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

CPSN resets first, on Oct 29, 2027, 359 days from now; PNOV runs to Oct 31, 2027, 361 days. A fall from here reaches CPSN’s buffer after 0.3% and PNOV’s after 0.9%. 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.
