Sept 7 (Reuters) - U.S. stock index futures were little changed on Wednesday as investors seek more clues on the timing of the next interest rate hike.
* The Nasdaq closed at a record level on Tuesday, while the S&P 500 and the Dow edged up after weak services data raised doubts about the ability of the U.S. economy to absorb a rate hike.
* The dollar index was trading flat on Wednesday after falling more than 1 percent a day before. Oil prices also regained some strength, rising about 0.75 percent.
* Analysts say the Federal Reserve has been prepping the markets for a possible hike in December. However, a recent spate of disappointing economic data, including last week's jobs numbers, could scuttle those plans.
* Traders have priced in a 15 percent chance of a hike when the Fed meets later this month and a 45.7 percent chance of a move in December, according the CME Group's FedWatch too.
* The central bank is scheduled to release its Beige Book, a summary of commentary on economic conditions on Wednesday, which investors will parse for rate-hike clues.
* The U.S. Labor Department will release a report on monthly job openings and layoffs at 10:00 a.m. ET (1400 GMT). The report will give more insight into the labor market.
* Apple shares were up 0.40 percent at $108.13 in thin premarket trading. The world's most valuable public company is expected to unveil the new iPhone 7 later on Wednesday.
* Chipotle rose 6.3 percent to $439.75 after activist investor William Ackman's hedge fund Pershing Square bought a 9.9 percent stake in the burrito chain operator.
