MFS Active Short Duration Income ETF is an actively managed exchange-traded fund sponsored by MFS Investment Management that seeks total return with an emphasis on current income through investment in short-duration fixed income securities, including high-quality corporate bonds and structured debt; the fund is designed to maintain a dollar-weighted average duration broadly comparable to the Bloomberg 1-5 Year Government/Credit Bond Index, plus or minus one year. MFS Investment Management, founded in 1924 and headquartered at 111 Huntington Avenue, Boston, Massachusetts, is a global investment manager serving financial advisors, intermediaries, institutions, and individual investors through active equity, fixed income, and multi-asset strategies, and operates from offices in North America, Europe, and Asia-Pacific.
In 2026, MFS expanded its ETF platform with the launch of MFS Active Short Duration Income ETF and the related MFS Active Short Muni Bond ETF, representing a strategic extension of its active fixed income lineup into exchange-traded funds; SEC filings for the new ETF complex also appeared in mid-2026 before the September 2026 launch. The fund is part of MFS Active Exchange Traded Funds Trust, and MFS’s broader product set includes mutual funds, institutional mandates, separately managed accounts, and retirement-focused investment solutions.
