U.S. stocks are slipping Monday ahead of potential flashpoints looming later in the week that could bring more sharp swings for financial markets. The S&P 500 fell 0.7% in afternoon trading, coming off a winning week in its whipsaw ride that’s been rattling investors for weeks.

Wall Street advanced on Friday, notching weekly gains as investors parsed a spate of earnings and looked for signs of easing tensions in the U.S.-China trade dispute.

Financial markets are likely to remain choppy until investors get more clarity on U.S. trade policy, Wall Street analysts say.
