Our read on each fund

ETF.net Research

MUBAiShares National Muni Bond ETF

WTMUBWisdomTree Core Laddered Municipal Fund

In short

MUB Municipal bonds, indexed and cheap. Since 2007, MUB has packaged investment-grade national munis into tax-exempt monthly income for five basis points a year, and it sits among the deepest pools in the muni-ETF aisle.

WTMU No data

Stated mandate

MUB The fund seeks to track an index of investment-grade U.S. municipal bonds, providing diversified exposure to the national municipal-bond market and tax-exempt income.

WTMU No data

Why people hold it

  • MUB 0.05% a year against a muni-ETF median near 0.30%. In a category built on modest, tax-exempt yields, that fee gap is real money left in the fund.
  • The benchmark is AMT-free: the ICE AMT-Free US National Municipal Index screens out munis whose interest can be pulled into the alternative minimum tax.ishares.com
  • Tracks its index closely, one of the tighter jobs in its peer group, and distributes monthly. A multi-billion-dollar fund that trades actively.
  • Broad investment-grade exposure across the national muni market, spread over thousands of issuers rather than one state's budget.ishares.com

WTMU No data

Worth knowing

  • MUB Two rivals undercut it: VTEB and SCMB both run 0.03%. A two-basis-point gap is small, but it is a gap.
  • A bond fund with no maturity date to hold to. Share prices move with interest rates and muni credit conditions, both directions.
  • National by design, so no single-state tilt and no in-state tax angle. iShares runs state-specific muni funds such as NYF for that job.
