NEW YORK (AP) -- A case of post-election nerves has sent stocks plunging as investors, again anxious about a recession, are wondering what impact a Barack Obama presidency will have on business and the overall economy.
Volatility has returned on Wall Street, with the Dow Jones industrials falling 486 points to the 9,139 level, and all the major indexes tumbling more than 5 percent.
The market was expected to give back some gains after a six-day runup that lifted the Standard & Poor's 500 index more than 18 percent.
But investors lost some of their confidence about the economy and began dumping stocks again; light volume helped exaggerate the price swings, and there was more late-day selling by hedge funds.
Analysts said the market is also growing anxious about whom Obama selects as the next Treasury Secretary, as well as whom he picks for other Cabinet positions.
