I bought RVX for the first time when I was sitting in a presentation by Don et al at the 2015 Biotech Showcase. There were others in the audience that did the same thing right there or soon after...as the price took off quickly, moving from 45 cents ($.39 US) to over $3 ($2.49 US).
When Don came to the podium (after the science presentation) he said flatly that he thought the stock was an incredible bargain.
My point is that similar conditions exist today and it is easy to see how some of the audience could have reacted immediately.
