Among stock market investors, none is more revered than Warren Buffett. He's been in the investing business since the 1950s, and one indicator of his success is that he is the second-wealthiest individual in the country, after Microsoft's Bill Gates.
The man doesn't just theorize, he puts his money where his investing beliefs are, and he has a track record of success to show how good those beliefs are and his skill at applying them. This is borne out by the growth in share price of his investment vehicle, Berkshire Hathaway (BRK.A:NYSE - commentary - research - Cramer's Take), shares of which trade for a lofty $88,000. (Buffett can be a bit eccentric, and one illustration is his refusal to split his stock, which is why two or three shares can cost more than a house.)
