Stock performance sucks. Management can't get it together. Earnings disappoint. and so we're at about four year low. If you have a better place to put your money, its probably a good idea to do that. BUt beeing the emotional hanger on that I am, I chose to average down and here are my reasons:
This company has a history of making succesful changes in the past 30 years. The changeover was not unexpected and I think INVX has done a good job transitioning. Insiders are buyers over the past few months. Management has made changes aimed at getting the company on track.

Whatever your opinion may be, I beleive it will take some time (2 qtrs) to see if they have pulled it off or not.
