Gartmore’s Investors Flee as Star Fund Managers Quit

Roger Guy and Guillaume Rambourg, Gartmore Group Ltd.’s two star managers, won European fund of the year at a black-tie gala at London’s Grosvenor House Hotel on Jan. 21. Ten months later, both have quit and the company is considering putting itself up for sale.

Rambourg left in July and Guy, 44, said yesterday he will retire at the end of the year, leaving investors in Gartmore’s December initial public offering nursing a 51 percent loss. Gartmore’s announcement that it’s weighing a sale underscores the vulnerability of money managers that rely on individual “star traders,” analysts said.
