CPSY vs PBJA: which one stands where?
As of Sep 21, 2026 PBJA can fall 7.2% before its buffer engages and CPSY 4.3%.
These are two different products. CPSY is a floor fund, which caps how far a holder can fall. PBJA 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
CPSY resets first, on Dec 31, 2026, 101 days from now; PBJA runs to Dec 31, 2026, 101 days. A fall from here reaches CPSY’s buffer after 4.3% and PBJA’s after 7.2%. 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.
