Share prices on Wall Street dropped on Thursday in response to data showing a rise in jobless claims and lower than expected growth in factory activity.
The Dow Jones industrial average tumbled 203.00 points, or 2.09%, to end at 9,509.28.
The Standard & Poor's 500 Index slid 27.23 points, or 2.58%, to 1,029.85.
The Nasdaq Composite Index lost 64.94 points, or 3.06%, to 2,057.48.
It was the third straight day of declines, although the S&P 500 is still up more than 50% from its 12-year closing low in March.
