Where each one stands today
CPSU resets first, on May 28, 2027, 249 days from now; PMJN runs to May 31, 2027, 252 days. A fall from here reaches CPSU’s buffer after 1.1% and PMJN’s after 1.6%. 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.
