APXM vs CPSM: which one stands where?
As of Sep 21, 2026 APXM can fall 3.2% before its buffer engages and CPSM 2.0%, and APXM resets 14 days sooner.
These are two different products. CPSM is a floor fund, which caps how far a holder can fall. APXM 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
APXM resets first, on Apr 16, 2027, 207 days from now; CPSM runs to Apr 30, 2027, 221 days. A fall from here reaches APXM’s buffer after 3.2% and CPSM’s after 2.0%. 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.
