The S&P 500 and Dow index futures were little changed on Friday after a four-day slide as investors keenly awaited the government's employment report for key insight into the economy.

Investors braced for the data on June employment, due at 8:30 a.m., which likely contracted for the first time this year as thousands of temporary government jobs for census workers ended, though private-sector hiring probably picked up, according to a Reuters survey.

With mounting fears of a double-dip recession, the employment report will be closely watched for fresh insight on the strength of the U.S. economic recovery. A recent flurry of sluggish U.S. economic data and sovereign debt worries in Europe knocked down global equities while boosting the appeal of safe-haven U.S. Treasuries.

S&P 500 futures were flat and slightly below fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures rose 2 points, and Nasdaq 100 futures gained 4.5 points.
