Wall Street's main indexes were little changed following strong weeks as investors geared up for a big week of corporate earnings and awaited commentary on the impact of trade disputes between the United States and its partners.
"Trade and trade rhetoric will be a focus of the market," said Mona Mahajan, U.S. investment strategist at Allianz Global Investors in New York.
"As we get into earnings season in particular we are going to be watching for management teams to discuss their outlooks not only in the numbers but more generally anecdotally how trade could impact their businesses.”

The dollar index fell 0.2 percent, with the euro up 0.17 percent to $1.1705.
