Major Revision in BIST 50 and BIST 100 Indices Effective July 1, 2026

Borsa Istanbul has announced a significant revision to the BIST 50 and BIST 100 indices, effective July 1, 2026. According to the statement, some major stocks closely followed by millions of investors will be removed from the indices, while surprising new names will be added. This change is considered a critical turning point for portfolio managers and individual investors. As part of the revision, the stocks removed from the BIST 100 index include several companies previously notable for high trading volume and market capitalization. These stocks will be replaced by smaller-scale companies with high growth potential. Similarly, the BIST 50 index has undergone significant changes, with some well-known stocks being removed and new players entering the index. Experts note that such index revisions lead to automatic portfolio adjustments for passive investment funds and index trackers. Selling pressure is expected on removed stocks, while buying pressure is anticipated for added stocks. Investors should carefully assess the impact of these changes on their own portfolios. Details of the new list have been published on Borsa Istanbul's official website. Investors may take action to restructure their portfolios in line with this revision before July 1, 2026. However, it should be noted that index changes may cause short-term price movements. This is not investment advice.
