Where each one stands today
NVBU resets first, on Oct 31, 2026, 40 days from now; SIXZ runs to Oct 31, 2026, 40 days. A fall from here reaches NVBU’s buffer after 9.1% 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.
