My wife and I finally decided to open up a TFSA trading account last week. I had picked out the companies and number of units we were going to buy and set up the account. But in the time that it took to set up the account, everything I had my eye on has increased an average of 20%. What is driving this? There have been some positive news releases, but I am not sure if it warrants this type of growth. Is this just some pent up urge to buy that was released because of some good news, or is it more than that.
