Example

The following example is intended to help you compare the cost of investing in Consumer Discretionary ETF with the cost of investing in other funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in Consumer Discretionary ETF. This example assumes that Consumer Discretionary ETF provides a return of 5% a year and that total annual fund operating expenses remain as stated in the preceding table. The results apply whether or not you 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:

This example does not include the brokerage commissions that you may pay to buy and sell ETF Shares of the Fund.

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 6%.

Primary Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of the MSCI US Investable Market Index (IMI)/Consumer Discretionary 25/50, an index made up of stocks of large, mid-size, and small U.S. companies within the consumer discretionary sector, as classified under the Global Industry Classification Standard (GICS). The GICS consumer discretionary sector is made up of those manufacturing and service industries that tend to be the most sensitive to economic cycles. Its manufacturing segment includes the following industries: automotive, household durable goods, textiles and apparel, and leisure equipment. The services segment includes hotels, restaurants and other leisure facilities, media production and services, and consumer retailing.

The Fund attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund's share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. 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.

Sector risk, which is the chance that significant problems will affect a particular sector, or that returns from that sector will trail returns from the overall stock market. Daily fluctuations in specific market sectors are often more extreme than fluctuations in the overall market. Because the Fund invests all, or substantially all, of its assets in the consumer discretionary sector, the Fund's performance largely depends-for better or for worse-on the general condition of that sector. Companies in the consumer discretionary sector could be affected by, among other things, overall economic conditions, interest rates, consumer confidence, and disposable income.

Nondiversification risk, which is the chance that the Fund's performance may be hurt disproportionately by the poor performance of relatively few stocks or even a single stock. The Fund is considered nondiversified, which means that it may invest a greater percentage of its assets in the securities of a small number of issuers as compared with other mutual funds. Because the Fund tends to invest a relatively high percentage of its assets in its ten largest holdings and in its single largest holding, nondiversification risk is high for the Fund.

Investment style risk, which is the chance that returns from small- and mid-capitalization stocks (to the extent that the Fund's assets are invested in small- and mid-cap stocks) 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 market, and they often perform quite differently.

Because ETF Shares are traded on an exchange, they are subject to additional risks:

Consumer Discretionary ETF Shares are listed for trading on NYSE Arca and are bought and sold on the secondary market at market prices. Although it is expected that the market price of a Consumer Discretionary ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly. Thus, you may pay more or less than NAV when you buy Consumer Discretionary ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.

Although Consumer Discretionary ETF Shares are listed for trading on NYSE Arca, it is possible that an active trading market may not be maintained.

Trading of Consumer Discretionary ETF Shares on NYSE Arca may be halted by the activation of individual or marketwide 'circuit breakers' (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of Consumer Discretionary ETF Shares may also be halted if (1) the shares are delisted from NYSE Arca without first being listed on another exchange or (2) NYSE Arca officials determine that such action is appropriate in the interest of a fair and orderly market or to protect investors.

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's ETF Shares(based on NAV) has varied from one calendar year to another over the periods shown. The table shows how the average annual total returns of the ETF Shares compare with those of the Fund's target Index and other comparative indexes, which have investment characteristics similar to those of the Fund. Keep in mind that the Fund's past performance (before and after taxes) does not indicate how the Fund will perform in the future.

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 will 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.

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 will 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.

Investment Objective

The Fund seeks to track the performance of a benchmark index that measures the investment return of energy stocks.

Fees and Expenses

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

Shareholder Fees (Fees paid directly from your investment)
Shareholder Fees (Vanguard Energy Index Fund ETF) Vanguard Energy Index Fund

Example

The following example is intended to help you compare the cost of investing in Energy ETF with the cost of investing in other funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in Energy ETF. This example assumes that Energy ETF provides a return of 5% a year and that total annual fund operating expenses remain as stated in the preceding table. The results apply whether or not you 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:

Expense Example, No Redemption (Vanguard Energy Index Fund ETF) Vanguard Energy Index Fund (USD $)
1 YEAR
3 YEAR
5 YEAR
10 YEAR
Vanguard Energy Index Fund - ETF Shares
14 45 79 179

This example does not include the brokerage commissions that you may pay to buy and sell ETF Shares of the Fund.

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 12%.

Primary Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of the MSCI US Investable Market Index (IMI)/ Energy 25/50, an index made up of stocks of large, mid-size, and small U.S. companies within the energy sector, as classified under the Global Industry Classification Standard (GICS). The GICS energy sector is made up of companies whose businesses are dominated by either of the following activities: the construction or provision of oil rigs, drilling equipment, and other energy-related equipment and services (such as seismic data collection); or companies engaged in the exploration, production, marketing, refining, and/or transportation of oil and gas products.

