These are two different products. CPSN is a floor fund, which caps how far a holder can fall. DOCT 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

DOCT resets first, on Oct 16, 2026, 25 days from now; CPSN runs to Oct 30, 2026, 39 days. A fall from here reaches CPSN’s buffer after 5.7% and DOCT’s after 14.7%. 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.
