If the market falls into a bear market from here, how much does the buffer absorb?
A percentile among the 293 buffer ETFs with a live outcome period. It is a position in a set, not a rating, and neither end of it is a recommendation. All buffer ETFs ranked by it · How it is computed
Both are AllianzIM funds, so the difference between them is the terms rather than the house.
Where each one stands today
OCTU resets first, on Sep 30, 2026, 10 days from now; SIXO runs to Sep 30, 2026, 10 days. A fall from here reaches OCTU’s buffer after 11.2% and SIXO’s after 8.0%. 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.
