UMAY vs ZMAY: which one stands where?
As of Sep 21, 2026 UMAY can fall 9.2% before its buffer engages and ZMAY 2.5%.
These are two different products. ZMAY is a floor fund, which caps how far a holder can fall. UMAY is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.
Both are Innovator funds, so the difference between them is the terms rather than the house.
Where each one stands today
UMAY resets first, on Apr 30, 2027, 221 days from now; ZMAY runs to Apr 30, 2027, 221 days. UMAY can still gain 7.6% before its cap, ZMAY 4.6%. A fall from here reaches UMAY’s buffer after 9.2% and ZMAY’s after 2.5%. 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.
