Hey Sweeney and others ...HOW MANY TIMES must I write that there are no Market Makers in Canadian stock markets. Perhaps it is a moot point but in the U.S. they are the system itself .. and the Market Makers must declare themselves and be accepted. In Canada we use the Auction System. However there is no doubt that there are game players who are powerful enough to manipulate share prices. But they do not trade out of the same brokerage houses all the time because they are clandestine. But it takes big money. Maybe we are witnessing that here.
