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

CPNJ resets first, on May 28, 2027, 227 days from now; QQJN runs to May 31, 2027, 230 days. A fall from here reaches CPNJ’s buffer after 1.1% and QQJN’s after 0.1%. Both track QQQ, 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.
