Stocks traded in negative territory all day and closed lower Friday as the latest

employment report showed that the jobless rate in April reached its

highest level in almost eight years.

The

Dow Jones Industrial Average finished with a loss of 85.24 points, or 0.8%, to 10,006.63. The

Nasdaq fell 31.79 points, or 1.9%, to 1613.03, and the

S&P 500 was lower by 11.13 points, or 1%, to 1073.43.

The Labor Department issued its monthly employment report before the bell, revealing that nonfarm payrolls rose by 43,000 last month, while the unemployment rate rose to 6% from 5.7% in March. Economists were expecting the unemployment rate to rise to 5.8%, with 60,000 workers added to payrolls. The report is considered the single best measure of the overall health of the economy and will set the tone for other indicators that will be released this month.

Another economic report, the Institute for Supply Management's monthly

nonmanufacturing survey, indicated that the service sector of the economy grew again in April but at a slower pace than in the prior two months. The report follows the ISM's

factory sector data earlier this week, which showed the same trend. According to the latest report, the ISM's nonmanufacturing index fell to 55.3 last month from 57.3 in March. Analysts were expecting a reading of around 57.
