NEW YORK (Reuters) - Stocks extended losses on Wednesday, briefly sending the Dow and the S&P 500 down more than 4 percent, on mounting concern of a recession, which cut investors' appetite for riskier assets like stocks.
Among companies reporting disappointing quarterly results was plane maker Boeing Co, whose shares tumbled 7 percent to $43.15.
The Dow Jones industrial average tumbled 352.37 points, or 3.90 percent, to 8,681.29. The Standard & Poor's 500 Index dropped 36.67 points, or 3.84 percent, to 918.38. The Nasdaq Composite Index fell 40.73 points, or 2.40 percent, to 1,655.95.
