IBMQ vs MYMK

IBMQAiShares iBonds Dec 2028 Term Muni Bond ETF

MYMKDState Street My2031 Municipal Bond ETF

In short

IBMQ A muni ladder rung in ETF form: thousands of investment-grade bonds that mature or get called by late 2028, then the fund winds up and pays out. AMT-free index, income paid monthly.

MYMK A single rung of a muni ladder: MYMK holds tax-exempt bonds maturing in 2031, then returns remaining principal and closes on or about December 15, 2031. Unlike the big index ladders, a State Street team picks the bonds.

Stated mandate

IBMQ The fund seeks to track an index of investment-grade U.S. municipal bonds that are expected to mature or be redeemed before December 2, 2028.

MYMK The fund is an actively managed target-maturity municipal bond strategy focused primarily on bonds maturing in 2031. It seeks current federal-tax-exempt income while also seeking capital preservation.

Why people hold it

• IBMQ Acts like a single bond with a known end date: it holds munis maturing or redeemed before December 2, 2028, then terminates and distributes net assets.ishares.com
• Spreads one ladder rung across thousands of investment-grade municipal bonds, far more than a retail buyer could assemble directly, and pays monthly.
• The tracked index is AMT-free, screening out bonds whose interest counts toward the alternative minimum tax.
• Costs 0.10% a year, in line with the typical target-maturity bond fund, and this 2028 rung has been running since 2019.

• MYMK Actively managed rather than index-tracked: the team works top-down across sectors and issuers, with the ICE 2031 Maturity US Broad Municipal Index as the yardstick.businesswire.comssga.com
• The defined end date does the work of a maturity: the fund distributes any remaining principal and liquidates on or about December 15, 2031.ssga.com
• Income is exempt from regular federal income tax and paid monthly, with preservation of capital named as the second goal.
• Roughly 80 bonds spread issuer risk that you would carry concentrated if you bought a couple of individual munis yourself.

Worth knowing

• IBMQ Callable-adjusted by design: munis can be redeemed early, so cash can come back ahead of schedule and the final wind-up payout is not a fixed number.
• Until it terminates it trades like any bond fund, with prices moving on rates, and volume is moderate rather than heavy.
• Same 0.10% as corporate rungs like IBDU and BSCT, while Treasury rungs such as IBTJ run cheaper at 0.07%; the muni tax treatment is the reason to pay it.

• MYMK The 0.20% fee sits above index-run ladder rungs like iShares iBonds (IBTJ) and Invesco BulletShares (BSCT). That is the price of a manager picking bonds.
• Small and thinly traded next to the established ladder families, so the bid-ask spread is a real part of your cost.
• In the target year, proceeds from bonds maturing before the liquidation date may sit in cash and cash equivalents, which can trim income in the final stretch.ssga.com
