These are two different products. AIOO is a floor fund, which caps how far a holder can fall. QBSF 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 QBSF takes all of the rise up to 2.9% and nothing above it.
Both are AllianzIM funds, so the difference between them is the terms rather than the house.
Where each one stands today
AIOO resets first, on Dec 31, 2026, 79 days from now; QBSF runs to Dec 31, 2026, 79 days. A fall from here reaches AIOO’s buffer after 0.5% and QBSF’s after 0.8%. Both track SPY, so what separates them is where each is in its own period.
