"I think your presumption about all the people that would be privy to this information is wrong."

Maybe maybe not EZ but you have to remember there are bankers involved here as well. Remember the amount of trading that went on June 7? On the TSX UBS sold over 7M shares which I am guessing was short because prior to that day UBS never reported owning 7M shares that I am aware of. These guys were pretty sure of what was to go down in the following days and maybe even months.

BINGO!
