The Financial Post reports in its Friday edition that Canada's telco stocks have fallen to multiyear lows as competitive wireless strategies failed to impress investors, but some analysts say the rout is presenting a good buying opportunity. A Bloomberg dispatch to the Post says that the S&P/TSX composite's communications index has been the worst group performer in the broader index this year, posting a loss of nearly 16 per cent since early January. Rogers Communications and Telus are trading near their 2016 levels; BCE is trading at its lowest point since 2013. One reason for the slump: The companies' wireless strategies "aren't doing right by investors" as they try to win on price after Rogers closed its deal with Shaw and Quebecor acquired Freedom Mobile, Adam Shine, financial markets analyst at National Bank of Canada, said in a recent note. This "promotional intensity" is weighing on growth and share prices, he added. The slump, however, presents an investment opportunity, said RBC analyst Drew McReynolds. "Given the recent heavy underperformance of the sector, we believe the stocks are poised for a bounce," he said. Canaccord Genuity analyst Aravinda Galappatthige is also betting on a recovery.
