These are two different products. CPSA is a floor fund, which caps how far a holder can fall. CAUG 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; CAUG runs to Jul 31, 2027, 291 days. A fall from here reaches CAUG’s buffer after 2.6% and CPSA’s after 1.2%. Both track SPY, so what separates them is where each is in its own period.
