Method
Weight overlap is the sum of the smaller weight of every security two funds share, from their own filings. ETFIQ computes it for every pair on the desk. The ranking is the published field sorted, nothing else: no scoring, no weighting and no view on any fund. Every fund ETFIQ covers in this category is eligible, including funds that have closed, because leaving them out would flatter the category.
