What this fund is
Objective, as filed

Fidelity ZERO Total Market Index Fund seeks to provide investment results that correspond to the total return of a broad range of U.S. stocks.

Strategy, summarised

The fund tracks the Fidelity U.S. Total Investable Market Index using statistical sampling techniques, holding a representative cross-section of large-, mid-, and small-capitalization U.S. stocks weighted by float-adjusted market capitalization. Because the fund samples rather than holds all index constituents, its returns may diverge from the index.

Volatility over the last 12 months: 12.91%. Past returns are a record, not a forecast.

Jun 2026 and Jul 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
