RE: Are Pref A the Key "why is NB buying all the shares, they could just as well as bought as anonymous and hid the fact as I can`t see anyone else buying 90% of each day trade"
Who do you think 'Anonymous' is on the sell side? Yes, 'those two' do account for 90% of the trades. Why do you think they call them Market Makers? Where do you think the market would be if those 'two' did not create and account for 90% of the market volume?
