AIOO vs UJAN: which one stands where?
As of Oct 1, 2026 UJAN can fall 12.1% before its buffer engages and AIOO 0.0%. AllianzIM U.S. Equity Buffer100 ETF - Jan and Innovator U.S. Equity Ultra Buffer ETF - Jan.
AIOO: reference 0.0% since period start, fund 0.0%; buffer Floor; no cap; No cap.
UJAN: reference +11.8% since period start, fund +7.3%; buffer −5 to −35; cap +11.4%; At its cap.
These are two different products. AIOO is a floor fund, which caps how far a holder can fall. UJAN 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 UJAN takes all of the rise up to 11.4% and nothing above it.
UJAN is already at its cap, so more rise in the index adds nothing to it before the period ends.
Where each one stands today
AIOO resets first, on Dec 31, 2026, 92 days from now; UJAN runs to Dec 31, 2026, 92 days. A fall from here reaches AIOO’s buffer after 0.0% and UJAN’s after 12.1%. 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.

AIOO in plain words
This fund has no cap. It takes a share of any further rise in SPY. Protection left, in index points: 100.0% of the 100.0% buffer still sits below today's SPY level. 92 days remained on Oct 1, 2026. On Dec 31, 2026 the period ends and a new cap is set.
UJAN in plain words
SPY had already risen past this fund's cap of +11.4% for the period on Oct 1, 2026, so in index terms there is no more upside to collect. The fund's own price can still drift up to about 3.2% as the period runs out. The fund's price can fall 12.1% from here before the buffer starts absorbing losses, by the issuer's figure. In index terms, SPY can fall 15.1% from today's level to the point where the buffer begins. Protection left, in index points: 30.0% of the 30.0% buffer still sits below today's SPY level.
