These are two different products. QBUF is a floor fund, which caps how far a holder can fall. DQSE is a buffer fund, which absorbs the first part of a fall and leaves everything below it with the holder.

They do not reset together. QBUF has 9 days of its period left and DQSE has 361, so the two are not the same bet on the same months.

Where each one stands today

QBUF resets first, on Sep 30, 2026, 9 days from now; DQSE runs to Sep 17, 2027, 361 days. DQSE can still gain 16.2% before its cap, QBUF 4.7%. A fall from here reaches DQSE’s buffer after 2.3% and QBUF’s after 1.2%. Both track QQQ, 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.
