And now that we're reading, here's some of Warren Buffet's worst mistakes:
http://finance.yahoo.com/bankin...-buffetts-worst-mistakes01. Conoco Phillips
Mistake: Buying at the wrong priceIn 2008, Buffett bought a large stake in the stock of Conoco Phillips (COP) as a play on future energy prices. However, this turned out to be a bad investment, because Buffett bought in at too high of a price, resulting in a multibillion-dollar loss to Berkshire.
02. U.S. Air
Mistake: Confusing revenue growth with a successful businessBuffett bought preferred stock in U.S. Air (LCC) in 1989 -- no doubt attracted by the high revenue growth it had achieved up until that point. The investment quickly turned sour on Buffett, as U.S. Air did not achieve enough revenues to pay the dividends due on his stock.
03. Dexter Shoes
Mistake: Investing in a company without a sustainable competitive advantageIn 1993, Buffett bought a shoe company called Dexter Shoes. Buffett's investment in Dexter Shoes turned into a disaster because he saw a durable competitive advantage in Dexter that quickly disappeared. According to Buffett, "What I had assessed as durable competitive advantage vanished within a few years." Buffett claims that this investment was the worst he has ever made.
