Wall Street hit levels not seen since 2003 on Wednesday, with the Dow Jones industrial average plunging below the 8,000 mark amid a dour economic outlook from the Federal Reserve and worries over the fate of Detroit's three automakers. A cascade of selling occurred in the final minutes of the session as investors yanked money out of the market. For many, the real fear is that the recession might be even more protracted if Capitol Hill is unable to bail out the troubled auto industry. Investors also scoured economic data that included minutes from the last meeting of the Federal Reserve in which policymakers lowered projections for economic activity this year and next. Economic worries caused across-the-board selling, with financial stocks particularly hard hit. The S&P 500, widely considered the broadest snapshot of corporate America, slipped 52.54 points, or 6.12 percent, to 806.58; and the Dow gave up 427.47 points, or 5.07 percent, to 7,997.28. Both closed at their lowest levels since March 2003, and are rapidly approaching the lows of the 2000 to 2002 bear market.
