Stocks are higher, boosted by chipmakers and strong earnings: Live updates

Stocks climbed on Tuesday, supported by chipmakers, as investors looked through the latest developments in the Iran war to focus on corporate earnings updates.

The Dow Jones Industrial Average rose 340 points, or 0.7%, while the S&P 500 and the Nasdaq Composite advanced 0.7% and 1.1%, respectively.

3M shares jumped more than 9% after the industrial giant's second-quarter earnings came in better than expected. Additionally, General Motors reported a beat on the top and bottom lines for the second quarter, lifting the stock 3%. The reporting period is off to a strong start. Of the roughly 66 S&P 500 names that have reported, nearly 88% have topped bottom-line estimates, per FactSet.

Big names set to report later this week include Alphabet, IBM and Tesla.

"The next two weeks will be a defining stretch for earnings, and not just for tech," said Bret Kenwell, U.S. investment analyst at eToro. "The broader message is already clear: companies that fail to clear Wall Street's elevated bar are being punished."

"That marks a sharp contrast with last quarter, when uncertainty had lowered expectations and investors were primarily looking for reassurance that geopolitical disruption had not derailed Corporate America," he added. "Today, after the market's run to record highs, good results are not always good enough."

Semiconductors also gave a boost to the broader market. The VanEck Semiconductor ETF (SMH) gained 3%. Marvell Technology jumped around 6%, along with Astera Labs, while Micron Technology gained 7%. Intel advanced more than 5%.

Tuesday's move higher comes after a losing session in which traders weighed escalations in the U.S.-Iran war.

Central Command has carried out its 10th consecutive night of strikes on Iran since President Donald Trump declared the ceasefire "over," while Tehran's forces have struck U.S. military assets across the Middle East and its Houthi allies have declared a maritime embargo against Saudi Arabia.

Oil prices seesawed on Tuesday as Wall Street monitored a renewed diplomatic push towards mediation efforts between the U.S. and Iran. Reports suggest mediators are proposing a 10-day ceasefire between the two adversaries. West Texas Intermediate crude futures were up 2% at above $85 a barrel, while international benchmark Brent was 2% higher at above $91.

Oil had traded higher during Monday's session after President Donald Trump said in a Truth Social post that Tehran will pay for the deaths of three U.S. service members. The climb in energy prices pulled the major averages lower on the day, even as semiconductor stocks clawed back some of last week's steep losses.

SpaceX shares jump after a 7-day losing streak

SpaceX shares rose nearly 6% in morning trading Tuesday, snapping a seven-session losing streak after analysts at Macquarie reiterated their outperform rating and urged investors to buy the recent weakness.

The stock climbed to around $125, though it remains below its $135 initial public offering price following a sharp post-listing pullback.

Macquarie said the recent decline presents a buying opportunity, arguing that investors continue to underestimate the company's long-term artificial intelligence potential alongside its core space business.

"We see significant upside from AI optionality; achieving only a fraction of terminal compute ambitions could justify valuation above current levels," the analysts wrote in a note to clients.

The rebound follows a steep selloff that pushed SpaceX below its IPO price amid broader pressure on high-growth technology stocks and increasing bearish bets from short sellers. Even after Tuesday's gain, the shares remain well below the highs reached shortly after the company's public debut.

Trade Representative Greer hints at new tariffs

U.S. Trade Representative Jamieson Greer hinted that new tariffs against a slew of countries could be on the way.

In an appearance on CNBC's "Squawk Box," Greer said that he expects "to see some action soon." It came after he was asked about a Financial Times report that President Donald Trump was planning to launch new tariffs against dozens of country ahead of the expiration of his 10% global tariff.

On Monday, Trump instituted a 50% tariff against most Canadian goods. Senior Trump administration officials it was in retaliation for alleged trade discrimination of U.S. products and industries in the country.

U.S. equities began Tuesday's session in the green.

The Dow Jones Industrial Average added 212 points, or 0.4%, just after 9:30 a.m. ET. The S&P 500 rose 0.6%, while the Nasdaq Composite gained 1%.

