what to do with this stock?

I am in a bit of a predicament with this stock. I have owned it for years and was always a believer as it used to perform so strongly. The latest results were disappointing but I do have hope that things will improve this year with some of the various new developments underway (as I have posted in other threads). However the share price is being hit hard. It appears to have broken through support level around $1.40 and is still heading downwards. It hasn't had an up day for a while. The question is whether to sell before it heads lower and say goodbye to this stock or buy more at these levels as it potentially represents good value. What is everyone else doing? Do you think this stock will be re-rated over the coming year?
