CPSO vs DDSQ: which one stands where?
As of Sep 21, 2026 CPSO can fall 5.9% before its buffer engages and DDSQ 3.0%.
These are two different products. CPSO is a floor fund, which caps how far a holder can fall. DDSQ 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
CPSO resets first, on Sep 30, 2026, 9 days from now; DDSQ runs to Sep 30, 2026, 9 days. A fall from here reaches CPSO’s buffer after 5.9% and DDSQ’s after 3.0%. 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.
