As of Nov 4, 2026. Source: ETFIQ.

They do not reset together. QBSF has 57 days of its period left and OCTU has 330, so the two are not the same bet on the same months.

Both are AllianzIM funds, so the difference between them is the terms rather than the house.

Where each one stands today

QBSF resets first, on Dec 31, 2026, 57 days from now; OCTU runs to Sep 30, 2027, 330 days. A fall from here reaches OCTU’s buffer after 1.0% and QBSF’s after 0.8%. Both track SPY, so what separates them is where each is in its own period.

How this is computed

It is a place in a set, not a rating or a recommendation.

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.
