CIBC was unloading the large blocs (10k to 60k) at the opening and was active seller through out the session and I think they are #1 by volume..

Was CIBC unloading their own holdings or trading on behalf of a private trader?

I trade with RBC Action Direct..I'm pretty certain if I made a 20k trade and you were to look at it, it would show as RBC making the 20k trade not me..So it can be very difficult to pinpoint who'se buying and selling, except for funds like Genuity as you've pointed out.
