1) The industry is very highly regulated. I trust the major firm's research as being well intended. And when nine out of ten agree, it lends even greater credibility. However, I simply use their data to come to my own conclusions using my decades-long proven formula.
2) Wrong. ENB's average trading volume in Canada alone is 1.81 million shares a day while AQN's is 1.04 million. And ENB's share price is 5 times AQN's. I actually own almost an identical numbr of shares in each company and am below that 10% of average daily volume but closer to 10% on AQN since it does trade less. Won't go much higher except for my DRIP.
3. Because if / when I do need to exit, I want to ensure that I'll be able to. I did sell a couple of positions a few weeks back and it took me two days to exit. But it was a good move and the CRA will be pleased.
Correction: I own more shares of ENB than AQN because (they are about equal in non reg accts) I own ENB in my RRSP and in my TFSA.
