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

CPSD is already at its cap, so more rise in the index adds nothing to it before the period ends.

Where each one stands today

CPSD resets first, on Nov 30, 2026, 52 days from now; DECT runs to Nov 30, 2026, 52 days. A fall from here reaches CPSD’s buffer after 5.4% and DECT’s after 11.7%. Both track SPY, so what separates them is where each is in its own period.

Every figure is an ETFIQ calculation with distributions reinvested.
