Nvidia's earnings report sparks AI stock frenzy: a "breath-catching rebound" or a "valuation reset"?

``` Nvidia’s strong performance outlook has temporarily dispelled market concerns about a bubble in the artificial intelligence industry, igniting a frenzy for AI concept stocks worldwide. However, doubts over overvaluation and investment sustainability still loom over investors like a cloud. After this much-anticipated financial report was released, the market breathed a sigh of relief. The American tech giant offered a robust revenue forecast and pushed back against views that the AI industry is in a bubble. Buoyed by this, Nvidia’s share price jumped over 5% in after-hours trading, while S&P 500 futures rose 1.3% during Asian hours. Optimism spread quickly to global markets, especially in Asia. Driven by Nvidia’s suppliers, key stock indices in South Korea, Taiwan, and Japan each rose more than 2.5%, showing renewed market confidence in the AI industry chain. Specifically, Nvidia’s Japanese chip equipment suppliers, including Tokyo Electron, Advantest, and Lasertec, all rebounded significantly. Korean memory chip manufacturers SK Hynix and Samsung Electronics also rose, with Samsung Electronics surging 6%. TSMC also rallied 4.7%, pushing the Taiwan Weighted Index to its biggest one-day gain since April 23. Gary Tan, portfolio manager at Allspring Global Investments, said Nvidia’s results indicate that “the momentum of AI infrastructure spending remains strong,” providing clear guidance for investors assessing whether to maintain exposure to AI infrastructure next year. “Relief Rally” or “Valuation Reset”? Although market sentiment is generally upbeat, some strategists warn that the current rally should not be misread as a complete removal of valuation worries. “I think this is more of a ‘relief rally’ rather than a full reset of valuation concerns,” said Dilin Wu, strategist at Pepperstone Group. “Nvidia delivered the results the market was expecting, but deeper issues remain, such as whether tech giants can effectively monetize their massive AI capital expenditures, and how long debt-driven spending can last.” This cautious view holds that while Nvidia’s earnings provide a reason to buy and have spread optimistic sentiment to other AI-related fields, underlying market concerns persist. Focus Shifts to Macro and New Supply Chains Beyond the buzz of earnings season, macroeconomic factors are returning to the focus of investors. With the outlook for the labor market unclear, bets on Fed rate cuts are weakening. “The market is currently more about removing worries rather than searching for new positives,” noted Vey-Sern Ling, Managing Director at Union Bancaire Privée. “The next focus will be on the Fed’s interest rate outlook.” Meanwhile, some analysts see new investment clues from Nvidia’s results. Allspring’s Tan suggested the report indicates, “Industry bottlenecks are shifting from chip supplies to electricity, cooling systems, and heavy equipment.” He believes, “This shift could present opportunities for traditional industrial suppliers, especially those based in Korea and China.” Risk Warning and Disclaimer The market carries risks, and investment should be approached with caution.
