JANP: reference +11.8% since period start, fund +9.1%; buffer 0 to −12; cap +13.9%; Between buffer and cap.

These are two different products. AIOO is a floor fund, which caps how far a holder can fall. JANP 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 JANP takes all of the rise up to 13.9% and nothing above it.

Where each one stands today

AIOO resets first, on Dec 31, 2026, 92 days from now; JANP runs to Dec 31, 2026, 92 days. A fall from here reaches AIOO’s buffer after 0.0% and JANP’s after 8.8%. 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.
