Sure. I'd have to say you have never invested before.
They are? did you even look at the chart before you said that, NO! Case and point oct 09 the 5870 gets launched amd stocks jumps and stays solid through the whole fiscal year. That's a amd gpu division being competitive. So how is the gpu division doing now? Not very well aparently.
Did you say Microsoft? Really, that would never happen!!! ever
AMD was warned about their stock prices in the past. They have been threatened with becoming delisted, looks like they got away with it again.
