27 Companies Change in BIST 100: New Additions and Exclusions

The Borsa İstanbul (BIST) 100 index underwent a significant rebalancing, with 27 companies removed from the list and an equal number of new companies added. The changes were announced in the first quarter of 2024 and were made to update the index in line with its market‑capitalization‑weighted structure. The rebalancing process is based on criteria such as market capitalization, liquidity, and sector representation. Companies that were removed had fallen below the established thresholds or failed to meet liquidity standards, while the new additions were selected for their growth potential and contribution to sector balance. Such adjustments aim to ensure that the index more accurately reflects the market conditions that investors encounter. The inclusion of new constituents may require passive investment vehicles—such as index funds and ETFs—to rebalance their portfolios. Changes in sector weights can directly influence investors’ risk profiles and returns, so strategies linked to the index should be reviewed and, if necessary, adjusted in light of the updated composition. This development underscores the dynamic nature of the BIST 100 and its efforts to adapt to evolving market conditions. The long‑term impact of the changes will depend on market participants’ reactions and the financial performance of the newly added companies. This is not investment advice.
