Where each one stands today
CPSA resets first, on Jul 30, 2027, 312 days from now; PMAU runs to Jul 31, 2027, 313 days. A fall from here reaches CPSA’s buffer after 0.8% and PMAU’s after 1.3%. 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.
