NEW YORK (AP) — The stock market keeps getting tossed around by the Fed.
Stocks opened lower Friday but reversed course after a letter surfaced from Federal Reserve Chairman Ben Bernanke, suggesting there was room for the central bank to do more to help the economy.
"There is scope for further action by the Federal Reserve to ease financial conditions and strengthen the recovery," Bernanke wrote to California Rep. Darrell Issa, a Republican, in a letter obtained by The Wall Street Journal.
The Dow Jones industrial average was down 30 points at its low but was up 99 at 13,156 with a half-hour of trading to go. The Standard & Poor's 500 index was up nine to 1,411. The Nasdaq composite index rose 18 to 3,071.
In a typically slow August week, without much else to influence trading, investors have grasped for hints about what the Fed might do.
On Wednesday afternoon, investors pushed stocks higher after the Fed released meeting minutes that appeared to signal it was ready to take more action to prop up the economy.
On Thursday, stocks declined when a Fed regional bank president cast doubt on the idea, saying in an interview with CNBC that the economic recovery appeared to be gaining strength.
Then on Friday, Bernanke shook up the market again. His letter was in response to questions from Issa, the head of the House oversight committee, who had asked whether it was premature to consider additional steps.
The Fed has several options, including buying bonds, as it has done twice since the 2008 financial crisis, to try to lower interest rates and drive investors into the stock market.
Still, it's debatable how much future Fed action would help the market or the economy. On Friday, some analysts thought it strange that the market moved so decisively on just an inkling about what the Fed chairman might be thinking.
"What's new about what came out?" said Ann Miletti, senior portfolio manager at Wells Fargo Advantage Funds in Milwaukee. "I guess the markets are dependent on having some commentary about the macro economy every single day."
For the most part, the market has been hard to read this month. Without much news, trading volume has been low, and investors haven't had much conviction either way about the economy.
Of 17 trading days in August, only once has the Dow moved more than 1 percent. On five days, it has been virtually flat, moving less than one-tenth of a percentage point.
The turbulence likely lies ahead. The Fed's annual meeting in Jackson Hole, Wyo., is at the end of the month. German courts are set to decide next month whether the country can keep participating in bailouts for weaker European countries.
And the presidential election in November, which will help determine whether taxes go up and government spending is cut next year, could throw the markets into turmoil for weeks beforehand.
"People look forward to a lot of questions being answered in the months ahead," said Tony Fratto, a former aide to President George W. Bush and managing partner at Hamilton Place Strategies in Washington. "But they don't have answers today."
This is still likely to be the first down week for the Dow and the S&P 500 after six weeks of gains. The economic reports that have trickled out this week have been mixed at best.
Europe, though quiet, still showed signs of tension Friday. Britain reported that its economy shrank in the second quarter, the latest confirmation that the country is still in recession.
The Greek prime minister met with his German and French counterparts to discuss Greece's bailout. Greek Prime Minister Antonis Samaras said Greece needs "time to breathe" while it implements spending cuts that Germany is demanding. German Chancellor Angela Merkel replied that Germany expects Greece to follow through with its commitments, "that deeds follow words."
Durable goods orders, reported by the Commerce Department, rose in July but fell after excluding gains from the volatile transportation category. Durable goods are an important measure of economic health because those orders show whether businesses are willing to spend to expand or improve.
