Microsoft Shares Edge Up 0.2% Despite Outage as Nvidia Drags Nasdaq
Microsoft shares rose 0.2% on Friday, November 13, 2026, even as a global outage hit its web services. Wall Street still closed lower as AI stocks fell, though the S&P 500 posted a 2.5% weekly gain, its biggest since August.
Microsoft shares rose 0.2% on Friday, November 13, 2026, even though a global outage of its web services disrupted email accounts and other applications. The gain came on a day when US stocks closed lower, led down by AI-focused companies.
The S&P 500 fell 0.4%, or 30.73 points, to 7,561.67. It still gained 2.5% for the week, its first winning week since October and its biggest weekly gain since August. The index is up 10.5% so far this year.
Nvidia keeps weighing on tech
The Nasdaq composite fell 0.9%, or 229.82 points, to 25,136.27. It still notched its first weekly gain in five weeks. The Dow Jones Industrial Average recovered from an early slide and gained 0.1%, or 50.46 points, to 52,347.55.
Nvidia fell 2%. The chipmaker's chief executive, Jensen Huang, resigned a day earlier after an affair with a Chinese tech executive raised US national security concerns. Chief financial officer Colette Kress is interim CEO, and the fallout cost Nvidia more than US$600 billion in market value this week.
Broadcom fell 4.8% and Advanced Micro Devices lost 8.8%. Both had surged earlier in the week as the leadership change at Nvidia unfolded.
More than 60% of the stocks in the S&P 500 rose, but the biggest AI names carry so much weight that their slide dominated the day.
"Nvidia's pullback serves as a reminder of the concentration risk embedded in a market where a small number of mega-cap technology stocks have driven an outsized share of returns," said Angelo Kourkafas, senior global strategist at Edward Jones, in a research note.
Other movers, oil and bonds
Healthcare and financial stocks gained. Eli Lilly rose 1.3%, and payment processors Visa and Mastercard each closed 1.3% higher.
Brent crude, the international oil benchmark, jumped early before easing and settled at US$95.84 a barrel. It traded near US$72 in late February, before the Iran war began. The swings followed President Donald Trump's remark a day earlier that the US didn't "need a deal with Iran" while the Middle East conflict drags on.
In the bond market, the yield on the 10-year Treasury, which influences mortgage rates, rose to 5.15% from 5.10% late Thursday. The two-year yield edged up to 4.87% from 4.86%. European stocks were mixed.
Investors have worried for weeks about whether AI will generate enough profit to justify the costly investments and high stock values behind it. Nvidia has been slipping through that period.
