The Dow Jones Industrial Average shed 0.2 percent to 24,682.31.

But markets later pulled back during new Fed Chair Jerome Powell’s news conference in which he was asked repeatedly about risks to the economic outlook, including from a possible trade war between the US and China. 
‘Powell’s first press conference was largely uneventful, with the new chair sticking to a script similar to Yellen’s, thus sending a message of continuity despite new management,’ said FTN Financial’s Chris Low. 
‘His answers were safe, offering little guidance on the committee’s thinking beyond what was already revealed.’
