BSE updates the list of securities under the Enhanced Surveillance Measure (ESM) framework. Certain securities move to Stage I or exit the framework effective August 20, 2026. Securities qualifying for the measure shift from the Rolling Settlement segment to the Trade-for-Trade segment effective August 21, 2026. These securities attract a minimum 100% margin on all open positions as of August 20, 2026, and on new positions from August 21, 2026. Securities shifting to Stage II operate under a 2% price band with Periodic Call Auction effective August 20, 2026. The exchange reviews these securities periodically. This framework operates alongside other existing surveillance measures. The shortlisting of securities does not constitute an adverse action against the company.
