As of Nov 4, 2026. Source: ETFIQ.

These are two different products. HMAY is a floor fund, which caps how far a holder can fall. MAYW 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

MAYW resets first, on Apr 30, 2027, 177 days from now; HMAY runs to Apr 30, 2027, 178 days. A fall from here reaches HMAY’s buffer after 4.1% and MAYW’s after 5.0%. Both track SPY, so what separates them is where each is in its own period.

How this is computed

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