Probably about to get bought upI was invested in KDX and just reinvested my profit into this. While most would see today as a big disapointment, I can tell you that this is exactly how Klondex was trading before they got acquired,
"They" probably did this (in KDX case) to convince management and investors about the "70% premium" over the stock value they were offering for the company.
I might be wrong, of course, but right now I would assume that all the majors are about to want to snatch up the juniors while they are still cheap. Gold might truly reach 1400$ before year end at this pace.
