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

Where each one stands today

PBSE resets first, on Aug 31, 2027, 344 days from now; ZSEP runs to Aug 31, 2027, 344 days. PBSE can still gain 11.3% before its cap, ZSEP 8.5%. A fall from here reaches PBSE’s buffer after 1.0% 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.
