NEW YORK (TheStreet) -- Warren Buffett is considered the most respected and successful investor. Often called "The Oracle of Omaha" for his impressive investing prowess, he is among the world's wealthiest people.
Buffett studied under the legendary Benjamin Graham at Columbia University who had a major impact on Buffett's life and investment strategies.
Buffett is chairman of Omaha, Nebraska-based Berkshire Hathaway Inc (BRK.A) which he built from a textile company into a major corporation with a market cap over $200 billion. Under Buffett's leadership, Berkshire shares averaged a 21.4% compounded annual gain in per share book value from 1965-2006.
He follows a value investing strategy that is an adaptation of Graham's approach: Discipline, patience and value consistently outperforms the market. His moves are followed by investors worldwide. Buffett seeks to acquire great companies trading at a discount to their intrinsic value, and to hold onto them for a long time. He will only invest in businesses that he understands, and always insists on a margin of safety.Regarding the types of businesses Berkshire likes to purchase, Buffett has said,"We want businesses to be one that we can understand, with favorable long-term prospects, operated by honest and competent people, and available at a very attractive price." What follows are Buffett's top 25 holdings as of March 31, 2014.
