Agree with you on this on Mac B.
The loss of 17m and further downgrades reeks of management incompetence. And with Roche now admitting the "informal" discussions were only in relation to individual assets, not for the entire company, I'd say we'll see sub 2.
Guess we'll have to wait and see if the 6% of the stock traded in the last couple of days shows up as a significant holder OR just day traders.
