Remember we traded 13.2M shares 2 days before the June 24 release. That day everyone was scratching their heads...2 days later we knew why the big volume. It came after some very low volume trading days. There could be news coming but just not pr'd yet in a few days.
However I might add KRY on Amex did more than double average volume. KRY.TO traded below their average volume. Was this just a combination of a large position entering the market on the Amex side and traders jumping in on the volume? Or was this some info leaked on the Amex side. It is a bit strange KRY.TO didn't follow with the large volume.