Markets are underestimating global economic risks, Jamie Dimon says

JPMorgan Chase CEO Jamie Dimon said investors are underestimating the risks facing the global economy and that he wouldn't buy either equities or long-dated U.S. Treasurys at their current prices.

In an hourlong interview with Wilfred Frost released late Monday, Dimon said markets aren't fully accounting for a growing list of geopolitical and fiscal threats.

"I do think those risks are probably bigger than other people think," Dimon said, pointing to wars in Ukraine and the Middle East, tensions between the U.S. and China, and rising military spending in a time of mounting government deficits.

Asked whether markets are underpricing the chance of a major shock, Dimon said it's difficult to know exactly what risks are already reflected in asset prices.

"It's possible something's baked in, but what's not baked in is what actually happens," he said. Read more.

Morgan Stanley downgrades Adobe, slashes price target to $240

Morgan Stanley downgraded Adobe to underweight from equal weight, slashing its price target to $240 from $365.

Wood argued that the software maker faces mounting execution risks as it navigates several major transitions at once, adding that its best-in-class margins may be near peak as AI and low-ARPU engagement require more spending.

Markets digest surprise U.K. finance minister choice

Andy Burnham became the U.K.'s seventh prime minister in 10 years on Monday — but the appointment of his finance minister was just as closely watched as his ascent to power.

In a surprise move, former defense minister John Healey was announced as Burnham's Chancellor of the Exchequer late on Monday. Prior to the announcement, it was widely expected that Shabana Mahmood — who has been reappointed home secretary — would become Burnham's chancellor.

For months, Burnham's emergence as the frontrunner to replace Keir Starmer rattled bond traders who feared more left-leaning policies would be rolled out under his stewardship.

But yields on U.K. government bonds, known as gilts, fell across the curve on Tuesday, suggesting markets had been calmed by Healey's appointment.

"We've taken the view that Burnham's likely to be left of Starmer, and so it's going to be higher tax, lower growth, and that's tough for rate-sensitive parts of the economy," George Godber, who manages the £781 million Polar Capital UK Value Opportunities Fund, told CNBC on Tuesday.

Here’s the latest ahead of the opening bell on Wall Street

U.S. stock futures rose ahead of Tuesday's opening bell, looking poised to rebound from Monday's losing session.

Central Command carried out its 10th consecutive night of strikes on Iran since President Donald Trump declared the ceasefire "over," while Tehran's forces struck U.S. military assets across the Middle East.

Gold rose over 1% as oil prices eased, silver jumped 5%.

U.K. defense and aerospace stocks jumped on Tuesday morning after John Healey was named finance minister by new prime minister Andy Burnham.

Here are the stocks moving in premarket trading: Nebius, Calix

Nebius and Calix are among the stocks making moves before the U.S. market opens as investors look ahead to a busy earnings week, which will see Alphabet, IBM, and Tesla report.

Take a look at the key stocks making moves in premarket trading on Tuesday:

Nebius last surged nearly 6% after chip giant Nvidia disclosed a 9.3% passive stake in the AI infrastructure and cloud computing firm.

Calix, the telecommunications firm, plummeted 15% after reporting second-quarter earnings on Monday.

Silver up 5%; Gold prices rise Tuesday as oil falls

Gold and silver prices rose on Tuesday as diplomatic efforts aimed at easing the U.S.-Iran conflict got underway.

Spot gold rose 1.3% to $4,059 per ounce shortly after 4:50 a.m. ET, while U.S. gold futures for August delivery were up 1.43% to $4,067 per ounce. Spot silver prices extended earlier gains to add 5%.

It comes as analysts say uncertainty over Fed policy grows amid persistent inflation linked to the U.S.-Iran war.

"We believe the gold market is still digesting hawkish signals from Fed Chair Kevin Warsh and the fixed income market's expectations for higher U.S. policy rates," UBS wrote in a note on Monday.

