"Then again Warren has an interesting history with energy stocks. Over the years that I have owned BRK he has had a position in XOM, COP, PSX, CVX and now OXY. He sold XOM almost as fast as he bought it, took a significant write-down in COP, built up a 14% position in PSX only to sell the entire position WAY TOO EARLY, seems to sell bits and pieces of CVX every quarter and now is no longer adding to OXY."

You forgot PetroChina, which was approximately a 10 bagger. ;-)
