The Globe and Mail reports in its Friday edition that at a time when the Canadian economy feels like it's under siege, the Toronto Stock Exchange serves as a powerful counternarrative. The Globe's Tim Shufelt writes that over the past two years, the Canadian stock market has gained nearly 55 per cent, after factoring in inflation. That ranks among the very best two-year stock rallies in history, such as the dot-com boom of the 1990s and the rebound from the global financial crisis beginning in 2009. Contrast that with four years of the worst housing bust on record. Among the recent winners is BlackBerry. Most American investors identify BlackBerry in two ways -- first, as a fallen smart-phone giant, and second, as a meme stock. But then came the company's third act as a software player in the automotive sector and in secure communications. "You have no idea how much you still use BlackBerry," the Wall Street Journal said in a recent headline. The company's QNX software is found in 275 million cars on the road today. BlackBerry is now in the process of expanding the use of its mission-critical software to things like robots, medical devices and factory applications. Its shares have nearly quintupled in two years.
