Side by side
As of Nov 4, 2026. Source: ETFIQ.
These are two different products. ZSEP is a floor fund, which caps how far a holder can fall. PSEP 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
PSEP resets first, on Aug 31, 2027, 300 days from now; ZSEP runs to Aug 31, 2027, 300 days. PSEP can still gain 14.2% before its cap, ZSEP 8.1%. A fall from here reaches PSEP’s buffer after 0.7% and ZSEP’s after 0.8%. Both track SPY, so what separates them is where each is in its own period.

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.
