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

XJAN resets first, on Jan 15, 2027, 119 days from now; CPSF runs to Jan 30, 2027, 133 days. A fall from here reaches CPSF’s buffer after 3.4% and XJAN’s after 6.7%. Both track SPY, 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.
