This could be a bull flag. Earnings are coming up next week. Perhaps insiders know it's going to be an earnings beat and are buying it up. $22.40 target if this turns out to be correct.
Look at that big fat volume bar off the back of the successful trial news. The company's stock price has been growing steadily up some 164% over the last 12 months, and this news could help propel it back up to previous highs so there might be a bit in it. Worth a watch.
