Summary
Antoine Iskandar, a senior portfolio manager at Millennium Management, is leaving the firm to join rival Balyasny Asset Management, according to a report from Opalesque that cites Bloomberg. Iskandar is based in Zug, Switzerland. Before settling on the move, he held preliminary discussions about spinning out his own fund, a plan that will not proceed as originally envisioned under the Balyasny arrangement.

At Millennium, Iskandar managed more than $600 million. The publisher summary reports that his team suffered losses of tens of millions of dollars, though the available source material does not provide a precise figure or a full breakdown of performance over the period.

The departure is a further example of senior talent movement among large multi-strategy hedge fund platforms. Balyasny and Millennium are both prominent multi-manager firms that compete actively for portfolio managers with proven teams and track records. Allocators tracking manager stability at multi-strategy platforms may view the move as relevant to Millennium's team-level retention and to the capacity of Balyasny to absorb experienced PMs.

The primary source does not disclose details on compensation, the timing of the transition, or any capital commitments associated with the move. Further reporting may clarify these terms.
