These are two different products. CPSO is a floor fund, which caps how far a holder can fall. EALT 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

CPSO resets first, on Sep 30, 2026, 9 days from now; EALT runs to Sep 30, 2026, 9 days. A fall from here reaches CPSO’s buffer after 5.9% and EALT’s after 8.3%. 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.
