Sovereign Debt and Job Worries Push Stocks Down Sharply; Dow Industrials Fall 2.6%

Two of Wall Street's biggest fears -- a deteriorating employment picture and the debt woes facing foreign governments -- re-emerged on Thursday, pushing stocks sharply lower.

The Dow Jones industrial average fell 2.6% and briefly dipped below 10,000 before closing at 10,002.18 in preliminary figures; broader indexes slid nearly 3 percent.

Thursday's trading brought hefty declines across the board, with a possible crisis in the European financial system overshadowing news of robust earnings for technology companies.
