Clemmie Vaughan will take charge in April this year after joining the company in 2005.
She will take the reins from Henry Maxey has been chief executive and chief investment officer for five years. He will retain the latter title.
Vaughan is currently head of Ruffer’s private client department and is a member of the executive committee and management board.
Jonathan Ruffer, chairman of the group, said: “Henry has successfully steered the business in its development over the last five years.
“This is Ruffer LLP’s third CEO since it started 22 years ago. Once again, it is an internal appointment, and a wholly appropriate development.”
He added: “I am right chuffed.”
When Jonathan announced his succession seven years ago, I headlined my vision ‘moving forward to stay the same’. The decision to divide the dual CEO-CIO role is a natural development of that vision.
The organisational challenges of our growth demand full time attention. At the same time, releasing more of my time for investment reflects the absolute importance of sound investment judgement within client portfolios.
