Avoid these 3 auto stocks as Trump threatens 50% Canada tariffs

Magna International (MGA) fell 7.19% after Trump threatened 50% tariffs on Canadian vehicles and parts. Ford (F), Stellantis (STLA), and GM also declined. Magna, with high Canadian exposure, thin margins, and a beta of 1.86, is most vulnerable. Ford has negative earnings, high debt, and significant Canadian operations. GM has high leverage but less direct exposure. Stellantis, already down 54% YTD, has lower direct exposure but faces broader macro risks.
