Stock futures were weak throughout the early session, leading to a lower start to the week for equities. The early weakness is a reflection of the growing trade war between the U.S. and China. After new tariffs were imposed by the U.S., China has said they will not begin new negotiations and cancelled talks that had been planned for this week. The early economic report from the Chicago Fed, the national activity index, was generally in-line and had little effect on trading. Nearly 30 minutes after the opening bell, the S&P is down 8 points, the Dow is down 96 points and the Nasdaq is down 28 points.
