Our read on MUNX
CA Boston bond boutique's muni playbook in an ETF wrapper. GW&K's team picks individual tax-exempt bonds across sectors, maturities and credit tiers, aiming at federally tax-free income instead of mirroring an index.
The Fund seeks current income exempt from federal income tax while preserving capital. Capital appreciation is a secondary objective.
Why people hold it
- Actively run rather than index-shadowing: managers can shift sectors, maturities and credit quality inside a muni market where many bonds trade by appointment.amgetfs.com
- At 0.29% a year, it charges a shade under the typical muni bond ETF while running an active book instead of a rules-based one.
- Clear job description: core intermediate US munis, federally tax-exempt income first, capital preservation alongside it, price appreciation only a secondary goal.amgetfs.com
- Income is designed to arrive monthly per the fund's filings, and the portfolio stays tightly inside that tax-exempt muni mandate with no side bets.
Worth knowing
- Index munis undercut it sharply: VTEB and SCMB charge 0.03%. Active bond selection is the entire reason to pay the difference here.
- Launched in late 2025, so the record is short and trading has been light. Spreads can run wider than the big muni index funds, which makes execution matter.
- Payout timing has been uneven early on, and the exemption is federal only: state taxes and bonds subject to the AMT are still in play.aaii.com
