American President, Donald Trump, said on Thursday that the US would introduce a 35% tariff on goods being imported into the US from Canada starting from August 1. The move represents a major escalation of trade conflicts between two of North America’s largest and most closely linked economies.

U.S. President Donald Trump announced on Wednesday a 50% tariff on copper, saying on social media that it would be effective August 1 and that the decision was made after a national security assessment.

President Trump’s proposed 50% tariff on copper imports would likely prove a boon for companies that mine copper in the U.S. So the question for investors is: Which stock should they buy to take advantage?
