JPMorgan Ultra-Short Municipal Income ETF JMST

JPMorgan Ultra-Short Municipal Income’s veteran managers, strong fundamental research, and specialized market expertise make for a compelling tax-exempt ultrashort strategy.

Veteran managers Curtis White and Josh Brunner each bring around three decades of industry experience to this strategy. White’s money market expertise, combined with Brunner’s credit focus, creates a strong backing for their approach to set them apart among peers. Given the constant maturing of bonds and the dynamic nature of the ultrashort space, the managers emphasize relative value calls to help identify attractive bonds in the market to keep the portfolio invested. The managers leverage fundamental credit research from a 12-person municipal analyst team that averages 15 years of experience to inform their picks. The analysts provide valuable fundamental research and relative valuation analysis, as well as keeping the managers updated on upcoming new issues. White and Brunner’s extensive knowledge of the short end of the municipal yield curve, combined with the well-resourced research team, ensures this exchange-traded fund stays ahead of new opportunities in this market.

The fund keeps its average duration under a year for its ultrashort mandate. However, it sits within the muni national short Morningstar Category, which typically houses strategies with average durations of about 2-3 years. Shorter duration results in less volatility and upside potential for this strategy than its category peers, but the fund is suitable for investors looking for a step out from a money market fund. The fund keeps most of its assets in investment-grade bonds, though the managers invest in nonrated securities for a slight yield pickup.

Despite being an unusual fit among longer-dated peers, the fund has delivered a solid track record. It outpaced both its median peer and the category benchmark, the Bloomberg Municipal 3 Year 2-4 Index, between its November 2018 inception and December 2025 with lower volatility. This fund has and should continue to excel in stressful markets, particularly rising rate environments such as in 2022. It might fall behind when rates fall, though its relative value focus should help it keep up in unfavorable markets.

This strategy balances liquidity with additional yield from security selection and relative value calls; it earns an Above Average Process rating.

The managers leverage decades of market expertise, a large bench of experienced credit analysts, and consistent execution to deliver a portfolio with incrementally more risk and reward than a money market fund. Their valuation-focused approach, informed by sound fundamental credit research, and focus on short munis, help the team stay nimble in this dynamic market. The strategy targets an average duration of less than 1 year and keeps most of its portfolio in bonds with matching duration (a measure of interest rate risk). However, the managers can scoop up bonds further out on the yield curve when they provide attractive yields. They can also invest up to 20% in nonrated bonds for additional yield; such bonds are typically short-term notes from investment-grade issuers.

The fast-paced nature of the ultrashort space requires the managers to navigate among available offerings on the market rather than taking intentional sector tilts. A large and experienced analyst team helps them stay ahead of new issues and changing market conditions. Their in-depth credit research and valuations calls are a crucial part of the security selection process.

Liquidity is key for this ultrashort offering. The fund often maintains around 20%-30% of its portfolio in cash, variable rate demand notes, and bonds maturing within two weeks. White and Brunner adeptly navigate a mix of maturing fixed-rate bonds as well as floating-rate securities in the portfolio to maintain the desired liquidity profile. The managers draw on insights from J.P. Morgan’s broader fixed income team to thoroughly evaluate the underlying guarantors on the VRDNs they own, cutting through these securities’ more opaque structure.

Trading is another important edge. J.P. Morgan’s proprietary tools scrub offerings and bid lists across the municipal market and aggregate them into a trading platform with baked-in fundamental credit research observations. The managers have opportunistically traded odd-lots (less than USD 100,000 par value) when their bid-ask spreads are attractive, though this is not the norm.

The fund’s ultrashort mandate sets it apart in the muni national short category. Its average duration of less than 1 year is significantly shorter than its typical category peer, which has a duration of around 2-3 years. Nonetheless, the fund has delivered on its mandate to act as an alternative to money market funds, with the potential to outperform cash. As of December 2025, its 2.8% trailing 12-month yield was competitive with the median of its category peers, which have substantially longer durations.

The fund can own up to 10% in below-investment-grade bonds, though in practice it has around 1 percentage point at most in these securities. Instead, the managers typically prefer to invest in nonrated short-term notes from high-quality issuers for the yield pickup. As of December 2025, these securities accounted for around 10% of assets. While Curtis White and Josh Brunner dynamically manage this allocation, they typically do not park more than 20% of the portfolio here.

The managers also seek attractive relative value across various muni sectors. Though they are more reactive to available opportunities in the market than intentional sector tilts, the team still leverages sector views from the broader municipal bond group. They were tilted more toward attractive names in the hospital sector in recent months while treading lightly on local general-obligation bonds.

A duo of veteran managers leverages specialized expertise, a strong municipal credit research team, and J.P. Morgan’s deep supporting resources to manage this dynamic portfolio. They earn an Above Average People rating.

