Wallace Weitz Profile

Portfolio manager of Weitz Value Fund, Weitz Hickory Fund and Weitz Partners Value Fund, which he started in 1983.

Wallace Weitz Investing Philosophy

Weitz's approach to value investing has evolved over the years. It combines Graham's price sensitivity and insistence on a "margin of safety" with a conviction that qualitative factors that allow a company to have some control over its destiny can be more important than statistical measurements, such as historical book value or reported earnings.
