The Dow Jones industrial average (INDU) climbed 84 points, or 0.7%, to 11,859; the S&P 500 (SPX) added 5.5 points, or 0.4%, to 1,279; and the Nasdaq Composite (COMP) rose 7.6 points, or 0.3%, to 2,644.
For the week, the Dow fell 1.5%, the S&P 500 lost 1.9% and the Nasdaq dropped 2.7%. While the Dow and S&P 500 remain modestly higher for the year, this week's declines have now put the Nasdaq down 0.4% year-to-date.
Stocks were higher throughout Friday's trading session as investors welcomed two pieces of encouraging news: Libya's cease-fire and the G7's Japanese yen intervention plan.
The financial sector kept the momentum going, after the Federal Reserve gave the green light for several big banks to raise dividends and buy back shares. Among the firms to announce dividend hikes were JPMorgan Chase (JPM, Fortune 500), Wells Fargo (WFC, Fortune 500) and USBancorp (USB, Fortune 500), which each saw their shares climb.
The Libyan government announced an immediate cease-fire after the United Nations voted to impose a no-fly zone over the country. However, witnesses in the besieged city of Misrata told CNN a fierce pro-government assault was persisting.
Oil prices, which had ticked higher on the U.N. vote, turned lower after the cease-fire announcement. Crude prices fell 25 cents to $101.15 a barrel. Earlier in the session, prices neared $104.
And while Japan continues to struggle with its nuclear power plants, the Group of Seven major economic powers announced a coordinatedintervention to prevent the Japanese yen from rising further. The announcement helped the yen ease and boosted the Nikkei 2.7%.
"It's good to see leaders acting to provide stabilization in the currency market -- it gives the market confidence," said Anthony Conroy, head trader with BNY ConvergEx.
The Japanese yen had been driven sharply higher in recent days by global uncertainty and the prospect of more cash flowing into Japan.
Because Japan is heavily reliant on exports to drive its economy, a strong yen would put a difficult headwind against what is already a struggling economy, said Bill Stone, chief investment strategist with PNC Financial.
"A little weakness in the yen would be a good thing," Stone said.
