What changed in this ranking
AI-generated summary by Rhea-AI, written on . How Rhea-AI works.
The current board is compared with the live month-end snapshot at the close of September 2026. Seagate Technology Holdings plc (STX) fell 39 places, from rank 71 to rank 110. Other technology fallers included Sandisk Corporation (SNDK), Western Digital Corp. (WDC), Arm Holdings (ARM), KLA Corporation (KLAC), Lam Research Corp (LRCX), Applied Materials, Inc. (AMAT) and Amphenol Corporation (APH).
ConocoPhillips (COP) was the strongest climber, rising 20 places from rank 105 to rank 85. Technology also supplied a group of climbers: SAP SE (SAP), ServiceNow, Inc. (NOW), International Business Machines Corporation (IBM), Shopify Inc. (SHOP) and Salesforce, Inc. (CRM) all rose.
Two debutants appeared on the current board: Vylor Inc. (VYLR) and Skydance Corporation (SKYD). VYLR appeared at rank 322, while SKYD appeared at rank 394. The lower end also includes companies absent from the September snapshot because of the universe boundary rather than a debut.
Warner Bros. Discovery, Inc. Series A (WBD) left the ranking after standing at rank 212 in the previous period. The broad movement below the leaders reflects these additions and departures alongside the genuine gains and losses above.
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.
