Stocks fall as Trump turns his attention to trade war

U.S. stocks dropped and the dollar rallied the most in two weeks as the trade dispute with China showed no signs of easing. Commodities sank.

President Donald Trump signaled Thursday he’d press on with the trade war.

“One of the bigger risks that we keep watching is the trade talks with China. The fact that there’s still discussions going on is good and the fact that both sides are still willing to negotiate is good, but I don’t think that there’s going to be anything monumental that’s going to happen before the midterm elections,” Liz Young, senior investment strategist at BNY Mellon Investment Management, said in an interview at Bloomberg’s New York headquarters. “China is probably going to wait and kick the can down the road until we get there and then see what happens.”
