Sour grapes
This is just a group of opportunists looking to cash in on AMD's production issues. Anyone with a clue about the PC industry knows AMD has a history of production issues so to expect them to deliver a new APU design on their projected timeline which is clearly stated subject to change... and which has never in the past two decades actually happened, is either naïve or a huckster looking for jackpot justice.
Every single 10Q and other required AMD corporate financial statement has the required disclaimer about future stock value and performance. I personally have lost thousands on AMD stock due to their execution issues but I didn't try to bamboozle the judicial system into rewarding me for my faith in AMD to deliver products on time.
You know before you invest that there is a very high risk AMD will not deliver on time - especially with new tech. The investors took their chances and they were wrong. Now they want to be rewarded for betting on the wrong company. That's not how it works in the real world.
