(Bloomberg) Sanjay Valvani helped Jacob Gottlieb build his Visium Asset Management into a hedge fund that at its peak managed $8 billion. Now he has put its future in doubt.
Valvani, 44, was accused on Wednesday of insider trading and reaping more than $32 million from trades in drug companies using secret tips, according to federal prosecutors. Valvani, a money manager and a top lieutenant of Gottlieb, was one of four people, including two former Visium employees, charged with securities fraud.
