The big three indexes all hit closing highs on Tuesday, even after data released by the Bureau of Labor Statistics revealed U.S. jobs growth for the year through March was significantly lower than the government previously had reported.

These stocks made notable moves Tuesday:

Apple was down 1.5% after unveiling several new iPhones, a new series of Apple Watches, and updated AirPods at its annual product launch gathering, which the company is referring to as its “Awe Dropping” event. As anticipated, Apple watchers got a first look at the iPhone 17 Air, the company’s thinnest iPhone ever. Coming into Tuesday, Apple shares have fallen 5% this year.

Dell Technologies fell 1.4% after the maker of computers and artificial-intelligence servers said Chief Financial Officer Yvonne McGill would be resigning after 30 years with the company. Dell said McGill’s resignation wasn’t the “result of any disagreements with the company on any matter relating to its financial statements, internal control over financial reporting, operations, policies or practices.” David Kennedy, senior vice president of global business operations and finance, will serve as interim financial chief. Dell also reaffirmed its financial guidance for the third quarter and fiscal year.

UnitedHealth rose 8.6%. The managed-care company issued a securities filing that said preliminary data for the 2027 payment year from the Centers for Medicare and Medicaid Services said 78% of UnitedHealth’s Medicare Advantage members will be in plans with quality ratings of four stars or higher, on a five-star scale. The CMS manages Medicare Advantage.

Nebius jumped 49%. The Amsterdam-based company secured a $19.4 billion deal to provide Microsoft with artificial-intelligence infrastructure through 2031.

Wolfspeed surged 48% to $1.82 after the chip supplier received court approval for a restructuring plan. The company said it expects to emerge from Chapter 11 protection “in the next several weeks.”

Teck Resources rose 11% after the Canadian miner agreed to a “merger of equals” with rival Anglo American. The deal creates one of the largest copper miners in the world, with a combined market value of about $53 billion. Anglo American, which is listed in London, gained 11%.

Tourmaline Bio soared 58% to $47.64. Novartis plans to acquire the clinical biotechnology company for about $1.4 billion, paying $48 a share in cash.

Core & Main dropped 25% after the water, wastewater and drainage-supply distributor posted second-quarter adjusted earnings. Its profit beat analysts’ estimates but management reduced its guidance for the fiscal year on adjusted earnings before interest, taxes, depreciation, and amortization to $920 million to $940 million from $950 million to $1 billion. The company also cut its forecast of revenue, saying it was “operating in an environment marked by higher operating expenses and softer residential demand.”

Albemarle was down 11%. The lithium producer declined following a report from FactSet that said Chinese electric-vehicle battery maker Contemporary Amperex Technology Co. Ltd., better known as CATL, would be restarting its Yichun lithium mine. That would mean more lithium on the market, potentially weighing on prices.

SailPoint’s forecasts of adjusted earnings and revenue for the third quarter were lower than Wall Street had forecast. Shares declined 7.7%, although the cybersecurity company’s second-quarter earnings topped analysts’ estimates.

Eightco skyrocketed 3,000% Monday after it sold new stock to fund purchases of Worldcoin, the crypto token of World, a project run by OpenAI CEO Sam Altman. The shares were down 11% on Tuesday.

Planet Labs shares declined 6.6% Tuesday following an announcement it plans to sell $300 million of convertible senior notes in a private offering.

Earnings reports were expected after the closing bell from Oracle , GameStop, Synopsys, Rubrik, and AeroVironment.
