Fidelity Municipal Bond Opportunities ETF (FMUB)

Fidelity Municipal Bond Opportunities ETF (FMUB) is an actively managed exchange-traded fund from Fidelity Investments, launched in 2025. It seeks income that is exempt from federal income tax.

The fund invests in municipal bonds issued by U.S. states, cities and other public entities and can hold securities of any maturity and credit quality. This flexibility allows the managers to pursue opportunities across the municipal market, including lower-rated and longer-dated bonds, based on Fidelity's credit research and relative value analysis.

As an active fund, it does not track an index and adjusts its sector, state and maturity exposures as conditions change. The fund is listed on Nasdaq.
