U.S. Stocks Open Slightly Higher, On Track For Fourth Straight Daily Rise

U.S. stocks opened with a modest gain on Tuesday, suggesting the market's recent upward bias remained intact as investors looked past a suspected terrorist attack in Manchester, England. The Dow Jones Industrial Average rose 35 points, or 0.2%, to 20,930. The S&P 500 ticked up by 3 points to 2,398, a rise of 0.1%. The Nasdaq Composite Index rose 17 points, or 0.2%, to 6,151. All three indexes are on track for their fourth straight daily advance, having shrugged off a sharp decline last week, which came on rising political uncertainty. At current levels, major indexes are about 1% below their all-time highs, hit earlier this year. Among the most actively traded stocks of the day, Agilent Technologies Inc. rose 6.7% a day after it raised its earnings and revenue outlook, while Take-Two Interactive Software Inc. surged 8.3% after it posted results that blew past expectations.
