Fund Summary

Fund:
Fidelity® Nasdaq Composite Index® Fund

Investment Objective

The fund seeks to provide investment returns that closely correspond to the price and yield performance of the Nasdaq Composite Index^® (Index).

Fee Table

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

Shareholder fees

(fees paid directly from your investment)

Redemption fee on shares held less than 90 days (as a % of amount redeemed)

0.75%

Annual Operating Expenses

(expenses that you pay each year as a % of the value of your investment)

Management fee		0.24%
Distribution and/or Service (12b-1) fees(a)		None
Other expenses		0.18%
Total annual operating expenses		0.42%
Fee Waiver and/or expense reimbursement(b)		0.13%
Total annual operating expenses after fee waiver and/or expense reimbursement		0.29%

(a)  Based on historical expenses, adjusted to reflect current fees.

(b)  Fidelity Management & Research Company (FMR) has contractually agreed to waive the fund's expenses to the extent that total operating expenses (excluding interest, certain taxes, certain securities lending costs, brokerage commissions, extraordinary expenses, and acquired fund fees and expenses, if any), as a percentage of its average net assets, exceed 0.29%. This arrangement will remain in effect through January 31, 2017. FMR may not terminate this arrangement before the expiration date without the approval of the Board of Trustees.

This example helps compare the cost of investing in the fund with the cost of investing in other 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:

1 year	$30
3 years	$119
5 years	$220
10 years	$515

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 9% of the average value of its portfolio.

Principal Investment Strategies

• Using statistical sampling techniques that take into account such factors as capitalization, industry exposures, dividend yield, price/earnings (P/E) ratio, price/book (P/B) ratio, and earnings growth to create a portfolio of securities listed in the Nasdaq Composite Index^® that have a similar investment profile to the entire index.
• Normally investing at least 80% of assets in common stocks included in the Nasdaq Composite Index^®.
• Lending securities to earn income for the fund.

Principal Investment Risks

• Stock Market Volatility.  Stock markets and, as a result, stock market indexes, are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. Different parts of the market, including different market sectors, and different types of securities can react differently to these developments. See the statement of additional information (SAI) for a description of market sectors making up the Index.

• 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. Changes in the financial condition of an issuer or counterparty (e.g., broker-dealer or other borrower in a securities lending transaction) can increase the risk of default by an issuer or counterparty, which can affect a security's or instrument's value or result in delays in recovering securities and/or capital from a counterparty. The value of securities of smaller issuers can be more volatile than that of larger issuers.

• Correlation to Index.  The performance of the fund and the Index may vary somewhat due to factors such as fees and expenses of the fund, transaction costs, sample selection, regulatory restrictions, and timing differences associated with additions to and deletions from the Index.

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.
