The Vista Partners OPXA endorsement carries weight in my view. Why? I respect this firm for their leadership. As an example, their call on VICR in 2009- after which VICR 4-bagged. I expect OPXA to raise funds leading into the P3 trial, however this shouldn't dissuade the DD-oriented investor. OPXA is staring into a $9b market, and 2011 will be an excellent year for this stock.
