CPSP vs UAPR: which one stands where?
As of Sep 21, 2026 UAPR can fall 12.3% before its buffer engages and CPSP 3.4%.
These are two different products. CPSP is a floor fund, which caps how far a holder can fall. UAPR 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
CPSP resets first, on Mar 31, 2027, 191 days from now; UAPR runs to Mar 31, 2027, 191 days. A fall from here reaches CPSP’s buffer after 3.4% and UAPR’s after 12.3%. 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.
