CPSUFull floor

CPSU: reference +1.5% since period start, fund +1.2%; buffer −0 to floor; cap +7.1%; Full floor.

DDTZBetween buffer and cap

DDTZ: reference +1.7% since period start, fund +2.7%; buffer 0 to −10; cap +15.4%; Between buffer and cap.

These are two different products. CPSU is a floor fund, which caps how far a holder can fall. DDTZ 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, 238 days from now; DDTZ runs to May 31, 2027, 241 days. A fall from here reaches CPSU’s buffer after 1.3% and DDTZ’s after 2.9%. 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.
