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

They do not reset together. CPSD has 73 days of its period left and DDTJ has 104, so the two are not the same bet on the same months.

Where each one stands today

CPSD resets first, on Dec 1, 2026, 73 days from now; DDTJ runs to Dec 31, 2026, 104 days. A fall from here reaches CPSD’s buffer after 4.9% and DDTJ’s after 8.3%. 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.
