CPSR vs DFEB: which one stands where?
As of Sep 21, 2026 DFEB can fall 11.7% before its buffer engages and CPSR 3.2%, and DFEB resets 7 days sooner.
These are two different products. CPSR is a floor fund, which caps how far a holder can fall. DFEB 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
DFEB resets first, on Feb 19, 2027, 151 days from now; CPSR runs to Feb 26, 2027, 158 days. A fall from here reaches CPSR’s buffer after 3.2% and DFEB’s after 11.7%. 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.
