its affiliates that invest in other Vanguard funds. (Please note that shareholders of Vanguard's funds of funds are subject to the limitations.)

For participants in employer-sponsored defined contribution plans,* the frequent- trading limitations do not apply to:

•Purchases of shares with participant payroll or employer contributions or loan repayments.

•Purchases of shares with reinvested dividend or capital gains distributions.

•Distributions, loans, and in-service withdrawals from a plan.

25

•Redemptions of shares as part of a plan termination or at the direction of the plan.

•Transactions executed through the Vanguard Managed Account Program.

•Redemptions of shares to pay fund or account fees.

•Share or asset transfers or rollovers.

•Reregistrations of shares.

•Conversions of shares from one share class to another in the same fund.

•Exchange requests submitted by written request to Vanguard. (Exchange requests submitted by fax, if otherwise permitted, are subject to the limitations.)

*The following Vanguard fund accounts are subject to the frequent-trading limitations: SEP-IRAs, SIMPLE IRAs, certain Individual 403(b)(7) Custodial Accounts, and Vanguard Individual 401(k) Plans.

Accounts Held by Institutions (Other Than Defined Contribution Plans)

Vanguard will systematically monitor for frequent trading in institutional clients' accounts. If we detect suspicious trading activity, we will investigate and take appropriate action, which may include applying to a client's accounts the 30-day policy previously described, prohibiting a client's purchases of fund shares, and/or revoking the client's exchange privilege.

Accounts Held by Intermediaries

When intermediaries establish accounts in Vanguard funds for the benefit of their clients, we cannot always monitor the trading activity of the individual clients. However, we review trading activity at the intermediary (omnibus) level, and if we detect suspicious activity, we will investigate and take appropriate action. If necessary, Vanguard may prohibit additional purchases of fund shares by an intermediary, including for the benefit of certain of the intermediary's clients. Intermediaries also may monitor their clients' trading activities with respect to Vanguard funds.

For those Vanguard funds that charge purchase and/or redemption fees, intermediaries will be asked to assess these fees on client accounts and remit these fees to the funds. The application of purchase and redemption fees and frequent- trading limitations may vary among intermediaries. There are no assurances that Vanguard will successfully identify all intermediaries or that intermediaries will properly assess purchase and redemption fees or administer frequent-trading limitations. If you invest with Vanguard through an intermediary, please read that firm's materials carefully to learn of any other rules or fees that may apply.

Investing With Vanguard Through Other Firms

You may purchase or sell shares of most Vanguard funds through a financial intermediary, such as a bank, a broker, or an investment advisor. Please consult your financial intermediary to determine which, if any, shares are available through that firm and to learn about other rules that may apply. Your financial intermediary can provide you with account information and any required tax forms. You may be required to pay a commission on purchases of mutual fund shares made through a financial intermediary.

Please see Frequent-Trading Limitations—Accounts Held by Intermediaries for information about the assessment of any purchase or redemption fees and the monitoring of frequent trading for accounts held by intermediaries.

Account Service Fee

Vanguard may charge a $20 account service fee on fund accounts that have a balance below $10,000 for any reason, including market fluctuation. The account service fee applies to both retirement and nonretirement fund accounts and may be assessed on fund accounts in all Vanguard funds, regardless of the account minimum. The fee, which will be collected by redeeming fund shares in the amount of $20, will be deducted from fund accounts subject to the fee once per calendar year.

If you elect to receive your statements and other materials electronically (i.e., by e-delivery), the account service fee will not be charged, so long as your election remains in effect. You can make your e-delivery election on vanguard.com.

Beginning on January 1, 2021, you may elect to receive paper copies of shareholder reports free of charge as noted on the cover of this prospectus.

29

Certain account types have alternative fee structures, including SIMPLE IRAs, Vanguard Retirement Investment Program pooled plans, and Vanguard Individual 401(k) Plans.

Low-Balance Accounts

The Fund reserves the right to liquidate a fund account whose balance falls below the account minimum for any reason, including market fluctuation. This liquidation policy applies to nonretirement fund accounts and accounts that are held through intermediaries. Any such liquidation will be preceded by written notice to the investor.

