During the market turmoil in early August, losses snowballed. For some hedge fund traders, it was a scary time: sometimes as long as the boss patted them on the shoulder in the back, it meant it was all over. According to people familiar with the matter, at least six traders working for multi-strategy investment companies Millennium Management, Balyasny Asset Management, and BlueCrest Capital Management revealed that their positions were closed or their teams were shut down. It was a time when Japanese yen arbitrage trading was rapidly closing, and global markets were filled with tension over the US economy. According to people familiar with the matter, the trading team of Chiga Murayama, a senior portfolio manager who specializes in trading Japanese treasury bonds at BlueCrest, has been shut down. Murayama and team member Yosuke Motegi have left these positions. Ryan Fitzgibbon, who trades industrial and energy stocks at Millennium, left after losing money, and his Asian colleagues Shao Ying and Zachary Corones also left the trading team. Both of them operate index rebalancing strategies. It is reported that Balyasny's Hong Kong trader Mark Cox has also left. He claims to be a “shareholder” on his LinkedIn profile.