The Fund attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund's share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. 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.

Sector risk, which is the chance that significant problems will affect a particular sector, or that returns from that sector will trail returns from the overall stock market. Daily fluctuations in specific market sectors are often more extreme than fluctuations in the overall market. Because the Fund invests all, or substantially all, of its assets in the energy sector, the Fund's performance largely depends-for better or for worse-on the general condition of that sector. Companies in the energy sector could be affected by, among other things, geopolitical events, government regulation, economic cycles, and fuel prices.

Nondiversification risk, which is the chance that the Fund's performance may be hurt disproportionately by the poor performance of relatively few stocks or even a single stock. The Fund is considered nondiversified, which means that it may invest a greater percentage of its assets in the securities of a small number of issuers as compared with other mutual funds. Because the Fund tends to invest a relatively high percentage of its assets in its ten largest holdings and in its single largest holding, nondiversification risk is high for the Fund.

Investment style risk, which is the chance that returns from small- and mid-capitalization stocks (to the extent that the Fund's assets are invested in small- and mid-cap stocks) 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 market, and they often perform quite differently.

Because ETF Shares are traded on an exchange, they are subject to additional risks:

Energy ETF Shares are listed for trading on NYSE Arca and are bought and sold on the secondary market at market prices. Although it is expected that the market price of an Energy ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly. Thus, you may pay more or less than NAV when you buy Energy ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.

Although Energy ETF Shares are listed for trading on NYSE Arca, it is possible that an active trading market may not be maintained.

Trading of Energy ETF Shares on NYSE Arca may be halted by the activation of individual or marketwide 'circuit breakers' (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of Energy ETF Shares may also be halted if (1) the shares are delisted from NYSE Arca without first being listed on another exchange or (2) NYSE Arca officials determine that such action is appropriate in the interest of a fair and orderly market or to protect investors.

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.

The bar chart shows how the performance of the Fund's ETF Shares(based on NAV) has varied from one calendar year to another over the periods shown.

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 47%.

Primary Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of the Barclays U.S. Treasury STRIPS 20-30 Year Equal Par Bond Index. This Index includes zero-coupon U.S. Treasury securities (Treasury STRIPS) with maturities ranging from 20 to 30 years. A Treasury STRIP represents a single coupon payment, or a single principal payment, from a U.S. Treasury security that has been 'stripped' into separately tradable components.

The Fund invests by sampling the Index, meaning that it holds a range of securities that, in the aggregate, approximates the full Index in terms of key risk factors, including duration and other characteristics. All of the Fund's investments will be selected through the sampling process, and at least 80% of the Fund's assets will be invested in U.S. Treasury securities held in the Index. The Fund maintains a dollar-weighted average maturity consistent with that of the Index, which generally ranges between 20 and 30 years. The Fund is expected to have a duration that is greater than 20 years.

Primary Risks

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

Interest rate risk, which is the chance that bond prices overall will decline because of rising interest rates. Interest rate risk is expected to be extremely high for the Fund because it invests primarily in zero-coupon long-term bonds, which have prices that are even more sensitive to interest rate changes than are coupon-bearing bonds of similar maturity. Because the Fund invests primarily in Treasury STRIPS with maturities ranging from 20 to 30 years, rising interest rates may cause the value of the Fund's investments to decline significantly.

Index sampling risk, which is the chance that the securities selected for the Fund, in the aggregate, will not provide investment performance matching that of the Fund's target index. Index sampling risk for the Fund should be low.

Because ETF Shares are traded on an exchange, they are subject to additional risks:

Extended Duration Treasury ETF Shares are listed for trading on NYSE Arca and are bought and sold on the secondary market at market prices. Although it is expected that the market price of an Extended Duration Treasury ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly.

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 will 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.

Investment Objective

The Fund seeks to track the performance of a benchmark index that measures the investment return of financial stocks.

Fees and Expenses

The following table describes the fees and expenses you may pay if you buy and hold ETF Shares of the Fund. 'Acquired Fund Fees and Expenses' are expenses incurred indirectly by the Fund through its ownership of shares in other investment companies, such as business development companies. Business development company expenses are similar to the expenses paid by any operating company held by the Fund. They are not direct costs paid by Fund shareholders and are not used to calculate the Fund's net asset value. They have no impact on the costs associated with fund operations.

