AB Short Duration Income ETF (SDFI) is an actively managed exchange-traded fund that seeks to provide current income consistent with capital preservation by investing primarily in a diversified portfolio of short-duration, investment-grade fixed income securities. The fund's core holdings include U.S. Treasury securities, corporate bonds, asset-backed securities, and commercial paper with maturities typically under three years; it employs a multi-sector approach emphasizing high-quality debt instruments from issuers across financials, industrials, and utilities sectors. SDFI targets income-seeking investors such as retirees and institutions requiring low-volatility fixed income exposure, with operations focused on the U.S. market and benchmarked against short-term bond indices like the Bloomberg U.S. 1-3 Year Treasury Index.
Launched in 2023 and domiciled in the United States under the management of AllianceBernstein, the ETF recently expanded its investment strategy in late 2024 to incorporate a modest allocation to high-yield short-duration bonds amid favorable yield curves, enhancing income potential without significantly increasing duration risk. In Q3 2025, SDFI announced a strategic partnership with a leading ESG analytics provider to integrate sustainability screens into its security selection process, reflecting growing demand for responsible investing in short-duration products. The fund also benefited from a $150 million seed capital infusion from institutional investors in early 2025, supporting assets under management growth to over $500 million.
