Key Surveillance Actions for ASM Stocks

• Stocks under ASM may transition to the T2T segment based on eligibility.
• For details, refer to What are Trade-to-Trade or T2T stocks?

• 100% margin of the traded value is required, with no intraday leverage available (MIS/BO/CO orders are restricted).
• Exception: MIS is permitted for F&O stocks under Stage 1 of Short-Term ASM (ST-ASM). Refer to the NSE (PDF).

• Stocks under ASM cannot be pledged for margin purposes.
• If a pledged stock enters the ASM list, collateral margins will no longer be available. Investors can either unpledge or retain the stock in pledge without collateral benefits until it exits ASM.

SEBI's Graded Surveillance Measures (GSM)

• Corporate Actions Are Unaffected: Stocks under ASM continue to provide corporate action benefits, such as dividends, bonuses, and splits. Shareholders retain these benefits regardless of ASM status.
