The author of the article appears to have an agenda. He has written similar negative articles on Uni-Pixel (UNXL) om 1/10/2013 and 3/1/2013. The stock price on each of those dates was at $15 and $21 respectively; today it is trading at $34. His profile is: " I am currently an individual investor with focus on event-driven trading and long-short opportunities. I graduated Emory University in 2009 and is also a finance Phd dropout from UCLA Anderson." Seeking Alpha allows this kind of clown to submit articles???
I listened to a portion of the call and thought that the company presented a straightforward account of its results and its prospects. In the portion that I heard, I see no reason for Goldman's downgrade; certainly not at its current pps.
