US STOCKS-Wall St set to rise on Russia bets
* Futures up: Dow 17 pts, S&P 4 pts, Nasdaq 6 pts
NEW YORK Aug 8 (Reuters) - U.S. stocks were set to rise Friday, with futures reversing earlier losses, as optimism over the Ukraine crisis offset concerns over the implications of U.S. air strikes on Iraq.
Futures had slumped overnight after President Barack Obama authorized relief supplies and air strikes on Iraq to protect fleeing Christians and minorities threatened with extermination by Islamic State fighters. The news stoked fears of another drawn-out conflict in the region.
Market participants said a rebound in U.S. stock index futures Friday was kindled by a report which said Russia was aiming to de-escalate the conflict in Ukraine.
A global gauge of equities was negative but pared losses and spot gold dipped after earlier hitting a three-week high. The yield in the 10-year Treasury note dipped below 2.35 percent for the first time since June 2013 before trading at 2.3915 - still a 14-month low.
Markets had been on tenterhooks, with the S&P 500 set to close a second week of losses, after Russia imposed bans on the import of Western foods in retaliation for sanctions over Moscow's support of Ukrainian separatists. A de-escalation of that conflict would remove a hurdle for the fragile economic recovery in Europe.
"The Russian economy is in recession to begin with and they have a very symbiotic relationship with Europe," said Art Hogan, chief equity strategist at Wunderlich Securities in New York.
"If they take the rational decision to de-escalate, that would be a positive," he said, adding that technical support and shorts covering positions could have also contributed to the rebound in futures.
S&P 500 e-mini futures were up 4 points and fair value - a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract - indicated a slightly higher open. Dow Jones industrial average e-mini futures rose 17 points and Nasdaq 100 e-mini futures added 6 points.
