His Point72 Asset Management, which attracted $5 billion in outside capital last year in a comeback for the hedge fund investor, is seeking to raise an additional $1 billion between May 1 and September, according to people familiar with the matter. The firm was one of 2018’s biggest hedge fund launches when Cohen returned to the industry after a two-year ban from managing other people’s money. His prior firm, SAC Capital Advisors, pleaded guilty to securities fraud and paid a $1.8 billion fine. Cohen wasn’t charged with wrongdoing.
