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

CPSN resets first, on Oct 30, 2026, 39 days from now; BNOV runs to Oct 31, 2026, 40 days. A fall from here reaches BNOV’s buffer after 11.6% and CPSN’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.
