Specialists work on the floor of the New York Stock Exchange in New York, Thursday, July 24, 2008. Wall Street abruptly ended an earnings-driven rally and closed sharply lower Thursday after a steeper-than-expected decline in existing home sales and worries about the financial sector chilled the market's recent optimism. The major indexes fell about 2 percent, including the Dow Jones industrial average, which lost more than 275 points.
