New York ? Wall Street retreated again Friday after readings on jobs and manufacturing – the first reports for the third quarter – indicated that businesses and workers still face a tough economy. The major indexes ended a turbulent week narrowly mixed.

A massive quarterly loss at General Motors Corp. and rising oil prices also gave investors reason to trade cautiously. But the market was considerably calmer than the first four sessions of the week, when the Dow Jones industrials rose or fell by triple digits each day in response to economic data or news about the financial sector.

Friday’s reports were not as poor as many analysts had anticipated, which likely accounted for the muted reaction. Nonetheless, they portrayed an economy that was still sagging as it entered the second half of the year. The Labor Department said jobs fell for the seventh straight month in July and the unemployment rate rose to 5.7 percent. The report arrived after data Thursday that showed an unexpected jump in jobless claims to a five-year high.

“It reinforces the idea that we’re seeing a steady, but not dramatic, decline in employment, which is likely to last for some time,” said Michael Sheldon, chief market strategist at RDM Financial Group in Westport, Conn.

Meanwhile, the Institute for Supply Management said manufacturing activity was flat in July. Given Thursday’s disappointing report on gross domestic product growth, Wall Street is becoming more certain that the United States is in a recession – and one that could be prolonged. U.S. recessions since World War I have lasted about 10 months, on average, but have ranged from as little as six months to as long as 16 months, Sheldon said.

There was also more bad news about construction; the Commerce Department reported that building activity declined in June. And the price of oil rose $1.02 to $125.10, retreating from an earlier gain of more than $4, but still signaling that its steep decline of recent weeks has at least temporarily been halted.

The Dow fell 51.70, or 0.45 percent, to 11,326.32. The Dow ended the week down 0.39 percent.

Broader stock indicators also lost ground Friday. The Standard & Poor’s 500 index fell 7.07, or 0.56 percent, to 1,260.31, and the Nasdaq composite index fell 14.59, or 0.63 percent, to 2,310.96.

The S&P finished the week up 0.21 percent, and the Nasdaq finished up 0.02 percent.

Bond prices edged higher in Friday’s trading. The yield on the benchmark 10-year Treasury note, which moves opposite its price, fell to 3.94 percent from 3.95 percent late Thursday. The dollar was mixed against other major currencies, while gold prices fell.
