NEW YORK, Jan 10 (Reuters) - U.S. stock index futures fell on Monday as renewed concerns about the euro zone sovereign debt crisis worried investors and overshadowed a number of large acquisitions.
Pressure grew on Portugal to seek financial help from the European Union and International Monetary Fund, a senior euro zone source said on Sunday, though the European Commission on Monday denied that discussions were underway on an EU/IMF bailout. For details, see [
] and [ ]Duke Energy Corp <DUK.N> agreed to buy Progress Energy Inc <PGN.N> for $13.7 billion in stock, and DuPont <DD.N> plans to buy Danisco <DCO.CO>, a Danish food ingredient firm, for $5.8 billion. [
] and [ ]Shares of Progress rose 1 percent to $45.15 in premarket trading while Duke edged 0.5 percent lower to $17.70. DuPont, a Dow component, closed at $49.76.
"We probably won't get clarity on what's going to happen in Portugal for a while," said Robert Pavlik, chief market strategist at the New York-based Banyan Partners LLC, who said that the uncertainty over Europe was causing traders "to look past these acquisition deals."
A group of private equity firms, including Apollo Global Management [
], is interested in buying Sara Lee Corp <SLE.N> and has approached the company, a source said. Sara Lee closed Friday at $17.43. [ ]S&P 500 futures <SPc1> fell 6.7 points and were below fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures <DJc1> slid 35 points and Nasdaq 100 futures <NDc1> lost 8.25 points.
Alcoa Inc <AA.N> is scheduled to report its quarterly results after the market closes, unofficially launching the fourth-quarter earnings season. The stock, a Dow component, edged 0.8 percent higher to $16.55 in premarket trading.
"Alcoa results won't suggest what we could see out of financial or tech companies, but as the first big boy to report, it sets the tone and the feeling," Pavlik said.
JPMorgan Chase & Co <JPM.N> and Intel Corp <INTC.O>, both Dow components, will report results later in the week.
February crude futures rose more than 1 percent to $89.01 per barrel after the Trans Alaska Pipeline was shut because of a leak, sparking concerns about how U.S. supply could be impacted. [
]U.S. stocks fell on Friday after a court ruling in a key foreclosures case prompted investors to pull out of bank stocks, adding to weakness after a lackluster jobs report. Despite the day's losses, the S&P 500 and Dow recorded a sixth straight week of advances.
