AIOONo cap

AIOO: reference 0.0% since period start, fund 0.0%; buffer Floor; no cap; No cap.

TJANAt its cap

TJAN: reference +30.1% since period start, fund +12.8%; buffer Floor; cap +15.9%; At its cap.

AIOO has no cap. It takes 30% of whatever the index does, where TJAN takes all of the rise up to 15.9% and nothing above it.

TJAN 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, 92 days from now; TJAN runs to Dec 31, 2026, 92 days. A fall from here reaches AIOO’s buffer after 0.0% and TJAN’s after 12.8%. 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.

TJAN in plain words

SPY had already risen past this fund's cap of +15.9% 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 1.4% as the period runs out. The fund's price can fall 12.8% from here before the buffer starts absorbing losses, by the issuer's figure. In index terms, SPY can fall 23.1% from today's level to the point where the buffer begins.
