Thanks for that - I was thinking in terms of the 17-20% that's currently owned by the big guys. Posts here have suggested that it's a good sign that they seem to continue to be invested, and that we ought to worry if they sold up. I was thinking that maybe the amounts involved are peanuts to them, and that they may have already written off their holdings, at least notionally, and therefore have already made the decision to hold regardless of what happens. That would, in turn, affect how much weight anyone here ought to put in them not selling up.
