Dec 1, 2020This week, our Your Stock Our Take segment is on BlackBerry Limited (BB: TSX), the former undisputed heavyweight of the smartphone market, which is continuing its transformation into a provider of business security and information integration services. The stock surged over 50% at one point today on a deal with Amazon’s AWS. Is it hype or justifiable? Our Dog of the Week is Sona Nanotech Inc. (SONA:CSE), a Life Sciences company with the goal of developing and producing its own lateral flow rapid COVID-19 antigen tests. The stock, a market darling earlier in the year, is down over 92% from its highs, and 62% this week alone. We reviewed it earlier in the year in the $2.00-$2.50 range and with zero sales and only a small chance of actually selling its test kits in a tight time frame, we saw no serious investment merit long-term in the stock. With Sona cut in half, we take a look at the business once again. Our Star of the Week is Sierra Wireless (SW:TSX), an embattled Canadian-based technology company which has rebranded itself as an IoT (or Internet of Things) service provider. The stock, which has had a rough ride over the past 3-years after peaking in the summer of 2017 in the $40 range, was up 32% this week. We investigate what is driving the uptick.
