NEW YORK Hope that the Federal Reserve might consider more economic stimulus wasnt enough to keep bad news about Ireland from sinking stocks.
Irelands government bonds were downgraded by ratings agency Moodys to junk status shortly before U.S. markets closed Tuesday, sending stocks sharply lower and erasing the days gains. Ireland joins Greece and Portugal, whose debt also recently was graded as junk.
The move puts Ireland back on the list of heavily indebted European countries in danger of default. The country already has received a financial rescue package from other countries.
If a European country fails to pay its debts, it could cause widespread disruptions in financial markets and lead to a slowdown in lending. Worries about debt problems in Europe sent stocks down through the first half of June and appear to be having the same effect in July.
The Standard & Poors 500 index fell 5.85, or 0.4 percent, to close at 1,313.64. The S&P now is down 0.5 percent for the month and 2.2 percent for the week.
The Dow Jones industrial average fell 58.88, or 0.5 percent, to close at 12,446.88. The Nasdaq composite fell 20.71, or 0.7 percent, to close at 2,781. Both the Dow and Nasdaq still are up about 0.3 percent for the month.
Earlier Tuesday, minutes from the Federal Reserves last meeting June 21-22 were released. In those minutes, several Fed officials said that the government would have to consider new monetary policy to stimulate the economy, especially if growth remains too slow to reduce the unemployment rate.
That raised hopes that more economic stimulus might be on the way. The Dow rose about 60 points after the minutes were released but retreated not long after.
Stocks bounced between small gains and losses for most of the day amid worries that Italy would need help managing its debts. A successful auction of new Italian government bonds and a promise to fast-track that countrys austerity measures helped ease those fears. The news sent Milans main stock index up 1.2 percent. A default by Italy, the third-largest economy in Europe, would cause far more damage to the global financial system than one by Greece, which is a much smaller economy.
Investors also felt some relief after a meeting of 17 European finance ministers Monday resulted in a statement that implied they were open to buying distressed Greek bonds.
They are trying to staunch the bleeding, said Quincy Krosby, market strategist for Prudential Financial. That has reassured investors that there are, in essence, buyers of last resort.
U.S. financial stocks rose as tensions eased about Europes financial crisis. MBIA Inc. rose 6.9 percent after the company agreed to dismiss a lawsuit against Merrill Lynch.
Technology stocks fell after poor results from chip makers. Microchip Technology Inc. fell 4.5 percent, the most of any stock in the S&P 500 index, after the chip maker said it expected lower quarterly revenue and income because of waning demand from car makers. That pushed the stocks of other chip makers lower, too. Novellus Systems Inc. fell 11.2 percent after lowering its own profit forecast, and Texas Instruments Inc. fell 3.7 percent.
