Why people hold it

• FUMB Built to sit at the very short end: the prospectus targets a weighted average duration of less than one year, the lever that governs how much a bond portfolio's price moves when rates move.sec.gov
• The selection screen is unusual for a park-your-cash fund: munis that meet basic infrastructure needs or critical community services, across at least 10 states, tilted toward growing populations and healthy employment.sec.gov
• Roughly 300 muni positions, with interest exempt from regular federal income tax, distributed monthly rather than quarterly.
• No index to copy. A human team picks the bonds and has run this mandate since the 2018 launch, which is early for an ultra-short muni ETF.sec.gov

Worth knowing

• FUMB 0.45% sits above the category median and well above index-run neighbors: VTES at 0.05%, SUB at 0.07%, GUMI at 0.16%. Active credit research is what the gap buys.
• Tax-exempt here means regular federal income tax. It is not automatically exempt from your state's income tax.
• A few-hundred-million-dollar fund that trades moderately, not one of the category's liquidity giants, so bid-ask spreads carry more weight on entry and exit.
