It's interesting to point out that the market is continuing to basically not respond to this at all: https://finance.yahoo.com/quote/AMD?p=AMD (click it to the 5 day view, news was released yesterday), despite the fact this has been reasonably widely reported. Bear in mind this was reported yesterday before the transient rise in AMD's value, which has since fallen back. I'm not an expert but AMD's chart looks pretty typical of a normal week to me, not like a chart of a newly-reported disaster. Looking at the one month view, volume doesn't seem all that abnormal either. If they took a short position, they're not making any money, and if they took this out on options they're currently on track to lose it all.
