Stocks ended a shortened trading session higher on Thursday, sending both the S&P 500 and Nasdaq Composite to record closing levels after U.S. employers added more jobs than expected in June.

These stocks made moves:

Tesla ended the session down slightly. Shares jumped 5% on Wednesday and snapped a six-session losing streak, even as the electric-vehicle maker posted its worst quarterly decline for deliveries in its history. The company delivered 384,122 cars in the second quarter, down 13.5% from the 444,000 cars delivered a year earlier. The results were better than Wall Street expectations and higher than the 337,000 delivered in the first quarter of 2025.

Lucid closed up 5.4%. The EV maker reported 3,309 vehicle deliveries in the second quarter, a record for any quarter, and above the 2,394 delivered in the same period a year earlier. For the first half of the year, deliveries totaled 6,418, up almost 50% from a year earlier. Competitor Rivian Automotive, meanwhile, delivered 19,301 vehicles in the first half of 2025, down almost 30% year over year. Rivian fell 4.5% on Wednesday after its deliveries numbers were released. The stock rose 1.6% on Thursday.

Datadog soared 15% after it was announced that the software maker would replace Juniper Networks in the S&P 500 index beginning July 9. Juniper was acquired by Hewlett Packard Enterprise on Wednesday. Datadog, which makes monitoring and analytics tools for developers and others, has a market capitalization of nearly $47 billion.

Nvidia rose 1.3% after the company’s next-generation artificial-intelligence chip, the Blackwell Ultra AI GPU, became commercially available. The chip maker notched a 52-week high on Thursday. CoreWeave and Dell Technologies announced Thursday the first cloud provider deployment of Nvidia’s latest GB300 NVL72 AI systems for customers.

Synopsys and Cadence Design Systems jumped 4.9% and 5.1%, respectively, after the companies said the U.S. had eased restrictions on exports of semiconductor design software to China. In a statement on its website, Synopsys said it was “working to restore access to the recently restricted products in China,” while confirming that it had been informed of the restrictions being lifted. “Synopsys is continuing to assess the impact of export restrictions related to China on its business, operating results and financials,” the company continued.

Shares of health insurer Centene fell 1.4%. The stock sank 40% on Wednesday after Centene pulled its fiscal-year earnings guidance, marking the stock’s worst daily percentage decrease on record, according to Dow Jones Market Data. New data for the insurance plans Centene sells on the Affordable Care Act exchanges showed that plan growth was lower than anticipated, the company said.

Fellow insurer Molina Healthcare, which also has exposure to the ACA exchanges, ended Thursday’s session up 0.2% after falling sharply on Wednesday. The 22% drop represented the stock’s worst one-day percentage decrease since June 7, 2012, when it fell 31%.

Tripadvisor surged 17% after The Wall Street Journal reported activist investor Starboard Value had built a stake of more than 9% in the online travel-review company. The outlet cited people familiar with the matter.

Olo rose 14% after private-equity firm Thoma Bravo reached an agreement to take the restaurant-technology provider private in an all-cash transaction with a value of about $2 billion.
