Stocks on Surveillance in June 2026: ESM, ASM & GSM

To protect investor interests and ensure fair and orderly market activity, SEBI and stock exchanges continue to place select securities under enhanced surveillance frameworks. These measures are designed to control excessive price volatility, reduce speculative activity and bring additional caution in trading.

Depending on the surveillance category, restrictions may include tighter price bands, trade-to-trade settlement, periodic call auctions, weekly trading windows and higher margin requirements.

Enhanced Surveillance Measure (ESM) – Stage II

Under ESM Stage II, trading is permitted only in the Trade-to-Trade (T2T) segment. Daily price movement is restricted within a 2% band. Trades are executed only through Periodic Call Auctions on each trading day.

Graded Surveillance Measure (GSM) – Stage III

Under GSM Stage III, trading is allowed only once a week, generally on Monday or the first trading session of the week. Buyers are also required to deposit an Additional Surveillance Deposit (ASD) of 100% of the trade value.

Additional Surveillance Measure (ASM) – IBC Framework

The ASM-IBC framework applies to companies undergoing proceedings under the Insolvency and Bankruptcy Code. Trading in such securities is restricted to weekly sessions, usually on Mondays or the first trading day of the week.

Investors should review these surveillance restrictions carefully before placing trades in such securities.
