First Trust Mortgage Income Fund (FMY)
First Trust Mortgage Income Fund is a closed-end investment company that trades on the New York Stock Exchange under the ticker FMY. It exists to do one job with focus: invest primarily in mortgage-backed securities and deliver current income to shareholders, with capital preservation as a secondary objective. The fund was organized as a Massachusetts business trust in 2005 and is managed by First Trust Advisors L.P., with co-management by Brookfield Investment Management Inc.
The mechanics are straightforward on the surface. The fund holds a portfolio of mortgage-backed securities—debt instruments that represent claims against pools of residential or commercial mortgage loans. These can be pass-through certificates (the investor receives monthly principal and interest payments as homeowners pay their mortgages), collateralized mortgage obligations (CMOs, which slice cash flows into tranches with different risk profiles and maturities), or other mortgage-linked instruments issued or guaranteed by quasi-government entities like Fannie Mae and Freddie Mac.
Every mortgage payment that flows through a borrower becomes income for the fund, which distributes it to shareholders. Unlike an open-end mutual fund (where shares are issued and redeemed continuously at net asset value), FMY operates as a closed-end structure: the share count is fixed once the fund is launched, and shares trade on the stock exchange like any equity. The price floats above or below net asset value, creating a discount or premium depending on investor appetite.
This structure gives the fund a crucial advantage during interest-rate cycles. When rates fall, existing mortgage-backed securities become more valuable—borrowers with old, high-rate mortgages are less likely to refinance (slowing prepayments), and new investors will pay a premium for the higher coupons. When rates rise, the math inverts: bond prices fall, refinancing risk shrinks (borrowers stay put), and new originations offer higher yields, making the fund’s older holdings less attractive. First Trust’s managers work within these dynamics, adjusting the portfolio’s duration—the sensitivity to rate moves—to navigate the shifting environment.
The residential mortgages underlying many of the fund’s holdings are tied to the U.S. housing market. When home prices are rising and employment is steady, mortgage defaults are rare and prepayments are orderly. When home prices fall or unemployment spikes, defaults rise, prepayment speeds adjust, and the underlying mortgage pools face stress. The pandemic taught this lesson acutely: home prices surged, defaults vanished, and then as rates rose sharply in 2022–2023, prepayments slowed dramatically, extending portfolio duration in ways that depressed valuations. Commercial mortgage-backed securities face a different but related risk: the health of the office, retail, or apartment properties underlying the mortgages depends on occupancy, tenant credit quality, and property-level operating cash flow.
Interest-rate volatility has been the dominant driver of FMY’s returns in recent years. The fund’s yield and price move inversely with Treasuries. As long-term rates spike, the fund’s existing securities decline in value—the discount to NAV may widen, and shareholders who hold through the cycle absorb the loss unless yields eventually rise enough to compensate. Conversely, falling rates lift both the securities’ prices and the fund’s share price, but new shareholders buying at a premium to NAV face the risk that their premium erodes if rates rise again.
The fund uses leverage—modest borrowing—to amplify returns. A levered closed-end fund invests slightly more than the capital its shareholders have provided, boosting income in a high-yield environment but magnifying losses in a downturn. This is a conscious trade-off: shareholders accept higher volatility in net asset value in exchange for higher current yield than they would get from an unlevered fund.
Fee pressure and reinvestment risk frame the fund’s evolution. Like all closed-end fixed-income vehicles, FMY charges a management fee (currently around 0.70–1.00% annually, depending on the latest prospectus). In a low-yield world, these fees compress the effective return to shareholders. Reinvestment risk is the flip side: when mortgages pay down or securities mature, the fund must redeploy the cash into new securities at prevailing yields. If yields have fallen, the replacement securities yield less, and income per share may dwindle despite the fund’s original allocation remaining stable.
The regulatory backdrop has also shifted. Post-2008 reforms imposed stricter capital standards on banks and mortgage servicers, which affected the supply of mortgage-backed securities. The Federal Reserve’s quantitative easing programs inflated demand for these instruments and depressed yields; the subsequent tightening of the Fed balance sheet reduced demand and raised yields, rippling through funds like FMY. Renewed focus on mortgage servicing standards and borrower protections adds compliance costs to the originators and servicers that ultimately support the mortgage pools.
The fund’s appeal rests on a straightforward income proposition. For investors seeking regular distributions and exposure to the housing market without directly holding mortgages, the closed-end structure offers liquidity and professional management. But the fund’s return—total return including price appreciation or depreciation, not just yield—depends on where rates go and how far valuations are stretched. Shareholders should monitor the fund’s discount or premium to NAV, the weighted average coupon of the portfolio, and prepayment speeds in mortgage pools to sense how the fund might behave in different rate environments.
