Fidelity Short Duration High Income Fund (FSAHX) is an open-end mutual fund managed by Fidelity Management & Research Company LLC that seeks a high level of current income with a secondary objective of capital appreciation; it normally invests primarily in income-producing debt securities, preferred stocks, and convertible securities, with an emphasis on lower-quality debt securities rated BB or B by Standard & Poor's or Ba or B by Moody's Investors Service (or comparably rated by another nationally recognized credit rating agency, or unrated but considered of comparable quality by Fidelity); the fund normally maintains a dollar-weighted average duration of three years or less. Core holdings include high-yield corporate bonds such as TransDigm Inc. 6.75%, Tenet Healthcare Corp. 5.125%, EG Global Finance PLC 12%, and EchoStar Corp. 10.75%, alongside allocations to Fidelity Cash Central Fund for liquidity; the expense ratio stands at 0.75%, and the fund targets individual and institutional investors seeking income from short-duration high-yield instruments. Launched on November 5, 2013, the fund operates from Fidelity's headquarters in Boston, Massachusetts, with global exposure through its portfolio of fixed-income securities primarily denominated in U.S. dollars but issued by domestic and international entities across various industries including healthcare, aerospace, telecommunications, and energy. In recent developments, the fund has sustained steady monthly dividend distributions, increasing its trailing twelve-month yield to 6.56% with an annual payout of $0.58 per share as of mid-2025, reflecting three consecutive years of distribution growth amid favorable high-yield market conditions; portfolio performance showed resilience with year-to-date returns of 0.88% and one-year total returns of 6.94% through mid-2025, supported by active management that maintained a risk-adjusted Sharpe ratio ranking in the top 6% of mutual funds. No major acquisitions, mergers, or strategic reorganizations have been reported in the last 1-2 years, with ongoing focus on credit quality diversification within the BB/B rating spectrum and duration control to mitigate interest rate sensitivity.
