FUMB vs VTES

FUMBCFirst Trust Ultra Short Duration Municipal ETF

VTESAVanguard Short-Term Tax-Exempt Bond ETF

In short

FUMB Active ultra-short munis with a filter: First Trust's managers hand-pick bonds that fund basic infrastructure and essential local services, and keep portfolio duration under a year. Federally tax-exempt income, paid monthly, for 0.45%.

VTES Vanguard's muni ETF on a short leash: an AMT-free tax-exempt index, but capped at seven years to trim interest-rate sensitivity. Five basis points, roughly 2,700 bonds, income paid monthly.

Stated mandate

FUMB FUMB seeks federally tax-exempt income while preserving capital. Normally, it invests at least 80% of net assets in municipal debt securities whose interest is exempt from regular federal income tax.

VTES The Fund seeks to track an index representing investment-grade U.S. municipal bonds with remaining maturities from one month through seven years.

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

• VTES Costs 0.05% a year, a fraction of what the typical muni-bond fund in its category charges. One of the cheapest ways into tax-exempt bonds.
• Maturities run one month to seven years, so the portfolio moves less on rate swings than long-dated muni funds. Short duration is the whole point here.vanguard.com
• The index is AMT-free national investment-grade munis, so interest is federally tax-exempt and not caught by the alternative minimum tax.vanguard.com
• Roughly 2,700 bonds via index sampling, run by Vanguard's fixed income group, with distributions paid monthly. It tracks its benchmark closely.vanguard.com

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.

• VTES Short maturities cut both ways. Vanguard's own materials describe moderate current income, the trade-off for less rate sensitivity than longer muni portfolios.vanguard.com
• It's a national fund, so it isn't structured to shelter state income tax the way single-state muni ETFs such as NYF are.
• Launched in 2023, it has a shorter live record than muni ETFs that have been trading for over a decade, including its broader sibling VTEB.
