About FSMAX

The Fidelity Extended Market Index Fund is a mutual fund designed to track the performance of the Dow Jones U.S. Completion Total Stock Market Index, which broadly represents the mid- and small-cap segment of the U.S. equity market. Unlike large-cap-focused funds, this fund invests in thousands of companies excluding those in the S&P 500, providing diversified exposure to sectors and industries driven by mid-sized and smaller firms. Its primary role is to complement large-cap holdings, offering investors a way to capture growth from less prominent but dynamic parts of the market. The fund features an extremely low expense ratio and low turnover, emphasizing cost efficiency and tax effectiveness. With a portfolio encompassing over 3,500 holdings and minimal concentration in its top positions, it serves as a key diversifier for portfolios seeking broader participation in U.S. equity growth outside the largest corporations. Since its inception in 1997, the fund has been recognized for its disciplined index-tracking approach and its significance as a core building block for asset allocation strategies focused on total market coverage.
