F/m Ultrashort Tax-Free Municipal ETF (ZMUN)

F/m Ultrashort Tax-Free Municipal ETF is a fixed income fund from F/m Investments that invests in short-maturity municipal securities issued by U.S. states, cities and other local government entities. Its goal is to provide current income that is generally exempt from federal income tax while keeping interest-rate sensitivity very low.

By concentrating on municipal debt with very short maturities or frequent rate resets, the fund aims for limited price fluctuation and is often used as a tax-aware alternative to cash or money market holdings. It trades on NASDAQ under the ticker ZMUN.
