The Globe and Mail attempts to identify Canadian companies showing strong economic performance as well as revenue growth, trading at least 10 per cent below their 52-week high in its Tuesday, July 19, edition. The Globe's Jean-Didier LaPointe writes in the Number Cruncher column that he screened all Canadian stocks covered by StockPointer (1,600) by looking at the following metrics: An upside potential between the stock price and its 52-week high of 10 per cent or greater; an economic performance index, or EPI (return on capital divided by cost of capital) above 1. An EPI ratio of 1 or more indicates a company's capacity to create wealth for its shareholders (a higher EPI displays a greater rate of wealth creation); a return on capital of 10 per cent or greater; a positive sales growth over the past 12 months; and an annualized dividend growth rate of 5 per cent or higher over one, two, three and four years. Canadian companies showing strong economic performance are Alimentation Couche-Tard, Magna International, Constellation Software, Gildan Activewear, CI Financial, Stella-Jones, Stantec, Enghouse Systems and Exco Technologies.
