These are two different products. AOCT is a floor fund, which caps how far a holder can fall. OCTU 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. OCTU has 363 days of its period left and AOCT has 729, so the two are not the same bet on the same months.

Where each one stands today

OCTU resets first, on Sep 30, 2027, 363 days from now; AOCT runs to Sep 30, 2028, 729 days. A fall from here reaches AOCT’s buffer after 0.5% and OCTU’s after 1.4%. Both track SPY, so what separates them is where each is in its own period.

Every figure is ETFIQ’s own, from the issuer’s published outcome-period terms. A buffer ETF holds FLEX options on its reference index rather than shares, so there is no holdings overlap between two of them to report.
