Where each one stands today

CMAY resets first, on Apr 30, 2027, 210 days from now; MAYP runs to Apr 30, 2027, 210 days. A fall from here reaches CMAY’s buffer after 6.6% and MAYP’s after 5.5%. 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.
