Well someone has been trading in the US and Canada since the June 7 announcement.
For example take June 7 and the following 7 days on both exchanges combined the volume totals were approx 99M for those 8 days.
Then if you add up to today just all the days trading above 1M on both exchanges you get approx 21.8M.....all of these days add up to 120M traded.
Now the question is who is it and what did they do buy or sell. We know West Face Capital picked up a cool 19M out of that due to their 13G filing.
As for June or 2nd qtr reports for institutional investors and funds start rolling out in August so we will probably know a little more on what transpired by the time the shareholder vote rolls around.
