Katy Gladstone, co-head of Henderson Global Investors’ multi-manager range has left her post following a sabbatical. She was to return last month, but Henderson has confirmed she will not come back. Gladstone joined Henderson as a research assistant in 1999 and progressed through fund analyst and fund manager roles. In 2007 she became co-head of multi-manager investments at the group, alongside Bill McQuaker. McQuaker continues to manage the multi-manager range and is supported by a team of analysts and researchers. Gladstone took a sabbatical to travel.
