Method

The 11 ETFs in the ai infrastructure and chips theme, of which 7 publish net assets, ranked on the most recent figure for each. Across the funds listed here the weight held in S&P 500 companies runs from 62.1% to 67.1%. Size is not a measure of anything a fund did. It is where the money is. 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.
