Honestly, Baron I don't think the problem was the bottom line, it was the top line and margins that scared the investors. The ASPs were dragged down by the price war and Hector did not really give a good plan on how they were going to recover the lost margin.
I am speculating here, but the market community does not buy or sell on the report as much as they look for how that fits into the trend.... take that, together with Intel stating a bottoming out and I think they are getting nervous.
Intel's Q3 was not particularly good, but it was not horridly bad either as they exceeded and guided to within normal seasonal norms. The fear, I believe is that Intel's aggressive pricing and the product refresh may stagnate AMD's cash flow, which is not good considering they are in a take-over bid, trying to re-invest capital for expansion, and planning 2008 45 nm development.
This is what I mean by Hector's answer did not inspire confidence. If he points to two simple socket transistions as taxing the company, what is a take over, another new fab, and stiff competition as C2D increases it's visibility in the market going to do. AMD will have a tough 2007. If they can hold the cash flow, keep on schedule for expansion then that is the final big hurdle (in my opinion) to long term sustained health.
