Initially, the thing fueling this was the possibility that the post Chapt 11 shares might have some value since the company did not cancel them, emerged from Chapt 11 and removed the Q. The Company did a Section 363 sale for all its assets, and sold to HTC all or mostly all its assets for around 90 million. Then back in June, there was some calculations done based on preliminary numbers that showed that this could pan out to have some $$ left for the common share holders. If i recall, between .15 and .45 per share.. That was what this started out as, and at this time is the only thing that might have some merit. Based on facts anyway. BUT the $$ amounts being thrown around though are highly speculative and based on that old calculation from June ( Seeking Alpha article ) Since then there have been more a larger claims made against Ciber, so what if anything might be left for commons is not clear.
The rest of this( reverse merger, Legion buying shares because they know something, ect) is all just speculation. Why are Legion holding and not selling ? IDK but I do know they didn't buy them recently, they bought them back in Feb 2017 before the Chapter 11 proceedings . That is clearly shown in the filings if people would care to go back that far and actually look. Not saying there is not money to be made here, and who knows what might happen, just be aware, in the end, there may be nothing to back up what you paid for your shares. IMHO.
