The S&P 500 edged higher in choppy trading on Friday as Amazon results lifted the mood at the end of a week of volatile trading that saw mixed earnings from Big Tech firms and a surprise jump in US jobs growth.

The Labor Department's closely watched employment report on Friday showed nonfarm payrolls increased by 467,000 jobs last month, compared with the 150,000 jobs addition forecast by economists polled by Reuters.

The data for December was revised higher to show 510,000 jobs created, instead of the previously reported 199,000.

"Employment report really stunned markets ... not only did we have a surprisingly strong number, we had a very strong revision," said Edward Moya, senior market analyst at Oanda.

"You also have average hourly earnings coming in much hotter than expected, which is just fueling the theme that everything is just leading to more inflation."

Five of the 11 major S&P 500 sectors advanced, with consumer discretionary and energy stocks leading gains.

Fears of faster-than-expected rate hikes to curb a surge in inflation have haunted markets since the beginning of the year.
