50. Alaska : Bob Gillam
Bob Gillam founded McKinley Capital Management, an Anchorage-based institutional investor that oversees more than $7 billion in assets. Gillam, who studied at Wharton and then got an MBA at UCLA, started at brokerage firm Foster & Marshall before cashing out when the company was acquired by American Express.
He implemented quantitative computer models to develop a strategy based on the ages-old modern portfolio theory, in which investors examine historic returns and volatility of different asset classes to estimate future risk and returns. He remains president and CEO of the firm. Gillam, an outdoorsman, owns a hunting and fishing lodge on Alaska’s Lake Clark. He has been an outspoken opponent of the proposed Pebble Mine project, which would see the construction of a large, open pit copper and gold mine, due to environmental concerns.
