CPSP vs DMAR: which one stands where?
As of Sep 21, 2026 DMAR can fall 12.9% before its buffer engages and CPSP 3.4%, and DMAR resets 12 days sooner.
These are two different products. CPSP is a floor fund, which caps how far a holder can fall. DMAR 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
DMAR resets first, on Mar 19, 2027, 179 days from now; CPSP runs to Mar 31, 2027, 191 days. A fall from here reaches CPSP’s buffer after 3.4% and DMAR’s after 12.9%. 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.
