New York - US stock index futures were little changed on Friday on caution ahead of the key US non-farm payrolls report for April.
The payrolls report due out at 14:30 is expected to show US hiring likely increased at its quickest pace in five months in April, which would bolster hopes of a strong rebound in economic activity in the second quarter.
Employers probably added 210 000 jobs last month after increasing headcount by 192 000 in March, according to a Reuters poll. That would also beat the pace of payrolls gains in the first quarter of 177 667 jobs per month.
Data released on Thursday showed the number of Americans filing new claims for unemployment benefits unexpectedly rose last week, but the underlying trend continued to point to improving labour market conditions.
