insiders keep on selling. They know its never going over 4. Form 4 insider sales.
If you are so confident that the stock is going to 30, why would you sell at 4? If I were on the board and I knew that the stock was going to 10 or up, there's no way in hell I'd sell even a share of stock now. How about this don't exercise your options at 4 if you think the stock is going to 10. Your shares will be worth much more at 10 then they would be at 4.
