I would be more disappointed if there aren't any purchased by the April reporting deadline. Not buying would indicate to me that the company is comfortable at the current valuation.

But in defense of the company with rising interest rates it makes a lot of sense to hord the cash rather than buying back shares. With cash on hand it makes the company attractive to investors. 

With increased payroll cash can be burned through pretty fast. Also with market conditions there may be another oppertunity to buy into another company that will fit nicely into PYR.

Until the 4 torches are factory tested, and then the one followed by the four are installed and put into opperation and tested on site the news of selling more is going to take another six months at least. So the stock price will be flat at the current levels. The smaller contract announcements just don't seem to move the neddle. I as well as many other shareholders thought we would be at the very least up around $6, but we aren't for a number of reasons. Hang in there.
