Summary
Balyasny Asset Management has hired Simon Costello, a senior FX options trader from Goldman Sachs, as a portfolio manager based in the firm's London office. Costello spent approximately eight years at Goldman Sachs before making the transition to the $28 billion hedge fund, where he will assume responsibility for portfolio management duties.

The recruitment reflects an ongoing pattern of senior talent movement from established investment banks to multi-strategy hedge funds. Costello's specialization in FX options trading—a sophisticated derivatives segment requiring deep technical expertise and market access—positions him to contribute to Balyasny's trading operations across multiple asset classes and strategies.

Balyasny's hiring activity has accelerated in recent months, as evidenced by the concurrent recruitment of David Brodsky from Citadel to bolster the firm's portfolio management team. These moves underscore the hedge fund's strategic priorities in expanding its London presence and building specialized trading capabilities among top-tier talent from leading financial institutions. For Costello, the transition from banking to hedge fund management represents a career progression common among accomplished traders seeking greater autonomy and alignment with performance-based compensation structures typical in alternative asset management.
