The Globe and Mail reports in its Saturday edition that exchange-traded funds provide an attractive combination of diversification and low cost that is especially appealing for people who do no have the time or interest to manage a portfolio of individual stocks. The Globe's John Heinzl writes that another benefit of dividend ETFs is that, if a particular dividend-paying company falters -- think Algonquin Power & Utilities or Corus Entertainment, for example -- your exposure will be limited. What is more, you will not have to fret over whether to sell or hold the stock in question, because the decision is out of your hands. With individual stocks, on the other hand, when something goes wrong the financial losses are often compounded by emotional upset. Mr. Heinzl says that if you would rather not put yourself through the pain of seeing one of your stocks implode, then ETFs are an excellent alternative.
