Having served on Jupiter’s board for nine years and having worked at Jupiter for 15 – including five years as chief investment officer. Together with Algy-Smith Maxwell, he has been responsible for creating and managing the Merlin range since it was launched in 1992.
Liz Airey, chairman at Jupiter, thanked him for his commitment to the twin roles.
In a statement to the stock exchange, she said: “John has made an exceptional contribution to Jupiter.
“At the same time as providing valuable perspectives at the board level, he has delivered strong performance over the long term to clients in one of Jupiter’s most important and successful investment strategies.
“We appreciate the dual role he has played for many years and support his decision to step back from his board responsibilities to focus solely on running his funds.”
Chatfeild-Roberts added: “I have greatly enjoyed my time on the board of Jupiter and its predecessor companies, helping in the overall success of the company. However, investing clients’ money in the Jupiter Merlin funds is the job I enjoy the most; I relish the opportunity to devote all my time to building on the performance track record we have established on behalf of our clients.”
