How fresh are these utilities prices and rankings?

Market caps, prices, and day changes come from the daily universe build (last refreshed 2026-08-17 05:37); 1-year returns come from the performance-rankings build (measured to 2026-08-14). A stock without a price or return history says so rather than showing zero.

Methodology. Rankings are by market capitalization from the daily universe build (last refreshed 2026-08-17 05:37) — prices and day changes carry the same stamp, not live quotes. 1-year returns come from the performance-rankings build (measured to 2026-08-14); a stock without return history says so.
