5 Stocks Excluded from Short-Term ASM Framework: What Investors Need to Know
Real Estate:The Short-term Additional Surveillance Measure (ST-ASM) is a regulatory mechanism introduced by SEBI and Indian stock exchanges to closely monitor stocks that exhibit unusual or sudden trading activity. Its primary goal is to safeguard investors and uphold market stability by applying temporary, tighter trading restrictions on highly volatile or speculative stocks.

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. The process is as follows:

- Minimum Period: A stock must remain in the Short-term ASM (ST-ASM) framework for a minimum period, typically 5 or 15 trading days, depending on the stage, before it becomes eligible for review and possible exit.
- Stage-wise Review: Stocks are reviewed after completing the minimum period in each stage. The review assesses whether the stock still meets the entry criteria for ST-ASM, such as abnormal price movements or high client concentration.
- Exit Criteria: If, during the review, the stock no longer meets the inclusion criteria for its current stage, it is eligible to move to the next lower stage. A stock in Stage I that does not meet the criteria can be fully exited from the ST-ASM framework.
- Ongoing Monitoring: The process is dynamic, with regular reviews ensuring that only stocks displaying recent abnormal trading patterns remain under ST-ASM.
