The Globe and Mail reports in its Saturday edition that Bombardier has enjoyed a remarkable turnaround over the past five years. The Globe's David Berman writes that demand for its aircraft, including the Global 8000, is strong; aftermarket revenue for servicing existing planes is rising at a double-digit pace; and the company is benefiting from growth in one of today's hottest sectors, defence. The question now is, Will Donald Trump derail the stock with his threats to ban the company from selling in the United States? Given the initial slump in the share price, some investors took the threat seriously. And to be clear, analysts aren't laughing off the threat as an impossibility. "It is too early to assess the fundamental risk as Bombardier has thus far navigated the geopolitical uncertainties without any major demand impact," Konark Gupta, an analyst at Bank of Nova Scotia, said in a note. Mr. Berman points out that this is also the TACO President. His threats often amount to little more than hot air. Arguably, the biggest risk in buying Bombardier shares today has nothing to do with the trade war. Rather, the shares are still pricey after a four-year rally. But if Mr. Trump delivers a bargain, take it.
