The capital markets regulator SEBI today asked investors to remain calm and exercise due diligence before reacting to reports such as that by US-based short seller Hindenburg Research. The US short seller alleged on Saturday that the head of Securities and Exchange Board of India (SEBI), Madhabi Puri Buch, previously held investments in offshore funds also used by the Adani Group. Ms Buch, in a separate statement, said that her investment in offshore funds mentioned in the Hindenburg report predates her appointment at SEBI by two years. Sakshi Bajaj reports.
