Meanwhile, oil prices fell today as consumer confidence in the United States hit an all-time low in December and home prices dropped sharply, with few signs that the real estate market has hit bottom.

Crude prices had risen for the first time in a week Monday, with the armed conflict between Israel and Palestinian militants entering a third day.

Violence in the oil-rich Middle East, however, was drowned out by more bad economic news in the United States.

Light, sweet crude for February delivery fell 79 cents to $39.23 a barrel on the New York Mercantile Exchange. The contract rose $2.31 to settle at $40.02 Monday.
