AMD's stock slide last year may seem bad, but it's not nearly as bad as it seemed during the summer. The processor giant's shares reached a nadir of $5.76 on Sept.1 after hitting a high of $10.16 on April 16.
Meanwhile, AMD said in October that it is looking to build on its edge in graphics technology while still trying to figure out how to capitalize on it.
