RE:BMOI don't think there is anything to worry about. BMO tracks with the other canadian big banks very closely, if not slightly more volatile. One thing I have noticed is that stocks are running up for dividend day and then crashing. (i.e Check out KEY.TO that pays .16 cents every month. Wait a few days after ex-divi and buy, and then sell a day or 2 before the next ex-divi. Last time it dropped about $2. Dividends for suckers.) BMO was $74 the day before ex-divi, and then started the drop the next day.
Good luck
