Stock ETF Promise Index

An index fund promises its index, less its fee. The test is one year against an ETF tracking the same index, after the difference in the two fees. Within half a point is tracking; past one and a half points it did not. 1,671 funds are not measured: no other ETF tracks the index it names, so its tracking cannot be measured (909); it names no index it tracks (758); it and KEMX, the ETF it is measured through, are measured only against each other and are 3.67 points apart after fees, so which one missed cannot be told (1). The category's Promise Index leads with the share of its measured funds that Delivered, with the share of its measured net assets they hold beside it. The order is net assets, largest first. The list sorts one published number, with no scoring or weighting. Every one of the 1,744 stock ETFs ETFIQ covers is eligible. The window on the table: 1 year, Oct 27, 2025 to Oct 27, 2026.
