These are two different products. AIOO is a floor fund, which caps how far a holder can fall. BJAN 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 BJAN takes all of the rise up to 16.5% and nothing above it.
Where each one stands today
AIOO resets first, on Dec 31, 2026, 83 days from now; BJAN runs to Dec 31, 2026, 83 days. A fall from here reaches AIOO’s buffer after 0.5% and BJAN’s after 10.9%. Both track SPY, so what separates them is where each is in its own period.
