Side by side
As of Nov 4, 2026. Source: ETFIQ.
These are two different products. ZJUN is a floor fund, which caps how far a holder can fall. JUNP 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
JUNP resets first, on May 31, 2027, 208 days from now; ZJUN runs to May 31, 2027, 208 days. JUNP can still gain 13.0% before its cap, ZJUN 6.0%. A fall from here reaches JUNP’s buffer after 2.5% and ZJUN’s after 1.9%. Both track SPY, so what separates them is where each is in its own period.
