As of Nov 4, 2026. Source: ETFIQ.

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

Both are already at their cap, so neither gains from more rise in the index before the period ends.

Where each one stands today

GNOV resets first, on Nov 20, 2026, 16 days from now; ZDEK runs to Nov 30, 2026, 26 days. GNOV can still gain 0.5% before its cap, ZDEK 0.5%. A fall from here reaches GNOV’s buffer after 11.3% and ZDEK’s after 6.0%. 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.
