A handful of longtime traders for Steven A Cohen left his firm in recent weeks, according to people familiar with the matter, continuing a stream of high-profile departures from one of Wall Street's most prominent hedge-fund firms.

Chandler Bocklage, a portfolio manager at Point72 Asset Management who had previously been Cohen's longtime research trader, and portfolio managers Anthony Chedid and Ted Orenstein left the firm this week, the people said. Tom Rabolli, another portfolio manager, and Steven Rosen, a fundraiser and recruiter who ran the firm's Boston office, also left in recent weeks.
