Looks like this flirtation into the 4s is going to become serious commitment. Though many longs have made 100% already - this is still a good time to get into the stock. As a rule - we avoid chasing, but buying now is not chasing. This stock does need to be bought before the first report of successful improvement of paralysis occurs.  It is prudent to get in before news that shoots sp into the 20s. Anyone buying now is still early to the nviv show. 47mil share float. Almost no institutional investment yet - just 2.5% of shares held by big guys. Insiders with large holdings - 39.47%. When this hits nasdaq or first positive trial update - big guys will be fighting for shares and little guys will be holding tight. Buy before the low float war begins....
