About FUMBX

Fidelity Short-Term Treasury Bond Index Fund is an open-end mutual fund that seeks to track the performance of a market-weighted index of U.S. Treasury securities with maturities typically between one and five years. It aims to provide broad, low-cost exposure to short-duration U.S. government debt, emphasizing high credit quality and limited interest-rate sensitivity. The portfolio holds a diversified basket of U.S. Treasury notes and bonds, resulting in minimal credit risk and a duration profile designed to dampen volatility relative to intermediate and long-term bond strategies. Positioned within the Short Government category, the fund’s structure and mandate make it a tool for liquidity management, core fixed income allocation, and cash segmentation for investors who require principal stability with income from Treasury yields. Its index-tracking approach, low expense profile, and concentration in U.S. Treasuries support efficient implementation of defensive or rate-sensitive views while providing a transparent link to the short end of the Treasury curve. By focusing exclusively on government-backed securities, the fund plays a stabilizing role within diversified portfolios and complements risk-bearing assets.
