Stocks go on a wild ride, briefly sending Dow down 1,600

NEW YORK CITY -- The Dow Jones industrial average briefly plunged nearly 1,600 points Monday as two days of steep losses for U.S. stocks brought an end to a period of record-setting calm in the market.The Dow recouped about half that loss within minutes, but its gains for the year were still gone as of late afternoon.The slump began on Friday as investors worried that creeping signs of higher inflation and interest rates could derail the U.S. economy along with the market's record-setting rally.
