Fund/Class:
Spartan^® Extended Market Index Fund/Investor, Fidelity Advantage^®

Investment Objective

The fund seeks to provide investment results that correspond to the total return of stocks of mid- to small-capitalization United States companies.

Fee Table

The following table describes the fees and expenses that may be incurred when you buy, hold, or sell shares of the fund.

Shareholder fees (fees paid directly from your investment)
	Investor Class	Fidelity Advantage® Class
Redemption fee on shares held less than 90 days (as a % of amount redeemed)	0.75%	0.75%
Annual index fund fee (for fund balances under $10,000)	$10.00	$10.00

Summary Prospectus

This example helps compare the cost of investing in the fund with the cost of investing in other mutual funds.

Let's say, hypothetically, that the annual return for shares of the fund is 5% and that your shareholder fees and the annual operating expenses for shares of the fund are exactly as described in the fee table. This example illustrates the effect of fees and expenses, but is not meant to suggest actual or expected fees and expenses or returns, all of which may vary. For every $10,000 you invested, here's how much you would pay in total expenses if you sell all of your shares at the end of each time period indicated:

	Investor Class	Fidelity Advantage Class
1 year	$ 10	$ 7
3 years	$ 32	$ 23
5 years	$ 56	$ 40
10 years	$ 128	$ 90

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 higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 8% of the average value of its portfolio.

Principal Investment Strategies

• Normally investing at least 80% of assets in common stocks included in the Dow Jones U.S. Completion Total Stock Market Index^SM, which represents the performance of stocks of mid- to small-capitalization U.S. companies.
• Using statistical sampling techniques based on such factors as capitalization, industry exposures, dividend yield, price/earnings (P/E) ratio, price/book (P/B) ratio, and earnings growth to attempt to replicate the returns of the Dow Jones U.S. Completion Total Stock Market Index^SM using a smaller number of securities.
• Lending securities to earn income for the fund.

Principal Investment Risks

• Stock Market Volatility. Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. Different parts of the market can react differently to these developments.
• Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.

Fund Summary - continued

• Small Cap Investing. The value of securities of smaller, less well-known issuers can perform differently from the market as a whole and other types of stocks and can be more volatile than that of larger issuers.

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. You could lose money by investing in the fund.