"Should US economic activity surprise to the upside, with new jobs indicating a tightening labor market and oil prices edging higher, the near-term outlook for gold would remain challenging, putting prices under renewed downward pressure."

UK defense stocks rise after Healey named finance minister

Babcock International surged 7.3% in morning trade, with Qinetiq rising about 3.8%. BAE Systems rose 3.3%, and Rolls-Royce Holdings added 1.6%.

Citi analysts said in a note that investors would see Healey's appointment as a positive for the defense sector.

Healey last month quit as defense secretary following a dispute over funding for the U.K.'s armed forces. In a blow to then-prime minister Keir Starmer, Healey accusing the government of being unable to commit resources to the U.K.'s defense and security amid rising global threats.

Novartis shares jump after solid second quarter

Novartis shares rose 1.7% shortly after 8:30 a.m. in London (3:30 E.T.) after the Swiss pharma giant posted a beat on second-quarter core operating profits, amid strong sales of its cancer and multiple sclerosis treatments. It came as the rest of the European pharma sector traded broadly lower.

It comes as the drug maker continues to navigate patents expiring for key products.

Rajesh Kumar, Head of European Life Sciences & Healthcare Equity Research at HSBC hailed the company's cost controls and its execution, but told CNBC there remains a risk over its clinical trial profile.

"The main risk now is around their readout in Pelacarsen, which has been delayed from last year to now first quarter, now second quarter, now hopefully this quarter," Kumar said. "That remains the main risk... for the bull case for Novartis. It's a very well run company. Execution is solid. It's just the clinical trial profile which is a bit of a risk here."

Abu Dhabi approves $6.2 billion gas project to boost UAE supply

Abu Dhabi's National Oil Company will invest $6.2 billion to develop the Umm Shaif Gas Cap, a massive offshore oil and gas field, as part of its strategy to expand natural gas production and liquefied natural gas exports.

Disruptions in the Strait of Hormuz, usually an avenue for around 20% of the world's LNG trade, have underscored the importance of the project and highlighted the vulnerability of global energy supplies.

Umm Shaif, Abu Dhabi's longest-operating offshore field, is being developed alongside TotalEnergies, Eni and China National Petroleum Corporation.

New UK PM Andy Burnham kicks off premiership by cutting electricity bills

New U.K. finance minister Healey a ‘safe pair of hands’ amid fiscal pressure

The U.K.'s new finance minister John Healey faces a formidable fiscal challenge as Prime Minister Andy Burnham looks to reshape Britain's economic model.

Healey — who was previously the U.K.'s defense minister, having previously held a junior role at the Treasury — replaces Rachel Reeves as Chancellor, in a surprise move by Burnham. Home Secretary Shabana Mahmood had earlier been widely expected to be handed the role, but will remain in her current post.

"Healey is widely regarded as a safe pair of hands who is likely to deliver on Burnham's agenda rather than pursue an agenda of his own," said Harry Woolman, global capital markets analyst at Validus Risk Management.

New Prime Minister Burnham took office on Monday, promising a "new economic model" for Britain, with a 10-year plan involving the reindustrialization of the country, and a more collaborative approach to politics. He is expected to outline further policy measures aimed at easing the U.K.'s cost-of-living burden, and how these will be funded, in a speech later Tuesday.

"This will no doubt be high on the new Chancellor's agenda for the foreseeable future," Woolman said.

However, Sanjay Raja, chief U.K. economist at Deutsche Bank, said the U.K.'s new Chancellor faces a tighter fiscal backdrop, with the looming Autumn Budget now set to be one of the important domestic policy events for markets this year.

"Headroom appears limited, with earlier buffers partly eroded by higher rates, a softer macro-outlook and renewed geopolitical risks," Raja said. "Energy prices have eased from their peaks, but renewed upward pressure remains a key risk."

