MYMFDState Street My2026 Municipal Bond ETF

In short

IBMO No data

MYMF A muni fund with an expiration date. MYMF holds bonds maturing in 2026, pays monthly, then hands back remaining principal on or about December 15, 2026. And a manager picks the bonds, not an index.

Stated mandate

IBMO No data

MYMF The fund is an actively managed target-maturity municipal bond strategy focused primarily on bonds maturing in 2026. It is designed to distribute remaining principal and liquidate around December 15, 2026.

Why people hold it

IBMO No data

  • MYMF Maturity is written into the product: the fund is designed to distribute any remaining principal and liquidate on or about December 15, 2026.ssga.com
  • Actively managed in a corner of the market built on index ladders: top-down risk positioning plus bottom-up research on sectors and issuers.ssga.com
  • Monthly payouts from a compact book of roughly 70 munis, with income the fund seeks to keep exempt from regular federal income taxes.ssga.com
  • One rung in State Street's MyIncome suite, a family of target-maturity funds meant to be stacked into a custom bond ladder.ssga.com

Worth knowing

IBMO No data

  • MYMF Costs 0.20% a year: above the 0.18% cohort median and double the 0.10% on iBonds muni rungs like IBMO, which also targets a 2026 maturity.
  • A small, thinly traded fund, the setup where bid/ask spreads tend to run wider than in the category's largest names.
  • Launched in 2024 and built to wind up in 2026, so both the track record and the remaining life are short by design.
