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

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

Where each one stands today

BSEP resets first, on Aug 31, 2027, 344 days from now; ZSEP runs to Aug 31, 2027, 344 days. BSEP can still gain 18.6% before its cap, ZSEP 8.5%. A fall from here reaches BSEP’s buffer after 0.9% and ZSEP’s after 0.3%. 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.
