Yacktman achieved his success by paying reasonable prices for companies that produce gobs of free cash flow. Recently, he has been adding to positions in Avon Products ( AVP ), Coca-Cola ( KO 1.39% ), and PepsiCo ( PEP 2.26% ) ; the three companies now make up more than 20% of his portfolio. Yacktman's confidence should make long-term investors take a closer look at these three companies.
