These are two different products. CPSU is a floor fund, which caps how far a holder can fall. DDFZ 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

CPSU resets first, on May 28, 2027, 249 days from now; DDFZ runs to May 31, 2027, 252 days. A fall from here reaches CPSU’s buffer after 1.1% and DDFZ’s after 2.5%. 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.
