Side by side
As of Nov 4, 2026. Source: ETFIQ.
These are two different products. AIOO is a floor fund, which caps how far a holder can fall. DDTO 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 DDTO takes all of the rise up to 14.8% and nothing above it.
They do not reset together. AIOO has 57 days of its period left and DDTO has 330, so the two are not the same bet on the same months.
Where each one stands today
AIOO resets first, on Dec 31, 2026, 57 days from now; DDTO runs to Sep 30, 2027, 330 days. A fall from here reaches AIOO’s buffer after 0.3% and DDTO’s after 0.7%. Both track SPY, so what separates them is where each is in its own period.

AIOO
This fund has no cap. It takes a share of any further rise in SPY. The fund's price can fall 0.3% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 0.5% from today's level to the point where the buffer begins. Protection left, in index points: 100.0% of the 100.0% buffer still sits below today's SPY level. 57 days remained on Nov 4, 2026. On Dec 31, 2026 the period ends and new terms are set.
DDTO
From its price on Nov 4, 2026, the fund can gain about 14.1% more before it reaches its cap. The fund's price can fall 0.7% from here before the buffer starts absorbing losses, by the issuer's number. Protection left, in index points: 10.0% of the 10.0% buffer still sits below today's SPY level. 330 days remained on Nov 4, 2026. On Sep 30, 2027 the period ends and a new cap is set.

How this is computed
ETFIQ calculates every number from each issuer’s published outcome-period terms. Buffer ETFs hold options on an index, not shares, so there is no holdings overlap to report.
Every number is an ETFIQ calculation with distributions reinvested.
