Figures to Oct 9, 2026.
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.
CPSN is already at its cap, so more rise in the index adds nothing to it before the period ends.
Where each one stands today
CPSN resets first, on Oct 30, 2026, 21 days from now; BNOV runs to Oct 31, 2026, 22 days. A fall from here reaches BNOV’s buffer after 12.5% and CPSN’s after 6.1%. Both track SPY, so what separates them is where each is in its own period.
