Markets regulator Securities and Exchange Board of India is probing the huge build up of derivates positions in the Infosys stock. This comes amid whistleblower allegations of governance lapses made by a group claiming to be Infosys employees. Reportedly, put options for 1.8 million shares of the company were bought at a strike price of ₹740 per share just prior to the public disclosure of the whistleblower allegations. The stock fell below ₹640 on Tuesday, providing a potential gain of about ₹100 per share. This has raised doubts of insider trading. To clear the suspicions, it is important that a thorough probe be conducted so that investor confidence can be restored.