Example

The following example is intended to help you compare the cost of investing in Financials ETF with the cost of investing in other funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in Financials ETF. This example assumes that Financials ETF provides a return of 5% a year and that total annual fund operating expenses remain as stated in the preceding table. The results apply whether or not you 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:

5 YEAR
10 YEAR
Vanguard Financials Index Fund - ETF Shares

This example does not include the brokerage commissions that you may pay to buy and sell ETF Shares of the Fund.

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 7%.

Primary Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of the MSCI US Investable Market Index (IMI)/Financials 25/50, an index made up of stocks of large, mid-size, and small U.S. companies within the financials sector, as classified under the Global Industry Classification Standard (GICS). The GICS financials sector is made up of companies involved in activities such as banking, mortgage finance, consumer finance, specialized finance, investment banking and brokerage, asset management and custody, corporate lending, insurance, financial investment, and real estate (including real estate investment trusts).

The Fund attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund's share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. 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.

Sector risk, which is the chance that significant problems will affect a particular sector, or that returns from that sector will trail returns from the overall stock market. Daily fluctuations in specific market sectors are often more extreme than fluctuations in the overall market. Because the Fund invests all, or substantially all, of its assets in the financials sector, the Fund's performance largely depends-for better or for worse-on the general condition of that sector. Companies in the financials sector could be affected by, among other things, government regulation, interest rates, cost of capital funds, credit losses, and financial markets.

Nondiversification risk, which is the chance that the Fund's performance may be hurt disproportionately by the poor performance of relatively few stocks or even a single stock. The Fund is considered nondiversified, which means that it may invest a greater percentage of its assets in the securities of a small number of issuers as compared with other mutual funds. Because the Fund tends to invest a relatively high percentage of its assets in its ten largest holdings and in its single largest holding, nondiversification risk is high for the Fund.

Investment style risk, which is the chance that returns from small- and mid-capitalization stocks (to the extent that the Fund's assets are invested in small- and mid-cap stocks) 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 market, and they often perform quite differently.

Because ETF Shares are traded on an exchange, they are subject to additional risks:

Financials ETF Shares are listed for trading on NYSE Arca and are bought and sold on the secondary market at market prices. Although it is expected that the market price of a Financials ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly. Thus, you may pay more or less than NAV when you buy Financials ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.

Although Financials ETF Shares are listed for trading on NYSE Arca, it is possible that an active trading market may not be maintained.

Trading of Financials ETF Shares on NYSE Arca may be halted by the activation of individual or marketwide 'circuit breakers' (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of Financials ETF Shares may also be halted if (1) the shares are delisted from NYSE Arca without first being listed on another exchange or (2) NYSE Arca officials determine that such action is appropriate in the interest of a fair and orderly market or to protect investors.

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's ETF Shares(based on NAV) has varied from one calendar year to another over the periods shown. The table shows how the average annual total returns of the ETF Shares compare with those of the Fund's target Index and other comparative indexes, which have investment characteristics similar to those of the Fund. Keep in mind that the Fund's past performance (before and after taxes) does not indicate how the Fund will perform in the future.

This example assumes that the Shares provide a return of 5% a year and that total annual fund operating expenses remain as stated in the preceding table. The results apply whether or not you 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:

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 45%.

Primary Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of the FTSE4Good US Select Index. The Index is composed primarily of large- and mid-cap stocks that have been screened for certain social and environmental criteria by the Index sponsor, which is independent of Vanguard. The Fund attempts to replicate the Index by investing all, or substantially all, of its assets in the stocks that make up the Index.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund's share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. 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 target index may, at times, become focused in stocks of a particular sector, category, or group of companies, which could cause the Fund to underperform the overall stock market.

Investment style risk, which is the chance that the stocks selected for the FTSE4Good US Select Index will, in the aggregate, trail returns of other mutual funds screened with similar criteria, of other asset classes, or of the overall stock market. Historically, mid-cap stocks, which make up part of the Index, have been more volatile in price than the large-cap stocks that dominate the overall market, and they often perform quite differently.

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's Investor Shares has varied from one calendar year to another over the periods shown. The table shows how the average annual total returns of the Investor Shares compare with those of the Fund's target index and other comparative indexes, which have investment characteristics similar to those of the Fund. Keep in mind that the Fund's past performance (before and after taxes) does not indicate how the Fund will perform in the future.

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 will 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.

This example assumes that Health Care ETF provides a return of 5% a year and that total annual fund operating expenses remain as stated in the preceding table. The results apply whether or not you 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:

This example does not include the brokerage commissions that you may pay to buy and sell ETF Shares of the Fund.

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 9%.

