In an interview with Canada’s Business News Network, Validea CEO John P. Reese recently discussed how investors can profit from the strategies of history’s best money managers — and why so many fail to do so.

Reese says that following the approaches of great investors like Peter Lynch and Warren Buffett requires a cold, hard, unemotional look at a company’s financials and fundamentals, as well as the discipline to stick with the strategy during inevitable rough periods. Most investors, however, tend to pick stocks for more qualitative, emotional reasons, and they lack the discipline to stick with the strategy when the going gets tough, Reese says. He looks at how his Guru Strategies, each of which is based on the approach of a different investing great, work. In particular, he examines his market-beating Benjamin Graham-inspired model, which is based on the approach that “The Father of Value Investing” laid out more than 6 decades ago.
