RE: insider buying I don;t think production updates have anything to do with insider purchaces or sales. What matters are the financials, as regardless of how much a company improves in sales or not the bottom line i swhat rules the day and taht is done every quarter.
So no insider buying right now would seem to indicate that the strike price for those insiders is still higher than the present share price. Better they hang on wait for the SP to rise significantly to either get new shares or sell the ones they bought earlier at lower prices.
