These are two different products. CPSP is a floor fund, which caps how far a holder can fall. UAPR is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.

Both are already at their cap, so neither gains from more rise in the index before the period ends.

Where each one stands today

CPSP resets first, on Mar 31, 2027, 173 days from now; UAPR runs to Mar 31, 2027, 173 days. A fall from here reaches CPSP’s buffer after 3.8% and UAPR’s after 12.8%. Both track SPY, so what separates them is where each is in its own period.

Every figure is an ETFIQ calculation with distributions reinvested.
