AIOO vs OCTU: which one stands where?
As of Sep 21, 2026 OCTU can fall 11.2% before its buffer engages and AIOO 0.8%.
These are two different products. AIOO is a floor fund, which caps how far a holder can fall. OCTU is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.
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 Sep 30, 2026, 10 days from now; OCTU runs to Sep 30, 2026, 10 days. A fall from here reaches AIOO’s buffer after 0.8% and OCTU’s after 11.2%. 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.
