As of Nov 4, 2026. Source: ETFIQ.

These are two different products. AOCT is a floor fund, which caps how far a holder can fall. OCTT 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. OCTT has 330 days of its period left and AOCT has 696, so the two are not the same bet on the same months.

Where each one stands today

OCTT resets first, on Sep 30, 2027, 330 days from now; AOCT runs to Sep 30, 2028, 696 days. AOCT can still gain 20.0% before its cap, OCTT 16.5%. A fall from here reaches AOCT’s buffer after 1.1% and OCTT’s after 1.4%. Both track SPY, so what separates them is where each is in its own period.

How this is computed

ETFIQ calculates every number 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 number is an ETFIQ calculation with distributions reinvested.
