New Delhi, Oct 10 (ANI): The country's capital markets regulator, Securities and Exchange Board of India (SEBI) is all set to formulate a new set of rules vis-a-vis disclosures by listed companies to curb errant trading of scripts such as insider trading and over or under rated deals. SEBI Chairman UK Sinha stated this in New Delhi on Thursday. He was speaking to the mediapersons on the sidelines of an event hosted by the PHD Chamber of Commerce and Industry. India, at present does not have any formal rules meant for dealing with the annulment of trades. Instead, stock exchanges across the country have devised their own guidelines. Recently, the SEBI took several measures to protect the interest of the investors.
