REGULATORS VOW TO FIND WAY TO STOP RAPID STOCK DIVES Federal financial regulators forged ahead on Monday to try to prevent a repeat of last week's roller-coaster stock ride, though they had not determined the cause of the sudden, steep decline in prices on Thursday. Officials from the Securities and Exchange Commission and the major stock exchanges agreed to immediately revise marketwide circuit breakers that temporarily halt stock trading in the event of a major decline, and to draft similar measures for individual stocks that will be applied uniformly across markets. MONEY MANAGERS HAVE DOUBTS ABOUT EURO BAILOUT Markus Krygier is betting against the euro -- still. Only hours after European leaders devised a sweeping rescue package to defuse the debt crisis that has threatened the euro, Krygier, a money manager in London, arrived at his desk Monday morning confident that Europe's beleaguered currency would keep falling. He has plenty of company. Despite the nearly $1 trillion aid package assembled by the European Union, euro doubters on both sides of the Atlantic were unbowed Monday -- and preparing to make new wagers against the currency. STOCKS SOAR AFTER EUROPE ANNOUNCES RESCUE PLAN After a bruising five sessions last week that erased all of the year's gains -- including a momentary freefall on Thursday that remains largely unexplained -- stock indexes roared back on Monday. Credit markets also recovered from their malaise. Fueling the rally was an extraordinary agreement among European leaders to provide a rescue package of nearly $1 trillion to stop the spreading debt crisis. Financials received a particular jolt as fears receded, for now at least, of a default on Greek sovereign debt that might have hit the balance sheets of some big banks. OUTLET STORE IS NEW YORK BEACHHEAD FOR NORDSTROM After more than a century, Nordstrom, the upscale department store chain from Seattle, will make its Manhattan debut on Tuesday. But don't expect $4,000 dresses. Expect 25,000 pairs of discounted shoes, and an automated checkout line more at home in a supermarket than a purveyor of luxury goods. While retailers of Nordstrom's caliber typically come to New York to erect sumptuous flagships, Nordstrom is introducing itself with a low-cost sister store in Union Square -- mere steps from Filene's Basement. DISCLOSURE OF SUIT WARNING WEAKENS SHARES OF MOODY'S Shares of Moody's fell sharply on Monday after it disclosed that the Securities and Exchange Commission had warned that it might sue the firm for making 'false and misleading' statements as part of its application as a ratings organization. The company said that the warning stemmed from actions by members of a European rating surveillance committee who 'may have violated Moody's professional code of conduct,' according to a spokesman, Michael N. Adler. Moody's reported the incident to the SEC in 2008, Adler said in a statement. LAHOOD SEES A CHANGE OF ATTITUDE AT TOYOTA Toyota faced 'very, very serious credibility problems' in the wake of its safety crisis, but changed its attitude toward American regulators after its president, Akio Toyoda, visited the United States, Transportation Secretary Ray LaHood said Monday. Speaking after a meeting with Toyoda at the company's headquarters in Japan, LaHood said his department was looking through 500,000 pages of documents to determine whether to levy additional fines against the Japanese carmaker, a process that could take months.
