These are two different products. AIOO is a floor fund, which caps how far a holder can fall. DDFJ 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 DDFJ takes all of the rise up to 9.0% and nothing above it.

DDFJ 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, 83 days from now; DDFJ runs to Dec 31, 2026, 83 days. A fall from here reaches AIOO’s buffer after 0.5% and DDFJ’s after 6.9%. Both track SPY, so what separates them is where each is in its own period.

AIOO in plain words

This fund has no cap. It takes a share of any further rise in SPY. The fund's price can fall 0.5% from here before the buffer starts absorbing losses, by the issuer's figure. In index terms, SPY can fall 2.0% 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. 83 days remained on Oct 9, 2026. On Dec 31, 2026 the period ends and new terms are set.

DDFJ in plain words

SPY had already risen past this fund's cap of +9.0% for the period on Oct 9, 2026, so in index terms there is no more upside to collect. The fund's own price can still drift up to about 1.5% as the period runs out. The fund's price can fall 6.9% from here before the buffer starts absorbing losses, by the issuer's figure. In index terms, SPY can fall 12.4% 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. On Dec 31, 2026 the period ends and a new cap is set.

ETFIQ calculates every figure 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 figure is an ETFIQ calculation with distributions reinvested.
