Wall Street seemed to be of two minds on Monday, with stock markets churning up and down as investors take opposing sides of what is essentially an unknowable multitrillion-dollar question: Is Donald Trump’s trade war the commencement of bilateral negotiations or simply the end of the U.S.-led world order?
