U.S. stocks advanced at the open on Tuesday, putting the S&P 500 on pace for a sixth day of gains, following further upbeat economic data from China and as an alternative solution emerged to a possible Western military strike against Syria. Fears of action against Syria eased after U.S. President Barack Obama said Monday he saw a possible breakthrough in the crisis with Syria after Russia proposed that its ally Damascus hands over its chemical weapons for destruction, which could avert planned U.S. military strikes. Syrian Prime Minister Wael al-Halki said his country supported a Russian proposal for Damascus to give up chemical weapons to avoid a possible U.S. military strike. "Certainly there was the potential for escalation, which was the market's primary concern, and that seemed to be the issue out there," said Tim Ghriskey, chief investment officer of Solaris Group in Bedford Hills, New York. Economic data in China showed stronger-than-expected industrial output and retail sales showed their fastest growth this year, reinforcing signs that the world's second-largest economy was stabilizing after slowing for more than two years. "Another good China-data day and that has certainly been helping," Ghriskey said. However, White House spokesman Jay Carney said Obama would press ahead with his plan to ask Congress to approve the use of military force in Syria, despite Syria's recent acceptance of the Russian proposal. Oil prices pulled back, with U.S. crude off 2.3 percent. Crude prices rose 2.7 percent last week on worries a strike against Syria could spark a wider conflict and heightened supply concerns.
