(Reuters) - Billionaire investor Steven Cohen"s Point72 Asset Management has suffered a nearly 15% loss this year due to a sudden surge in the shares of video-game retailer GameStop Corp, the New York Times reported nyti.ms/2YiotoW on Wednesday. The losses at Point72, which manages nearly $19 billion in assets, came in part from its investment in hedge fund Melvin Capital Management, which had made a massive bet against GameStop, the report said. But as GameStop soared 700% over the past two weeks, boosted by increased interest among amateur investors, Melvin faced sudden losses. One of the rescuers was Cohen’s hedge fund, which has roughly $1 billion under management with Melvin, NYT said. Point72 decided to add $750 million, Melvin said on Monday, besides accepting an investment of $2 billion from Citadel, the Chicago-based hedge fund led by Ken Griffin. Point72 declined to comment when contacted by Reuters. A spokesman for Melvin, founded in 2014 by Gabriel Plotkin, said the fund has closed out its position in GameStop and repositioned the portfolio.
