These are two different products. CPSP is a floor fund, which caps how far a holder can fall. DMAR 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
DMAR resets first, on Mar 19, 2027, 157 days from now; CPSP runs to Mar 31, 2027, 169 days. A fall from here reaches CPSP’s buffer after 3.8% and DMAR’s after 13.4%. Both track SPY, so what separates them is where each is in its own period.
