CETX they need to get a new auditor, I will give you that. I would just be careful, my feeling about this stock is the negativity is following the price, not the other way around. In my opinion the better explanation for the oddities you mentioned is #1 goofy management and #2 empire-building at high cost.
Just like when FONR was in the $9s and everyone was complaining about bad capital structure, no growth, and lower scanner sales. And now its in the $16s with a bad capital structure, no growth and low scanner sales. Negativity follows the price.
I no longer own shares in either
