The Indian Stock Market is a dynamic landscape where investors are constantly in search of opportunities that coincide with their risk appetite and financial goals, leading to financial growth and wealth creation. However, in this bustling arena, regulators often attempt to maintain market integrity with numerous regulatory tools. One such significant regulatory tool used by regulators in this pursuit is the Additional Surveillance Measure (ASM). This article aims to shed light on ASM, understand its implications, and share a curated list of ASM stocks at present.
ASM, or Additional Surveillance Measure, is best described as a regulatory framework that is implemented by stock exchanges like the BSE (Bombay Stock Exchange) and NSE (National Stock Exchange) in India. The intention behind ASM is to identify securities with abnormal price movements or volatility to help investors understand what they are getting into. ASM is thus an essential tool put in place to enhance market integrity by safeguarding the interests of investors.
Stocks in the ASM list means that they are subjected to additional surveillance and monitoring, which often includes higher margin requirements and periodic reviews. This classification acts as a precautionary measure which helps mitigate potential risks that come with certain stocks. There is a predefined criteria for stocks to be included in the ASM list. These include price volatility, trading volumes, and overall market behaviour. Majorly, those companies which witness significant price movements and or display irregular trading patterns make the list.
As an investor, you must approach such ASM stocks with extreme caution and comprehensive fundamental analysis of the company like its financial health, profitability, debt levels, etc before arriving at any investment decisions. Equally important is to consider external factors such as economic trends, industry dynamics, and geopolitical events that can influence the company's performance.
ASM should not be interpreted as a list of fundamentally weak companies. It is advisable that investors analyse the reasons behind a company’s inclusion in ASM and look at its long-term potential. Other essential factors to consider while investing in such stocks are an evaluation of your own risk tolerance and diversification of your investment portfolio. Developing a clear exit strategy contributes to disciplined investing.
Lastly, it is crucial to keep in mind that all investments come with certain risks, some small while others are large, and that the past performance of a company is not an indication of its future trends. It is thus advised to consult with financial advisors who will help in conducting thorough research through prudent steps, especially when it comes to investing in stocks under ASM.
Now that we have gained knowledge about the ASM list of stocks and understood its different implications for investors, let us explore the list of 50 such stocks put under ASM scrutiny in the Indian stock market presently.
The list of stocks under ASM is essential in understanding the complex terrain of the Indian stock market and provides valuable insights for investors so that they make good investment decisions. It is however important to evaluate the list through detailed and comprehensive research on individual stocks which gives an idea of the companies and understand whether they align with your financial objectives, keeping the implications of the ASM in mind. Diligence and careful consideration are the most important factors to consider while navigating the exciting world of the stock market which can get quite unpredictable.
