Markets head into the week ahead, battered by trade war fears, and the selling pressure could continue if there are no signs of a breakthrough.
Two events on the trade front could impact markets. There is speculation that progress will be announced on renegotiations of the North American Free Trade Agreement, when President Donald Trump, Mexican President Enrique Pena Nieto and Canada Prime Minister Justin Trudeau meet at the Summit of the Americas in Peru at the end of the week.
The other event is a much-anticipated speech by Chinese President Xi Jinping on Tuesday, which traders are watching for any reference to the trade dispute with the U.S.
Relations between the U.S. and China appeared to deteriorate, after Trump threatened more tariffs Thursday night, on an additional $100 billion in Chinese goods. A Chinese Ministry of Commerce official Friday responded with a promise to fight back with a "major response."
