Where each one stands today

MAYU resets first, on Apr 30, 2027, 222 days from now; MAYC runs to Apr 30, 2027, 224 days. A fall from here reaches MAYC’s buffer after 5.7% 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.
