Global tech stocks climb as Nvidia results spark relief rally soothing AI bubble concerns

On Thursday, global technology stocks experienced a significant uptick, driven by a resurgence of interest in AI-related companies following impressive earnings from Nvidia. The chipmaker surpassed expectations with a staggering 62% year-on-year revenue increase, reaching $57.01 billion, and provided a robust sales forecast for the fourth quarter. This news instilled renewed confidence among investors, leading to a 5% rise in premarket trading. In Europe, the positive sentiment also impacted semiconductor firms, with Dutch companies BESI and ASMI seeing gains of over 3% and 2%, respectively. ASML, a key player in semiconductor manufacturing equipment, rose by 2.1%. Meanwhile, in Asia, stocks such as Samsung Electronics and Hon Hai Precision Industry (Foxconn) witnessed increases of 3.5% and 3.3%. Back in the U.S., the enthusiasm for tech stocks continued in premarket trading, with AMD climbing 5%, Arm increasing nearly 4%, and Micron Technology advancing by 2.7%. Other notable gains included Marvell Technology, which rose 3.3%, Broadcom at 3.1%, and Intel up by 2%. Dan Hanbury, a global equity portfolio manager at Ninety One, expressed cautious optimism about Nvidia's performance. Holding Nvidia as a key investment in his fund, he acknowledged the strong numbers but cautioned against overreacting to initial market responses. "Only three years ago, Nvidia's data center revenue was at $15 billion; now, the forecasts for next year are an astounding $280 billion," Hanbury remarked, highlighting the company's phenomenal growth trajectory. Karen McCormick, chief investment officer at Beringea, discussed the implications of large-scale investments in AI, particularly following Nvidia and Microsoft's plans to invest up to $15 billion in Anthropic, a competitor to OpenAI. McCormick noted the interconnections within the AI sector, suggesting that the substantial financial backing could create vulnerabilities if the market were to destabilize. "While the ecosystem appears strong with solid investors, the potential for a bubble raises questions about the stability of interconnected businesses if it bursts," she warned.
