They may not currently have the support pf WS but they had it in a big way. When you are as high flying as AMBA was and you burn WS then you pay and pay dearly and the pain can continue indefinitely. I agree with others here that until AMBA can become less reliant on GPRO we will stay down in the high $30's/low $40's while we all feast on wish sandwiches.
Then we are royally screwed. Here is what is expected: Analysts are estimating earnings of 27 cents per share on revenue of $53.18 million for the latest quarter, compared with earnings of 71 cents per share on revenue of $71.01 million for the fiscal 2016 first quarter.
If AMBA does not blow that out or misses then I think it is over for a while. If they do beat and then project great things going forward then they may be forgiven and the stock may start to rebuild. This is not the opinion of a professional but from someone who has held AMBA for quite a while.
