NEW YORK - A stunning makeover of the Wall Street landscape sent stocks falling precipitously Monday, with the Dow Jones industrials losing 500 points in their worst slide since the September 2001 terrorist attacks. Investors recoiled after a shakeup of the financial industry that took out two storied names: Lehman Brothers Holdings Inc. and Merrill Lynch & Co.

The pullback, which erased about $700 billion in shareholder wealth, occurred across much of the globe as investors absorbed Lehman's bankruptcy filing and what was essentially a forced sale of Merrill Lynch to Bank of America for $50 billion in stock. While those companies' situations had reached some resolution, the market remained anxious about American International Group Inc., which is seeking funding to shore up its balance sheet. A faltering of the world's largest insurance company likely would have implications far beyond that of Lehman, already the largest U.S. bankruptcy in terms of assets.

The swift developments that took place Sunday are the biggest yet in the 14-month-old credit crisis that stems from now toxic subprime mortgage debt.

For the first part of Monday's trading, the market was falling, but in a largely orderly fashion as investors seemed to draw some relief from the resolution of Lehman's problems. As the session wore on, and there was no word about AIG, the market suffered another bout of fear that the credit crisis will continue to devastate the financial sector. Selling accelerated in the final hour and then took on more momentum as stock indexes broke through lows set in July — an ominous sign for some traders.
