Where each one stands today
DECU resets first, on Nov 30, 2026, 71 days from now; SIXD runs to Nov 30, 2026, 71 days. A fall from here reaches DECU’s buffer after 9.2% and SIXD’s after 2.8%. 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.
