DDTOBetween buffer and cap

DDTO: reference +2.1% since period start, fund +1.1%; buffer 0 to −10; cap +14.8%; Between buffer and cap. Figures to Oct 9, 2026.

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

They do not reset together. DDTO has 356 days of its period left and AOCT has 722, so the two are not the same bet on the same months.

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

Where each one stands today

DDTO resets first, on Sep 30, 2027, 356 days from now; AOCT runs to Sep 30, 2028, 722 days. AOCT can still gain 20.1% before its cap, DDTO 13.6%. A fall from here reaches AOCT’s buffer after 1.0% and DDTO’s after 1.1%. 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.