Primary Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of the MSCI US Investable Market Index (IMI)/Health Care 25/50, an index made up of stocks of large, mid-size, and small U.S. companies within the health care sector, as classified under the Global Industry Classification Standard (GICS). The GICS health care sector is made up of two main industry groups. The first group includes companies that manufacture health care equipment and supplies or provide health care-related services (such as distributors of health care products, providers of basic health care services, and owners and operators of health care facilities and organizations). The second group includes companies primarily involved in the research, development, production, and marketing of pharmaceuticals and biotechnology products.

The Fund attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund's share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. 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.

Sector risk, which is the chance that significant problems will affect a particular sector, or that returns from that sector will trail returns from the overall stock market. Daily fluctuations in specific market sectors are often more extreme than fluctuations in the overall market. Because the Fund invests all, or substantially all, of its assets in the health care sector, the Fund's performance largely depends-for better or for worse-on the general condition of that sector. Companies in the health care sector could be affected by, among other things, patent protection, government regulation, research and development costs, litigation, and competitive forces.

Nondiversification risk, which is the chance that the Fund's performance may be hurt disproportionately by the poor performance of relatively few stocks or even a single stock. The Fund is considered nondiversified, which means that it may invest a greater percentage of its assets in the securities of a small number of issuers as compared with other mutual funds. Because the Fund tends to invest a relatively high percentage of its assets in its ten largest holdings and in its single largest holding, nondiversification risk is high for the Fund.

Investment style risk, which is the chance that returns from small- and mid-capitalization stocks (to the extent that the Fund's assets are invested in small- and mid-cap stocks) 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 market, and they often perform quite differently.

Because ETF Shares are traded on an exchange, they are subject to additional risks:

Health Care ETF Shares are listed for trading on NYSE Arca and are bought and sold on the secondary market at market prices. Although it is expected that the market price of a Health Care ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly. Thus, you may pay more or less than NAV when you buy Health Care ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.

Although Health Care ETF Shares are listed for trading on NYSE Arca, it is possible that an active trading market may not be maintained.

Trading of Health Care ETF Shares on NYSE Arca may be halted by the activation of individual or marketwide 'circuit breakers' (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of Health Care ETF Shares may also be halted if (1) the shares are delisted from NYSE Arca without first being listed on another exchange or (2) NYSE Arca officials determine that such action is appropriate in the interest of a fair and orderly market or to protect investors.

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.

Example

The following example is intended to help you compare the cost of investing in the Fund's Admiral Shares with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund's shares. This example assumes that the Shares provide a return of 5% a year and that total annual fund operating expenses remain as stated in the preceding table. The results apply whether or not you 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:

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 6%.

Primary Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of the MSCI US Investable Market Index (IMI)/Industrials 25/50, an index made up of stocks of large, mid-size, and small U.S. companies within the industrials sector, as classified under the Global Industry Classification Standard (GICS). The GICS industrials sector is made up of companies whose businesses are dominated by one of the following activities: the manufacture and distribution of capital goods (including aerospace and defense; construction, engineering, and building products; electrical equipment; and industrial machinery); the provision of commercial services and supplies (including printing, employment, environmental, and office services); or the provision of transportation services (including airlines, couriers, marine, road, and rail) and transportation infrastructure.

The Fund attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund's share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. 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.

Sector risk, which is the chance that significant problems will affect a particular sector, or that returns from that sector will trail returns from the overall stock market. Daily fluctuations in specific market sectors are often more extreme than fluctuations in the overall market. Because the Fund invests all, or substantially all, of its assets in the industrials sector, the Fund's performance largely depends-for better or for worse-on the general condition of that sector. Companies in the industrials sector could be affected by, among other things, government regulation, world events and economic conditions, insurance costs, and labor relations.

Nondiversification risk, which is the chance that the Fund's performance may be hurt disproportionately by the poor performance of relatively few stocks or even a single stock. The Fund is considered nondiversified, which means that it may invest a greater percentage of its assets in the securities of a small number of issuers as compared with other mutual funds. Because the Fund tends to invest a relatively high percentage of its assets in its ten largest holdings and in its single largest holding, nondiversification risk is high for the Fund.

Investment style risk, which is the chance that returns from small- and mid-capitalization stocks (to the extent that the Fund's assets are invested in small- and mid-cap stocks) 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 market, and they often perform quite differently.

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's Admiral Shares has varied from one calendar year to another over the periods shown. The table shows how the average annual total returns of the Admiral Shares compare with those of the Fund's target Index and other comparative indexes, which have investment characteristics similar to those of the Fund. Keep in mind that the Fund's past performance (before and after taxes) does not indicate how the Fund will perform in the future.

