What Does FSMAX Do?

Fidelity Extended Market Index Fund (FSMAX) is an index fund managed by Fidelity Investments. The fund's primary objective is to replicate the performance of the Dow Jones U.S. Completion Total Stock Market Index, which represents the performance of stocks of mid- to small-capitalization U.S. companies not included in the S&P 500.

FSMAX offers investors diversification across a wide range of sectors and industries within the U.S. economy. By focusing on mid- and small-cap companies, the fund provides exposure to a segment of the market that may offer higher growth potential compared to large-cap stocks. As of 2026, FSMAX has grown into a substantial fund with a market cap of $40.95 billion, reflecting its popularity among investors seeking broad market exposure.
