The First Trust Municipal High Income ETF (FMHI) is an actively managed municipal bond fund that aims to provide high current income exempt from federal taxes. While FMHI offers a higher yield than many peers, it also has greater interest rate sensitivity and lower credit quality in its portfolio, making it a more volatile option. The fund may appeal to high-income investors looking to hold municipal bonds in taxable accounts, but its risks should be carefully considered.

Why it matters

Municipal bond funds like FMHI can provide tax-advantaged income for investors in high tax brackets, but their risk profiles vary. Understanding FMHI's higher duration, lower credit quality, and active management approach is crucial for determining if it fits an investor's needs and risk tolerance.

The details

FMHI invests primarily in a mix of investment-grade and unrated municipal bonds, aiming to maximize tax-exempt income. However, over 50% of its portfolio is in bonds rated below investment-grade as of March 2026. This contrasts with peers like the PIMCO Intermediate Municipal Bond ETF, which is entirely invested in investment-grade munis. FMHI also has a longer duration of 8.55 years, making it more sensitive to interest rate changes than lower-duration municipal bond funds.

  • As of March 31, 2026, FMHI had a weighted average effective duration of 8.55 years.
  • As of April 10, 2026, FMHI had a 4.37% annualized yield.
