In short

IBMO —No data

Stated mandate

IBMO —No data

MYMI The fund is actively managed and seeks current income exempt from regular federal income taxes while pursuing capital preservation. It invests primarily in municipal bonds maturing in 2029 and is intended to distribute remaining principal and liquidate around December 15, 2029.

Why people hold it

IBMO —No data

• MYMI Built to end: it holds munis maturing in 2029, then distributes any remaining principal and liquidates on or about December 15, 2029. A bond-like maturity date in an ETF wrapper.ssga.com
• Actively managed, not rules-based: State Street runs top-down risk work plus bottom-up research to overweight sectors and issuers it finds attractive. Rare in a ladder aisle built on indexes.ssga.com
• Income targets an exemption from regular federal income taxes, and it pays monthly, which lines up with how ladder investors actually spend cash.
• One rung in the MyIncome suite, so maturity years can be stacked into a custom ladder instead of bought one-off.ssga.com

Worth knowing

IBMO —No data

• MYMI The 0.20% fee runs about double the target-maturity median. Index rungs like IBTJ, IBDU and BSCT sit at 0.07% to 0.10%, so active muni selection is the thing you are paying for.
• Launched in 2024 and still small and thinly traded next to the entrenched iBonds and BulletShares rungs, so spreads can be wide. Limit orders matter.
• Active means the roughly 100 bonds reflect the team's calls, not a fixed rulebook, and results can drift from the ICE 2029 Maturity US Broad Municipal Index it is measured against.
