These are two different products. SEPM 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 10 days of its period left and SEPM has 361, so the two are not the same bet on the same months.

Where each one stands today

OCTU resets first, on Sep 30, 2026, 10 days from now; SEPM runs to Sep 17, 2027, 361 days. A fall from here reaches OCTU’s buffer after 11.2% and SEPM’s after 1.1%. 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.
