CPSM vs DDTY: which one stands where?
As of Sep 21, 2026 DDTY can fall 5.7% before its buffer engages and CPSM 2.0%.
These are two different products. CPSM is a floor fund, which caps how far a holder can fall. DDTY 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
CPSM resets first, on Apr 30, 2027, 221 days from now; DDTY runs to Apr 30, 2027, 221 days. A fall from here reaches CPSM’s buffer after 2.0% and DDTY’s after 5.7%. 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.
