It Should Be VERY Clear By Now....
That we are in some form or fashion, being acquired. An offer, in my guess, is being prepared. The acquirer is buying up as many shares through MS, as possible, and then allowing for "anon" to sell it down on low volume.
As I stated before, we saw this right before Great Bear was acquired. MS was selling down, only to reverse course. Anon was there to sell on the rhino horns, again, on low volume. MS comes in to scoop it all up, and then the offer.
Same damn play book here folks.
