About FNBGX

Fidelity Long-Term Treasury Bond Index Fund is a mutual fund that seeks to provide a high level of current income by investing primarily in long-term U.S. Treasury bonds. The fund typically allocates at least 80% of its assets to securities included in the Bloomberg U.S. Long Treasury Bond Index, focusing on fixed-income instruments with maturities generally exceeding 10 years. This approach emphasizes government-backed debt, offering exposure to the credit quality and interest rate sensitivity characteristic of long-duration U.S. government securities. With an effective duration close to 15 years and a portfolio yield of around 3.87%, the fund is known for its extensive interest rate sensitivity and relatively low credit risk, given its exclusive focus on U.S. Treasuries. Fidelity Long-Term Treasury Bond Index Fund appeals to investors seeking broad-based access to the long-term U.S. Treasury market, and it is notable for its low expense ratio, cost efficiency, and transparent management style. The fund plays a significant role for those looking to manage interest rate risk, implement liability-driven investment strategies, or gain targeted exposure to long-term government bonds as part of a diversified fixed-income allocation.
