Big Tech and other superstars of the US stock market are rallying on Monday, as Wall Street recovers much of its loss from last week.

The S&P 500 climbed 1.2% to claw back more than two-thirds of its first weekly loss in the last four. The Dow Jones Industrial Average was up 183 points, or 0.4%, as of 10:15 a.m. Eastern time, and the Nasdaq composite was 1.9% higher.

Nvidia was by far the strongest force pushing the market upward and rose 4%. It and other winners in the frenzy around artificial-intelligence technology had been at the center of last week’s drop. Critics say their stock prices shot too high and too fast in the mania around AI, drawing comparisons to the 2000 dot-com bubble that ultimately burst.

Taiwan Semiconductor Manufacturing Co., which makes chips for Nvidia and other companies, saw its stock that trades in United States rise 3.1% after saying its revenue climbed nearly 17% in October from a year earlier. While such growth is strong compared with other companies, it’s a slowdown from TSMC’s earlier performance.

Another AI darling, Palantir Technologies, jumped 8% for the biggest gain in the S&P 500.

The gains for tech helped offset losses across much of the rest of the market, as the majority of stocks within the S&P 500 index sank.

Health insurers fell as uncertainty remains about whether Washington will extend expiring health care tax credits, a sticking point in the disagreement on Capitol Hill that's created the longest-ever shutdown for the US government.

That's even though the Senate took the first steps on Sunday to end the shutdown.

President Donald Trump suggested in a social media post over the weekend — with few details — that the subsidies being sent to the “money sucking” insurance companies should instead be sent directly to people so they can buy their own health insurance.

Humana fell 2.6%, and Cigna slipped 0.7%, The AP news reported.

The effects of the government's shutdown have become more apparent following the cancellations of thousands of flights over the weekend. Towers are facing shortages as some air traffic controllers — unpaid for weeks — have stopped showing up for work.

Besides the pain at airports, the US government’s shutdown has also delayed many important reports on the economy. A resumption could upset financial markets if the released logjam shows data that dashes traders’ expectations for coming cuts to interest rates.

The wide expectation is that the Federal Reserve will continue to cut its main interest rate in hopes of shoring up what has been a slowing job market. Wall Street loves lower interest rates because they can give the economy a boost while also pushing prices for investments upwards.

But the Fed has said it may have to halt its cuts if inflation worsens because lower interest rates can give inflation more fuel.

Without updates from the US government on jobs and the economy, traders have been trawling profit reports from companies for clues about how things are going.

Tyson Foods, which sells chicken and other meat, climbed 2.1% after reporting a stronger profit for the latest quarter than analysts expected. It benefited from increases in prices of 11% to 17% for its beef and pork.

Roughly four out of every five companies in the S&P 500 have also been reporting stronger profits for the summer than analysts expected. Companies usually top analysts’ profit expectations each quarter, but the pressure was high this time around because they needed to justify the big moves upward their stock prices have made since April.

Delivering bigger profits is one of the easier ways they can quiet criticism that their stock prices have become too expensive.

Companies have also been giving generally strong forecasts for upcoming results, according to Bank of America strategist Savita Subramanian. That has analysts' overall expectations for earnings in 2026 nearly all the way back to where they were before Trump shocked the economy and financial markets with his “Liberation Day” announcement of worldwide tariffs.

In stock markets abroad, indexes rallied across much of Europe and Asia.

South Korea’s Kospi jumped 3% for one of the bigger gains. Chip company SK Hynix, which is cooperating with Nvidia on artificial intelligence, leaped 4.5%. Its bigger rival, Samsung Electronics, climbed 2.8%.

In the bond market, the yield on the 10-year Treasury edged down to 4.10% from 4.11% late Friday.

Researchers at the Paul Scherrer Institute PSI have achieved a breakthrough on the path to practical application of lithium metal all-solid-state batteries.

The team expects the next generation of batteries to store more energy, are safer to operate, and charge faster than conventional lithium-ion batteries.

The team has reported these results in the journal Advanced Science.

All-solid-state batteries are considered a promising solution for electromobility, mobile electronics, and stationary energy storage – in part because they do not require flammable liquid electrolytes and therefore are inherently safer than conventional lithium-ion batteries.

Two key problems, however, stand in the way of market readiness: On the one hand, the formation of lithium dendrites at the anode remains a critical point.

On the other hand, an electrochemical instability – at the interface between the lithium metal anode and the solid electrolyte – can impair the battery’s long-term performance and reliability.

To overcome these two obstacles, the team led by Mario El Kazzi, head of the Battery Materials and Diagnostics group at the Paul Scherrer Institute PSI, developed a new production process:

“We combined two approaches that, together, both densify the electrolyte and stabilize the interface with the lithium,” the scientist explained.

Central to the PSI study is the argyrodite type LPSCl, a sulphide-based solid electrolyte made of lithium, phosphorus, and sulphur. The mineral exhibits high lithium-ion conductivity, enabling rapid ion transport within the battery – a crucial prerequisite for high performance and efficient charging processes.

To densify argyrodite into a homogeneous electrolyte, El Kazzi and his team did incorporate the temperature factor, but in a more careful way: Instead of the classic sintering process, they chose a gentler approach in which the mineral was compressed under moderate pressure and at a moderate temperature of only about 80 degrees Celsius.

The result is a compact, dense microstructure resistant to the penetration of lithium dendrites. Already, in this form, the solid electrolyte is ideally suited for rapid lithium-ion transport.

To ensure reliable operation even at high current densities, such as those encountered during rapid charging and discharging, the all-solid-state cell required further modification.

