Fidelity High Income Fund (SPHIX) is an open-end mutual fund managed by Fidelity Management & Research Company LLC, a subsidiary of FMR LLC, that seeks a high level of current income with capital appreciation as a secondary objective. The fund invests primarily in high-yield, lower-rated fixed-income securities, including non-investment grade debt obligations such as corporate bonds, debentures, notes, and commercial paper of domestic and foreign issuers; U.S. government obligations and repurchase agreements; mortgage- and other asset-backed securities; inflation-protected securities; real estate-related securities; money market instruments; and other investment companies including exchange-traded funds. It may also engage in foreign currency transactions, use derivatives like futures, options, and swaps, and employ leverage through borrowing; the portfolio emphasizes securities rated below investment grade (BB/Ba or lower) or unrated securities of comparable quality, with up to 20% in emerging market debt and no maturity or duration restrictions.
Established in 1987 and domiciled in the United States with administrative operations in Boston, Massachusetts, the fund targets income-oriented investors including individuals, institutions, and financial advisors across domestic and international markets through various share classes (Class A, C, I, etc.) offered via broker-dealers, retirement plans, and direct channels.
Recent developments include a strategic shift in 2023 toward enhanced portfolio diversification with increased allocations to opportunistic high-yield sectors amid rising interest rates; in late 2024, Fidelity announced portfolio manager transitions to bolster expertise in distressed debt amid economic volatility; the fund participated in a 2025 Fidelity-wide initiative for sustainable high-income strategies incorporating ESG screening overlays without altering core yield focus; additionally, it benefited from parent company FMR LLC's acquisition of a boutique fixed-income analytics firm in Q1 2025 to improve risk modeling for non-investment grade holdings.
