- Thornburg Strategic Income Fund Class I Shs (TSIIX) is a mutual fund managed by Thornburg Investment Management, Inc. that seeks a high level of current income with some long-term capital appreciation as a secondary objective; it invests primarily in a broad range of global income-producing debt obligations of any kind, quality, or maturity, including bonds and other debt securities issued by domestic and foreign companies (including high-yield or junk bonds); mortgage-backed securities and other asset-backed securities (including commercial mortgage-backed securities); convertible debt obligations; obligations issued by foreign governments (including emerging markets); collateralized mortgage obligations, collateralized debt obligations, collateralized bond obligations, and collateralized loan obligations; U.S. government and agency obligations; structured notes; zero-coupon bonds and stripped securities; and taxable municipal obligations. The fund employs active management based on issuer and industry analysis, domestic and international economic developments, interest rate outlooks, inflation trends, and securities supply-demand dynamics, while maintaining flexibility to adjust holdings for income enhancement, risk reduction, or portfolio optimization; it targets institutions, financial advisors, and investors worldwide through share classes including Class I (TSIIX, with a net expense ratio of 0.60% after waivers through at least February 1, 2026), Class A (TSIAX), and Class C (TSICX). Launched on December 18, 2007, the fund is headquartered in Santa Fe, New Mexico, and operates globally with portfolio managers Lon Erickson (since 2015), Ali Hassan (since 2021), and Christian Hoffmann (since 2018); as of October 31, 2025, it held net assets with a portfolio turnover of around 60%, effective duration reflecting multisector bond characteristics, and a Morningstar rating of 4 stars over 5- and 10-year periods among multisector bond peers. Recent developments include a contractual fee waiver and expense reimbursement by Thornburg to cap Class I expenses at 0.60% through February 1, 2026 (with potential recoupment in the same fiscal year); removal of the blended secondary benchmark (80% Bloomberg U.S. Aggregate/20% MSCI World) effective September 30, 2024, in favor of the Bloomberg U.S. Universal Index; continued monthly distributions with a trailing 12-month yield of 5.44% and increasing payouts for two consecutive years through 2024; and strong risk-adjusted performance ranking in the top 11% of mutual funds as of mid-2025, with year-to-date returns of 2.59% amid volatile fixed-income markets.
