BSE · Long Term Additional Surveillance Measure (ASM 1)LT-ASM is the joint SEBI/exchange framework for SUSTAINED abnormal price moves (contrast ST-ASM's 5–15-day spikes). Entry is beta-adjusted price variation versus the Nifty (e.g. 3-month high-low above 150% plus the stock's β × index move) along with client-concentration checks. Stages I–IV escalate from a 5% price band through 100% margin to Trade-for-Trade with an additional surveillance deposit. Practical meaning: the exchange still considers the price action abnormal — tighter bands and elevated margins continue even if another measure (like ESM) has lifted. A stock can sit under LT-ASM on both exchanges via either exchange's shortlisting; it is a preventive cost-of-speculation measure, not an adverse finding against the company.Criteria: High 3-month / 12-month high-low price variation, close-to-close price variation, client concentration, number of price-band hits, market-wide position limit and P/E — applied in graded Stages I–IV with escalating margin and price-band curbs.
BSE · Additional Measure for securities witnessing unusual price movementThe fast-track brake for ramps that GSM's quarterly cycle would miss. Practical meaning: the harshest liquidity curb short of suspension — in observed cases the stock trades only once a week (Monday) inside a tight band, so exiting a position can take weeks. Inclusion says the exchange views the move as manufactured, not discovered.Criteria: Special framework (BSE/NSE, introduced Nov-2025 vide BSE circular 20251107-56) for securities with unusual price movement not already under GSM — applies hard curbs fast: special margins, tightened circuit filters (down to 2%), trade-for-trade and restricted trading frequency (trading permitted only on the first trading day of the week in the observed cases). Reviewed periodically with inclusion/exclusion annexures.
