They do not reset together. OCTU has 10 days of its period left and FSEP 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; FSEP runs to Sep 17, 2027, 361 days. A fall from here reaches FSEP’s buffer after 1.6% and OCTU’s after 11.2%. 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.
