List of Stocks Under ASM

To enhance market integrity and safeguard investors’ interest, SEBI and Exchanges have been introducing several surveillance measures from time to time. Some of these pre-emptive measures include periodic call auctions, reduction in the price band, GSM, ASM, and transfer of securities to the Trade for Trade segment.

Today, we will be talking about Additional Surveillance Measures (ASM)—a surveillance measure introduced in 2018 to ensure a fairer and safer market environment.

ASM: Meaning

Additional Surveillance Measures (ASM) are specific limitations that are imposed on stocks experiencing high price fluctuations that are uncharacteristic of said stock. Such ASM stocks are further classified into long-term or short-term ASM frameworks based on objective criteria:

• High Low Variation
• Close to Close Price Variation
• Market Capitalisation
• Volume Variation
• Client Concentration
• Delivery Percentage
• No. of Unique PANs
• Price-to-Earnings (PE) Ratio

Applicability of Long-term ASM

Below we list some of the criteria that shall be applicable for the shortlisting of stocks in the Long Term ASM Framework.

High-Low Price Variation 

• In the previous 3 months, corporate action adjusted-price variation exceeds (150% + Beta of the stock * Nifty 50 variation), 
• The top 25 clients account for 25% of the combined stock trading volume of NSE & BSE in the past 30 days, and
• Market Capitalisation exceeds Rs. 100 crores as of review.

Close-to-Close Price Variation 

• Corporate action adjusted price variation in the last 60 trading days exceeds (100% + Beta of the stock * Nifty 50 variation), 
• The top 25 clients account for 25% of the combined stock trading volume of  NSE & BSE in the past 30 days, and
• Market Capitalisation exceeds Rs. 100 crores as of review.

Or

• Corporate action adjusted price variation in the last 365 trading days exceeds (100% + Beta of the stock * Nifty 50 variation), 
• High-Low Price Variation exceeds (200% + Beta (B) of the stock * Nifty 50 variation), 
• The top 25 clients account for 25% of the combined stock trading volume of NSE & BSE in the past 30 days, and
• Market Capitalisation exceeds Rs. 500 crores as of review.

Volume Variation

• The average daily volume is equivalent to at least 10,000 shares in a month, 
• Monthly volume variation exceeds 500% of average daily volumes in the preceding 3 months, 
• The top 25 clients account for 25% of the combined stock trading volume of NSE & BSE in the past 30 days, 
• Average Delivery is below 50% in the last 3 months,
• Close-to-Close price variation in the last one month exceeds (50% + Beta of the stock * Nifty 50 variation), and
• Market Capitalisation exceeds Rs. 500 crores as of review.

Exemption: Average Volume of Bulk or Block Quantity / Security greater than 50%.

However, the following securities shall be excluded from the ASM List:

• Securities already under Graded Surveillance Measure (GSM)
• PSEs and PSBs
• Securities on which derivative products are available
• Securities already under Trade for Trade segment

After completing 90 calendar days in the Long-term ASM Framework, securities are eligible for a stage-wise exit from the framework every week.

ASM Stages

Stocks are subjected to stage-wise surveillance action after inclusion in the ASM framework, which we explain below.

Additionally, ASM stocks cannot be pledged or used for margin trading. Intraday leverage (MIS/BO/CO) is not allowed on ASM stocks. These stocks are also subjected to a 5% circuit filter to restrict price volatility. The benefits of all corporate actions, including bonuses, dividends, stock split, etc., are passed on to the shareholders, even if it’s an ASM stock.

Significance of ASM Listed Stocks

The purpose of introducing an ASM framework on listed stocks is to alert investors about the high volatility experienced in them, which should not be the case in the normal course of business. It is also a means of advising investors to conduct due diligence before investing in ASM stocks.

However, the imposition of ASM on stocks should not be construed as an action against the company. Instead, investors must realise that ASM applies to stocks solely for surveillance purposes.
