Dow Industrials Post First Close Below 10,000 Since Nov. 4

Stocks fell broadly on Wall Street on Monday on concerns about government debt in Europe, and the Dow Jones industrial average closed below the 10,000 mark for the first time since Nov. 4.

The Dow industrials were down 103.69 points, or 1 percent, at 9,908.54 at the closing bell. The Standard & Poor's 500-stock index and the Nasdaq were also lower for the day.

Shares of financial firms posted the largest losses amid worries that they could be hurt by huge deficits in countries like Greece, Spain, and Portugal.
