What is ASM Framework?

When a security is put on the ASM framework, it means that additional rules govern the trading of that particular security.

Such steps exist to curtail excessive speculative trading and ensure that share prices reflect true values rather than mere rumours.Understanding ASM is crucial for any investor.

Therefore, keeping an eye on the ASM status of stocks is a critical element when making a sound decision to invest. Also read: Stock Market Index: Meaning and Importance

Different Types of Lists Used Under Additional Surveillance Measure

The additional surveillance measure (ASM in stock market) is a regulatory policy used to correct excessive volatility and maintain market integrity. Below is a breakdown of various types of ASM lists commonly found in the stock markets:

Price Bands

Price bands are upper and lower price limits for the trading of a particular security within one day. The concept behind this is to curtail drastic price movements of stocks daily that may cause panic selling or speculative buying.

Increased Margin Requirements

An increased margin requirement is a surveillance measure that requires investors to maintain a greater percentage of collateral against the transaction volumes. This prevents speculative trades and helps to reduce volatility.

Graded Surveillance Measures (GSM)

The different risk profiles that various stocks possess translate into different degrees of monitoring imposed upon them. For instance, some stocks may be showing peculiar price hikes or fluctuations without any significant changes in financials. The levels of surveillance and restrictions increase with the risk associated with the stock. This might even lead to trading suspensions if necessary.

Trading Restrictions

Some of the ASM-listed securities might have additional rules regarding intra-day trading limits or even bans on short sales. This is done to curb speculations and ensure that the price movements align with the market fundamentals. Also read: 4 Different Types of Stock Market Risk

Understanding the ASM Network: Stages of Surveillance in the Stock Market

Here are the various stages:

ASM Stages Description
Stage 1: Monitoring This is the foremost stage where the securities that exhibit abnormal activity in price or volume are placed under surveillance. At this stage, the primary purpose is to closely follow trading patterns to determine whether there is any manipulative activity going on.
Stage 2: Warning When the stock exhibits abnormal behaviour, it advances to this stage when stock exchanges alert investors of possible risks. This is an alert to investors who may not be aware of what may be lurking underneath.
Stage 3: Restriction This is the point when stringent measures are applied, such as wider margin requirements, lower position limits, and tight price bands. These are designed to decrease volumes of trades which can be conducted in the potentially troubled stocks.
Stage 4: Surveillance In extreme cases, stock exchanges may even place a particular security under direct surveillance. This is when all trading data and other consequences that involve harsher penalties in case of identification of any type of abnormality are subjected to close examination.
Stage 5: Continuous Monitoring & Adjustment The final stage involves continued monitoring to ensure that market stability and investor protection are upheld. Modification of the ASM measures is carried out as deemed necessary by the results of the ongoing monitoring and changing market conditions.

Impacts of ASM On Investors

Discussed below are some of the key impacts of ASM on the investors:

Restriction of Speculative Trading

One way through which the ASM affects speculators is by imposing stricter trading measures such as increased margin requirements and price bands. Such rules make speculative trades expensive, thereby forcing traders/investors to approach investment decisions more prudently after conducting a thorough analysis.

Enhanced Market Stability

By reducing excessive price volatility and speculative trading, ASM helps maintain market stability. This is beneficial for long-term investors looking for predictable market environments to make sound investment decisions.

Stock Liquidity Effects

While aiming to protect investors from abrupt stock price fluctuations, ASM may reduce liquidity for the monitored shares, potentially affecting the ability to execute large transactions quickly without significantly moving the market.

Investor Sentiment and Confidence

Confidence is boosted among investors when they see regulators actively involved in guarding against manipulation. This positive effect on sentiment is likely to attract more participants into the market, thus creating a vibrant trading atmosphere. However, labeling a stock as being under ASM might send wrong signals, thereby scaring some potential buyers away from such stocks. Also read: What is a Volatility Index?
