U.S. stocks dipped on Wednesday asearnings season began with Alcoa forecasting slower demand for aluminum, while a profit warning from Chevron weighed on the energy sector.
But declines were muted as Yum Brands Inc (YUM.N), climbed 8 percent to $70.99 and was the best performer on the S&P 500. The parent company of KFC and other fast-food restaurants raised its full-year outlook after sales in China held up despite slowing Chinese growth.
The overall tone at the start of the earnings season was downbeat, however. The S&P 500 index was on pace for its fourth day of declines over concern the global economic slowdown was hurting profits and causing companies to lower their outlooks. The index was testing the technical support level of 1,440.
Stronger demand from airplane and automobile producers helped Alcoa (AA.N), the largest U.S. aluminum producer, to report third-quarter results that beat analysts' expectations. Still, Alcoa fell 3.1 percent to $8.85 as the biggest percentage decline on the Dow.
Chevron Corp (CVX.N) dipped 3 percent to $113.80 as the biggest drag on the S&P 500 after the second-largest U.S. oil company warned third-quarter profits would be "substantially lower" than in the previous quarter. Chevron said a hurricane and maintenance curbed its oil and gas output and a fire hit its refining operation.
Lackluster growth in China, the world's second-largest economy, is expected to rein in corporate earnings in the third quarter and dent profit forecasts as the Asian nation feels the pinch of the debt crisis in the euro zone, a key trading partner.
"You've seen very cautionary earnings results and even forward guidance. Alcoa has good earnings, but their forward guidance is lackluster. It points to a slow China and slow global growth," said Richard Weeks, managing director at HighTower Advisors in Vienna, Virginia.
The Dow Jones industrial average .DJI dropped 42.05 points, or 0.31 percent, to 13,431.48. The Standard & Poor's 500 Index .SPX shed 1.83 points, or 0.13 percent, to 1,439.65. The Nasdaq Composite Index .IXIC gained 1.18 points, or 0.04 percent, to 3,066.21.
