Wall Street retreated, pushing the Standard & Poor's 500 Index from its five-year high, as investors gear up for the fourth-quarter earnings season.
Profits at S&P 500 companies increased an average 2.9 percent in the fourth quarter, according to data compiled by Bloomberg. Excluding financial companies, earnings rose 0.5 percent.
Alcoa is the first company to report after the market closes later today. Shares were last down 1 percent.
In afternoon trading in New York, the Dow Jones Industrial Average dropped 0.58 percent, while the Standard & Poor's 500 Index shed 0.59 percent and the Nasdaq Composite Index slid 0.41 percent.
"We have a cautious market entering fourth-quarter earnings season," Peter Cardillo, chief market economist at Rockwell Global Capital in New York, told Reuters. "I think it's going to be a disappointing one this time around."
Others are more optimistic.
"I'm expecting better-than-anticipated earnings," Tom Wirth, who helps manage $US1.6 billion as senior investment officer for Chemung Canal Trust, in Elmira, New York, told Bloomberg News.
Investors who prefer to play it relatively safe can snap up US government debt this week. The US is set to auction $US32 billion in three-year notes tomorrow, $US21 billion in 10-year debt the next day and US$13 billion in 30-year bonds on Friday.
"The auctions will go well at these levels," David Ader, head of US government-bond strategy at CRT Capital Group in Stamford, Connecticut, told Bloomberg. "We're finding a footing in here. We'll probably get more of a concession."
The KBW Bank Index was last 0.4 percent lower. Ten US mortgage servicers, including Citigroup, Bank of America and JPMorgan, agreed to pay a combined $US8.5 billion under a deal that will end case-by-case reviews of foreclosures.
In a statement, Bank of America agreed to a $US11.7 billion package aimed at resolving most mortgage disputes with Fannie Mae.
Meanwhile, banks won a reprieve of four more years to meet international liquidity requirements from global central bank chiefs in an effort help propel the pace of economic recovery.
Shares of Amazon gained, last up 3 percent, after Morgan Stanley upgraded the world's largest online retailer.
In Europe, the Stoxx 600 Index ended the day with a 0.4 percent decline from the previous close, which was its highest level in nearly two years.
National benchmark stock indexes also fell in London, Frankfurt and Paris, easing 0.4 percent, 0.6 percent and 0.7 percent, respectively.
The euro, however, managed to hold above its 50-day moving average against the greenback - a positive sign. The single currency was last up 0.2 percent to $US1.3101.
"The euro simply didn't break much lower and stayed quite nicely around the US$1.30 level," Sebastien Galy, a senior foreign-exchange strategist at Societe Generale in New York, told Bloomberg. "The temptation, therefore, is to try to push it a little bit higher."
