(Reuters) -U.S. stock index futures edged higher on Friday as a dip in Treasury yields provided slight reprieve, though all major indexes remained on course for weekly losses.

The benchmark 10-year Treasury note yield eased, after rising as high as 4.26% earlier in the week, and was trading around 4.198%.

Meanwhile, Tesla shares dipped 1.7% in premarket trading, following a nearly 22% surge in the previous session, as investors cheered the EV-maker's strong sales forecast.

Gains in the stock had lifted the Nasdaq and the S&P 500 on Thursday, the S&P 500's first daily advance of the week.

All three major indexes were set to snap their six-week winning streaks, with equities unsettled by a fairly rapid rise in yields as investors bet on a stronger economic outlook limiting the scope of future interest-rate cuts by the U.S. Federal Reserve.

"Even with the modest gain, investors are still very cautious as we approach a pivotal couple of weeks, which will include a raft of earnings reports, the US jobs report next week, and the US election," Deutsche Bank analysts said in a note.

"There’s been a reluctance to push the rally much further before we get some clarity on those."

Dow E-minis were up 70 points, or 0.16%, S&P 500 E-minis were up 12.75 points, or 0.22%, Nasdaq 100 E-minis were up 48.25 points, or 0.24%.

Shares of Apple dipped 0.9% after data showed iPhone sales in China fell in the third quarter. KeyBanc also downgraded the company to "underweight" from "sector weight".

Capri Holdings slumped 46.7% after a U.S. judge blocked a pending merger between the company and handbag maker Tapestry. Shares of Tapestry were up 15.7%.

Memory-chip-maker Western Digital's shares leapt 11.4% after it topped quarterly profit estimates on Thursday, while health insurer Centene advanced 14.5% after beating estimates for third-quarter profit.

A mixed set of earnings across sectors and continued uncertainty around the U.S. presidential election have also made investors cautious.

The week starting Oct. 28 promises to be a crucial one for Wall Street, with earnings from megacaps including Alphabet, Apple and Microsoft scheduled, as well as nonfarm payrolls data and the final stretch before the Nov. 5 election.

Markets have started pricing in a second Donald Trump administration in recent weeks, despite worries of a possibly contested result and whether one party will control Congress following the election.
