Query: I'm talking about a globally diversified portfolio. If you focus on a  small market such as Canada (about 4% of global market cap), and further focus on just a part of that market, you will have a wider dispersion of returns. That means sometimes you'll do better (get lucky) and sometimes worse (get unlucky), but on average you'll do worse than a globally diversified portfolio.
