• The $20 billion fund is trailing its peers in performance this year. 

Multi-strategy hedge fund Balyasny Asset Management saw a handful of departures in its stock-picking business earlier this month, according to people familiar with the matter. 

Four portfolio managers exited the $20 billion fund in early August, the people said, including Neville Irani, Colin Kronewitter, Ben Shapiro, and Jason Temerowski. 

A Balyasny spokesman declined to comment.

Some of the departures are said to be joining rival multi-strategy funds. 

Temerowski, a financials PM who has been at Balyasny since 2004, according to his LinkedIn bio, is said to be joining ExodusPoint. Ben Shapiro, a healthcare PM, is also said to have resigned to join another multimanager. 

Balyasny trails its peers in performance this year, returning 1.3% through July.
