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

CPRO resets first, on Sep 30, 2027, 356 days from now; KOCT runs to Sep 30, 2027, 356 days. A fall from here reaches CPRO’s buffer after 0.4% and KOCT’s after 0.5%. Both track IWM, so what separates them is where each is in its own period.

How this is computed

ETFIQ calculates every figure 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 figure is an ETFIQ calculation with distributions reinvested.
