Unfortunately we do not have tick charts any longer than 10 days, so we are looking at an incomplete picture. Today Draghi, Bernanky and Pan Gongshen came out with a joint communiqué in which they expressed their unreserved conviction that Niko should close the gap at $21.21 and they promised to do whatever was needed to get it there. Just kidding.
This looks like the start of a third wave (starting from around $13), you are already up 30% or so, why not enjoy the ride. It may go a lot higher!
