These are two different products. AIOO is a floor fund, which caps how far a holder can fall. PQX is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.

AIOO has no cap. It takes 30% of whatever the index does, where PQX takes all of the rise up to 3.5% and nothing above it.

Where each one stands today

AIOO resets first, on Dec 31, 2026, 79 days from now; PQX runs to Dec 31, 2026, 79 days. A fall from here reaches AIOO’s buffer after 0.5% and PQX’s after 0.9%. Both track SPY, so what separates them is where each is in its own period.

ETFIQ calculates every figure from each issuer’s published outcome-period terms. Buffer ETFs hold options on an index, not shares, so there is no holdings overlap to report.

Every figure is an ETFIQ calculation with distributions reinvested.
