Under normal circumstances, the fund invests at least 80% of its assets in municipal securities, the income from which is exempt from federal income tax. For purposes of this policy, "Assets" means net assets, plus the amount of borrowings for investment purposes. Up to 100% of the fund's assets may be invested in short-term municipal instruments such as variable rate demand notes, short-term municipal notes and tax-exempt commercial paper.

Muni bond ETFs may shine in 2026 as attractive yields, solid credit quality and easing policy risks boost investor appeal.

NEW YORK, March 27, 2026 /PRNewswire/ -- J.P. Morgan Asset Management today announced the upcoming exchange listing transfer of 14 ETFs from their current exchanges including the NASDAQ Stock Market LLC, NYSE Arca, Inc., and Cboe BZX Exchange, Inc. As of the exchange opening on April 16, 2026, the listing exchange for each fund will be changed per the following.

JPMorgan Ultra-Short Municipal Income ETF is an active ETF focusing on short-term muni bonds. It has a tax-advantaged 2.0% yield to maturity. Income is quite low, even after accounting for potential tax advantages. JMST compares unfavorably to several of its peers on most important metrics too. It's a weak fund with a weak investment thesis.

JMST offers low-risk, tax-free income from short-term investment-grade municipal bonds, but yields are notably lower than alternatives. The fund's construction is sound—minimizing interest rate and credit risk—yet its conservative approach results in underwhelming returns. Other short-term muni funds, like SHYM, achieve higher yields by including unrated bonds, which historically have low default rates.

Tariff mayhem continues to cause volatility in markets as investors attempt to make sense of continuous changes. In a tumultuous environment, investors increasingly turned to actively managed bond ETFs this year according to JPMAM research.
