Where each one stands today
FDEC resets first, on Dec 18, 2026, 88 days from now; SIXJ runs to Dec 31, 2026, 102 days. FDEC can still gain 3.4% before its cap, SIXJ 4.9%. A fall from here reaches FDEC’s buffer after 10.0% and SIXJ’s after 3.1%. 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.
