As of Nov 4, 2026. Source: ETFIQ.

These are two different products. AIOO is a floor fund, which caps how far a holder can fall. BOCT 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 BOCT takes all of the rise up to 20.2% and nothing above it.

They do not reset together. AIOO has 57 days of its period left and BOCT has 330, so the two are not the same bet on the same months.

Where each one stands today

AIOO resets first, on Dec 31, 2026, 57 days from now; BOCT runs to Sep 30, 2027, 330 days. A fall from here reaches AIOO’s buffer after 0.3% and BOCT’s after 0.7%. Both track SPY, so what separates them is where each is in its own period.

ETFIQ calculates every number 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 number is an ETFIQ calculation with distributions reinvested.
