How this is computed
It is a place in a set, not a rating or a recommendation.
ETFIQ calculates every figure 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 figure is an ETFIQ calculation with distributions reinvested.
