2. Graded Surveillance Measure (GSM) – Stage III

Trading allowed only once a week (every Monday or the first trading day of the week).

Buyers must pay 100% of the trade value upfront as an Additional Surveillance Deposit (ASD).

3. Additional Surveillance Measure (ASM)

These stocks are under Insolvency Resolution Process (IRP) as per the Insolvency and Bankruptcy Code (IBC).

Trading allowed only once a week (every Monday or first trading day of the week).
