The increased trading volume during January and February has clearly not come from official short covering. So logically it would have come from new investors. Probably a part is indeed fresh money, but I strongly believe that the large pools of hidden and illegal naked shorts are the main source of buyers. One day in the future we may see evidence of the scale of the virtual money attack that this company and its shareholder have had to undergo during the period 2010-2013. It wouldn't surprise me that the amount of shares nakedly sold short will turn out to be much larger than the number of shares in circulation. For the gamers active in the forex markets this is an easy thing to do, when permitted by the regulators.
