Indeed.
Does this not go some way to shooting down the "it's not significant....it's only 0.0000004% of the overall share allocation...." argument that a lot of the cynics come back with when someone highlights a batch of round 5 figure sums being traded from time to time?
In other words, if it's difficult to get one's hands on 10,000 shares then when one sees a series of such trades, more or less at MARKET RATES, then 'something' relatively significant must have happened behind the scenes to make it happen?
