CPSD vs DECP: which one stands where?
As of Sep 21, 2026 DECP can fall 10.2% before its buffer engages and CPSD 5.0%.
These are two different products. CPSD is a floor fund, which caps how far a holder can fall. DECP 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
CPSD resets first, on Nov 30, 2026, 70 days from now; DECP runs to Nov 30, 2026, 70 days. A fall from here reaches CPSD’s buffer after 5.0% and DECP’s after 10.2%. Both track SPY, so what separates them is where each is in its own period.
Every figure is ETFIQ’s own, from the issuer’s published outcome-period terms. A buffer ETF holds FLEX options on its reference index rather than shares, so there is no holdings overlap between two of them to report.
