After inclusion in the framework, stock filter circuit of 5 per cent is applicable from the date of inclusion in ASM, besides, requirement of 100 per cent margin to trade in such stock becomes applicable from the next trade date.
The securities which are placed under the ASM framework will be reviewed on a periodic basis, the NSE said in a circular today.
The review will be either for application of other surveillance measures like shifting of securities into trade-for-trade segment or exclusion from ASM, it added.
In order to enhance market integrity and safeguard investors interest, the Securities and Exchange Board of India and the exchanges have been introducing various enhanced pre-emptive surveillance measures such as reduction in price band, periodic call auction and transfer of securities to trade-to-trade category from time to time.
"Market participants may note that ASM framework shall be in conjunction with all other prevailing surveillance measures being imposed by the exchanges from time to time," the NSE said.
The exchange also noted that the shortlisting of securities under ASM is "purely on account of market surveillance and it should not be construed as an adverse action against the concerned company/ entity".
