Forgive me, BOW2U, but I'm not sure I understand your post and just want to be clear about what you're asking. You're asking to bet about something we have no way of ever definitively knowing the answer to? Or do you have access to a more detailed short report?
You could absolutely be correct. I don't have access to a detailed short report to know one way or the other. If you know definitively a large short position was taken out before the drill results were released, I would agree that's fishy. My experience has been that there are traders waiting on the newswires to pounce on good and bad results alike, so it wouldn't surprise me to see traders take a short position of 300k the first day of trading after the results were released. That's normal market activity. Perhaps that's what drove the opening shareprice so low that day. We also don't know if those shorts ended up as losing positions, which they likely did considering the quick rebound.
Sorry, BOW2U, but I guess I'm left wondering what there is to bet on? I can't prove on what days the short postions were taken out. If you can prove the dates, go for it, and I'll bow to you.