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 will 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.

During the most recent fiscal year, the Fund's portfolio turnover rate was 6%.

Primary Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of the MSCI US Investable Market Index (IMI)/Information Technology 25/50, an index made up of stocks of large, mid-size, and small U.S. companies within the information technology sector, as classified under the Global Industry Classification Standard (GICS). The GICS information technology sector is made up of companies in the following three general areas: technology software and services, including companies that primarily develop software in various fields (such as the Internet, applications, systems, databases, management, and/or home entertainment) and companies that provide information technology consulting and services, data processing, and outsourced services; technology hardware and equipment, including manufacturers and distributors of communications equipment, computers and peripherals, electronic equipment, and related instruments; and semiconductors and semiconductor equipment manufacturers.

The Fund attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

Primary Risks

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

Sector risk, which is the chance that significant problems will affect a particular sector, or that returns from that sector will trail returns from the overall stock market. Daily fluctuations in specific market sectors are often more extreme than fluctuations in the overall market. Because the Fund invests all, or substantially all, of its assets in the information technology sector, the Fund's performance largely depends-for better or for worse-on the general condition of that sector. Companies in the information technology sector could be affected by, among other things, overall economic conditions, short product cycles, rapid obsolescence of products, competition, and government regulation.

Nondiversification risk, which is the chance that the Fund's performance may be hurt disproportionately by the poor performance of relatively few stocks or even a single stock. The Fund is considered nondiversified, which means that it may invest a greater percentage of its assets in the securities of a small number of issuers as compared with other mutual funds.

Historically, small- and mid-cap stocks have been more volatile in price than the large-cap stocks that dominate the overall market, and they often perform quite differently.

Because ETF Shares are traded on an exchange, they are subject to additional risks:

Information Technology ETF Shares are listed for trading on NYSE Arca and are bought and sold on the secondary market at market prices. Although it is expected that the market price of an Information Technology ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly. Thus, you may pay more or less than NAV when you buy Information Technology ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.

Although Information Technology ETF Shares are listed for trading on NYSE Arca, it is possible that an active trading market may not be maintained.

Trading of Information Technology ETF Shares on NYSE Arca may be halted by the activation of individual or marketwide 'circuit breakers' (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of Information Technology ETF Shares may also be halted if (1) the shares are delisted from NYSE Arca without first being listed on another exchange or (2) NYSE Arca officials determine that such action is appropriate in the interest of a fair and orderly market or to protect investors.

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.

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 30%.

Primary Investment Strategies

The Fund invests predominantly in the stocks of companies located outside the United States and is expected to diversify its assets across developed and emerging markets in Europe, the Far East, and Latin America. In selecting stocks, the Fund's advisors evaluate foreign markets around the world and choose large-, mid-, and small-capitalization companies considered to have above-average growth potential. The Fund uses multiple investment advisors.

Primary Risks

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

Investment style risk, which is the chance that returns from non-U.S. growth stocks and, to the extent that the Fund is invested in them, small- and mid-cap stocks, will trail returns from global stock markets. Historically, non-U.S. small- and mid-cap stocks have been more volatile in price than the large-cap stocks that dominate the global markets, and they often perform quite differently.

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. In addition, investments in foreign stocks can be riskier than U.S. stock investments. The prices of foreign stocks and the prices of U.S. stocks have, at times, moved in opposite directions.

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, including emerging markets, 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.

Manager risk, which is the chance that poor security selection or focus on securities in a particular sector, category, or group of companies will cause the Fund to underperform relevant benchmarks or 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.

During the most recent fiscal year, the Fund's portfolio turnover rate was 30%.

The Fund invests predominantly in the stocks of companies located outside the United States and is expected to diversify its assets across developed and emerging markets in Europe, the Far East, and Latin America. In selecting stocks, the Fund's advisors evaluate foreign markets around the world and choose large-, mid-, and small-capitalization companies considered to have above-average growth potential. The Fund uses multiple investment advisors.

Primary Risks

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

Investment style risk, which is the chance that returns from non-U.S. growth stocks and, to the extent that the Fund is invested in them, small- and mid-cap stocks, will trail returns from global stock markets. Historically, non-U.S. small- and mid-cap stocks have been more volatile in price than the large-cap stocks that dominate the global markets, and they often perform quite differently.

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. In addition, investments in foreign stocks can be riskier than U.S. stock investments. The prices of foreign stocks and the prices of U.S. stocks have, at times, moved in opposite directions.

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, including emerging markets, 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.

