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

GFEB resets first, on Feb 19, 2027, 151 days from now; CPSR runs to Feb 26, 2027, 158 days. A fall from here reaches CPSR’s buffer after 3.2% and GFEB’s after 7.2%. 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.
