Graded Surveillance Measure (GSM): Meaning, Stages, Impact and Investor Guide

The Graded Surveillance Measure (GSM) is an approach adopted by Indian stock exchanges in coordination with the market regulator to keep a check on stocks that show abnormal fluctuations in their prices and poor financial health. The purpose of adopting the GSM approach is to protect investors from indulging in excess speculation. Depending upon the degree of risk involved, further surveillance and restrictions on stock trading will be imposed. Let’s read further in detail about graded surveillance measure.

What is Graded Surveillance Measure?

The Graded Surveillance Measure (GSM) is a surveillance system adopted by stock exchanges to detect stocks exhibiting unusual increases in prices, high volatility, or poor financial performance.

It works as a precautionary device to warn investors about any stock that may lead to risky trading behavior.

Inclusion of a stock under the Graded Surveillance Measure does not imply fraudulent conduct on the part of the firm. Rather, it warns investors to take precautions.

Why Was Graded Surveillance Measure Introduced?

The graded surveillance tool was adopted for purposes of investor protection and maintenance of order within the stock market environment.

Some of its main aims are as follows:

• Deterring speculation
• Retail investor protection
• Curbing market manipulation
• Improving market transparency
• Ensuring informed investment

This mechanism assists stock markets in monitoring those stocks which have been performing contrary to their intrinsic values.

How Does Graded Surveillance Measure Work?

With regard to the  graded surveillance measure, stock exchanges will conduct an evaluation of the securities listed using certain financial and market criteria.

Stocks that qualify for the GSM criteria can be classified into different levels of the GSM framework. According to their level, further restrictions may include increased margins, trade-to-trade settlements, or trading intervals.

The surveillance status of the stocks is subject to regular reviews, and they may be uplisted, downlisted, or delisted accordingly.

Stages of Graded Surveillance Measure

The multiple stages in the process of graded surveillance result in increasing levels of control. Stage

With each progressive stage of GSM, trading becomes increasingly limited and investors become more cautious.

Criteria for Inclusion Under GSM

Several factors must be taken into account by stock exchanges before a company’s stock can be subjected to the grading surveillance procedure.

Among these are the following

• Price rise
• Small market capitalization
• Poor financial performance
• High valuations
• Low net worth
• Unusual trading patterns
• Low liquidity and price volatility

Impact of GSM on Stocks

Where a stock has been classified for a graded surveillance measure, it will:

• Suffer reduced liquidity
• Experience increased margins
• Have reduced speculative involvement
• Face increased trading restrictions
• Receive more investor attention

Thus, trading volumes of the GSM stock will be reduced, and its price action will also experience reduced volatility.

How Does GSM Affect Investors?

The graded surveillance measure serves as an important warning indicator for investors.

While investing in a GSM stock, investors must:

• Go through the financial statements of the company.
• Do business analysis.
• Know the reason behind its classification as GSM.
• Consider any risk of illiquidity.
• Not invest purely based on upward price movements.

Difference Between GSM and ASM

While both GSM and ASM are forms of surveillance, they vary in terms of objective and constraints.

Both measures play an important role in promoting market discipline and safeguarding investors’ interests.

How to Check if a Stock is Under GSM?

Investors can determine if the stock falls under the surveillance through the graded surveillance measure list on the website of the stock exchange, which updates its GSM list from time to time.

It is prudent to verify if the stock falls under any form of surveillance before investments.

Investment Considerations for GSM Stocks

GSM investments demand prudence because while some securities might ultimately leave the realm of surveillance, others could stay in the restrictions domain for a longer time period.

Some of the areas investors should concentrate on are:

• Fundamentals of companies
• Growth in earnings
• Corporate governance
• Debt levels
• Future prospects of the business
