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

CPRJ has fallen through its protection. The index is 0.1% below where the buffer stops, and that part of the loss is the holder’s.

They do not reset together. CPRJ has 273 days of its period left and SCAU has 304, so the two are not the same bet on the same months.

Where each one stands today

CPRJ resets first, on Jul 1, 2027, 273 days from now; SCAU runs to Jul 31, 2027, 304 days. A fall from here reaches CPRJ’s buffer after 0.0% and SCAU’s after 0.0%. Both track IWM, 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.
