The First Trust Flexible Municipal High Income ETF, MFLX_US, is an actively managed strategy providing exposure to United States, Municipal Fixed Income. It is listed on the NASDAQ and has assets under management of $21.1m (as of Aug 31, 2026). The ETF trades in USD and was listed on the exchange on Sep 27, 2016. It has a net expense ratio of 88bps. (All data in USD as of Oct 9, 2026 unless stated.)

The investment process underpinning the actively managed First Trust Flexible Municipal High Income ETF seeks current income by investing ≥80% of net assets in municipal debt whose interest is exempt from regular U.S. federal income tax, spanning general obligation, revenue, lease, pre-refunded/escrow-to-maturity, private-activity, and custodial-receipt structures (USD). The strategy flexes across the muni curve and credit spectrum but emphasizes longer-duration, higher-yielding issues, including below-investment-grade and unrated bonds deemed comparable in quality; up to 10% may be held in defaulted (distressed) securities. Portfolio construction may incorporate inverse floaters via TOB trusts, closed-end funds (≤10%), and taxable municipals (≤20%) when risk-reward is favorable. Derivatives (e.g., U.S. Treasury futures, interest-rate and credit swaps, listed options) are used to manage duration, curve, and credit exposures. Liquidity and investability are monitored with an illiquid-securities cap of 15%; cash creations/redemptions and defensive postures may be employed as needed.

Investment Proposition

First Trust Flexible Municipal High Income ETF (MFLX) targets higher after-tax income by investing actively across the municipal bond market, employing a flexible mandate that can allocate among investment-grade and high-yield issuers, sectors, states, and maturities as relative value shifts. The portfolio management approach emphasizes fundamental credit research, structural analysis, and security selection to balance income generation with risk controls, while actively managing duration, yield-curve positioning, and call features. Outcomes are influenced by municipal credit trends, tax policy, and interest-rate regimes; historically, credit repair and steady growth support spreads, while tightening liquidity or rising defaults can challenge lower-rated segments. In portfolios, MFLX can serve as an income sleeve for taxable investors seeking federally tax-exempt cash flows, a diversification complement to corporate credit, or a tactical allocation when municipal valuations dislocate relative to Treasuries. Likely users include high-bracket households building core tax-aware income ladders and multi-asset managers seeking flexible muni exposure within outcome-oriented models. A key risk to monitor is exposure to lower-rated or thinly traded credits, where liquidity and downgrade cycles can widen spreads and increase price volatility during risk-off episodes.
