In stocks, violent selling swept prices sharply lower Wednesday. Like Monday, selling was far out of proportion to the session's news, a contrast to hopes just last week that the market had grown insensitive to bad news. Losses continued to be centered in non-technologies, the group that until now had held up best during the six-week selloff. In January, hopes were strong the Dow would hold above 11,000. The Dow industrials closed below 10,000, down 318.23, or 3.1 percent, at 9972.57. The S&P 500 was down 30.95, or 2.1 percent, at 1166.71. The Nasdaq composite was down 42.69, or 2.1 percent, at 1972.09. Even during the worst of the morning selloff, the index has remained above its Monday low of 1922.78.
