Dinning joins the discretionary investment manager from Coal Pension Trustees where he was head of investment strategy across the UK’s £20bn coal industry pension schemes.
He will be a part of Waverton’s asset allocation committee and direct the external communication of the firm’s investment views to private individuals, charities and institutions.
In addition, he will be responsible for co-ordinating the firm’s top-down investment strategies and mentoring younger members of the investment team.
Dinning has more than 30 years’ City experience having worked for firms including UBS Warburg, Merrill Lynch and Kames Capital across London, Hong Kong, Edinburgh and New York.
Andrew Fleming, Waverton chief executive, said: “Having worked with Bill in establishing a great asset allocation track record at Kames, I am thrilled to have someone of his calibre join the team here at Waverton.”
Dinning’s hire follows that of Jennifer Fisher as head of equity research in May.
Fleming added: “William will help strengthen our investment capabilities even further, and is an important hire at a time when firms will need to generate more of their own research in the post Mifid II environment.”
