Insider trading refers to the trading of a public company’s stock or securities (such as bonds) by the employees or the members of the organization at different levels withholding price-sensitive information which has not been made public yet. In this, we talk about the Rajat Gupta case. In 2010, Raj Rajaratnam, a Sri Lankan hedge fund manager was accused of insider trading when Mr. Gupta had tipped him off regarding investment in Goldman Sachs.
