Side by side
As of Nov 4, 2026. Source: ETFIQ.
These are two different products. XSEP is a floor fund, which caps how far a holder can fall. QBSF 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. QBSF has 57 days of its period left and XSEP has 317, so the two are not the same bet on the same months.
Where each one stands today
QBSF resets first, on Dec 31, 2026, 57 days from now; XSEP runs to Sep 17, 2027, 317 days. QBSF can still gain 2.1% before its cap, XSEP 9.4%. A fall from here reaches QBSF’s buffer after 0.8% and XSEP’s after 1.7%. Both track SPY, so what separates them is where each is in its own period.
QBSF
From its price on Nov 4, 2026, the fund can gain about 2.1% more before it reaches its cap. The fund's price can fall 0.8% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 0.5% from today's level to the point where the buffer begins. Protection left, in index points: 15.0% of the 15.0% buffer still sits below today's SPY level. 57 days remained on Nov 4, 2026. On Dec 31, 2026 the period ends and a new cap is set.
XSEP
From its price on Nov 4, 2026, the fund can gain about 9.4% more before it reaches its cap. The fund's price can fall 1.7% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 0.6% from today's level to the point where the buffer begins. 317 days remained on Nov 4, 2026. On Sep 17, 2027 the period ends and a new cap is set.

How this is computed
ETFIQ calculates every number from each issuer’s published outcome-period terms. Buffer ETFs hold options on an index, not shares, so there is no holdings overlap to report.
Every number is an ETFIQ calculation with distributions reinvested.
