Two hedge fund brothers who jointly ran long-short equity strategies at Steve Cohen's SAC Capital and then Caxton Associates before starting their own European equities manager in 2008 have parted ways after 15 years.

Abe and Jack Eisenstat co-managed a European long/short equities fund at SAC between December 2000 and March 2003, before switching to become managing directors at Caxton and running a similar fund until March 2008, when they left to set up Dabroes Management.
