These are two different products. CPSD is a floor fund, which caps how far a holder can fall. DDFD 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; DDFD runs to Nov 30, 2026, 70 days. A fall from here reaches CPSD’s buffer after 5.0% and DDFD’s after 7.4%. 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.
