First Trust Municipal High Income ETF (FMHI)

The First Trust Municipal High Income ETF (ticker FMHI) is an exchange-traded fund holding tax-exempt municipal bonds selected for their yield potential, weighted toward higher-coupon and longer-maturity issues across diverse municipal issuers and sectors.

The high-income tilt

Municipal bonds span a wide yield spectrum: some carry very low yields (typically AAA-rated general obligations issued by strong-credit states and cities); others offer substantially higher yields, reflecting longer maturity, lower credit quality within the investment-grade spectrum, or specific sector risk. FMHI tilts toward the latter part of that spectrum. Rather than holding an equal-weight sample of the municipal market, the fund overweights bonds offering higher current yield. This might include longer-duration bonds, higher-yielding sectors such as housing finance or transportation authorities, or credits with lower-but-still-investment-grade ratings. The goal is to maximize the after-tax yield advantage that municipal bonds offer to high-bracket investors.

Sector composition and diversification

The fund’s portfolio is diversified across major municipal sectors. General obligation bonds issued by states and cities make up a core holding, providing broad-based credit exposure. Education bonds (issued to finance school buildings and university facilities) are typically a meaningful slice. Housing-finance bonds, issued by housing authorities to fund affordable or mixed-income residential development, carry their own credit profile and sector dynamics. Transportation bonds, issued by transit authorities and toll-road authorities, depend on traffic patterns and user fees for repayment. Utility bonds (issued by state and local utility authorities) carry revenue tied to water, sewer, or power sales. Healthcare facility bonds (for hospitals and clinics) depend on institutional credit quality. Smaller sectors such as airport, seaport, and sports-facility bonds round out the mix.

Each sector carries its own risks and opportunities. An investor studying FMHI should understand which sectors dominate the current holdings and how their credit outlook has shifted. A credit stress in housing or transportation would disproportionately affect a fund heavily weighted to those sectors.

Credit quality and the yield-quality tradeoff

Although FMHI targets higher yield, it maintains an overall investment-grade orientation, meaning most holdings carry ratings in the A, BBB, or BAA range rather than speculative-grade or unrated bonds. This is not the same as saying the fund is conservatively positioned — within investment-grade, there is a wide credit quality spectrum, and FMHI’s focus on higher yields means it accepts credit risk that the safest AAA municipal funds do not. The fund’s average credit rating (often published on the fact sheet) is a key metric: a portfolio with an average rating of A is considerably safer than one with an average rating of BBB.

Credit selection and monitoring matter in a fund like this. The manager must assess which higher-yielding credits are offering fair compensation for their risks and which are yield traps — bonds offering high coupons because their credit is genuinely deteriorating. For investors, understanding the current credit composition and the manager’s approach to credit vetting is essential.

Duration, rates, and price sensitivity

FMHI is typically an intermediate-to-longer-duration fund because higher-yielding bonds often have longer maturities. This means the fund is more sensitive to interest-rate moves than a shorter-duration muni fund. When the Federal Reserve is raising rates or long-term rates are rising in the market, FMHI’s share price can fall meaningfully. An investor who bought the fund at a peak share price and is forced to sell during a rising-rate environment may realize losses. Conversely, a falling-rate environment can drive significant appreciation for the fund’s holdings and share price.

The prospectus and fact sheet disclose the fund’s weighted-average maturity and duration; these metrics are crucial for sizing the interest-rate risk appropriate to an investor’s horizon and risk tolerance.

Tax considerations and income distribution

The appeal of FMHI for most investors is the tax-exempt status of its income distributions. Interest payments from the fund’s municipal-bond holdings flow through to unitholders tax-free at the federal level. Many distributions are also free from state and local tax if the investor resides in the state that issued the bonds; this depends on the fund’s specific geographic allocation. For investors in high federal tax brackets or high-tax states, the after-tax yield of FMHI can substantially exceed that of a comparably yielding taxable bond fund.

That said, not all distributions are tax-exempt. If FMHI realizes capital gains (from selling bonds at a profit), those gains are taxable to shareholders. Additionally, any income derived from bonds issued for private purposes (bonds financing private, not public, facilities) may be subject to the alternative minimum tax — a significant consideration for high-net-worth individuals.

Liquidity and trading

FMHI trades on an exchange with daily pricing and sufficient volume for most investors to buy and sell without moving the market significantly. The bid-ask spread on the fund is usually tight relative to the underlying municipal bonds, which themselves trade infrequently and with wider spreads. This liquidity advantage is one reason ETFs have captured market share from closed-end municipal funds. However, the underlying bonds themselves are illiquid, so during severe market stress, FMHI’s underlying holdings might become difficult to value or trade, which could widen the fund’s spread or cause its trading price to diverge from its net asset value.

Researching FMHI

The prospectus is the essential reference for understanding the fund’s objective, credit mandate, and risk controls. The fund’s monthly or quarterly fact sheet shows the current sector composition, average credit rating, duration, and yield. Holding-level detail is available through the fund’s website. Investors should compare FMHI’s recent performance against other high-income municipal ETFs and against broader muni benchmarks to assess whether the yield enhancement has been worth the additional credit risk taken. Tax considerations are paramount: investors should discuss with a tax adviser how municipal-bond income, any capital gains, and the alternative minimum tax apply to their specific circumstances.
