AMBA completed a double-top and reached the target price. I agree we should get a bounce back, perhaps a 50% retracement from the recent fall. This would have the stock retesting the bottom of the channel (I draw it a little different) in the mid 90's.
I should add that I think this stock has seen a capitulation in exuberance with the enormous volume on 06/22/15. After the retest of the trend line in the 90's, I expect this stock will continue dropping and would be a great short at that point.
