Cannot be a pump. From what I can quickly see from the IHUB chart there are million-share trades happening.
Maybe a major fund buying in based on news (we haven't seen) of major orders?
Maybe a takeover? What if Elon Musk is buying this sucker? I mean, why not? He is all about technology, and from everything I have heard POLA remains the state of the art.
Just dreaming a bit -- but you can hardly fault me when there are mega-share buys happening.
