AIOO vs XDEC: which one stands where?
As of Oct 1, 2026 XDEC can fall 7.7% before its buffer engages and AIOO 0.0%, and XDEC resets 13 days sooner. AllianzIM U.S. Equity Buffer100 ETF - Jan and FT Vest U.S. Equity Enhance & Moderate Buffer ETF - December.
AIOO: reference 0.0% since period start, fund 0.0%; buffer Floor; no cap; No cap.
XDEC: reference +12.0% since period start, fund +7.4%; buffer 0 to −15; cap +10.1%; At its cap.
These are two different products. AIOO is a floor fund, which caps how far a holder can fall. XDEC 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 XDEC takes all of the rise up to 10.1% and nothing above it.
XDEC is already at its cap, so more rise in the index adds nothing to it before the period ends.
Where each one stands today
XDEC resets first, on Dec 18, 2026, 79 days from now; AIOO runs to Dec 31, 2026, 92 days. A fall from here reaches AIOO’s buffer after 0.0% and XDEC’s after 7.7%. 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.
XDEC in plain words
SPY had already risen past this fund's cap of +10.1% 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 1.7% as the period runs out. The fund's price can fall 7.7% from here before the buffer starts absorbing losses, by the issuer's figure. In index terms, SPY can fall 10.7% from today's level to the point where the buffer begins. Protection left, in index points: 15.0% of the 15.0% buffer still sits below today's SPY level. 79 days remained on Oct 1, 2026. On Dec 18, 2026 the period ends and a new cap is set.