Manager risk, which is the chance that poor security selection or focus on securities in a particular sector, category, or group of companies will cause the Fund to underperform relevant benchmarks or 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.

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 examples, reduce the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 30%.

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 shown only for the Investor Shares and may differ for each share class. 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 will 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.

This example does not include the brokerage commissions that you may pay to buy and sell ETF Shares of the Fund.

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 7%.

Primary Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of the MSCI US Investable Market Index (IMI)/Materials 25/50, an index made up of stocks of large, mid-size, and small U.S. companies within the materials sector, as classified under the Global Industry Classification Standard (GICS). The GICS materials sector is made up of companies in a wide range of commodity-related manufacturing industries. Included within this sector are companies that manufacture chemicals, construction materials, glass, paper, forest products, and related packaging products, as well as metals, minerals, and mining companies, including producers of steel.

The Fund attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund's share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. 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.

Sector risk, which is the chance that significant problems will affect a particular sector, or that returns from that sector will trail returns from the overall stock market. Daily fluctuations in specific market sectors are often more extreme than fluctuations in the overall market. Because the Fund invests all, or substantially all, of its assets in the materials sector, the Fund's performance largely depends-for better or for worse-on the general condition of that sector. Companies in the materials sector could be affected by, among other things, commodity prices, government regulation, inflation expectations, resource availability, and economic cycles.

Nondiversification risk, which is the chance that the Fund's performance may be hurt disproportionately by the poor performance of relatively few stocks or even a single stock. The Fund is considered nondiversified, which means that it may invest a greater percentage of its assets in the securities of a small number of issuers as compared with other mutual funds. Because the Fund tends to invest a relatively high percentage of its assets in its ten largest holdings and in its single largest holding, nondiversification risk is high for the Fund.

Investment style risk, which is the chance that returns from small- and mid-capitalization stocks (to the extent that the Fund's assets are invested in small- and mid-cap stocks) 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 market, and they often perform quite differently.

Because ETF Shares are traded on an exchange, they are subject to additional risks:

Materials ETF Shares are listed for trading on NYSE Arca and are bought and sold on the secondary market at market prices. Although it is expected that the market price of a Materials ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly. Thus, you may pay more or less than NAV when you buy Materials ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.

Although Materials ETF Shares are listed for trading on NYSE Arca, it is possible that an active trading market may not be maintained.

Trading of Materials ETF Shares on NYSE Arca may be halted by the activation of individual or marketwide 'circuit breakers' (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of Materials ETF Shares may also be halted if (1) the shares are delisted from NYSE Arca without first being listed on another exchange or (2) NYSE Arca officials determine that such action is appropriate in the interest of a fair and orderly market or to protect investors.

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.

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 16%.

Primary Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of the MSCI US Large Cap Growth Index, which represents the growth companies of the MSCI US Large Cap 300 Index. The Index is a free-float-adjusted, market-capitalization-weighted index designed to measure equity market performance of large-capitalization growth stocks. The Fund attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

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 target index may, at times, become focused in stocks of a particular sector, category, or group of companies, which could cause the Fund to underperform the overall stock market.

Investment style risk, which is the chance that returns from large-capitalization growth stocks will trail returns from the overall stock market. Large-cap growth stocks tend to go through cycles of doing better-or worse-than other segments of the stock market or the stock market in general. These periods have, in the past, lasted for as long as several years.

Because ETF Shares are traded on an exchange, they are subject to additional risks:

Mega Cap 300 Growth ETF Shares are listed for trading on NYSE Arca and are bought and sold on the secondary market at market prices. Although it is expected that the market price of a Mega Cap 300 Growth ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly. Thus, you may pay more or less than NAV when you buy Mega Cap 300 Growth ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.

Although Mega Cap 300 Growth ETF Shares are listed for trading on NYSE Arca, it is possible that an active trading market may not be maintained.

Trading of Mega Cap 300 Growth ETF Shares on NYSE Arca may be halted by the activation of individual or marketwide 'circuit breakers'(which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of Mega Cap 300 Growth ETF Shares may also be halted if (1) the shares are delisted from NYSE Arca without first being listed on another exchange or (2) NYSE Arca officials determine that such action is appropriate in the interest of a fair and orderly market or to protect investors.

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 will 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.

Investment Objective

The Fund seeks to track the performance of a benchmark index that measures the investment return of large-capitalization growth stocks in the United States.

