As of Nov 4, 2026. Source: ETFIQ.

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

CPSD is already at its cap, so more rise in the index adds nothing to it before the period ends.

Where each one stands today

FNOV resets first, on Nov 20, 2026, 16 days from now; CPSD runs to Nov 30, 2026, 26 days. A fall from here reaches CPSD’s buffer after 5.8% and FNOV’s after 13.3%. Both track SPY, so what separates them is where each is in its own period.

How this is computed

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.
