The S&P 500 index was down 11.13 points at 2,804.49 and the Nasdaq composite index was down 29.14 points at 7,825.30.Trade tension could have also played a role in pushing down the Canadian dollar, which averaged 75.44 cents US for a dip of 0.29 of a US cent Thursday.“All these trade talks, trade wars, the idea that the U.S. President could put tariffs on automobile parts and automobiles in general.
