State Street My2035 Corporate Bond ETF (MYCO)

State Street Global Advisors launched the My2035 Corporate Bond ETF (MYCO) as part of a family of maturity-targeted funds designed to simplify fixed-income investing for retail and institutional investors who want to own corporate credit exposure with a specific time horizon in mind. The fund tracks investment-grade corporate bonds expected to mature in or near 2035, offering a straightforward alternative to building that maturity ladder yourself.

The idea behind maturity-targeted funds

The My2035 fund reflects a broader trend in fixed-income investing: the shift away from buying individual bonds toward using funds that handle rebalancing automatically. In the traditional approach, an investor buys a ladder of bonds with staggered maturity dates, collecting principal and coupons at planned intervals. That strategy works well for large institutional investors and wealthy individuals, but retail investors face practical limits — buying enough individual corporates to be meaningfully diversified is expensive, and monitoring dozens of holdings is cumbersome.

State Street’s My-series funds automate that process. Rather than holding bonds indefinitely, the fund continuously replaces maturing bonds with new ones, maintaining the target maturity around 2035. This means that as calendar years pass and 2035 approaches, the fund’s portfolio automatically shifts toward shorter maturities, naturally de-risking without requiring the investor to trade anything themselves.

How MYCO’s holdings evolve

On the day the fund launches or is observed, bonds in the portfolio are selected to mature around 2035, creating a roughly ten-year duration profile. As years tick forward, the fund’s rebalancing routine refreshes the maturity targets. If it is now 2026, a fund targeting 2035 is holding nine-year bonds; in 2027 it will hold eight-year bonds. The effect is that the fund’s interest-rate sensitivity gradually declines, approaching a much shorter duration as the target maturity date approaches. By 2034, just a year before the target, MYCO would hold almost all one-year bonds or shorter.

This automatic duration shortening is a feature for investors with a specific time horizon. Someone buying MYCO in 2024 expecting to hold it until they need the money in 2035 benefits from the fund’s design: the interest-rate risk naturally falls as their investment horizon shrinks.

Investment-grade corporate credit

All bonds in MYCO carry investment-grade ratings from major rating agencies. That means they are bonds issued by established, creditworthy corporations — industrial manufacturers, financial firms, utilities, consumer-goods companies, and other sectors with stable cash flows. Investment-grade corporates offer higher yields than government bonds because corporate issuers carry default risk, even if small. In exchange for that slightly higher risk, investors earn more income.

The fund diversifies across issuers and industries to spread credit risk. No single company or sector dominates the portfolio, so the failure of any one firm affects the fund marginally. Still, corporates as a category are sensitive to economic conditions: in a severe recession, even investment-grade companies can encounter stress and default.

Cost, income, and liquidity

MYCO, as a passively managed ETF, carries a modest expense ratio that covers State Street’s costs for fund administration and index tracking. The fund distributes income (coupon payments from the bonds) to shareholders, typically monthly. As an exchange-traded product, MYCO trades on NASDAQ during standard market hours, and investors can buy or sell shares like any stock. The bid-ask spread and trading volume depend on how much volume the fund commands; more liquid funds usually offer tighter spreads than lightly traded ones.

Risks and considerations

Interest-rate risk is the dominant concern: when rates rise, bond prices fall, including bonds held in MYCO, and vice versa. The roughly nine-year duration of the fund makes it moderately sensitive to rate moves. Credit risk is secondary but real: if the investment-grade corporate sector weakens, MYCO’s bonds could decline in value or face missed payments, though such a severe outcome is uncommon. Inflation risk also applies — if inflation accelerates, the real value of the fixed coupons shrinks.

Research pathways

Investors exploring MYCO should begin with State Street Global Advisors’ official fund factsheet and prospectus, which detail the exact index methodology, current holdings, and expense ratio. The fund’s performance history is available through most major brokerage platforms and fund-tracking websites. A key metric is how closely MYCO tracks its underlying index (tracking error), which indicates the fund’s operational efficiency. Understanding the broader corporate-bond market — particularly the yield curve and credit spreads — helps frame MYCO’s expected return and risk within the broader fixed-income landscape.
