LT-ASM · ASM 4What does LT-ASM · ASM 4 mean?
BSE · Long Term Additional Surveillance Measure (ASM 4)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.Exchange notice · 2026-07-06
