What is ASM List in Stock Market?

Investing in the stock (share) market contains a level of risk. These risks are uncertain and can cause significant loss to investors or capital erosion. While most stock trading risks arise due to its natural market behavior, there are still many areas where malicious activities affect the investor’s interest. Indian investors have already witnessed major stock market crashes like the Manu Manek and Harshad Mehta scams of the 1980s. It is one of the biggest scams of the Indian stock market that questioned the credibility of exchanges and authorities.

Along with such malicious activities, technical glitches and errors can also affect the stock market to misbehave. But whatever the case is, at the end of the day, investors have to suffer, and regulatory bodies face a hard time maintaining their credibility in the market. Therefore, neither of these two wants to witness such market behaviors. The Indian stock market regulatory authority has applied various safety measures like ASM or Additional Surveillance Measures to control unwanted activities.

What is ASM or Additional Surveillance Measure?

What is ASM List in Stock Market

ASM is one of the safeguard measures for investors. This mainly applies to stocks experiencing price fluctuations and having uncharacteristic stocks. The price fluctuation concept is called fair market value. The value gives the idea of a stock’s actual market price or the value at which the stock is supposed to be.

This price uses elements like the company’s performance along with other factors. Generally, the price of a company’s share in the market moves as per its market value. Also, price oscillation does not depend on the company’s fair value. This mainly occurs when traders manipulate the stock prices to make a profit by doing some speculative activities. 

In the Indian stock market, most traders are retail investors, and only a limited percentage of traders have the capabilities to affect the stock market and manipulate it for their profit. Thus, often it has been seen that these traders do some activities that help them earn a profit but have a negative impact on other investors’ portfolios. 

This is where ASM takes place, which works as a flagging mechanism to list shares that might have changes to move too erratically or are suspected to be affected by speculative activity. If a share gets listed in the ASM list, the price of a certain share affects certain limitations. It helps investors to think for a while before buying or selling such shares. 

Types of ASM