Comanagers Curtis White and Josh Brunner bring around three decades of industry experience each to this strategy. White’s extensive experience managing money market products and deep knowledge of the short-term municipal market set the team apart. Brunner’s focus on the credit side rounds out the process and helps them carve out an edge in this lower-risk corner of the market. Both managers invest in the strategy, aligning their interests with those of investors.

Given the dynamic nature of this market segment and the constant maturing of bonds in the portfolio, the managers actively adjust the fund’s holdings daily and seek to identify bonds with attractive valuations from available opportunities in the market. They handle a lot of the trading themselves, though recent additions of dedicated municipal traders have helped lighten their workload.

The managers also draw on a large bench of 12 dedicated municipal research analysts, averaging 15 years of industry experience, a great source of strength for this strategy. The research team has made several welcome improvements recently. This includes realigning their coverage structure along the strategies' risk budget and adding quantitative tools to streamline analysts’ workflows. While the roster went through some recent turnover, they have multiple pillars of strength and have had little issue backfilling departures with experienced career analysts.

J.P. Morgan continues to build a track record of strong stewardship, supporting a Parent rating upgrade to High from Above Average.

With more than USD 4 trillion in assets under management (including USD 1.3 trillion in money market funds) and a broad reach, J.P. Morgan is among the largest active asset managers in the US, Europe, and Asia. Although some multi-asset offerings have struggled over the past five years, prompting new leadership to make changes to investment teams, its equity and fixed-income teams boast long-tenured portfolio managers who practice repeatable investment processes that have generally produced strong long-term results. Most of its funds are core building blocks with long lifetimes, though its lineup around the world also includes more-specialized options: Two options-based equity-income exchange-traded funds, launched in 2020 and 2022, are now among the firm’s largest. J.P. Morgan has been an early mover in offering active ETFs, having converted 12 of its open-end mutual funds to the structure and launching others. It isn’t always at the forefront of emerging trends. While it has filed registration statements with the Securities and Exchange Commission for an interval fund and an ETF investing in private markets, it hasn’t yet introduced such an option for all investors, whether on its own or in partnership with another asset manager, unlike some of its closest competitors.

To support the firm’s diverse investment offerings, J.P. Morgan has invested heavily in both portfolio management tools and its client organization. Over the past 10 years, the firm has developed robust proprietary technology with advanced analytics and broad buy-in from investment analysts, portfolio traders, and portfolio managers, all of whom have easy access to the platform. The firm also stands apart for its demonstrated commitment to clients. In the early 2000s, J.P. Morgan began pivoting its engagement with financial advisors to adopt a more consultative approach, supported by its sought-after Guide to the Markets research series that focuses on investor education, not product pitches. This perspective can help clients stay the course, supporting positive investor outcomes.

Incentives reinforce alignment with fundholders. Beginning more than 10 years ago, investment team compensation is tied to three-, five-, and 10-year performance, and portfolio managers must invest at least half of their deferred compensation in J.P. Morgan strategies. Many firms encourage portfolio managers to invest alongside fundholders, but J.P. Morgan goes a step further in requiring client-facing individuals to invest substantial portions of their incentive compensation in the funds.

Although some funds still face high cost hurdles, more than half of share classes charge competitive fees relative to peers.

Despite its unique fit within the muni national short category, the fund beat both the category index and peer median from its 2018 inception through December 2025 with lower volatility. It held up even better compared with a subset of ultrashort category peers with average durations of less than a year. It earned a top quintile in this custom peer group ranking over this period.

While not enough to erase its since-inception outperformance, falling yields and tight credit spreads in 2025 have proved challenging for this fund. The fund lagged the category index, the Bloomberg Municipal 3 Year 2-4 Index, by 80 basis points over the full year, though it still ranked in the better-performing half of its category.

The fund might have difficulties against longer-dated peers in its category during bond market rallies or falling rate environments given its muted credit and duration profile. It trailed the category index by 1.2 percentage points between May and September 2024 when the Fed lowered interest rates, for instance.

Nonetheless, its liquidity mandate shines during stressful markets, such as in the 2022 rate-driven meltdown. It preserved capital and delivered a positive 0.15% return, while the category index fell by 3.4% and half of its category peers were in the red. It similarly outpaced the category index and average peer during the market volatility in early April 2025. The fund’s standard deviation of returns from its 2018 inception through December 2025 ranked in the bottom quintile of its category peers.

JPMorgan Ultra-Short Municipal Inc ETF's Prospectus Adjusted Expense Ratio is 0.18% per year. It places it in the cheapest quintile of the Morningstar US Fund Muni National Short Category, where the median fee is 0.44% per year. This cost positioning translates into a Medalist Rating Price Score of 2.16, which reflects its relative price positioning within the category. The Price Score ranges from -2.50 (most expensive) to +2.50 (cheapest), with higher scores indicating better cost competitiveness.
