The things that does not add up to support the theory of take over is massive selling at these low prices. The selling is huge. How come some very large shareholders are selling their positions & not waiting for a better price.  Instead of just one buyer UBS there should have been multiple buyers. This massive aggressive selling does not add up somehow. The share price & the constant selling does not indicate instant takeover. Concentration of shares in a few hands & UBS buying indicates otherwise.  There is something very unusual of this stock trading only time will tell what is actually taking place.
