Two proprietary traders from the London division of Goldman Sachs Principal Strategies, the bank’s secretive equities arm that trades its own capital, are leading a 10-strong team to start a fund with the backing of Sweden’s largest hedge fund firm.

Daniele Benatoff and Ariel Roskis have set up a new company and will launch an event-driven hedge fund in the second quarter, according to several people familiar with the situation. It will receive $300m in seed capital from Brummer & Partners, a $10bn Stockholm-based manager, one of the sources said.
