U.S. stocks tumbled to new lows for the year on Thursday after a disappointing earnings and outlook from technology bellwether Hewlett-Packard Co. and record oil prices jolted confidence. Mixed economic data muddied the picture as retail sales data showed shoppers still trying to cope with higher energy prices and stagnant wage growth. The combination of bad news sent the Nasdaq to its lowest close since Aug. 18, 2003, while the Standard & Poor's 500 closed at its lowest level since Dec. 10, 2003. The Dow Jones Industrial Average also hit a new low for the year, notching its lowest close since Nov. 28, 2003. "We are seeing the cumulative effect of Hewlett-Packard, higher oil, higher rates, not such a great third-quarter outlook for companies and then the general economic numbers," said Brian Williamson, vice president of equity trading at The Boston Co. Asset Management. The Dow Jones industrial average ended down 123.73 points, or 1.24 percent, at 9,814.59. The Standard & Poor's 500 Index fell 12.56 points, or 1.17 percent, at 1,063.23. The technology-laced Nasdaq Composite Index lost 29.93 points, or 1.68 percent, at 1,752.49. --MORE 0001 Local Time 2101 GMT
