Judge will be responsible for the management of GLG’s range of UK funds within the UK equities division headed by John White and Jason Mackay.
These include the £0.6bn GLG alpha select fund and the recently launched GLG UK select fund.
Judge joins the firm from Merrill Lynch where he was a managing director in the equities division.
White says: “We are delighted Nick has decided to join the team. He is a hugely talented UK specialist who I have known for many years, and have worked with previously at Morgan Stanley. His knowledge and insight are second to none, which has been demonstrated over a long period of time by the consistency of his performance-generating ideas.”
