Before buying or shorting this stock there are 2 things to know:
First, the biggest factor in the future of this stock price is the documented fact that revenue is growing at 68% year over year. This is huge growth that can not be ignored as investors that buy on future growth. Second, insiders for YELP are new to the game of being rich. YELP is a newly listed on the exchange stock and virtually made millionaires over night. Now that lockup has expired, of course these new folks want their money. Thats the reason they are selling. If insiders are also investors, anyone will tell you all eggs in a single basket is a terrible crime that any financial adviser would not recommend. This justifies the selling. The key here is what happens when the selling by insiders are done........ TO THE MOON.
