The Dow Jones Industrial Average plunged 336.43 points, or 3.26%, to below 10,000 -- 9988.95 -- for the first time in four years, since Oct. 29, 2004. Similarly, the S&P 500 dropped 3.66% and the Nasdaq declined 3.97%. As investors looked for safety they sold stocks and piled into government bonds.

As expected, Wall Street joined a global selloff today as the financial crisis seemed to have deepened, especially in Europe. In addition, fears of a global economic slowdown dampened investors mood further. The expected boost from the $700 billion bailout plan approved Friday was non-existent as the weekend was full of news from Europe regarding the cascading financial crisis.

The financial crisis and the economic slowdown are now hitting the next set of stocks like Aluminum giant Alcoa Inc. (NYSE: AA) -- down about 8% -- or Caterpillar (NYSE: CAT) -- down over 5% -- both companies expected to have difficulties either accessing funds or suffer from the global economic slowdown, or both. News of eBay (NASDAQ: EBAY) -- down 5.5% -- laying off over 1,000 employees didn't help, only served as a reminder of the bad employment numbers from Friday and the expected worsening conditions in the jobs market.
