If such a big company is priced so low it may signal an opportunity. It is similar with GE now. But there is always the risk of its price continuing down. AMD could have failed to deliver better products and continued to struggle. You won the bet, congrats, but don't think you will be so lucky with other stocks. And don't forget to actually sell the AMD to realize profits at some point. Unrealized profit is, well, unrealized.
