I have heard a while back that of all canadian banks, CIBC is the most likely to be in trouble and therefore am not surprised if they are using some of the best tactics used down south. I do not think bankruptcy is the issue with them but profitability must be the cause. Too much exposure to the derivative and related trade.
Could it be that the financial institutions in trouble are the ones shorting (and what ever else) the markets and regulations be damned because when bankruptcy stares in the face there are few options.
This could be part of the answer to some of the woes experienced by many of our stocks price wise.
