Where each one stands today

GMAY resets first, on May 21, 2027, 231 days from now; CJUN runs to May 31, 2027, 241 days. A fall from here reaches CJUN’s buffer after 1.4% and GMAY’s after 4.2%. 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.
