Where each one stands today
AUGM resets first, on Aug 20, 2027, 333 days from now; CPST runs to Aug 31, 2027, 344 days. A fall from here reaches AUGM’s buffer after 1.1% and CPST’s after 0.2%. 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.
