Elmer-
While I agree with you on waiting for real facts, rumors can be good for alerting us to potential pitfalls and opportunities for investments. While I would not invest directly on these rumors, I may come up with a strategy to profit from it if the rumor becomes more than rumor. This is an advantage, so I welcome any information no matter how poor the source. I'll weigh it accordingly.
I have to admit, rumors like this make me more comfortable holding AMD shares long. I don't feel quite as anxious to sell. I'm more willing to see how things play out.
