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.
