These are two different products. XDEC is a floor fund, which caps how far a holder can fall. DDEC is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.

Both are First Trust funds, so the difference between them is the terms rather than the house.

Where each one stands today

DDEC resets first, on Dec 18, 2026, 91 days from now; XDEC runs to Dec 18, 2026, 91 days. DDEC can still gain 3.0% before its cap, XDEC 1.9%. A fall from here reaches DDEC’s buffer after 12.7% and XDEC’s after 7.4%. 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.
