QBSV vs XSEP: which one stands where?
As of Sep 21, 2026 QBSV can fall 3.5% before its buffer engages and XSEP 1.2%, and QBSV resets 351 days sooner.
These are two different products. XSEP is a floor fund, which caps how far a holder can fall. QBSV 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. QBSV has 10 days of its period left and XSEP has 361, so the two are not the same bet on the same months.
Where each one stands today
QBSV resets first, on Sep 30, 2026, 10 days from now; XSEP runs to Sep 17, 2027, 361 days. QBSV can still gain 1.7% before its cap, XSEP 9.9%. A fall from here reaches QBSV’s buffer after 3.5% and XSEP’s after 1.2%. 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.
