ZALTBetween buffer and cap

ZALT: reference +1.9% since period start, fund +0.9%; buffer 0 to −10; cap +3.6%; Between buffer and cap. Figures to Oct 13, 2026.

These are two different products. AIOO is a floor fund, which caps how far a holder can fall. ZALT 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 ZALT takes all of the rise up to 3.6% and nothing above it.

Where each one stands today

AIOO resets first, on Dec 31, 2026, 79 days from now; ZALT runs to Dec 31, 2026, 79 days. A fall from here reaches AIOO’s buffer after 0.5% and ZALT’s after 0.9%. Both track SPY, so what separates them is where each is in its own period.

Every figure is an ETFIQ calculation with distributions reinvested.