Treasury yields edge lower; analysts see room for rally despite geopolitical risks

U.S. Treasury yields edged lower across the curve on Tuesday. The benchmark 10-year Treasury yield slipped 0.6 basis point to 4.592%, while the two-year yield fell 1.1 basis points to 4.204%. The 30-year bond yield eased 0.3 basis point to 5.115%. Bond yields move inversely to prices.

BMO Capital Markets said the Treasury market has remained relatively steady despite the latest escalation in the Middle East, as signs of possible mediation tempered the initial jump in oil prices. With little U.S. economic data due this week, however, strategists warned that government bonds could remain vulnerable to abrupt moves in energy prices and developments in the Iran conflict.

"The degree to which nominal yields can decline will be tempered by the market's ongoing focus on the energy sector and geopolitical tensions," the BMO strategists said, adding that July and August inflation reports would be needed before investors could conclude that energy-driven inflation pressures had peaked.

Oil prices ease as mediation hopes offset fresh Middle East tensions

Oil prices edged lower on Tuesday as investors balanced reports that the U.S. and Iran could be exploring mediation efforts against fresh military exchanges and new threats from Yemen's Houthis to impose a naval blockade on Saudi Arabia.

U.S. crude futures for August delivery fell 0.3% to $82.98 per barrel, while international Brent crude futures for September delivery declined 0.56% to $88.72 per barrel.

"While the Houthis have not yet clarified how the blockade would be enforced, their previous campaign against commercial vessels demonstrates both the capability and willingness to disrupt Red Sea shipping," Rystad Energy senior vice president Jorge Leon wrote in a note published Tuesday.— Lee Ying Shan

China stocks slip, but Deutsche Bank sees structural tailwinds supporting second-half gains

Mainland China's CSI 300 was down 0.18%, while Hong Kong's Hang Seng index declined 0.18% in the first hour of trading.

Deutsche Bank chief investment officer for emerging markets Jacky Tang told CNBC he remains constructive on Chinese equities in the second half of the year, citing a combination of artificial intelligence, energy security investment, state-owned enterprise reforms and export-oriented companies as key tailwinds.

"We actually identified a few structural drivers to push the Chinese financial market in the second half of the year," he said, adding, "We think that China in the second half will continue to do well."

Year-to-date, the Hang Seng Index is down around 1.8% while the CSI 300 is about 0.3% lower, data from LSEG showed.

Asia-Pacific markets opened mixed on Tuesday.

Japan's Nikkei 225 added 0.8%, while the Topix rose 0.86%. South Korea's Kospi advanced 0.1% while the Kosdaq declined 0.72%.

Australia's benchmark S&P/ASX 200 was down 0.58%.

Asia markets set for mixed open as investors weigh Middle East tensions, fresh U.S. tariffs on Canada

Asia-Pacific markets were set for a mixed open on Tuesday as investors weighed rising geopolitical tensions in the Middle East, fresh U.S. tariffs on Canadian imports and higher oil prices.

Japan's benchmark Nikkei 225 was set to open higher, with the futures contract in Chicago at 64,965 against the index's last close of 64,141.12.

Futures for Hong Kong's Hang Seng index last traded at 25,099 compared to the index's last close of 25,143.05.

Futures for Australia's benchmark S&P/ASX 200 were last at 8,717 compared to its close of 8,791.3.

U.S. President Donald Trump vowed Iran would face consequences following the deaths of three American service members, while Yemen's Houthi militants announced a maritime embargo on Saudi Arabia, raising fresh concerns over energy supplies.

Separately, the Trump administration unveiled an additional 50% tariff on a range of Canadian imports, accusing Ottawa of unfair trade practices across several U.S. industries.

Trump signed three proclamations imposing the higher duties on Canadian motor vehicles, alcohol and dairy products, with administration officials saying the measures were intended to address what Washington views as discriminatory treatment of U.S. exports.

U.S. equity futures were little changed to begin trading on Monday night. Futures tied to the Dow Jones Industrial Average ticked up 12 points, or 0.02%. S&P 500 futures and Nasdaq 100 futures were down by 0.05% and 0.01%, respectively.
