Friday session on the Dow Jones Index closed 0.16% lower.

And for the week overall, it lost 0.4%.

But the S&P 500 closed up 0.80% and gained 0.6% for the week.

And the NASDAQ rallied 1.6% on Friday.

The weekly gain there is 1.5%.

If we take a closer look at what happened there to deliver those record high closes for the S&P 500 and the NASDAQ, well, reporting season is still underway and it will be this week too.

Over one third of S&P 500 companies are due to post results.

And of course, ongoing uncertainty from the US-Iran war has been weighing on investors' minds, not only about the status of the fragile ceasefire, which had an impact at the start of last week, but also about whether another round of peace talks would occur and optimism surrounding that.

So

The S&P 500 and NASDAQ have now risen four weeks in a row.

Tech shares buoyed by strong results from Intel helped lift things on Intel.

It surged 23.65% to close at a record $82.57 and was the best performer on the benchmark S&P index following a better than expected revenue forecast for the second quarter.

This surge takes Intel past its dot-com era peak from the year 2000.

Fellow chipmakers AMD and ARM both shot higher.

MegaCap NVIDIA climbed 4.32% and also closed at a record as it neared the US$5 trillion market valuation again.

As for the underperforming sectors for the week, healthcare down 3.1%.

financials, which were 1.9% lower, and real estate, which dropped 1.5%.

Moving on to US Treasury yields, they dipped on hopes that US-Iran peace talks could take place over the weekend, bolstering confidence that the war could be close to ending.

The yield on benchmark US 10-year notes fell 1.7 basis points to 4.31%.

The two-year note yield, which typically moves in step with interest rate expectations for the Federal Reserve, fell 4.5 basis points to 3.78%.
