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

MAYM resets first, on May 21, 2027, 242 days from now; JUNC runs to May 31, 2027, 255 days. A fall from here reaches JUNC’s buffer after 0.4% and MAYM’s after 2.3%. 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.
