Pieris is in an upward channel and looking bullish. Analyst ratings on the stocks aren't great, but Zacks has given it a HUGE Earnings Surprise Prediction (13.25%!), which should help the stock continue its run until the next report date in early August. Be aware, however, that it is approaching some stiff resistance above $4.60. It should rise Monday, but then it may go horizontal for a while until the channel pushes it upward.
