The borrowing does not show up on volume, but the subsequent selling of those shares does.
As for the conference presentation, no new material info can be announced because it would not be equally accessible to everyone at the same time. Any new material developments will come via a PR, not a presentation. That's not to say the presentation can't influence buying, after all that's the whole purpose of these.
BTW it's been my experience that there is almost inevitably a post-conference (or conference call) price slump, as the shorts seem to know how to play these pretty well. Retail investors seem to always anticipate new material developments will be announced, which inevitably aren't. The subsequent disappointment inevitably sets up an opportunity for the shorts to run the price down.
I look at these post-conference dips as buying opportunities :)
Seems like your new around here. You couldn't get this to move to 2 without a buy out rumor. This is stuck in mud for six to nine months. Everyone has been bummed out by management and the outcome of testing. Has zero, none, absolute no shot on any fundamentals to reach 2 dollars again this year. This has been going on for ten years, if you like your sanity then move along, this is the end of the world stock right now. lol
