Well said. Sold NM at 16 and immediately bought more CF. Best bet in a long time. Look at what each has done since my buy/sell date in November.
Never, ever lose your profits, no matter what the company prospects are said to be IN THE FUTURE, as we don't know what the hell is going to happen IN THE FUTURE, and especially in the 2008 economy. I would sell GOOG or BIDU or CF if they lost 10%, and rebuy if deserving later. Any stock goes if profits are threatened!
