Where each one stands today

BSEP resets first, on Aug 31, 2027, 333 days from now; SEPW runs to Aug 31, 2027, 333 days. BSEP can still gain 19.1% before its cap, SEPW 11.1%. A fall from here reaches BSEP’s buffer after 0.6% and SEPW’s after 1.2%. 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.
