Our read on each fund

ETF.net Research

IBDTAiShares iBonds Dec 2028 Term Corporate ETF

MYCKCState Street My2031 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.

MYCK Most 2031 ladder rungs just clone an index. MYCK is State Street's actively managed version: people pick the corporate bonds, and the fund is built to hand back remaining principal and wind up on or about December 15, 2031.

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.

MYCK The fund seeks current income and capital preservation through an actively managed portfolio focused primarily on corporate bonds maturing in 2031.

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.

MYCK Active where the category is mostly passive: sector and issuer tilts come from State Street's own research rather than index replication.ssga.com
Behaves like a bond you hold to the end: designed to distribute any remaining principal and liquidate on or about December 15, 2031.ssga.com
Pays monthly, and it is one rung in State Street's MyIncome suite, so ladders can be built year by year with matching plumbing.ssga.com
The label matches the contents: roughly 150 corporate bonds, all pointed at 2031, seeking income with capital preservation.

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

MYCK Active costs more: 0.15% a year against a 0.10% cohort median and the 0.10% charged by index rungs like IBDU and BSCU.
A small, lightly traded fund next to the giant iBonds and BulletShares rungs, so bid-ask spreads can be wider than the headline fee suggests.
Active also means results can diverge from the ICE 2031 Maturity US Corporate Index it is measured against, either direction, and it only launched in 2024.ssga.com
