Top 10 — Utilities — history
Every change to this list, with the reason recorded at the time. 3 rebalances so far.
The Top 10 score is a published weighted sum of percentile ranks, rebalanced on the first trading day of each month. A list is a published formula and its output, not a recommendation. These rows span method versions 1 and 3 and 4 — the formula changed between them, so a score is only comparable within one version.
