Eaton Vance High Income Municipal ETF (EVYM) is an actively managed exchange-traded fund that seeks to provide high current income exempt from regular federal income tax through investments in a diversified portfolio of high yield and investment grade municipal obligations, primarily U.S. municipal debt securities with below investment grade ratings and maturities of ten years or more; the fund employs a disciplined investment process leveraging in-depth research, rigorous risk controls, and strategic asset selection across various municipal sectors and regions to balance yield, credit quality, interest rate sensitivity, and tax efficiency. EVYM operates within the fixed income segment focusing on the municipal bond market, targeting income-oriented investors seeking tax-advantaged returns with managed risk exposure to market volatility, credit events, and liquidity conditions; it features a net expense ratio of 0.39%, daily liquidity via exchange trading, and no underlying index, with portfolio characteristics including effective duration, yield-to-worst, and option-adjusted spread metrics. Launched on February 25, 2025, by Morgan Stanley Investment Management (MSIM) under the Eaton Vance brand following MSIM's acquisition of Eaton Vance, EVYM represents a key expansion of MSIM's active fixed income ETF platform, which grew to over $4.7 billion in assets and now includes eight municipal and high yield strategies; this launch aligns with rising demand for tax-efficient, customizable municipal exposure amid interest rate fluctuations and municipal market opportunities. The fund is advised by Morgan Stanley Investment Management Inc. and distributed by Foreside Fund Services, LLC, with operations centered in the United States and headquarters tied to MSIM's Boston-based Eaton Vance division.