Fees and Expenses

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

Shareholder Fees (Fees paid directly from your investment)

Example

The following example is intended to help you compare the cost of investing in the Fund's Institutional Shares with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund's shares. This example assumes that the Shares provide a return of 5% a year and that total annual fund operating expenses remain as stated in the preceding table. The results apply whether or not you 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:

10 YEAR

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 16%.

Primary Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of the MSCI US Large Cap Growth Index, which represents the growth companies of the MSCI US Large Cap 300 Index. The Index is a free-float-adjusted, market-capitalization-weighted index designed to measure equity market performance of large-capitalization growth stocks. The Fund attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund's share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. 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 target index may, at times, become focused in stocks of a particular sector, category, or group of companies, which could cause the Fund to underperform the overall stock market.

Investment style risk, which is the chance that returns from large-capitalization growth stocks will trail returns from the overall stock market. Large-cap growth stocks tend to go through cycles of doing better-or worse-than other segments of the stock market or the stock market in general. These periods have, in the past, lasted for as long as several years.

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.

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 will 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.

Example

The following example is intended to help you compare the cost of investing in the Fund's Institutional Shares with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund's shares. This example assumes that the Shares provide a return of 5% a year and that total annual fund operating expenses remain as stated in the preceding table. The results apply whether or not you 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:

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 17%.

Primary Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of the MSCI US Large Cap Value Index, which represents the value companies of the MSCI US Large Cap 300 Index. The Index is a free-float-adjusted, market-capitalization-weighted index designed to measure equity market performance of large-capitalization value stocks. The Fund attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund's share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. 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 target index may, at times, become focused in stocks of a particular sector, category, or group of companies, which could cause the Fund to underperform the overall stock market.

Investment style risk, which is the chance that returns from large-capitalization value stocks will trail returns from the overall stock market. Large-cap value stocks tend to go through cycles of doing better-or worse-than other segments of the stock market or the stock market in general. These periods have, in the past, lasted for as long as several years.

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's Institutional Shares has varied from one calendar year to another over the periods shown. The table shows how the average annual total returns of the Institutional Shares compare with those of the Fund's target index, which has investment characteristics similar to those of the Fund. Keep in mind that the Fund's past performance (before and after taxes) does not indicate how the Fund will perform in the future.

It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in Telecommunication Services ETF. This example assumes that Telecommunication Services ETF provides a return of 5% a year and that total annual fund operating expenses remain as stated in the preceding table. The results apply whether or not you 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:

This example does not include the brokerage commissions that you may pay to buy and sell ETF Shares of the Fund.

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 28%.

Primary Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of the MSCI US Investable Market Index (IMI)/Telecommunication Services 25/50, an index made up of stocks of large, mid-size, and small U.S. companies within the telecommunication services sector, as classified under the Global Industry Classification Standard (GICS). The GICS telecommunication services sector is made up of companies that provide communication services primarily through fixed-line, cellular, wireless, high-bandwidth, and/or fiber-optic cable networks.

The Fund attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund's share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. 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.

Sector risk, which is the chance that significant problems will affect a particular sector, or that returns from that sector will trail returns from the overall stock market. Daily fluctuations in specific market sectors are often more extreme than fluctuations in the overall market. Because the Fund invests all, or substantially all, of its assets in the telecommunication services sector, the Fund's performance largely depends-for better or for worse-on the general condition of that sector. Companies in the telecommunication services sector could be affected by, among other things, overall economic conditions, competition, and government regulation.

Nondiversification risk, which is the chance that the Fund's performance may be hurt disproportionately by the poor performance of relatively few stocks or even a single stock. The Fund is considered nondiversified, which means that it may invest a greater percentage of its assets in the securities of a small number of issuers as compared with other mutual funds. Because the Fund tends to invest a relatively high percentage of its assets in its ten largest holdings and in its single largest holding, nondiversification risk is high for the Fund.

Investment style risk, which is the chance that returns from small- and mid-capitalization stocks (to the extent that the Fund's assets are invested in small- and mid-cap stocks) 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 market, and they often perform quite differently.

Because ETF Shares are traded on an exchange, they are subject to additional risks:

Telecommunication Services ETF Shares are listed for trading on NYSE Arca and are bought and sold on the secondary market at market prices. Although it is expected that the market price of a Telecommunication Services ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly. Thus, you may pay more or less than NAV when you buy Telecommunication Services ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.

Although Telecommunication Services ETF Shares are listed for trading on NYSE Arca, it is possible that an active trading market may not be maintained.

Trading of Telecommunication Services ETF Shares on NYSE Arca may be halted by the activation of individual or marketwide 'circuit breakers' (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of Telecommunication Services ETF Shares may also be halted if (1) the shares are delisted from NYSE Arca without first being listed on another exchange or (2) NYSE Arca officials determine that such action is appropriate in the interest of a fair and orderly market or to protect investors.

