Fund profile

As filed in the prospectus · 2025 Q4

Fidelity ZERO Extended Market Index Fund seeks to provide investment results that correspond to the total return of stocks of mid- to small-capitalization U.S. companies.

Strategy · summarised

The fund tracks the Fidelity U.S. Extended Investable Market Index, which comprises mid- and small-capitalization U.S. stocks excluding the 500 largest companies, using statistical sampling techniques to replicate index returns based on factors including capitalization, industry, valuation ratios, and dividend yield. Because the fund samples rather than holds all index constituents, its returns may diverge from the index.
