As of Nov 4, 2026. Source: ETFIQ.

These are two different products. XBOC 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 XBOC has 330, 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; XBOC runs to Sep 30, 2027, 330 days. QBSF can still gain 2.1% before its cap, XBOC 12.7%. A fall from here reaches QBSF’s buffer after 0.8% and XBOC’s after 0.9%. Both track SPY, so what separates them is where each is in its own period.

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.