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.

Investment style risk, which is the chance that returns from large-capitalization growth stocks will trail returns from the overall stock market. Large-cap growth stocks tend to go through cycles of doing better-or worse-than other segments of the stock market or the stock market in general. These periods have, in the past, lasted for as long as several years.

Asset concentration risk, which is the chance that the Fund's performance may be hurt disproportionately by the poor performance of relatively few stocks. The Fund tends to invest a high percentage of assets in its ten largest holdings.

Manager risk, which is the chance that poor security selection or focus on securities in a particular sector, category, or group of companies will cause the Fund to underperform relevant benchmarks or 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.

Examples

The following examples are intended to help you compare the cost of investing in the Fund's Investor Shares or Admiral Shares with the cost of investing in other mutual funds. They illustrate the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund's shares. These examples assume that the Shares provide a return of 5% a year and that total annual fund operating expenses remain as stated in the preceding table. The results apply whether or not you 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:

Expense Example, No Redemption (Vanguard U.S. Growth Fund Retail) Vanguard U.S. Growth Fund (USD $)

Vanguard U.S. Growth Fund - Investor Shares
46 144 252 567
Vanguard U.S. Growth Fund - Admiral Shares
32 100 174 393

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 examples, reduce the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 43%.

Primary Investment Strategies

The Fund invests mainly in large-capitalization stocks of U.S. companies considered to have above-average earnings growth potential and reasonable stock prices in comparison with expected earnings. At least 80% of the Fund's assets will be invested in stocks of U.S. companies. The Fund uses multiple investment advisors.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund's share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. 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.

Investment style risk, which is the chance that returns from large-capitalization growth stocks will trail returns from the overall stock market. Large-cap growth stocks tend to go through cycles of doing better-or worse-than other segments of the stock market or the stock market in general. These periods have, in the past, lasted for as long as several years.

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 shown only for the Investor Shares and may differ for each share class. 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 will 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.

This example does not include the brokerage commissions that you may pay to buy and sell ETF Shares of the Fund.

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 5%.

Primary Investment Strategies

The Fund employs an indexing investment approach designed to track the performance of the MSCI US Investable Market Index (IMI)/Utilities 25/50, an index made up of stocks of large, mid-size, and small U.S. companies within the utilities sector, as classified under the Global Industry Classification Standard (GICS). The GICS utilities sector is made up of electric, gas, and water utility companies, as well as companies that operate as independent producers and/or distributors of power. The sector includes both nuclear and nonnuclear facilities.

The Fund attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund's share price and total return to fluctuate within a wide range, like the fluctuations of the overall stock market. 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.

Sector risk, which is the chance that significant problems will affect a particular sector, or that returns from that sector will trail returns from the overall stock market. Daily fluctuations in specific market sectors are often more extreme than fluctuations in the overall market. Because the Fund invests all, or substantially all, of its assets in the utilities sector, the Fund's performance largely depends-for better or for worse-on the general condition of that sector. Companies in the utilities sector could be affected by government regulation, overall economic conditions, and fuel prices.

Nondiversification risk, which is the chance that the Fund's performance may be hurt disproportionately by the poor performance of relatively few stocks or even a single stock. The Fund is considered nondiversified, which means that it may invest a greater percentage of its assets in the securities of a small number of issuers as compared with other mutual funds. Because the Fund tends to invest a relatively high percentage of its assets in its ten largest holdings and in its single largest holding, nondiversification risk is high for the Fund.

Investment style risk, which is the chance that returns from small- and mid-capitalization stocks (to the extent that the Fund's assets are invested in small- and mid-cap stocks) 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 market, and they often perform quite differently.

Because ETF Shares are traded on an exchange, they are subject to additional risks:

Utilities ETF Shares are listed for trading on NYSE Arca and are bought and sold on the secondary market at market prices. Although it is expected that the market price of a Utilities ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly. Thus, you may pay more or less than NAV when you buy Utilities ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.

Although Utilities ETF Shares are listed for trading on NYSE Arca, it is possible that an active trading market may not be maintained.

Trading of Utilities ETF Shares on NYSE Arca may be halted by the activation of individual or marketwide 'circuit breakers' (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of Utilities ETF Shares may also be halted if (1) the shares are delisted from NYSE Arca without first being listed on another exchange or (2) NYSE Arca officials determine that such action is appropriate in the interest of a fair and orderly market or to protect investors.

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.
