Stocks mostly down as traders look to earnings

NEW YORK -- Stocks closed broadly lower Monday in the final trading session before first-quarter earnings season gets under way.

Traders are concerned about the effect of higher oil and food costs on corporate margins. Stocks turned lower in afternoon trading after the International Monetary Fund said that higher gas prices could slow the pace of the U.S. economy and offset the boost from the Federal Reserve's bond-buying stimulus program.

After the market closed, Alcoa Inc. reported a first-quarter profit on higher aluminum prices and sales, partially offset by a weaker dollar and higher energy and raw materials costs. The results fell short of expectations. Alcoa is traditionally the first of the 30 companies that make up the Dow average to report earnings each quarter.

-- The Dow Jones industrial average rose 1.06, less than 0.1 percent, to 12,381.11.

--The S&P 500 index fell 3.71, or 0.3 percent, to 1,324.46.

--The Nasdaq composite fell 8.91, or 0.3 percent, to 2,771.51.

Level 3 to acquire rival Global Crossing for $2B

WASHINGTON -- Level 3 Communications Inc. said Monday that it is buying Global Crossing Ltd. for $2 billion, joining two major long-distance telecommunications networks that carry massive amounts of Internet and other data traffic in the U.S. and internationally.

Both Level 3 and Global Crossing operate vast networks of optical fiber used by other telecom carriers, corporations and government agencies. The combined company's reach would extend to 70 countries on three continents.

Despite steadily increasing data traffic, the prices Level 3 and companies like it can charge for carrying that traffic have been driven down by competition, said Erik Kreifeldt, a senior analyst at TeleGeography. Meanwhile, the carriers have high fixed costs, including the cost to lay fiber-optic cables on the bottom of the ocean.

Kreifeldt said the acquisition will help Level 3 gain scale, enabling it to put more traffic over its networks.

Kindle price to drop, but ads will go on devices

SAN FRANCISCO -- Amazon.com Inc. is dropping the price on its Kindle e-reader, but the change comes with a trade-off: On-screen ads.

The online retailer was set to announce today that the new Kindle with Special Offers will cost $114 -- $25 less than the currently lowest-priced Kindle -- and include advertisements on the bottom of the device's home page and on its screen savers. Amazon will start shipping the newest Kindle on May 3, and it also will be sold in Target and Best Buy stores on that date.

Amazon has consistently lowered the price of the Kindle since it released the first version of the device at $399 in 2007, though this is the first time it is doing so while including ads on the e-reader.
