U.S. stock index futures traded lower, suggesting a weaker start for Wall Street later on Monday as worries linked to a global swine flu outbreak added to U.S. bank stress-test jitters.

The Obama administration is due to publicly release the bank stress-test results on May 4. But there are fears that some of the news could start trickling out this week, raising the specter of more stock market volatility.

Governments around the world moved on Monday to contain the spread of a possible swine flu outbreak, as a virus that has killed over 100 people in Mexico spread to the United States and elsewhere.

At 0835 GMT, Dow Jones futures were down 1.9 percent, S&P 500 futures fell 1.8 percent and Nasdaq futures traded 1.5 percent lower.

German bank Helaba saw 8,190 points as key resistance for Wall Street's blue-chip Dow Jones index <.DJI>, saying a break above that level this week could trigger further upward potential.


The Dow closed at 8,076.29 points on Friday.

Overall, the fundamental environment for stock markets has turned increasingly benign (but) the swine flu ... leads to uncertainty, Helaba said.

S&P 500 companies scheduled to report quarterly earnings on Monday include Verizon Communications Inc , the No. 2 U.S. phone company, Whirlpool Corp , the world's biggest appliance maker, and wireless chip supplier QUALCOMM Inc .

Auto industry shares, notably General Motors Corp , are also expected to be in focus after news at the weekend that GM, in an effort to secure the government funding it needs to stay in business, was expected to announce a fresh round of cost cutting on Monday.

Rival automaker Chrysler LLC showed signs of progress on Sunday with its unionized workers in its battle to stay alive with just days left to complete deals to slash labor and debt costs or face bankruptcy.

The U.S. economic data calendar has the Dallas Fed's Texas manufacturing index for April at 1430 GMT and the Chicago Fed's Midwest manufacturing index for March at 1600 GMT.

Last week, the Dow Jones fell 0.7 percent and the S&P 500 index <.SPX> shed 0.4 percent, both breaking a six-week winning streak. The Nasdaq <.IXIC> rose 1.3 percent to score its seventh straight weekly advance.
