I certainly don't know who the large sellers are so obviously my comments are my opinion. However, Aspire has has both the means and motive while Aruda has the means and SEC filings that show sales of millions of shares per year for two years running indicating he has his reasons as well. I've owned this stock for three years and cannot recall any indication that there are other entities with both means and motive to sell enough shares to keep the price at a fraction of what it was in the face of so much progress over the last two years. I'm open minded to any other theories.
