GAUG vs ZSEP: which one stands where?
As of Sep 21, 2026 GAUG can fall 1.6% before its buffer engages and ZSEP 0.3%, and GAUG resets 11 days sooner.
These are two different products. ZSEP is a floor fund, which caps how far a holder can fall. GAUG 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
GAUG resets first, on Aug 20, 2027, 333 days from now; ZSEP runs to Aug 31, 2027, 344 days. GAUG can still gain 12.1% before its cap, ZSEP 8.5%. A fall from here reaches GAUG’s buffer after 1.6% 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.
