The Globe and Mail reports in its Monday, June 13, edition that looking at the Street's average one-year price targets for stocks in the S&P/TSX composite index, numerous securities are either approaching or are already above targets, implying further upside may be limited. The Globe's Jennifer Dowty writes that it may be prudent to consider adding a defensive security to your portfolio. Ms. Dowty says one security she believes is worth considering is Fortis ($41.86). Fortis serves customers across Canada, as well as in the United States and the Caribbean. As of Dec. 31, 96 per cent of its total assets are low-risk regulated utilities. Fortis mitigates regulatory risk and economic exposure by ensuring that no single jurisdiction represents more than 33 per cent of the company's total assets or operating earnings. Fortis pays shareholders a quarterly dividend of 37.5 cents per share, or $1.50 per year, equating to an annualized yield of about 3.6 per cent. The average one-year price target is $45.28, which is based on seven "buy" recommendations, two "holds" and no "sell" recommendations, implying the stock price may appreciate nearly 9 per cent over the next year.
