BJUN vs MAYM: which one stands where?
As of Sep 21, 2026 BJUN can fall 2.6% before its buffer engages and MAYM 2.3%, and MAYM resets 10 days sooner.
These are two different products. MAYM is a floor fund, which caps how far a holder can fall. BJUN 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; BJUN runs to May 31, 2027, 252 days. BJUN can still gain 15.0% before its cap, MAYM 4.7%. A fall from here reaches BJUN’s buffer after 2.6% 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.
