 In 1989, the Commission des Opérations de Bourse (COB, the French stock exchange regulatory authority) conducted an investigation of whether Soros's transaction in Société Générale should be considered insider trading.Soros had received no information from the Société Générale and had no insider knowledge of the business, but he did possess knowledge that a group of investors was planning a takeover attempt.Initial investigations found Soros innocent, and no charges were brought forward.
