You may be right. All of the recent increase in price is with low volumn. I guess this could indicate a group with inside information buying the stock. WIth it being Summer the low volumn could be an indication that the institution ore in their summer inactive period and all the buying is from individual investors. If that is the case I am surprised there are so many aware of the company. It bodes well for what will happen come September when the Institutions will once again awaken from their Summer slumber and start looking a new for places to put their funds.
I think that the low volume is simply patient accumulation by institutions and other "smart" money in advance of multiple future income streams in 2014 and beyond. It will be interesting to see the updated institutional holding numbers in mid-August (they are required to disclose to the SEC 45 days after the close of each quarter).
