ASM Full Form

ASM Full Form

The full form of ASM in the context of the stock market is “Additional Surveillance Measure.” Stock exchanges employ this measure to closely monitor the trading activities of particular securities that exhibit atypical market behaviors or excessive volatility. 

The objective of ASM is to ensure that investors are protected from turbulent price movements and to maintain the overall integrity of the market.


What is ASM in Share Market?

Additional Surveillance Measure (ASM) is a framework set by stock exchanges to monitor and review the trading activities of particular securities closely. The initiative safeguards investors from extreme price volatility due to market manipulation or other unscrupulous activities. 

Under ASM, securities exhibiting abnormal price movements or inconsistent trading patterns are placed under enhanced surveillance to provide a safer and more transparent trading environment.

For instance, consider a scenario where a particular stock exhibits a sudden spike in trading volume and price without any substantial change in the company’s fundamentals or market conditions. 

Such abnormal behavior can trigger the stock to be placed under ASM. Once under ASM, there are certain restrictions and closer monitoring applied to the trading of this stock to curb any manipulative activities and protect the interests of investors.

How Does ASM Work?

The ASM framework operates by identifying securities that display abnormal trading behaviors and placing them under closer watch. 

This process involves several steps:

  • Identification: Stocks showing unusual price or volume movements are identified based on predefined criteria.
  • Listing: Identified stocks are listed under the ASM category, notifying investors about the enhanced surveillance.
  • Monitoring: Continuous monitoring of the trading activities of the listed securities is conducted to detect any manipulative practices.
  • Review: Periodic reviews are carried out to decide whether to continue or remove the securities from the ASM list.
  • Reporting: Regular reporting to the concerned regulatory authorities is done to ensure compliance and take necessary actions if required.

ASM Framework – ASM Stages

The ASM framework is structured into different stages, each with its surveillance actions. This systematic approach helps in managing the securities under surveillance effectively:

Stage 1: Initial identification and listing of securities under ASM based on predefined criteria.

Stage 2: Enhanced monitoring and imposition of certain trading restrictions to curb manipulative activities.

Stage 3: Further restrictions and closer scrutiny if the abnormal behavior continues.

Stage 4: Review and possible delisting from ASM if the security’s trading behavior normalizes.

Difference Between ASM And GSM

The primary distinction between Additional Surveillance Measure (ASM) and Graded Surveillance Measure (GSM) is that while ASM is directed towards monitoring specific securities showing abnormal trading patterns, GSM has a broader scope and is designed to tackle market-wide manipulative practices.

RestrictionsExplicitly applied to listed securities.Vary based on the assigned surveillance grade.
ReviewReviewed periodically to ensure effectiveness.Reviewed based on prevailing market conditions.

Types of ASM List

ASM framework typically comprises two major lists based on the level of surveillance required:

  • List 1: Securities that initially meet the criteria for enhanced surveillance are placed in this list.
  • List 2: Securities that continue to exhibit abnormal trading behaviors despite being under surveillance are escalated to this list for stricter monitoring.

In the initial phase, securities identified for abnormal behavior are placed in List 1 and subjected to certain trading restrictions and closer monitoring. If the unusual trading pattern continues, they are moved to List 2 for further scrutiny, where stricter measures are employed to ensure market integrity and protect investors.
