Invesco Municipal Strategic Income ETF (IMSI) is an actively managed exchange-traded fund that seeks current income exempt from federal income tax by investing at least 80% of its net assets in municipal securities exempt from federal income taxes and other instruments with similar economic characteristics; the fund normally maintains a weighted average portfolio duration of less than 7.5 years. Its portfolio emphasizes a mix of investment-grade and high-yield municipal bonds across various maturities, with top holdings including New York Transportation Development Corp revenue bonds, Virginia Beach Development Authority obligations, and California Community Choice Financing Authority securities; credit quality allocations feature significant exposure to A, BBB, and not-rated categories, alongside cash equivalents. IMSI targets investors seeking tax-exempt income from U.S. municipal issuers, including state and local governments, transportation authorities, and development agencies, with geographic operations focused on the United States.
Launched on December 9, 2022, the ETF trades on the Cboe BZX Exchange under the ticker IMSI and is issued by Invesco Ltd., a global asset manager founded in 1935 and headquartered in Atlanta, Georgia. Invesco Ltd. oversees a broad range of ETFs and mutual funds, with IMSI forming part of its fixed-income offerings that leverage active management expertise in municipal markets.
Effective after the close of business on February 24, 2025, IMSI undergoes a significant strategic shift by reorienting at least 80% of its total assets toward low- to medium-quality municipal securities; concurrent with this change, the fund's name converts to Invesco Rochester High Yield Municipal ETF and its ticker symbol updates to IROC. This repositioning enhances focus on higher-yielding, riskier municipal bonds while preserving the duration target, aligning with evolving market demands for tax-efficient high-yield strategies. The transition reflects Invesco's ongoing product evolution amid broader firm initiatives, including new active ETF launches in fixed income and private markets partnerships, such as the April 2025 repurchase agreement and strategic alliance with MassMutual and Barings.