For this purpose, a coating of lithium fluoride (LiF), only 65 nanometres thick, was evaporated under vacuum and applied uniformly to the lithium surface – serving as a ultra-thin passivation layer at the interface between the anode and the solid electrolyte.

In laboratory tests with button cells, the battery demonstrated extraordinary performance under demanding conditions.

“Its cycle stability at high voltage was remarkable,” said doctoral candidate Jinsong Zhang, lead author of the study.

After 1,500 charge and discharge cycles, the cell still retained approximately 75% of its original capacity.

This means that three-quarters of the lithium ions were still migrating from the cathode to the anode. “An outstanding result. These values are among the best reported to date.”

Zhang therefore sees a good chance that all-solid-state batteries could soon surpass conventional lithium-ion batteries with liquid electrolyte in terms of energy density and durability.

Thus El Kazzi and his team have demonstrated for the first time that the combination of solid electrolyte mild sintering and a thin passivation layer on lithium anode effectively suppresses both dendrite formation and interfacial instability.

This combined solution marks an important advance for all-solid-state battery research – not least because it offers ecological and economic advantages: Due to the low temperatures, the process saves energy and therefore costs.

“Our approach is a practical solution for the industrial production of argyrodite-based all-solid-state batteries,” said El Kazzi. “A few more adjustments – and we could get started.”

Meta Urges Australia to Change Teen Social Media Ban

Tech giant Meta urged Australia on Monday to rethink its world-first social media ban for under-16s, while reporting that it has blocked more than 544,000 accounts under the new law.

Australia has required big platforms including Meta, TikTok and YouTube to stop underage users from holding accounts since the legislation came into force on December 10 last year.

Companies face fines of Aus $49.5 million (US$33 million) if they fail to take "reasonable steps" to comply.

Billionaire Mark Zuckerberg's Meta said it had removed 331,000 underage accounts from Instagram, 173,000 from Facebook, and 40,000 from Threads in the week to December 11.

The company said it was committed to complying with the law.

"That said, we call on the Australian government to engage with industry constructively to find a better way forward, such as incentivizing all of industry to raise the standard in providing safe, privacy-preserving, age appropriate experiences online, instead of blanket bans," it said in statement.

Meta renewed an earlier call for app stores to be required to verify people's ages and get parental approval before under-16s can download an app.

This was the only way to avoid a "whack-a-mole" race to stop teens migrating to new apps to avoid the ban, the company said.

The government said it was holding social media companies to account for the harm they cause young Australians.

"Platforms like Meta collect a huge amount of data on their users for commercial purposes. They can and must use that information to comply with Australian law and ensure people under 16 are not on their platforms," a government spokesperson said.

Meta said parents and experts were worried about the ban isolating young people from online communities, and driving some to less regulated apps and darker corners of the internet.

Initial impacts of the legislation "suggest it is not meeting its objectives of increasing the safety and well-being of young Australians", it said.

While raising concern over the lack of an industry standard for determining age online, Meta said its compliance with the Australian law would be a "multilayered process".

Since the ban, the California-based firm said it had helped found the OpenAge Initiative, a non-profit group that has launched age-verification tools called AgeKeys to be used with participating platforms.

China can narrow its technological gap with the US driven by growing risk-taking and innovation, though the lack of advanced chipmaking tools is hobbling the sector, the country's leading artificial intelligence researchers said on Saturday.

China's so-called "AI tiger" startups MiniMax and Zhipu AI had strong debuts on the Hong Kong Stock Exchange this week, reflecting growing confidence in the sector as Beijing fast-tracks AI and chip listings to bolster domestic alternatives to advanced US technology.

Yao Shunyu, a former senior researcher at ChatGPT maker OpenAI ‌who was named ‌technology giant Tencent's chief AI scientist in December, ‌said ⁠there was a ‌high likelihood of a Chinese firm becoming the world's leading AI company in the next three to five years but said the lack of advanced chipmaking machines was the main technical hurdle.

"Currently, we have a significant advantage in electricity and infrastructure. The main bottlenecks are production capacity, including lithography machines, and the software ecosystem," Yao said at an AI conference in Beijing.

China has completed a working prototype of an extreme-ultraviolet lithography ⁠machine potentially capable of producing cutting-edge semiconductor chips that rival the West's, Reuters reported last month. However, the ‌machine has not yet produced working chips and may ‍not do so until 2030, people with ‍knowledge of the matter told Reuters.

MIND THE INVESTMENT GAP

Yao and other ‍Chinese industry leaders at the Beijing conference on Saturday also acknowledged that the US maintains an advantage in computing power due to its hefty investments in infrastructure.

"The US computer infrastructure is likely one to two orders of magnitude larger than ours. But I see that whether it's OpenAI or other platforms, they're investing heavily in next-generation research," said Lin Junyang, technical lead for Alibaba's flagship Qwen large language model.

"We, ⁠on the other hand, are relatively strapped for cash; delivery alone likely consumes the majority of our computer infrastructure," Lin said during a panel discussion at the AGI-Next Frontier Summit held by the Beijing Key Laboratory of Foundational Models at Tsinghua University.

Lin said China's limited resources have spurred its researchers to be innovative, particularly through algorithm-hardware co-design, which enables AI firms to run large models on smaller, inexpensive hardware.

Tang Jie, founder of Zhipu AI which raised HK$4.35 billion in its IPO, also highlighted the willingness of younger Chinese AI entrepreneurs to embrace high-risk ventures - a trait traditionally associated with Silicon Valley - as a positive development.

"I think if we can improve this environment, ‌allowing more time for these risk-taking, intelligent individuals to engage in innovative endeavors ... this is something our government and the country can help improve," said Tang.
