Here is a piece of advice I think you might want to consider. Do not bet on the share price of AIXG going down. Quite a few "caps" game players have made an "underperform" call on AIXG lately. Before selling this stock short or buying puts or selling calls on it make sure you have a good reason for doing it. Looking at some P/E or the chart is not enough in this case I am afraid. I will try to add some information in the comment section to this post.
