They have appointed advisors. They have announced both visual results and actual results. They are playing it a bit cool - why rush marketing messages when you are going to have genuine upgraded results shortly - which will make the company more valuable.
Accumulation is the name of the game at present IMO. (No special knowledge, just observation)
IMO (again) Someone who already holds quite a number of shares is playing the bot game - selling to themselves - and triggering other stop outs and weaker holders to let go. I think they are building further position in the process.
I see these moves as quite positive - I watched similar things happen over on the EXT threads.
I think it's good buying at this level - may collect a few more before the real game begins.
