Wall Street succumbs to selling

Wall Street succumbed to more selling today, extending Friday’s selloff in a volatile session that saw the Dow Jones industrials drop more than 300 points, rebound and then close down more than 230.

Analysts said the sharp swings reflected investors’ uncertainty after nine weeks of declines, including Friday’s 390-point plunge in the Dow. Mixed earnings reports affected specific stocks, but failed to give the market a lift.
