Extension of trading window closure to Immediate Relatives of Designated Persons: SEBI has extended the automated trading window closure mechanism to the immediate relatives of designated persons in listed companies to prevent insider trading during periods when unpublished price sensitive information (UPSI) is likely to be in their possession, particularly around the declaration of financial results. Stock exchanges and depositories are now required to implement systems to freeze the PANs of these immediate relatives at the security level during the trading window closure period.
