NEW YORK (MarketWatch) -- Alcoa Inc.'s disappointing kickoff of the fourth-quarter earnings season sent U.S. stock futures lower on Tuesday.
S&P 500 futures fell 8 points to 1,134.5 and Nasdaq 100 futures fell 11.75 points to 1,871.75. Futures on the Dow Jones Industrial Average dropped 68 points to 10,536.
Stock futures maintained their losses after the government reported the U.S. trade deficit widened sharply in November. Read about rising demand in the U.S. for foreign goods.
But Alcoa /quotes/comstock/13*!aa/quotes/nls/aa (AA 15.54, -1.91, -10.95%) fell more than 7.4% in premarket trade after the aluminum producer and Dow component reported a $277 million loss that, excluding charges, was worse than analysts had anticipated. CFO Charles McLane Jr. said on a conference call that the company willingly sacrificed earnings to preserve cash.TODAY'S INTERNATIONAL MARKET STORIES

"My point is that we had to pull back capacity at many locations to meet the decreased demand," McLane said. "And the way we were going to manage our cash is to take all of the variable cash costs out as quick as possible. When you do that, you've got all your fixed costs and it's going to be over a lower volume and it's going to hurt profitability."
But analysts said Alcoa is facing the impact of currency turbulence and growing energy costs, in addition to the possibility that aluminum prices could fall.
A move by the People's Bank of China to lift the reserve requirements for banks by a half point also made an impact.
"To the extent the Chinese have been major suppliers of global liquidity, aggressive tightening is going to be very detrimental to risk assets," said Jamie Dannhauser, economist at Lombard Street Research.
