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

CPNQ resets first, on Dec 1, 2026, 61 days from now; QDEC runs to Dec 18, 2026, 79 days. A fall from here reaches CPNQ’s buffer after 5.6% and QDEC’s after 12.6%. Both track QQQ, so what separates them is where each is in its own period.

Every figure is ETFIQ’s own, from the issuer’s published outcome-period terms. A buffer ETF holds FLEX options on its reference index rather than shares, so there is no holdings overlap between two of them to report.
