State Street Fixed Income Sector Rotation ETF (FISR) is an actively managed exchange-traded fund that seeks total return by tactically allocating among income- and yield-generating fixed income exchange-traded funds (ETFs) affiliated with State Street Global Advisors. The fund invests at least 80% of its net assets directly or indirectly in other SPDR ETFs covering fixed income sectors, including intermediate-term Treasury bonds (such as SPDR Portfolio Intermediate Term Treasury ETF), mortgage-backed securities (SPDR Portfolio Mortgage Backed Bond ETF), long-term Treasury bonds (SPDR Portfolio Long Term Treasury ETF), corporate bonds (SPDR Portfolio Long Term Corporate Bond ETF and SPDR Portfolio Intermediate Term Corporate Bond ETF), high yield bonds (SPDR Bloomberg High Yield Bond ETF), and short-term T-bills (SPDR Bloomberg 1-3 Month T-Bill ETF); it employs a proprietary sector selection model incorporating macroeconomic, financial, and market data to forecast returns and overweight favorable sectors while underweighting others, with rebalancing occurring 12-15 times per year. FISR, with assets under management of approximately $282 million, a gross expense ratio of 0.50%, and a dividend yield around 3.87% to 4.17%, primarily targets investors seeking broad credit fixed income exposure in the intermediate core bond category, with geographic focus on U.S. fixed income markets. Launched on April 2, 2019 and sponsored by State Street Global Advisors, a Boston-based division of State Street Corporation founded in 1978, the ETF operates without noted subsidiaries or parent fund relationships beyond its SPDR ETF holdings. In recent developments, State Street Global Advisors has expanded its ETF proxy voting program significantly as of Q1 2025, with over 25 U.S. ETFs and mutual funds joining (a 63% increase), more than 60 institutional clients representing 12% of institutional AUM enrolled, and over 146,000 new retail investors in European SPDR ETFs; additionally, SSGA issued its 2025 Global Market Outlook emphasizing favorable fixed income conditions amid expected rate cuts and U.S. soft landing, alongside ongoing enhancements to fixed income ETF offerings like tactical allocations in FISR. No major acquisitions, funding rounds, or structural changes specific to FISR have been reported in the last 1-2 years.