Right to Change Policies

In addition to the rights expressly stated elsewhere in this prospectus, Vanguard reserves the right, without notice, to (1) alter, add, or discontinue any conditions of purchase (including eligibility requirements), redemption, exchange, service, or privilege at any time and (2) alter, impose, discontinue, or waive any purchase fee, redemption fee, account service fee, or other fee charged to a shareholder or a group of shareholders.

Consult your recordkeeper or plan administrator for more information.

If Vanguard is serving as your plan recordkeeper and if your transaction involves one or more investments with an early cut-off time for processing or another trading restriction, your entire transaction will be subject to the restriction when the trade date for your transaction is determined.

Example

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you were to invest $10,000 in the Fund's shares. This example assumes that the Fund provides a return of 5% each year and that total annual fund operating expenses remain as stated in the preceding table. You would incur these hypothetical expenses whether or not you were to redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years	5 Years	10 Years
$95	$296	$515	$1,143

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 46% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests mainly in equity securities of companies located in emerging markets. The Fund invests in small-, mid-, and large-capitalization companies and is expected to diversify its assets among companies located in emerging markets around the world.

Under normal circumstances, at least 80% of the Fund's assets will be invested in common stocks of companies located in emerging markets. A company is considered to be located in an emerging market if it is organized under the laws of, or has a principal office in, an emerging country; has a class of securities whose principal securities market is in an emerging country; derives 50% or more of its total revenue from goods produced, sales made, or services provided in one or more emerging countries; or maintains 50% or more of its assets in one or more emerging countries. The Fund uses multiple investment advisors. Each advisor independently selects and maintains a portfolio of equity securities for the Fund.

Principal Risks

An investment in the Fund could lose money over short or long periods of time. You should expect the Fund's share price and total return to fluctuate within a wide range. The Fund is subject to the following risks, which could affect the Fund's performance:

•Stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. The Fund's investments in foreign stocks can be riskier than U.S. stock investments. Foreign stocks may be more volatile and less liquid than U.S. stocks. The prices of foreign stocks and the prices of U.S. stocks may move in opposite directions.

•Emerging markets risk, which is the chance that the stocks of companies located in emerging markets will be substantially more volatile, and substantially less liquid, than the stocks of companies located in more developed foreign markets because, among other factors, emerging markets can have greater custodial and operational risks; less developed legal, tax, regulatory, and accounting systems; and greater political, social, and economic instability than developed markets.

•Country/regional risk, which is the chance that world events—such as political upheaval, financial troubles, or natural disasters—will adversely affect the value of

securities issued by companies in foreign countries or regions. Because the Fund may invest a large portion of its assets in securities of companies located in any one country or region, the Fund's performance may be hurt disproportionately by the poor performance of its investments in that area. Country/regional risk is especially high in emerging markets.

•Currency risk, which is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates. Currency risk is especially high in emerging markets.

•Investment style risk, which is the chance that returns from the types of stocks in which the Fund invests will trail returns from global stock markets. Small-, mid-, and large-cap stocks each tend to go through cycles of doing better—or worse—than other segments of the stock market or the global market in general. These periods have, in the past, lasted for as long as several years. Historically, small- and mid-cap stocks have been more volatile in price than large-cap stocks. The stock prices of small and mid-size companies tend to experience greater volatility because, among other things, these companies tend to be more sensitive to changing economic conditions.

•Manager risk, which is the chance that poor security selection will cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective. In addition, significant investment in the financial sector subjects the Fund to proportionately higher exposure to the risks of this sector.

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Actual after-tax returns depend on your tax situation and may differ from those shown in the preceding table. When after-tax returns are calculated, it is assumed that the shareholder was in the highest individual federal marginal income tax bracket at the time of each distribution of income or capital gains or upon redemption. State and local income taxes are not reflected in the calculations. Please note that after-tax returns are not relevant for a shareholder who holds fund shares in a tax-deferred account, such as an individual retirement account or a 401(k) plan. Also, figures captioned Return After Taxes on Distributions and Sale of Fund Shares may be higher than other figures for the same period if a capital loss occurs upon redemption and results in an assumed tax deduction for the shareholder.
