Short-term Additional Surveillance Measure (ST ASM), a regulatory framework by SEBI and Indian stock exchanges, monitors stocks with sudden, unusual trading activity. It safeguards investors and ensures market integrity by enforcing temporary, stricter trading rules on volatile or speculative securities.
Criteria for Inclusion in ST ASM
Stocks are selected for the Short-term Additional Surveillance Measure (ST ASM) list based on objective, market-based parameters defined by SEBI and the exchanges. The main criteria include sudden abnormal price movements, sharp volume fluctuations, high client concentration, limited trader diversity, and volatility over a short period (typically 5 to 15 days), helping identify speculative or unusual trading activity for temporary, stricter monitoring.
Criteria for Exclusion from ST ASM
A stock may be considered for exit from the ST ASM framework if it no longer meets the inclusion criteria. It must stay in ST ASM for a minimum of 5 or 15 trading days, depending on the stage, before review.
Stage-wise assessments check if criteria like abnormal price movements or high client concentration persist. If unmet, the stock moves to a lower stage or exits Stage I. Ongoing monitoring ensures only stocks with recent unusual activity remain under ST ASM.
