NEW YORK: The upheaval in the American financial system sent shock waves through the stock market Monday, producing the worst day on Wall Street in seven years as investors digested the failure of one of its most venerable banks and wondered which domino would be next to fall.
The Dow Jones industrial average lost more than 500 points, more than 4 percent, its steepest point drop since the day the stock market reopened after the Sept. 11, 2001, attacks.
