Ken Heebner, America's Hottest Investor

(Fortune Magazine) -- The best mutual fund manager around - a.k.a. Ken Heebner of Capital Growth Management - looks restless. He is sitting in a conference room at Goldman Sachs's Boston office, listening to a young analyst pontificate about all the trends he thinks will sweep the markets in coming years. Oil demand outpacing supply. The rapid growth of agriculture. The increased sway of sovereign wealth funds. And on and on.

Heebner couldn't care less. His flagship fund, CGM Focus (CGMFX), has already made a killing on energy and agriculture, and Heebner has no patience for the pet theories of this or any other analyst (or economist or strategist). "I want information, not opinions," Heebner will later tell me. Then, just as the meeting is looking like a washout, Goldman analyst Marc Fox lets something slip that starts Heebner's brain whirling.
