Regret to say, but not a valid harmonic pattern. I wouldn't trade such a pattern ... harmonic patterns are ONLY a success when accurately measured up to the harmonic pattern rules. If you were to be right, this would be because of the support (X and D form a strong support line), which makes more sense (and the overall market sentiment that reversal for Tech stocks is about to happen). Good luck!
Nevertheless, in my humble opinion fair price of AMD is around 9 USD. The premium is only be accepted in a bullish market.
I was short on this (11.4 --> 10.9 USD), but lost interest in this stock. Micron Technology was a better option to short.
