In the stock market, you might have heard about ASM, which stands for Additional Surveillance Measure. It’s a framework that helps regulators monitor and manage stocks that show unusual trading patterns. This blog will explore what ASM is, how it affects stocks, and how it differs from GSM (Graded Surveillance Measure). Whether you’re new to investing or looking to understand these measures better, this guide will provide clear and simple explanations to help you make informed decisions.
Additional Surveillance Measure (ASM) Overview
ASM, or Additional Surveillance Measure, is used in the stock market to monitor stocks with unusual trading behaviour. If a stock shows erratic price changes or high trading volumes, it may be put under ASM. This means the stock might face extra rules, like higher margins or trading limits, to control its activity.
The goal of ASM is to make sure that any unusual trading is checked carefully to prevent market manipulation. By understanding ASM, you can be aware of which stocks are under extra surveillance and adjust your investment choices to avoid potential risks.
ASM List in Stock Market
The ASM list is a special list of stocks that are under Additional Surveillance Measure. When a stock exhibits unusual trading patterns or high volatility, it gets added to this list. The purpose of the ASM list is to keep a closer eye on these stocks to ensure fair trading. Stocks on this list may face stricter rules, such as increased margins or trading limits, to prevent any potential market manipulation.
Investors can check the ASM list to see which stocks are currently under extra scrutiny. This information is usually available on the websites of stock exchanges like NSE or BSE. Knowing which stocks are on the ASM list can help investors make informed decisions and avoid stocks that might be facing additional risks.
By staying updated with the ASM list, you can manage your investments better and be aware of any extra precautions you may need to take.
