U.S. stock index futures edged higher Friday as investors hunkered down before a string of major technology earnings, as well as the highly-influential monthly jobs report, in the coming week. 

At 09:35 ET (13:35 GMT), the Dow Jones Industrial Average rose 175 points, or 0.4%, the S&P 500 index climbed 30 points, or 0.5% and NASDAQ Composite gained 135 points, or 0.7%. 

However, despite these gains, the indices were still on course for losses this week, which would snap six-week win streaks for all three. Risk appetite remained frail, and there has also been some profit-taking after a series of record highs earlier in October.
