Stock losses mount ahead of holidays

NEW YORK (CNNMoney.com) -- Stocks losses mounted in light trading Friday after a report showing a decline in durable goods orders overshadowed a tame inflation reading.

The Dow Jones industrial average (down 67.78 to 12,353.47, Charts), the broader S&P 500 index (down 6.62 to 1,411.68, Charts) and the tech-heavy Nasdaq composite (down 11.82 to 2,404.03, Charts) all lost about 0.5 percent with 2-1/2 hours left in the session.

The so-called Santa Claus rally that has boosted stocks this month has been slipping amid concerns about the health of the economy.

Adding to those worries Friday was a report showing durable goods orders tumbled unexpectedly in November.

The Commerce Department said orders for big-ticket items, excluding transportation, fell 1.1 percent.

That overshadowed a separate report offering a mild reading on inflation.

The inflation gauge of the Commerce Department's report on personal income and spending, known as the core PCE, was flat in December. (Full story)

"When you have a limited audience like you do today and you'll have next week, there are more dramatic moves up and down," Alfred Goldman, chief market strategist at A.G. Edwards, said.

Elsewhere, Rupert Murdoch's News Corp. (Charts) agreed to exchange its controlling stake in DirecTV Group (Charts), along with other assets and cash, for Liberty Media's $11 billion stake in News Corp. Liberty (up $4.11 to $97.75, Charts) shares jumped 4 percent.

A slew of tech companies posted earnings for the latest quarter late Wednesday.

Software company Red Hat (up $3.21 to $21.17, Charts) surged 17 percent after reporting upbeat earnings and issuing a robust forecast.

Qualcomm (down $0.76 to $37.78, Charts), a provider of microchips for mobile telephones, fell 2 percent. The company lowered its quarterly profit outlook.

BlackBerry maker Research In Motion's (down $2.94 to $130.76, Charts) reported upbeat quarterly results and raised its guidance. But shares dipped along with the broad decline in tech stocks.

Market breadth was negative. On the New York Stock Exchange, decliners topped advancers by a margin of 2 to 1 on volume of 591 million shares. On the Nasdaq, losers beat winners by a margin of 4 to 3 as 861 million shares changed hands.
