These are two different products. CPSY is a floor fund, which caps how far a holder can fall. DDTF 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. CPSY has 104 days of its period left and DDTF has 135, so the two are not the same bet on the same months.

Where each one stands today

CPSY resets first, on Jan 1, 2027, 104 days from now; DDTF runs to Jan 31, 2027, 135 days. A fall from here reaches CPSY’s buffer after 4.1% and DDTF’s after 7.5%. 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.
