No companies changed places within the top 10. The current board is live, so it is compared with a month-end snapshot at the close of September 2026 rather than a completed month.
Compares today's ranking with the close of September 2026, the most recent month the archive holds. Positions here move with live prices, so a difference against that close is not a completed month's result.
