About FMSFX

Fidelity Mortgage Securities Fund is an open-end mutual fund focused on delivering a high level of current income through investment in mortgage-related securities. The fund primarily allocates at least 80% of its assets to investment-grade mortgage-backed securities—such as those issued by government-sponsored enterprises like the Federal National Mortgage Association (Fannie Mae) and the Government National Mortgage Association (Ginnie Mae)—and related instruments, including repurchase agreements. This approach provides exposure to the U.S. housing and real estate finance sector, with the fund positioned within the intermediate core bond category, offering both moderate credit quality and interest rate sensitivity. Key features of the fund include a diversified portfolio of securitized mortgage assets, a below-average distribution fee structure, and a focus on prudent risk management. With an effective duration of approximately 5.8 years and a recent yield in the mid-3% range, it aims to balance income generation and risk for investors seeking stability from fixed income investments. The fund does not emphasize equity holdings, and its portfolio is heavily weighted toward mortgage-backed debt securities, underlining its specialized role in the broader fixed income landscape.
