AIOO vs DDFO: which one stands where?
As of Sep 19, 2026 DDFO can fall 8.3% before its buffer engages and AIOO 0.5%.
These are two different products. AIOO is a floor fund, which caps how far a holder can fall. DDFO 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 24% of whatever the index does, where DDFO takes all of the rise up to 9.0% and nothing above it.
Where each one stands today
AIOO resets first, on Sep 30, 2026, 12 days from now; DDFO runs to Sep 30, 2026, 12 days. A fall from here reaches AIOO’s buffer after 0.5% and DDFO’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.
