I dont think the P/E is an issue. My broker data says the sector P/E ratio is 37. Many growth tech stocks surge ahead on huge multiples, TNE, JIN , APT and many more have been well in excess of 100, and you can look at XRO to really blow your mind at 1000+.
I believe the exits we are seeing is people unhappy with the failure of the price to rise in response to the recent report.. Also the stock is being manipulated all the time by the pros, which tells me they want in.
