DDFN vs SIXZ: which one stands where?
As of Sep 21, 2026 DDFN can fall 8.3% before its buffer engages and SIXZ 5.6%.
These are two different products. SIXZ is a floor fund, which caps how far a holder can fall. DDFN is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.
Where each one stands today
DDFN resets first, on Oct 31, 2026, 40 days from now; SIXZ runs to Oct 31, 2026, 40 days. DDFN can still gain 0.9% before its cap, SIXZ 1.8%. A fall from here reaches DDFN’s buffer after 8.3% and SIXZ’s after 5.6%. 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.
