A look at some highlights from the day's business news:
Stocks post gains despite Egypt unrest
U.S. stocks posted solid gains Monday as investors focused on the positive earnings news out of Exxon Mobil and rising commodity prices, while continuing to monitor the ongoing political unrest in Egypt.
At the final close on Monday, the Dow Jones industrial average rose 68 points, or 0.6%, to 11,892 the S&P 500 index added 9.8 points, or 0.8%, to 1,286 and the Nasdaq Composite was up 13.2 points, or 0.5%, to 2,700.
Energy shares led the Dow higher, led by Exxon Mobil, which reported a 46% jump in fourth-quarter earnings. Chevron rose 1.7%. That helped lift the Select Sector Energy Select Sector SPDR Fund, an energy ETF that counts Exxon and Chevron among its top holdings.
Oil prices continued to trend higher amid the ongoing tensions in Egypt. Crude prices spiked more than 4% Friday on worries about potential disruptions to shipments through the Egypt-controlled Suez Canal. Oil prices gained 2.9% to
settle at $92.19 a barrel on Monday. That marked its highest close since Oct. 2, 2008.
Intel cuts profit margin outlook on chip error
Intel has discovered an issue with a newly released support chip, and fixing the problem will cut revenue by $300 million in the first quarter.
The company added that its gross profit margins for first quarter of 2011 and the full year will also take a hit. Shares fell on the news.
In a press release Monday morning, Intel said it had found that the ports within its 6 Series support chip (code-named Cougar Point) "may degrade over time." The issue could affect the performance or functionality of devices
linked to those ports, like hard disk drives and DVD drives.
Intel warned it expects first-quarter revenue to be reduced by $300 million as a result - but added that full-year revenue "is not expected to be materially affected."
Intel stock was initially halted on the news, and shares were down about 1% in the late morning after trading resumed - but they ended flat at $21.46.
Meanwhile, shares of rival chipmaker Advanced Micro Devices spiked 4.5%.
Bond prices pull back
Treasury prices were slightly lower Monday and yields rose as investors took a break from last week's bond-buying frenzy.
The benchmark 10-year note fell, driving its yield up to 3.34%. Prices and yields move in opposite directions.
The 30-year bond's yield rose to 4.55%. Yields on the 2-year note rose to 0.56% and the 5-year note increased to 1.93%.
Traders are closely watching the political uprisings in Egypt and looking ahead to economic data out later this week, said Kim Rupert, a fixed income analyst with Action Economics.
"There are several economic reports and events this week, keeping further buying on the sidelines. The market is taking sort of a wait-and-see mode right now," she said.
