The Globe and Mail reports in its Saturday, July 25, edition that Canadian companies are once again facing challenges from President Donald Trump's unpredictable trade policies, dealing with tariffs and disrupted supply chains. The Globe's David Berman writes that Magna International, however, has seen its share price more than double from a low 15 months ago, leaving investors puzzled. How high can this stock go? Mr. Trump's second term is marked by belligerence toward allies and trading partners, showing no signs of change. Last week, he announced 50-per-cent tariffs against hundreds of Canadian exports valued at about $20-billion (U.S.) in total, a year after imposing tariffs on steel, aluminum and autos. Magna, however, is cruising through these uncertain times, underscoring its delightfully neutral place among trading nations, automakers, vehicle models and powertrains. Magna has beaten the share performance of Ford and GM alone by 19 percentage points, on average, over the past 12 months. As well, Magna has outperformed Nvidia. If Magna s rally is proving anything, it's that it is a bigger force than Mr. Trump's trade policies -- and a stock to own when he's trying to make a deal with scare tactics.
