Where each one stands today

CPSR resets first, on Feb 26, 2027, 158 days from now; PMMR runs to Feb 28, 2027, 160 days. A fall from here reaches CPSR’s buffer after 3.2% and PMMR’s after 3.4%. 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.
