Barry Schachter left his post as Balyasny Asset Mangement's risk manager in July.
Balyasny has no current plans to replace Schachter. Chief operating officer Taylor O'Malley has taken over day-to-day responsibility for risk management, while founder Dmitry Balyasny remains in charge of risk management overall.
Schachter joined Balyasny just last summer, after spending two years as the chief risk manager at SAC Capital Advisors, the same role that he previously held at Caxton Corp. Schachter's plans could not be learned.
Balyasny experienced a deep drawdown last summer, but ended the year up about 5% on a composite basis.
