durability of investment ideas

Some think if an investment idea is well-known and seems obvious it can't be really good. In 1938, Fortune Magazine concluded "Several times every year, a weighty and serious investor looks long and with profound respect at Coca-Cola's record, but comes regretfully to the conclusion that he is looking too late." Since that time, Coca-Cola has grown significantly both domestically and around the world. It was not too late in 1938, and we believe it is far from that today. - From the 1Q 2010 Yacktman Quarterly Letter
