The run started with the discovery of the N-Assay being allowed. It might be that the Saudi FDA update added fuel to it, but I don't think so. Its obvious that whoever bought the majority of shares is not looking to sell at current levels. I think they realize the value of the N-Assay patent and have taken an initial position in anticipation of the N-Assay being finally issued. On the discovery/PR of this event, I believe the share price will take off.
