The insiders are 4 managers of the company. Their stock came from buying options matured, the transactions were set before to take place when/IF FDA approeval. You , as an investor should look at future and if you are a good investor you should look at down side and up side. Before approval it was a risky game. Now the pesimists are talking about a value of 5-5.95 while calculating the revenue from one drug that was approved. The up side is : at least 6 to 7 new products in the pipeline. ( for some the pipeline may be long). A potential buyer , no one will sell the company for 7$ price as it is now, and i can assure you that even that i am not a board member , even not for 9$. I would say one does not need to be a fox to be on the long here.
>> Their stock came from buying options matured <<
That was my initial impression, but when options mature it means that the holder of the option has the ability to BUY the stock (exercise the option) at a greatly discounted price within a specific timeframe.... which these guys obviously correctly did.
It does not mean that one has to sell the stock once the option is exercised.... which these guys then went ahead and did, foolishly and inconsiderately to all other shareholders all at once.
