NEW YORK (TheStreet) -- U.S. stock index futures slipped on Friday as investors digested a retail sales print that matched expectations.

Dow Jones Industrial AverageI:DJI futures were down 12 points, or 8 points below fair value, to 16,948. S&P 500I:GSPC futures fell 1.25 points, or 0.6 points below fair value, to 1,987.75. NasdaqI:IXIC futures were off 3.2 points, or 2.25 points below fair value, to 4,080.3.

U.S. stock indices finished with a lack of conviction on Thursday amid uncertainties about the U.S.'s renewed involvement in the Middle East and concerns for the direction of the global economy. 

Retail sales jumped by an as-expected 0.6% in August, and July's previously flat retail sales reading was upwardly revised to a 0.3% increase, the Census Bureau reported. The report was the most important data point of the week since last week's tepid job report.

"After a fairly weak retail sales reading in July, a snapback in August was always expected and that's what we got," said Dan Greenhaus, chief strategist at BTIG.

Import prices for August were subdued, with a 0.9% month-over-month decline.

Other U.S. reports on Friday will include the University of Michigan Consumer Sentiment index for September at 9:55 a.m. EDT and business inventories for July at 10 a.m.
