BSE updates the list of securities under the Enhanced Surveillance Measure (ESM) framework. Certain securities move to lower stages or exit the framework effective May 19, 2026. Securities qualifying for ESM shift from the Rolling Settlement segment to the Trade-for-Trade segment effective May 20, 2026. These securities attract a minimum 100% margin on all open positions as of May 19, 2026, and on new positions created from May 20, 2026. Securities shifting to Stage II face a 2% price band and periodic call auction requirements effective May 19, 2026. The ESM framework operates alongside other existing surveillance measures. Shortlisting under ESM results from market surveillance and does not constitute adverse action against the company.
