Warren Buffett has publicly opposed tariffs, describing them as “an act of war,” contrary to social media claims that he supports President Trump’s economic policies. Depending on the outcomes of these tariffs, three stocks are highlighted: if tariffs succeed, Amazon could thrive due to increased consumer spending; if they cause stagflation, Vertex Pharmaceuticals, with its innovative therapies, may perform well; and in a worst-case scenario of a global trade war, Barrick Gold is expected to be a safe haven investment as gold prices typically rise during economic turmoil.
