US Stocks Poised For Second Day Of Big Losses

* The decline in futures suggested that Thursday's dramatic selloff - the biggest for Wall Street in months - was poised to continue. That weakness came after data sparked worries the U.S. Federal Reserve could raise interest rates sooner than some have expected.

* Analysts expect 233,000 jobs to have been added in July, with the unemployment rate holding at 6.1 percent. The nonfarm payroll report will be released at 8:30 a.m. (1230 GMT)

* The Fed has kept overnight rates near zero since December 2008, but at its meeting on Wednesday it took note of both faster economic growth and a decline in the unemployment rate, while expressing concern about remaining slack in the labor market.

* Electric car maker Tesla Motors Inc posted second-quarter revenue that nearly doubled from the prior year, while its adjusted earnings topped expectations. Still, shares fell 1.9 percent to $219 in premarket trading. GoPro Inc shares tumbled 11 percent to $42.65 before the bell a day after reporting a bigger second-quarter net loss, pressured by rising costs.

* On the upside, LinkedIn Corp rose 6.5 percent to $192.40 in premarket trading a day after forecasting better-than-expected results in the current quarter.

* S&P 500 e-mini futures fell 11 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 e-mini futures fell 96 points and Nasdaq 100 e-mini futures lost 24.25 points.

* Thursday's decline was the biggest one-day drop for the S&P since April, and it erased monthly gains for the S&P, Nasdaq and Dow, which also turned negative for the year. The S&P closed under its 50-day moving average for the first time since April 15, a sign of weak near-term trends.

* For the week, the Dow is down 2.3 percent, the S&P is down 2.4 percent and the Nasdaq is down 1.8 percent. It is the biggest weekly decline for all three since April.

* Traders also await the final July read on manufacturing from financial data firm Markit, due at 9:45 a.m., as well as the final July read on consumer sentiment from the Thomson Reuters/University of Michigan Surveys of Consumers, due 10 minutes later and seen rising to 82 from 81.3.

* At 10:00 a.m., the Institute for Supply Management's read on July manufacturing is due and is seen rising slightly, while June construction spending is seen rising 0.5 percent.

* Investors to pay close attention to issues abroad a day after Argentina defaulted on its debt for the second time in 12 years.
