Maui, I don't see much of an upside to your theory, at least not today. There has got to be additional bad news on the horizon with their current products. They have a big write-off coming, and in 2008 they are only going to fall further behind in competitiveness, while being further disadvantaged with costs. They have also made promises of operational profits in Q3 2008, which I think is unlikely without big cost cutting.
On the other hand, there are a few catalysts that could take the stock higher. If AMD announced layoffs, it would indicate that they are serious about restructuring the company, and that could lift the stock. If Ruiz resigned, that would be seen as good news. If rumors of a takeover or acquisition came out, that would be seen as positive as well.
But as these things do not happen, AMD seems to have an inevitable future. They cannot sell their products without lowering prices further. And they can't sell tri or quad cores without pricing them well below Intel's, even though the larger die size will lower their margins.
I can't predict what will bail AMD out of this mess, but it won't be pretty. If you want to buy in, wait until the stock goes below $5. After the ATI write-off, the book value will drop significantly.
