U.S. stocks opened modestly higher Wednesday as investors weighed the potential risk that Italy's latest political drama posed to global markets. The Dow Jones Industrial Average rose, the the S&P 500 advanced 0.6% at 2,705, and the Nasdaq Composite Index climbed 0.5% at 7,430. Italy's stocks and bonds, as well as the euro were all attempting to recover.
