Fidelity Extended Market Index Fund seeks to provide investment results that correspond to the total return of stocks of mid- to small-capitalization United States companies.
The fund tracks the Dow Jones U.S. Completion Total Stock Market Index, which covers approximately 4,500 mid- to small-capitalization U.S. stocks, using statistical sampling techniques that weight holdings by market capitalization and match factors such as industry exposure, valuation ratios, and dividend yield. Because the fund samples rather than holds all index constituents, its returns may diverge from the index.

What the fund is made of
Percentages are of fund net assets. Rounding, liabilities and short positions can make totals differ from 100%.
| Stocks | 99.88% |
| Cash & short-term | 5.54% |
| Bonds | 0.01% |
| Derivatives | 0.01% |
These positions come to 105.44% of the fund's net assets. This counts only what the fund reported holding — the holdings disclosure covers assets, not liabilities such as borrowings — so it is not expected to reconcile to 100%.
Derivatives are shown at market value, not notional exposure.
