These are two different products. CPSN is a floor fund, which caps how far a holder can fall. PBNV is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.
Both are already at their cap, so neither gains from more rise in the index before the period ends.
Where each one stands today
CPSN resets first, on Oct 30, 2026, 21 days from now; PBNV runs to Oct 31, 2026, 22 days. A fall from here reaches CPSN’s buffer after 6.1% and PBNV’s after 9.8%. Both track SPY, so what separates them is where each is in its own period.
