Stocks edged lower in early trading on Tuesday, with investors awaiting Federal Reserve Chair Jerome Powell’s speech later in the day, with a mixed session so far for the Standard & Poor’s 500 sectors.

Powell is set to speak at 1pm ET in New York on the economic outlook and monetary policy review, according to the Fed’s website. It comes during a week where Wall Street is also anticipating the Group of 20 event later in Japan, with President Trump poised to hold meetings with world leaders including China’s Xi Jinping.

“Global equity markets moved little yesterday and look essentially directionless in the lead-up to the G20 meeting,” said Masanari Takada with Nomura Instinet. “Most major categories of trader appear to be waiting to see what happens next.”
