What is ASM?

In order to enhance market integrity and safeguard the interest of investors, The Securities and Exchange Board of India (SEBI) and Exchanges have introduced Additional Surveillance Measures (ASM) on securities with surveillance concerns based on objective parameters such as  Price / Volume variation, Volatility etc. (refer to this FAQ of NSE)

The following points are to be noted when the scrips come is ASM:
  1. The scrip will be categorized as Trade to Trade settlement and will not be eligible for BTST. 
  2. You’ll be able to Buy the shares in Delivery Only (CNC). That means Intraday/CO/BO will not be allowed.
  3. The haircut of the scrips coming under ASM will be 100%, i.e., you’ll not receive any collateral amount for pledging ASM scrips.
