CPSR vs DDTM: which one stands where?
As of Sep 19, 2026 DDTM can fall 7.5% before its buffer engages and CPSR 3.1%, and CPSR resets 2 days sooner.
These are two different products. CPSR is a floor fund, which caps how far a holder can fall. DDTM 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
CPSR resets first, on Feb 27, 2027, 161 days from now; DDTM runs to Feb 28, 2027, 163 days. A fall from here reaches CPSR’s buffer after 3.1% and DDTM’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.
