These are two different products. ZAUG is a floor fund, which caps how far a holder can fall. UAUG 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

UAUG resets first, on Jul 31, 2027, 313 days from now; ZAUG runs to Jul 31, 2027, 313 days. UAUG can still gain 11.8% before its cap, ZAUG 7.3%. A fall from here reaches UAUG’s buffer after 6.9% and ZAUG’s after 1.0%. 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.
