At closing, the broad S&P 500-index had risen 1.0 percent, the technology-heavy Nasdaq composite index 1.2 percent and the Dow Jones industrial index 1.1 percent.
This meant that the S&P 500 closed above 6,000 points for the first time since the end of February.
In the background, the sudden and inflamed dispute between President Donald Trump and his former close associate Elon Musk, the CEO of electric car maker Tesla, was simmering.
On Thursday, during an intensified verbal exchange between the two, Tesla's stock plummeted 14.3 percent in New York.
After signs of a "ceasefire" in the dispute, Trump, in his usual clear language, dismissed reports of a peace talk.
Then, on Friday, Tesla's stock rose 3.8 percent.
Dragged others along
The company also dragged the other six highly weighted technology companies, collectively known as "The magnificent seven" – "the magnificent seven" – in the upswing.
Google owner Alphabet, e-commerce giant Amazon, iPhone manufacturer Apple, Meta (Facebook), software giant Microsoft and semiconductor giant Nvidia were all noted for more or less substantial gains.
Something that boosted market sentiment was Trump's announcement of new trade talks with China in London on Monday.
Also, new figures from the US Department of Labor affected the stock market day. They showed that 139,000 new jobs were created outside the agricultural sector in the US in May. This was more than the 126,000 expected in Bloomberg's forecast.
Unemployment in May remained unchanged at 4.2 percent compared to April, as expected.
Earlier in the week, another survey showed that significantly fewer jobs were created in the US than expected.
New debate on interest rate
In light of the job figures, the demands for the central bank Federal Reserve (Fed) to quickly lower the interest rate were raised once again. Trump floated new views that the Fed and its CEO Jerome Powell are too slow.
Among the major stock exchanges in Europe, Frankfurt fell 0.1 percent, while London and Paris rose 0.3 and 0.2 percent respectively.
The dollar strengthened during the day and a krona was traded at 9.65 against the dollar and 10.99 against the euro.
In Stockholm, trading was closed for national day celebrations.
Over the week, the S&P 500 had risen 1.5 percent, the Nasdaq composite index 2.2 percent and the Dow Jones industrial index 1.2 percent.
For Tesla, it was despite Friday's gain a dark week, with a minus 14.8 percent in the logbook.
