Where each one stands today

GDEC resets first, on Dec 18, 2026, 79 days from now; QBSF runs to Dec 31, 2026, 92 days. GDEC can still gain 2.8% before its cap, QBSF 2.7%. A fall from here reaches GDEC’s buffer after 8.4% and QBSF’s after 0.2%. 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.
