Graphs showing buyers and sellersAs an FYI, here are a couple of graphs that show ACB shares held by trading institutions relative to November 2nd when I started tracking trades.
First shown are the share accumulations for institutions that are net long.
Note that Canadian banks are net longs as are a few big US banks.
Those institutions that are driving share price down are Goldman Sachs, Instinet and Anonymous traders. By far the largest influencer is Goldman Sachs. It was Goldman Sachs that drove ACB price down by selling 4 million shares upon ACBs earnings release. Instinet is a private dealer network that only subscribed dealers get to see. Anonymous appears to be opportunistic day traders.
