What is Enhanced Surveillance Measures (ESM)?

---

To control volatility in small-cap securities, SEBI has enforced Enhanced Surveillance Measures (ESM) for companies that have a market cap of less than Rs. 500 crores from June 5th 2023.

• The parameters to categorise securities under the ESM framework include high-low price variation and close-to-close price varitation.
• Securities of public sector enterprises and banks, and securities on which derivatives products are available will be excluded for the surveillance guidelines.

The ESM framework includes 2 stages:

Stage	Trade & Settlement	Price Band
I	* 100% margin applicable * Trade settlement is on Trade-to-Trade (T2T) basis * The security shall be placed under this category for a minimum of 3 months	Price band of: A. 5% B. 2% if the security is already under the 2% price band
II	* 100% margin applicable  * Trade settlement is on T2T basis  * Trading is permitted once a week and conducted through a Periodic Call Auction * The security shall be placed under this category for a minimum of 1 month	Price band of 2%

Only delivery-based trading (T+1 settlement) is permitted for stocks under the T2T segment; intraday trading is not allowed
