Stocks mixed after Thursday's big rally

A quiet day on Wall Street ended Friday with major stock indexes little changed after a big rally the day before.

The Dow Jones industrial average gained 22.56 points, or 0.18 percent, to finish at 12,231.11. Stock indexes jumped more than 3 percent Thursday after European leaders unveiled a plan to expand their regional bailout fund and take other steps to contain the debt crisis in Greece.

Optimism ebbed on Friday as analysts raised questions about the plan, which left out many key details about how the fund would work. European markets mostly fell, and the euro declined against the dollar.

The Standard & Poor's 500 index rose 0.50 point, or .04 percent, to 1,285.09. The Nasdaq composite index fell 1.48, or .05 percent, to 2,737.15.

"It's a kind of sobering-up after a day of partying," said Jerry Webman, chief economist with Oppenheimer Funds in Manhattan. The Dow is up 12.1 percent this month, the S&P 13.6 percent. Both indexes are on pace to have their best month since January 1987.

There are still many obstacles to overcome with the eurozone crisis. One troubling sign: Borrowing costs for Italy and Spain increased.
