U.S. stock index futures fell in pre-market trading on Friday (7th) after data showed that the U.S. labor market was very strong in September, with most sub-data stronger than expected.

U.S. Bureau of Labor Statistics: The change in total nonfarm payrolls in July was revised up by 11,000 to 537,000 from 526,000; the total number of nonfarm payrolls in August was unchanged at 315,000. On a revised basis, employment growth in July and August combined was 11,000 higher than previously reported.

However, the year-on-year decline in average hourly earnings fell from 5.2% to 5.0%, and the monthly rate remained unchanged at 0.3%.

After the data was released, stock index futures plunged, and Dow futures fell below the 30,000-point mark; US dollar index futures jumped, returning to above the 112 mark. After the initial jump, gold confirmed a downward trend and approached the $1,700 mark.
