StokTrib is a holdings-based portfolio attribution system that allows clients to identify and isolate performance returns that can be attributed to manager skill rather than style. The technology behind StokTrib helps the institutional consulting and investor communities to make optimal decisions as it relates to manager selection and on-going manager monitoring. In December 2012, StokTrib was acquired by eVestment from Cainsoft. The valuation of StokTrib was undisclosed. Other terms of the deal were not released.
