Without a doubt America's most successful investor, Warren Buffett released his much anticipated annual letter to his shareholders about Berkshire Hathaway's performance, reporting a net worth gain in 2006 of $16.9 billion, an 18.4% increase.
With Berkshire Hathaway sitting on $42 billion in cash, shareholders and investors alike pour over his missive every year, searching for guidance on where and how Buffett finds value.
Buffet has a knack for finding the overlooked gems -- company's like Israel's Iscar and South Korea's POSCO are among his more recent bets. Along with POSCO, Buffett added four other new companies to his master list: Conoco Philips , Johnson & Johnson , Tesco and U.S. Bancorp .
In the first two videos, Liz Claman -- who had an one-of-a-kind interview with Buffett in Omaha last year -- provides an overview of Buffett's letter and a look at his search for an "emotionally stable" understudy.
The final video in our series examines how Berkshire Hathaway soared 56%, driven by improved insurance results and what the Oracle of Omaha calls a "large dose of luck." Joe Lampel, Professor of Strategy, Cass Business School, shares his insights with Michelle Caruso-Cabrera on "Worldwide Exchange."
