Stock Exchange has introduced ASM mainly for controlling Speculation (Trading) in the stock.
ASM includes 2 basic points
1) Circuit Filter 5%
2) 100% margin on open positions of stock.It is just like a T2T.
You can not do Intra day trade in the stock. It means that you have to pay full amount when you buy the stock and you can sell stock only if you have in demat account.
No speculation (Trading) is allowed in the stock. More clearly, some Brokers gives credit facilities for their client by keeping 35% OR 40% margin . Now it is compulsory to keep 100% margin.
Some people are confused about 100% margin concept. If you have paid full amount of stock, then No margin is required. This 100% margin concept is for speculators (Traders) who do not pay full amount of stock and avails credit facilities from their Brokers.
To control this speculation (Trading), Exchange has newly introduced ASM. People are having confusion about ASM because it is new. In coming days ASM will be familiar like T2T.
That is why NSE write Trading is disabled in these stocks from 04.06.2018. It does not mean that stock will not trade from 04.06.2018 on Exchange. It means Speculation (Trading) on Margin in these stocks is disabled from 04.06.2018….
Also Once these stocks are sold, Credit will be received as in Normal Course.
I think this will help you to clear the concept of ASM…
ASM is also known as Graded Surveillance Measure.
SEBI introduced the measure to keep a tab on securities that witness an abnormal price rise that is not commensurate with financial health and fundamentals of the company such as earnings, book value, price to earnings ratio among others.
Why did SEBI bring in the measure?
The underlying principle behind the graded surveillance framework is to alert and protect investors trading in a security, which is seeing abnormal price movements. SEBI may put shares of companies under the measure for suspected price rigging or under the ambit of ‘shell companies’. The measure would provide a heads up to market participants that they need to be extra cautious and diligent while dealing in such securities put under surveillance.
How the Graded Surveillance Measure works?
Once a firm is identified for surveillance it goes through six stages with corresponding surveillance actions and the restrictions on trading in those securities gets higher progressively. In the first stage the securities are put in the trade-to-trade segment (meaning no speculative trading is allowed and delivery of shares and payment of consideration amount are mandatory). A maximum of 5% movement in share price is allowed.
In the second stage, in addition to the trade-to-trade segment, the buyer of the security has to put 100% of trade value as additional surveillance deposit. The deposit would be retained by the exchanges for a period of five months and refunded in a phased manner.
In the third stage, trading is permitted only once a week ie every Monday, apart from the buyer putting 100% of the trade value as additional surveillance deposit.
In the fourth stage, trading would be allowed once a week and the surveillance deposit increases to 200% of the trade value.
In the fifth stage, trading would be permitted only once a month (first Monday of the month) with additional deposit of 200%.
In the sixth and final stage, there are maximum restrictions.
Trading is permitted only once a month at this stage, with no upward movement allowed in price. Also, the additional surveillance deposit would be 200%.
Will securities remain permanently in the Graded Surveillance list?
There would a quarterly review of securities. Based on criteria, the securities would be moved from a higher stage to a lower stage in a sequential manner.
What are the points small investors should keep in mind about the Graded Surveillance Measure?
As and when a security is shifted to various levels of surveillance, it is publicly announced on a daily basis on BSE and NSE websites as well as through circulars to the stock brokers. Moreover, the exchanges can also appoint independent auditors to audit the books of accounts of these companies and do forensic audit, wherever needed.
This indirectly may also be an indication that the sudden rise in either the volumes traded or the price increase are not commensurate with the fundamentals of the said companies and hence small / retail investors are protected from getting stuck in such stocks inadvertently on some wrong advice.
The only challenge for the small investors is that these announcements are often made at very short notice and implemented from the next day itself thus giving those who have already entered the stock less than adequate time to exit it. Of course, there is also potentially another risk. For example, even if time is given, the stock might crash next day on the news, triggering the lower price circuit and leaving no exit opportunity.
