Where each one stands today
FEBU resets first, on Jan 31, 2027, 131 days from now; SIXF runs to Jan 31, 2027, 131 days. A fall from here reaches FEBU’s buffer after 8.5% and SIXF’s after 2.6%. 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.
