SEPU vs XAUG: which one stands where?
As of Sep 21, 2026 XAUG can fall 1.6% before its buffer engages and SEPU 1.4%, and XAUG resets 12 days sooner.
These are two different products. XAUG is a floor fund, which caps how far a holder can fall. SEPU 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
XAUG resets first, on Aug 20, 2027, 333 days from now; SEPU runs to Aug 31, 2027, 345 days. A fall from here reaches SEPU’s buffer after 1.4% and XAUG’s after 1.6%. 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.
