The news of the day for the stock market Friday may well be out before the opening bell rings. At 8:30 a.m. EST, the Labor Department will report on nonfarm payrolls for January, a key set of data that speaks to the overall health of the economy. On average, economists believe 65,000 jobs were created in the first month of the year, while the unemployment rate is expected to remain at 5%. What's up in the air is how traders will react if the number is an outlier. A weak report could increase the chances of more rate cuts, but would also suggest the economy is in danger of a recession. At the same time, a strong report would indicate the economy is at least somewhat healthy, but could mean the Federal Reserve is more apt to hold rates steady, at least in the near term. Also on the economic calendar will be construction spending from the Census Bureau, the Institute for Supply Management's manufacturing index and the University of Michigan's consumer sentiment index. Car and truck sales are due from Ford ( F), GM ( GM), Toyota ( TM) and others. The earnings schedule will feature Chevron ( CVX), Exxon Mobil ( XOM), Nymex ( NMX), Manpower ( MAN), Gannett ( GCI) and ADP ( ADP), among others.
