The Long-term Additional Surveillance Measure (LT ASM) is a regulatory framework introduced by SEBI and Indian stock exchanges to monitor and manage risks in stocks that exhibit continuous abnormal trading patterns. This framework is designed to protect investors and enhance market integrity by imposing stricter trading conditions on selected securities for an extended period.
Criteria for Inclusion in LT ASM
Stocks are selected for the Long-term Additional Surveillance Measure (LT ASM) list based on objective criteria jointly defined by SEBI and the exchanges.
These criteria include significant price swings (high-low and close-to-close variations over defined periods), abnormal trading volume fluctuations, high client concentration (such as the top 25 clients accounting for a large share of volume), differentiated market capitalization thresholds, low diversity among traders (few unique PANs), low delivery percentage, and extremely high or volatile price-earnings (PE) ratios.
Stages of LT ASM
LT ASM (Long-Term Additional Surveillance Measure) is applied in steps. As a stock moves through each step, trading restrictions become stricter to help control unusual price movements or speculation.
- Stage I: 100% margin requirement from T+3 days; price band may be reduced.
- Stage II: Further reduction in price band; continued 100% margin.
- Stage III: Additional price band reduction; continued 100% margin.
- Stage IV: Settlement on a gross basis (trade-to-trade), 100% margin, and a restrictive price band (e.g., 5%). For derivative stocks, new contracts are not issued, and existing contracts are settled as per expiry.
