NEW YORK (Reuters) - Fear returned to Wall Street on Wednesday, sending the S&P 500 to another 4 percent decline, triggered by worries that Europe's debt crisis could engulf French banks and spill onto the U.S. financial sector.
Trading was once again marked by sharp moves on heavy volume. For a fifth straight day, the Dow industrials fluctuated （波动） in a range of more than 400 points.
"What you're seeing is a very short-term, direction-oriented market," said Eric Kuby, chief investment officer of North Star Investment Management Corp in Chicago.
Worries about the strength of French lenders （债权人）, including Societe Generale, triggered a selloff （(打折扣)销完， 变现） in European and U.S. banks. Rumors about SocGen's financial health, which the bank denied, sent its shares tumbling （暴跌） 14.7 percent.
An index of European banks dropped 6.7 percent and the KBW index of U.S. bank stocks slid 4.9 percent as fear grew of a possible contagion （传染，蔓延）of any French crisis. Bank of America Corp lost 10.9 percent to $6.77 and Goldman Sachs slid more than 10 percent to $110.34.
The Dow Jones industrial average lost 519.83 points, or 4.62 percent, to 10,719.94. The S&P 500 fell 51.77 points, or 4.42 percent, to 1,120.76. The Nasdaq Composite dropped 101.47 points, or 4.09 percent, to 2,381.05.
Wednesday's drop came a day after stocks rallied on the Federal Reserve's pledge to keep interest rates near zero for at least two more years.
Even after Tuesday's snap-back rally, the S&P 500 is down almost 18 percent from its 2011 closing high set April 29.
The losses came against the backdrop of recent weak U.S. economic data, the United States losing its triple-A credit rating from Standard & Poor's （标准普尔） and the inability of lawmakers to address worries that another recession may be on the way.
About 15.1 billion shares traded on the New York Stock Exchange, NYSE （纽约证交所） Amex （美国股票交易所） and Nasdaq, almost double the year's estimated daily average of 7.8 billion.
Volume once again spiked （抑制,挫败） in the last hour of trading, and the market closed near its session lows. Of late, overleveraged investors with losses on their books have been forced to sell shares near the end of the day.
"Between 3 and 3:20 (p.m.) you have people getting margin calls, and on days like today there's some nervousness about what those calls will look like," said Andrew Frankel, co-president of Stuart Frankel & Co in New York, referring to the volatility （变动不止） of the final hour of trading.
Slides in the value of stocks may increase the cash needed in margin accounts, which can spark （激励） further selling.
Dow component Walt Disney Co dropped 9.1 percent to $31.54 a day after the entertainment company's quarterly results failed to reassure investors that it could do well in a weak U.S. economy.
After the closing bell, Cisco Systems Inc's shares jumped nearly 12 percent after its quarterly results edged past Wall Street's scaled-back expectations.
Declining stocks outnumbered advancing ones during the regular session on the NYSE by a ratio of more than 8 to 3, while on the Nasdaq, almost five stocks fell for every one that rose.
