12:44 PM EDT, 07/19/2024 (MT Newswires) -- US equity indexes fell with crude oil, while most government bond yields rose after midday on Friday.

The Nasdaq Composite declined 0.8% to 17,737.9, with the S&P 500 down 0.6% to 5,512.6 and the Dow Jones Industrial Average 0.9% lower at 40,317.6. All sectors were down intraday except healthcare and communication services intraday.

The US 10-year Treasury yield jumped 4.6 basis points to 4.23%, and the two-year rate climbed 4.8 basis points to 4.51%.

Technology systems globally faced disruptions on Friday following a CrowdStrike ( CRWD ) system update, impacting industries from airlines to broadcasters in what probably may be the biggest-ever outage in the information technology sector.

CrowdStrike ( CRWD ) said it was "actively working with customers impacted by a defect found in a single content update for" Microsoft ( MSFT ) Windows hosts. The company has isolated the issue while "a fix has been deployed," it said, adding that the incident was not a cyberattack.

"This is being billed as the largest overall IT outage in history," Scotiabank said in a note. Shares of CrowdStrike ( CRWD ) slumped more than 11% intraday, the steepest decliner on the S&P 500 and the Nasdaq.

Further, in company news, Intuitive Surgical ( ISRG ) jumped 8% intraday, the top performer on the S&P 500 and the Nasdaq, after the robotic surgical system maker's Q2 results beat market estimates.
