Where each one stands today

UDEC resets first, on Nov 30, 2026, 70 days from now; DECW runs to Nov 30, 2026, 71 days. DECW can still gain 1.9% before its cap, UDEC 2.3%. A fall from here reaches DECW’s buffer after 8.5% and UDEC’s after 13.3%. 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.
