What caused the run yesterday? Leaving aside the usual chatter about T/O my broker thinks that it was to do with the Opes Prime matter, it being important to have a high sp on that particular day to fix the level for assessing damages. I simply don't know if this is true or not

I hope it was because of leaked info which will be released to the market very soon.
