Gwyther, who was involved in the discussions preceding the creation of the indices, replaces Mike Lenhoff who retired at the end of last year. He has been an active member of the committee for more than 15 years.
Gwyther said: “This appointment is a challenge that I relish. There is much of importance on the agenda as we look to ensure the relevance and usefulness of the private investor indices can be maintained.”
He will chair his first meeting on 28 February, although will be speaking at the next Apcims Investment Conference two days before.
Apcims represents 174 firms, including 112 private client investment managers and stockbrokers, and 62 associate members, running over £500bn of the country’s wealth.
Jason Baxter, Apcims’ head of investment and member services said: “Gwyther retains a wealth of knowledge regarding the private client community and performance measurement, as well as an understanding of the key issues faced by the indices committee. The committee is definitely in a safe pair of hands.”
