In March 2016, Visium notified shareholders that Visium was being investigated by the United States Department of Justice and the U.S. Securities and Exchange Commission regarding the company's actions in regard to their Credit Opportunities Fund which had been shut down in 2013. The investigation led to large customer withdrawals. Later in June, three traders at the firm were charged with securities fraud. Sanjay Valvani and Chris Plaford were indicted for insider trading while Plaford and Stefan Lumiere were accused of inflating the value of the Credit Opportunities Fund.
