CPSF vs UFEB: which one stands where?
As of Sep 21, 2026 UFEB can fall 11.4% before its buffer engages and CPSF 3.7%, and CPSF resets 2 days sooner.
These are two different products. CPSF is a floor fund, which caps how far a holder can fall. UFEB 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
CPSF resets first, on Jan 29, 2027, 130 days from now; UFEB runs to Jan 31, 2027, 132 days. A fall from here reaches CPSF’s buffer after 3.7% and UFEB’s after 11.4%. 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.
