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 Corgi funds, so the difference between them is the terms rather than the house.
Where each one stands today
CMAY resets first, on Apr 30, 2027, 224 days from now; MAYC runs to Apr 30, 2027, 224 days. A fall from here reaches CMAY’s buffer after 5.7% and MAYC’s after 5.7%. 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.
