Our read on JMST

ETF.net Research

AMunis without the long-end drama. JMST holds investment-grade municipal bonds with an average weighted maturity of two years or less and pays federally tax-exempt income monthly, for 0.18% a year.

Stated mandate

The fund seeks current income exempt from federal income tax while maintaining stability of principal. It primarily invests in investment-grade fixed-, variable-, and floating-rate municipal securities and seeks an average weighted maturity of two years or less.

Why people hold it

  1. 010.18% a year, well under the 0.30% median for its muni cohort.
  2. 02The mandate targets an average weighted maturity of two years or less, so rate moves hit it far less than they hit long-dated muni funds.am.jpmorgan.com
  3. 03Roughly 1,600 investment-grade positions across fixed, variable and floating rate munis, so no single issuer carries the fund.
  4. 04A multi-billion-dollar fund that trades actively, which generally keeps the spread you pay to get in and out narrow.

Worth knowing

  1. 01Broad muni index funds go cheaper: VTEB and SCMB run 0.03%, MUB 0.05%. You are paying up for the ultra-short mandate.
  2. 02Short maturities cut rate risk, and they cut the extra income longer municipal bonds pay for carrying that risk. This is a stability-of-principal design.
  3. 03The stated exemption is from federal income tax. State and local treatment is a separate question that depends on where you file.
