Where each one stands today

DDEC resets first, on Dec 18, 2026, 79 days from now; PQXX runs to Dec 31, 2026, 92 days. DDEC can still gain 2.8% before its cap, PQXX 2.4%. A fall from here reaches DDEC’s buffer after 12.9% and PQXX’s after 0.1%. 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.
