U.S. stocks slide as investors await details on next Fed hike

Stocks are falling on Wall Street, putting the S&P 500 index on track to break a four-week winning streak. 

After a mixed bag of corporate earnings, more solid jobs data and a steady retail sales report, investors may already be looking ahead to the Federal Reserve's annual Jackson Hole conference in Wyoming next week for indications of when and how much the U.S. central bank might raise its main borrowing rate.

As of noon Eastern time, the S&P 500 was down 54 points, or 1.3%, to 4,237, while the Dow Jones Industrial Average fell 0.8%. The Nasdaq dropped 2%, as technology stocks had some of the biggest losses.
