Calm returned to the stock market Wednesday a day after the biggest dive this year. Stocks rose smoothly as reassuring reports on productivity and hiring overshadowed jitters about the Greek debt crisis.
The Dow Jones industrial average rose 75 points, or 0.6 percent, to 12,834 shortly before noon Eastern time. The Standard & Poor's 500 index rose 8, or 0.6 percent, to 1,351. The Nasdaq composite index rose 24, or 0.8 percent, to 2,934.
The Dow dove 203 points on Tuesday, the first hiccup in this year's strong rally. Many market-watchers believe that stocks had risen too quickly and were due for a setback. Before Tuesday, the Dow had been up more than 6 percent for the year. The Standard & Poor's 500 had been up 8.5 percent.
The sell-off was brought on by fears about the latest deadline in Greece's debt crisis. Hedge funds and banks that own Greek government debt have until Thursday night to exchange their bonds for new bonds that are less valuable. If too few are willing, Greece might default, which would rattle the global financial system.
Jerry Webman, chief economist at OppenheimerFunds Inc., said Tuesday's decline was unlikely to disrupt the market's upward momentum.
"You wouldn't expect to get it all back in one day," Webman said of Wednesday's modest gains. He said the February employment report, due out Friday, will signal whether hiring is brisk enough to offset the economic drag of high gas prices.
"There's a foot race between gas bills and paychecks," he said. "If we continue to print new paychecks at the rate we've been adding them, that mitigates a lot of the damage of higher gasoline prices."
Two encouraging signs about the labor market emerged before the market opened. The government said U.S. workers were more efficient late last year, though productivity grew more slowly than in the summer. Productivity measures output per hour worked. As productivity grows more slowly, employers might hire more workers to keep up with demand.
A closely-watched private estimate of hiring also exceeded economists' expectations. Payroll processor ADP said employers added 216,000 jobs last month. The result lifted hopes about the big February jobs report, due to be released Friday.
Investors who fear that Tuesday's decline signals the end of the four-month rally might be glad to know that the rally has survived six other 200-point drops in the Dow.
On Nov. 21, the Dow fell 248 points after a congressional committee failed to reach a deal to reduce federal spending. Two days later, it fell 236 points because of worries about the European debt crisis.
Despite those falls, the Dow is still up almost 20 percent since Oct. 3, 2011 and 4.7 percent this year. The S&P 500 index, a broader measure of the market, is up 7.2 percent for the year. Just last week, the Dow closed above 13,000 for the first time since May 2008.
Among stocks making big moves:
— Internet radio company Pandora Media Inc. dove 23 percent after its projected results for the first quarter badly missed analysts' estimates.
— Netflix rose 1.6 percent after CEO Reed Hastings recently suggested that the video streaming and DVD-by-mail company form partnerships with cable TV companies to expand its customer base. The company has about 22 million online streaming subscribers in the U.S.
— American Eagle Outfitters rose 4.3 percent. The teen clothing retailer said it expects profit margins and sales to improve this year. Revenue at stores open at least a year rose 10 percent in the fourth quarter.
