NEW YORK — A jump in U.S. consumer confidence sent stocks modestly higher Tuesday. Investors were also encouraged by new efforts from European leaders to find more aggressive cures for the region’s debt crisis. The Dow Jones industrial average ended with a gain of 32 points, following a 291-point surge Monday.

Technology stocks were weak. Corning Inc., which makes glass for flat-screen TVs, slumped 10.8 percent, the most in the S&P 500, after saying a major South Korean customer would no longer do business with it.
