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

CPSA resets first, on Jul 30, 2027, 290 days from now; AUGW runs to Jul 31, 2027, 291 days. A fall from here reaches AUGW’s buffer after 3.1% and CPSA’s after 1.2%. Both track SPY, so what separates them is where each is in its own period.

ETFIQ calculates every figure from each issuer’s published outcome-period terms. Buffer ETFs hold options on an index, not shares, so there is no holdings overlap to report.

Every figure is an ETFIQ calculation with distributions reinvested.
