Where each one stands today
PBOC resets first, on Sep 30, 2026, 9 days from now; QBSF runs to Sep 30, 2026, 10 days. PBOC can still gain 0.1% before its cap, QBSF 0.4%. A fall from here reaches PBOC’s buffer after 9.3% and QBSF’s after 2.5%. 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.
