These are two different products. HMAY is a floor fund, which caps how far a holder can fall. MAYU is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.

Where each one stands today

MAYU resets first, on Apr 30, 2027, 222 days from now; HMAY runs to Apr 30, 2027, 224 days. A fall from here reaches HMAY’s buffer after 5.0% and MAYU’s after 6.0%. 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.
