RE:CIBCIf you have a direct investment account with a bank like CIBC, RBC, etc and sell or buy shares, your name doesn't appear as the seller. It is the name of the institution handling the sale or the purchase that appears.
Now the other day there could be there could have been one investor who sold a large number of shares through CIBC or there just could have been a number of investors who sold through CIBC that day.
