Fundamentals - Bombardier made good progress on their airplane sales, especially with their C-Series planes. However, in a recent article, Financial Times warned about the difficulties the company has with railways products. In addition, the Motley Fool described Bombardier as a "shaky" investment as of now.
Remember that the stock was trading as low as $0.80 in 2016. Such an improvement in this industry is huge. That is why I advise caution if you want to go long.
