CNXC -1.68 to 23.17, if a 10% holder files to sell their entire 6M share position with the stock at all time lows, then I can only presume that they've done extensive due dilligence and have concluded that the company is in an unrecoverable downward spiral. If the company were in a strong financial position, they could easily snap up those shares on the cheap, but obviously that's not the case.
I'm continuing to hold my small position to see how this plays out, but expect that it will be a tax loss sale for me later this year.
