AIOO vs DSEP: which one stands where?
As of Sep 21, 2026 DSEP can fall 6.6% before its buffer engages and AIOO 0.8%, and AIOO resets 351 days sooner.
These are two different products. AIOO is a floor fund, which caps how far a holder can fall. DSEP 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 DSEP takes all of the rise up to 14.6% and nothing above it.
They do not reset together. AIOO has 10 days of its period left and DSEP has 361, so the two are not the same bet on the same months.
Where each one stands today
AIOO resets first, on Sep 30, 2026, 10 days from now; DSEP runs to Sep 17, 2027, 361 days. A fall from here reaches AIOO’s buffer after 0.8% and DSEP’s after 6.6%. 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.
