AIOONo cap

AIOO: reference 0.0% since period start, fund 0.0%; buffer Floor; no cap; No cap.

JANUNo cap

JANU: reference +11.8% since period start, fund +8.2%; buffer 0 to −15; no cap; No cap.

These are two different products. AIOO is a floor fund, which caps how far a holder can fall. JANU 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 Dec 31, 2026, 92 days from now; JANU runs to Dec 31, 2026, 92 days. A fall from here reaches AIOO’s buffer after 0.0% and JANU’s after 8.3%. 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.
