AUGU vs CPSA: which one stands where?
As of Sep 21, 2026 AUGU can fall 3.1% before its buffer engages and CPSA 0.8%, and CPSA resets 1 days sooner.
These are two different products. CPSA is a floor fund, which caps how far a holder can fall. AUGU 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
CPSA resets first, on Jul 30, 2027, 312 days from now; AUGU runs to Jul 31, 2027, 313 days. A fall from here reaches AUGU’s buffer after 3.1% and CPSA’s after 0.8%. 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.
