NEW YORK, Oct 6 (Reuters) - U.S. stock index futures were modestly higher on Wednesday on renewed hopes for global stimulus and investors awaited data expected to show a modest return to private sector jobs growth.

The market advanced on Tuesday after the Bank of Japan unexpectedly unexpectedly cut rates closer to zero and said it would pour money into the markets through asset purchases, sparking hope for further global stimulus.

"There's a continuing realization that central banks are going to lower rates and do more quantitative easing, and just in general creating a supportive environment for equity markets," said Oliver Pursche, executive vice president at Gary Goldberg Financial Services in Suffern, New York.

In a precursor to Friday's closely watched non-farm payroll report, investors are expecting private employers return to adding jobs in September, according to the ADP Employer Services report, which is scheduled for release at 8:15 a.m. [12:15 GMT]. For details, see [ID:nN05187700]

"I don't think anything disappointing will come out in the ADP report, and a good number here will make us more optimistic for Friday," Pursche said.

Both Costco Wholesale Corp and Yum Brands Inc reported quarterly earnings that beat expectations. Yum also raised its full-year profit view, helped by strong sales in China. [ID:nSGE6950C6] and [ID:nN05259362]

The dollar stayed near eight-month lows on the euro and edged towards a 15-year trough on the yen on Wednesday, hurt by expectations of U.S. Federal Reserve easing after Japan lined up its own reflation tools.
