ETFIQ Downside Cover Score: GSEP scores higher
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
They do not reset together. OCTU has 10 days of its period left and GSEP has 361, so the two are not the same bet on the same months.
Where each one stands today
OCTU resets first, on Sep 30, 2026, 10 days from now; GSEP runs to Sep 17, 2027, 361 days. A fall from here reaches GSEP’s buffer after 1.5% and OCTU’s after 11.2%. 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.
