The difference between Chinese and U.S. stocks is only getting clearer. The S & P 500 fell into correction on Thursday for the first time since 2023 . Meanwhile, the MSCI China index has surged double digits in its best start to a year in history, largely thanks to artificial intelligence, according to Goldman Sachs. Driving Chinese market gains are what Bank of America’s Michael Hartnett calls the “Fab Four” — Baidu , Alibaba , Tencent and Xiaomi . The tech companies’ stocks are all traded in Hong Kong; Baidu and Alibaba also have U.S.-listed shares. Invoking the popularity of The Beatles reflects the momentum with which the Chinese tech giants have risen on AI hopes. Alibaba and Tencent have in recent weeks both released AI models they claim rival those from DeepSeek and OpenAI, while the Chinese tech giants each have massive user bases given their respective dominance in the country’s e-commerce and social media industries. Alibaba on Thursday unveiled an updated version of its 200 million-user Quark browser with faster AI-generated results. Baidu has built its own AI model called Ernie that it’s been rolling out across its cloud storage and content generation apps. The company also develops autonomous driving and operates robotaxis across China. Xiaomi has downplayed its AI capabilities, instead focusing on its popular SU7 electric car , a swath of smartphones and internet-connected home appliances. The stock is on pace for its ninth-straight month of gains. It’s a “Year of International – long China & EU,” Hartnett said, saying the U.S.’s ” Magnificent 7 ” is now the “Lagnificent 7.” The CNBC Magnificent 7 Index — which includes Alphabet , Amazon , Apple , Meta Platforms , Microsoft , Nvidia and Tesla — is down about 12% year to date as of Friday. Even as of March 6, the DeepSeek news had triggered $3 trillion in market cap losses for the Magnificent 7, while doubling the market cap of the Fab Four to $1.6 trillion, according to Bank of America. Since Chinese startup DeepSeek’s AI breakthrough hit markets in late January, Beijing has ramped up its supportive signals on Chinese tech, while investors have become more interested in AI announcements from Alibaba and other Chinese companies. Initial Chinese stock gains have already started to fuel expectations that the local market will see its own version of the AI-driven rally that the U.S. saw in the last two years. “In the U.S., the AI rally rotated from AI infrastructure to AI enablers and then AI adopters. It’s a similar pattern in China,” HSBC analysts said earlier this month. They noted a “large valuation gap” between Chinese AI plays versus their U.S. peers, which could narrow as growth and profits pick up. Investors inside and outside China are getting more interested. Hong Kong stocks, particularly Alibaba and Tencent, saw net buys from mainland Chinese investors reach a record high on Monday . For international institutions, short-term hedge funds led most of the buying in February, while interest from longer-term investors has started to emerge this month, Robin Xing, chief China economist at Morgan Stanley, told reporters Wednesday in Beijing. “As concerns about the U.S. economy and U.S. markets [grow], their interest may increase,” he said in Mandarin, translated by CNBC. But he cautioned it’s not a given, and said research indicates U.S. consumers may not feel much impact until a 20% drop in stocks. — CNBC’s Michael Bloom contributed to this report.

The Swiss government on Friday proposed strict new capital rules that would require banking giant UBS to hold an additional $26 billion in core capital, following its 2023 takeover of stricken rival Credit Suisse.
The measures would also mean that UBS will need to fully capitalize its foreign units and carry out fewer share buybacks.
“The rise in the going-concern requirement needs to be met with up to USD 26 billion of CET1 capital, to allow the AT1 bond holdings to be reduced by around USD 8 billion,” the government said in a Friday statement, referring to UBS’ holding of Additional Tier 1 (AT1) bonds.
The Swiss National Bank said it supported the measures from the government as they will “significantly strengthen” UBS’ resilience.
“As well as reducing the likelihood of a large systemically important bank such as UBS getting into financial distress, this measure also increases a bank’s room for manoeuvre to stabilise itself in a crisis through its own efforts. This makes it less likely that UBS has to be bailed out by the government in the event of a crisis,” SNB said in a Friday statement.
‘Too big to fail’
UBS has been battling the specter of tighter capital rules since acquiring the country’s second-largest bank at a cut-price following years of strategic errors, mismanagement and scandals at Credit Suisse.
The shock demise of the banking giant also brought Swiss financial regulator FINMA under fire for its perceived scarce supervision of the bank and the ultimate timing of its intervention.
Swiss regulators argue that UBS must have stronger capital requirements to safeguard the national economy and financial system, given the bank’s balance topped $1.7 trillion in 2023, roughly double the projected Swiss economic output of last year. UBS insists it is not “too big to fail” and that the additional capital requirements — set to drain its cash liquidity — will impact the bank’s competitiveness.
At the heart of the standoff are pressing concerns over UBS’ ability to buffer any prospective losses at its foreign units, where it has, until now, had the duty to back 60% of capital with capital at the parent bank.
Higher capital requirements can whittle down a bank’s balance sheet and credit supply by bolstering a lender’s funding costs and choking off their willingness to lend — as well as waning their appetite for risk. For shareholders, of note will be the potential impact on discretionary funds available for distribution, including dividends, share buybacks and bonus payments.
“While winding down Credit Suisse’s legacy businesses should free up capital and reduce costs for UBS, much of these gains could be absorbed by stricter regulatory demands,” Johann Scholtz, senior equity analyst at Morningstar, said in a note preceding the FINMA announcement.
“Such measures may place UBS’s capital requirements well above those faced by rivals in the United States, putting pressure on returns and reducing prospects for narrowing its long-term valuation gap. Even its long-standing premium rating relative to the European banking sector has recently evaporated.”
The prospect of stringent Swiss capital rules and UBS’ extensive U.S. presence through its core global wealth management division comes as White House trade tariffs already weigh on the bank’s fortunes. In a dramatic twist, the bank lost its crown as continental Europe’s most valuable lender by market capitalization to Spanish giant Santander in mid-April.
