Surveillance Measures on Stocks – September 2025

To protect investors and keep the market fair, SEBI and stock exchanges put some checks on certain stocks. These include tighter price limits, special auction systems, or shifting the stock to the Trade-to-Trade segment. 

• Enhanced Surveillance Measure (ESM) Stage II: The stock will only trade in the Trade to Trade category, with a 2% daily price band. All trades will happen through Periodic Call Auctions on every trading day. 
   
• Graded Surveillance Measure (GSM) Stage III: The stock can be traded only once a week (every Monday or the first trading day of the week). Also, buyers must pay an Additional Surveillance Deposit (ASD) equal to 100% of the trade value. 
   
• Additional Surveillance Measure (ASM): If a company is under Insolvency Resolution Process (IBC), its stock will also trade only once a week (every Monday or the first trading day of the week).
