Summary
Brevan Howard, the $11.4 billion macro-focused hedge fund founded in 2002, has experienced the departure of Mike Graham, a long-tenured macro portfolio manager with nearly two decades at the firm. According to his LinkedIn profile, Graham—who joined Brevan Howard as a graduate recruit in 2007—is now subject to a non-compete agreement. Both the hedge fund and Graham declined to comment on the circumstances surrounding his exit.
Graham's departure marks a significant personnel transition for a manager who spent virtually his entire career at Brevan Howard, with the exception of one year of military service in the British Army. The timing of his exit arrives as the firm's flagship Master Fund has shown early signs of recovery, posting a 4.4% return in January 2026 after a sluggish 2025 that saw only 0.8% gains. This underperformance in 2025 contrasted sharply with stronger market conditions for hedge funds generally during that period.
The Graham departure occurs amid broader portfolio management restructuring at Brevan Howard. In January 2026, the firm reallocated Fash Golchin, a prominent trader previously running the external-capital FG Fund, to oversee the largest cash allocation from the Master Fund's $11.4 billion asset base. These internal shifts suggest the firm is actively repositioning its macro investment strategy and talent allocation to improve performance in its core fund.
Reports indicate Brevan Howard has been addressing performance challenges through selective portfolio manager departures, particularly in systematic macro strategies, alongside reductions in middle office staffing. The firm's macro fund faced headwinds in 2025 despite broader hedge fund industry strength, positioning these management transitions as part of a strategic recalibration aimed at restoring the flagship fund's competitive positioning.
