Company has close to a 50% short float. No come on Stock Twit guys, who do you think those 50% investors are that is shorting this stock on all you longs. It is the large hedge funds and mutual funds and larger investors that realize their original investment going long is not working out. So to reduce loss exposure, they are shorting this stock on you guys, reducing stock price into the 40's , then buying.... stock price raises to .50 or so, then they sell their long position for a gains - and then they short at .50 and drop press as a result into the 40's.
This is not market manipulation, it is called day trading via computer algo systems (which is legal).
