Where each one stands today

IDMY resets first, on Apr 30, 2027, 212 days from now; IMAY runs to Apr 30, 2027, 212 days. A fall from here reaches IDMY’s buffer after 1.8% and IMAY’s after 2.6%. Both track EFA, 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.
