HBS Entrepreneursclose window

Dean LeBaron (Batterymarch), HBS 1960, was with an investment services firm when he became interested in cutting-edge economic theories about portfolio management. One insight that captured his imagination was that a kind of complexity science based on computer models could be applied to portfolios to spread risk across many stocks with particular characteristics. He launched Batterymarch to apply these concepts to real-world investing and was among the first to use computer models to manage investment portfolios. Dean was also early to Latin America, the former Soviet Union, and China when investment opportunities opened there. He described his entrepreneurial experiences in a video interview at his home in New Hampshire in February 2001.
