The Globe and Mail attempts to identify Canadian energy companies with higher revenue exposure to the United States than Canada in its Thursday, July 11, edition. The Globe's guest columnist Christine Elegado writes in the Number Cruncher column that if the Bank of Canada continues to lower rates while the U.S. Federal Reserve holds steady, it could lead to a devaluation of the Canadian dollar relative to the U.S. dollar. Consequently, Canadian companies with a higher percentage of revenue from the United States could gain a competitive edge against their peers. Moreover, companies selling energy products -- Canada's top export to the U.S. -- could benefit greatly if demand increases because of a lower Canadian dollar. As such, Ms. Elegado searched for Canadian energy companies that could stand to gain from a weaker Canadian dollar. Her picks had to trade on a Canadian exchange and have a market capitalization greater than $1-billion. Of the six companies that passed Ms. Elegado's screen, Cenovus Energy made it to the top of her list. Cenovus has nearly equal revenue exposure to the U.S. and Canada at 49.7 and 48.1 per cent. Cenovus also boasts a low price-to-earnings ratio of 10.3.
