That helped raise market morale after a tech-driven slump in Thursday's session, as cost warnings on AI-related infrastructure from Meta Platforms and Microsoft saw the Nasdaq slump 2.7%, its worst day in nearly two months.

Nonfarm payrolls data is due later in the day, with economist polls by Reuters forecasting that the economy added 113,000 jobs in October. However, analysts said labor strikes and hurricanes could skew the month's data.

Meanwhile, Apple dropped 1.1% despite beating quarterly sales forecasts, as investors worried about a decline in China sales.

The Nov. 5 U.S. presidential election is also on investors' minds, with many analysts predicting a close race and some uncertainty over the final outcome. The Federal Reserve's November meeting kicks off the following day.

Unsurprisingly, equity volatility has risen in recent days, with the CBOE Volatility Index trading at a more than three-week high.
