CPSJ vs FJUN: which one stands where?
As of Sep 21, 2026 FJUN can fall 3.6% before its buffer engages and CPSJ 1.2%, and FJUN resets 13 days sooner.
These are two different products. CPSJ is a floor fund, which caps how far a holder can fall. FJUN 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
FJUN resets first, on Jun 17, 2027, 269 days from now; CPSJ runs to Jun 30, 2027, 282 days. A fall from here reaches CPSJ’s buffer after 1.2% and FJUN’s after 3.6%. 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.
