IBDT vs MYCO

IBDTAiShares iBonds Dec 2028 Term Corporate ETF

MYCODState Street My2035 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.

MYCO Most 2035 bond rungs are index ladders. MYCO is the hand-built one: an actively managed basket of corporate bonds all maturing in 2035, chosen sector by sector and issuer by issuer.

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.

MYCO The fund actively manages a portfolio primarily of corporate bonds maturing in 2035. It seeks current income and capital preservation through top-down sector allocation and bottom-up issuer and security research.

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.

• MYCO Active in an aisle built mostly from index trackers: top-down sector allocation, bottom-up issuer and security research, measured against the ICE 2035 Maturity US Corporate Index.ssga.com
• The holdings share a maturity year, so the portfolio winds down on a known calendar rather than rolling forever like a standard corporate bond fund.ssga.com
• Stated goals are current income and capital preservation, with a monthly income policy and roughly 100 corporate bonds spreading the issuer risk.

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

• MYCO 0.15% a year sits above the target-maturity median. The big index rungs charge less (IBDU and BSCT at 0.10%, VBCB at 0.08%). That gap is the price of the active seat.
• A 2025 launch, small and thinly traded: spreads can run wider than the category's giants, and there is little live history to judge the managers on.
• This is corporate credit with a long runway. Values move with interest rates and credit spreads for years before those 2035 bonds come due.
