CPNJBuffer working

CPNJ: reference −0.4% since period start, fund +0.7%; buffer −0 to floor; cap +7.8%; Buffer working.

QJNBuffer working

QJN: reference −0.4% since period start, fund +1.6%; buffer 0 to −10; cap +21.9%; Buffer working.

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

CPNJ has fallen through its protection. The index is 0.2% below where the buffer stops, and that part of the loss is the holder’s.

Where each one stands today

CPNJ resets first, on May 29, 2027, 240 days from now; QJN runs to May 31, 2027, 243 days. A fall from here reaches CPNJ’s buffer after 0.8% and QJN’s after 0.0%. 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.
