Stocks rallied today, led by advances in the tech sector, the Wall Street Journal reports. Intel and Hewlett-Packard jumped after Best Buy posted a 12% sales increase. Investors were also reassured by strong demand for 7-year Treasury debt, after weak results in yesterday’s 5-year auction. The Dow closed up 174.75 at 7,924.56. The Nasdaq rose 58.05 to close at 1,587.00, and the S&P 500 gained 18.98, settling at 832.86.
