A look at highlights from the day's business news:
Dow breaks 8-week winning streak
Stocks tumbled Friday after reports that Goldman Sachs is facing a criminal probe sparked analyst downgrades and a selloff in the financial sector. Worries about Greece's lingering debt problems also weighed.
The Dow Jones industrial average lost 159 points, or 1.4 percent, according to early tallies. The S&P 500 index lost 20 points, or 1.7 percent. The Nasdaq composite lost 50 points or 2 percent.
Stocks had seesawed in the early going but soon turned lower after ratings agency Standard & Poor's downgraded Goldman Sachs following reports it is the target of a criminal investigation by federal prosecutors.
Dollar falls as investors await Greek aid package
The dollar fell against the euro Friday as investors gravitated toward more risky assets amid signs an aid package for Greece may be announced over the weekend.
The dollar was down 0.5 percent against the euro to $1.3314 and was up 0.15 percent versus the U.K. pound at $1.5299. Against the Japanese yen, the dollar fell 0.1 percent to ¥93.93.
The euro was boosted by speculation that officials from the European Union and International Monetary Fund could announce a bailout for Greece on Monday.
Greece has reportedly agreed to additional austerity measures, at the behest of Germany, in order to receive an emergency bailout package that could total $159 billion over three years.
Bad news for Goldman and Greece, good for bonds
Treasury prices rose Friday, as investor worries grew about Greece's aid package and a credit rating agency downgraded Goldman Sachs stock.
What prices are doing: The benchmark 10-year note rose 18/32 to 99-23/32, driving the yield down to 3.67 percent. Bond prices and yields move in opposite directions.
The 30-year bond rose 1-2/32 to 101-20/32 with a 4.53 percent yield. The 2-year note inched up to 100-2/32 with a 0.97 percent yield. The 5-year note rose 10/32 to 100-12/32 with a yield of 2.43 percent.
What's moving the market: Treasurys have been in push-and-pull mode all week, influenced by news about the Goldman Sachs hearings, the Federal Reserve's announcement on interest rates, credit downgrades of Greece, Portugal and Spain, and positive reports about the U.S. economy.
Oil prices rise again
Oil prices jumped Friday for the third straight day as optimism about the economic recovery and a weaker dollar boosted the appeal of crude.
Traders said the massive oil spill in the Gulf of Mexico was having little impact on current prices, but could be a impetus toward higher prices in the near future if it leads to a curtailment of offshore drilling.
What prices are doing: Crude for June delivery climbed 98 cents, or 1.1 percent, to settle at $86.15 a barrel, a three-week high.
Prices plummeted earlier in the week after Greek, Portuguese and Spanish sovereign debt were downgraded. Though up only marginally in the past week, crude is more than 70 percent higher than this time last year.
What's moving the market: Following a whirlwind of bad news out of Europe early in the week, crude prices rallied as optimism, fueled by the Fed's rate decision and upbeat economic data, seeped back into the market. The dollar also weakened, boosting the appeal of crude.
