I've noticed this happening far, far too often with regard to stocks that are either part of or related to the MJ industry. Coincidence? I didn't believe it at first; but, I'm starting to wonder? In any case chalk this one up as a learning experience if your new to trading. A good day trader would have dropped it hours ago, another type of trader may or may not have. I believe it will go back up rather quickly just like it always does with ACB, Canopy Growth, or one of the many others; the MJ industry has is own personality to be sure...we will see. Good luck out there!
