Market manipulation, pure and simple. AMD should have dropped a dime or so, not 19 - 20 percent this morning. Citigroup, the primary MM in this stock, is a corrupt investment bank and should have been left to die a few years ago by the US government like GS and MS.
Over-reactions to a mere penny miss. The MM in this stock have turned earnings time into a gambling casino not a real investment like it should be. Corrupt US trading practices never prevented by the SEC.
You are kind of ungrateful since there was no belly aching when AMD ran up to $4.80 riding hype and Intel's coat tails. If you are distressed today its only due to the boat leaving the dock without you aboard.
How many times can the exact same thing repeat itself, run up before financials down after the news before individuals such as yourself wise up and trade AMD as a stock that trades in a tight channel?
