Surveillance Measures
Price related/sensitive news/announcements (business plans are excluded) that have not been intimated to Exchange have a significant impact on the prices / volume of the security and hence it is essential to verify the accuracy or otherwise of the same so that investors can take informed decisions.
Further, in cases where there is a spurt in price and/or volume without any major corporate announcement, clarification is sought form the company and the reply is then disseminated to the market through Exchange website.
The aforesaid process is carried out based on pre-decided criteria and in coordination with other National Exchanges.
