Six portfolio managers have left billionaire Izzy Englander’s multistrategy hedge fund Millennium Management, according to a report by Bloomberg. The report cites an unnamed person as the source familiar with the matter.

Millennium partner Sebastien Mourot is among the departures, along with senior portfolio manager Nick Tan, portfolio managers Roland Beunardeau and Jens Wauters, and two associate portfolio managers, Nacer Bengelloun and Murat Bostan. All were based in Millennium’s London office, the report added.

The report noted that three of the employees who left had a technology, media and telecommunications focus, while Bengelloun covered consumer discretionary and Tan specialized in industrials and materials.
