I am very far from an expert when it comes to trading but for a trader selling halv one's shares now looks wise to me based on past experience. To me the probability of a certain retreat of the pps from the current Level seems at least as high as the opposite. I am no trader and I would buy rather than sell shares right now if I had had any cash available since I expect the pps to be a lot higher in a year and there could always come some surprising positive News.
