CJUN vs MAYM: which one stands where?
As of Sep 21, 2026 MAYM can fall 2.3% before its buffer engages and CJUN 0.4%, and MAYM resets 13 days sooner.
These are two different products. MAYM is a floor fund, which caps how far a holder can fall. CJUN 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; CJUN runs to May 31, 2027, 255 days. A fall from here reaches CJUN’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.
