NEW YORK, Aug 20 (Reuters) - U.S. stock index futures fell on Friday, tracking global equity markets lower as weaker-than-expected economic data reinforced fears of a faltering recovery.
U.S. stocks tumbled to their lowest close in nearly a month Thursday after anemic labor market and manufacturing reports indicated the recovery was losing momentum.
"Basically growth is just not there," said Dave Rovelli, a trader at Canaccord Adams in New York. "Until this administration figures out how to get people hired, we are going to be seeing a lot of these big up days, big down days, and the market's going to be all over the place."
Futures traded erratically, with S&P 500 futures falling more than 7 points in early trade, but came off their lows as the morning progressed.
S&P 500 futures <SPc1> were down 5.8 points and were 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 <DJc1> dropped 42 points, and Nasdaq 100 futures <NDc1> lost 5.50 points.
Despite declines in the last session, short-term support held, with the S&P 500 index bouncing off the 1,070 level, which represented last week's low. If the index falls through that point, the next potential support level is around 1,060.
Japan's Nikkei average <
> closed down 2 percent, hit by the weak U.S. data, which also sent the dollar slipping back toward a 15-year low.European stocks <
> dipped 0.8 percent, off for the third straight day, while world stocks as measured by MSCI <.MIWD00000PUS> were also down 1 percent.Natural resource stocks were likely to come under pressure again as U.S. crude oil futures fell 1.2 percent toward $73 per barrel. Copper fell on renewed risk aversion as investors sought perceived safe-haven assets.
Technology bellwethers Dell Inc <DELL.O> and Hewlett-Packard Co <HPQ.N> posted higher profits after the closing bell Thursday, reporting broad-based strength from corporate customers and only hints of weakness from consumers. For details, see [
]JM Smucker Co <SJM.N>, the maker of Jif peanut butter and Folgers coffee, posted quarterly profit of 86 cents per share early Friday versus the estimate. [
