IBDT vs MYCM

IBDTAiShares iBonds Dec 2028 Term Corporate ETF

MYCMCState Street My2033 Corporate Bond ETF

In short

IBDT Acts more like a bond than a bond fund: roughly 700 investment-grade corporate bonds that all mature in 2028, wrapped in one ticker with a defined end date. Built for ladder rungs, monthly distributions and a known finish line.

MYCM Pick a year, buy a fund. MYCM holds roughly 90 US corporate bonds clustered on 2033 maturities, actively managed against an ICE benchmark and paying monthly. One rung of a bond ladder in a single ticker.

Stated mandate

IBDT The fund seeks to track an index of investment-grade corporate bonds maturing in 2028 and is designed to support income generation, bond-ladder construction, and interest-rate-risk management through a defined maturity.

MYCM The Fund seeks to maximize current income while preserving capital. It primarily invests in corporate bonds maturing in 2033 and may include bonds maturing within six months before or after that target year.

Why people hold it

• IBDT The defined 2028 maturity does the work: one ticker behaves like a ladder rung, no hunting down individual bonds or tracking each one's maturity.ishares.com
• About 700 investment-grade corporate bonds inside, so no single issuer carries the outcome the way it would in a handful of hand-picked bonds.
• Costs 0.10% a year, right at the typical fee for target-maturity bond funds, and it is one of the more actively traded names in that group.
• Launched in 2018 and now a multi-billion-dollar fund, it ranks among the strongest implementations in the target-maturity bond group.

• MYCM Defined-maturity design: corporate bonds due in 2033, give or take six months, so the portfolio has an end date instead of rolling forever like a standard bond fund.
• What's on the label is in the fund: US corporate credit on a 2033 maturity, one of the tighter mandate fits in the target-maturity group.
• Income arrives monthly, drawn from roughly 90 bonds picked by an active manager against the ICE 2033 Maturity US Corporate Index.

Worth knowing

• IBDT Vanguard's VBCB targets the same 2028 corporate maturity for 0.08%, two basis points cheaper.
• This is corporate credit, not Treasuries. The bonds are investment grade, but downgrades and defaults are still part of the picture.
• It has a finish line. When the 2028 term ends the strategy is over, so the what-next decision lands back with you.ishares.com

• MYCM At 0.15%, it runs above the 0.10% median for target-maturity bond funds, where rivals like BSCT and IBDU charge 0.10%.
• A small, thinly traded fund next to the category's entrenched ladder suites, which can mean wider bid-ask spreads on the way in and out.
• Launched in 2024, so its live record covers only a short stretch of rate and credit conditions.
