BMAYBetween buffer and cap

BMAY: reference +8.3% since period start, fund +6.6%; buffer 0 to −9; cap +16.9%; Between buffer and cap. Figures to Oct 9, 2026.

DDTYBetween buffer and cap

DDTY: reference +8.3% since period start, fund +6.3%; buffer 0 to −10; cap +14.6%; Between buffer and cap. Figures to Oct 9, 2026.

These are two different products. DDTY is a floor fund, which caps how far a holder can fall. BMAY is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.

Both are Innovator funds, so the difference between them is the terms rather than the house.

Where each one stands today

BMAY resets first, on Apr 30, 2027, 203 days from now; DDTY runs to Apr 30, 2027, 203 days. BMAY can still gain 9.4% before its cap, DDTY 7.4%. A fall from here reaches BMAY’s buffer after 6.5% and DDTY’s after 6.3%. Both track SPY, so what separates them is where each is in its own period.

ETFIQ calculates every figure from each issuer’s published outcome-period terms. Buffer ETFs hold options on an index, not shares, so there is no holdings overlap to report.

Every figure is an ETFIQ calculation with distributions reinvested.
