Group 1: Market Overview - The US stock market experienced a significant adjustment on November 18, with all three major indices closing lower, led by a decline in technology stocks. The Dow Jones Industrial Average fell by 498.5 points, a decrease of 1.07%, closing at 46091.74 points; the S&P 500 dropped by 0.83% to 6617.32 points; and the Nasdaq Composite Index decreased by 1.21%, ending at 22432.85 points. Concerns over technology stock valuation bubbles and a cooling expectation for Federal Reserve interest rate cuts exerted dual pressure on the market [1][2]. Group 2: Technology Sector Performance - The technology sector faced severe losses, with major tech stocks generally declining. Amazon's stock plummeted by 4.43%, resulting in a market value loss of approximately 784 billion RMB, making it one of the most significant losers among tech giants. Additionally, semiconductor leader Nvidia fell by 2.81%, and software giant Microsoft dropped by 2.70%. The Philadelphia Semiconductor Index also declined by 2.31% [2]. - The market showed a mixed performance among popular Chinese concept stocks, with the Nasdaq Golden Dragon China Index rising by 0.42%. iQIYI saw a notable increase of over 6%, while Pinduoduo's stock fell by more than 7% due to slowing growth, making it one of the largest decliners among Chinese concept stocks. Analysts noted that 45% of fund managers view the "AI bubble" as the biggest tail risk in the current market, with ongoing concerns about excessive investments in AI projects by tech companies [2]. Group 3: AI Industry Developments - Amid the downturn in tech stocks, significant collaboration emerged in the AI sector. Microsoft, Nvidia, and Anthropic, a major competitor of OpenAI, formed a three-party alliance, with Anthropic planning to invest $30 billion in cloud computing power from Microsoft Azure over the next decade, all supported by Nvidia hardware. In return, Nvidia committed to investing up to $10 billion in Anthropic, while Microsoft pledged up to $5 billion. This collaboration boosted Anthropic's valuation to approximately $350 billion, nearly doubling from $183 billion in September [5]. - This $45 billion partnership creates a unique "symbiotic cycle": Microsoft's investment will flow back through Anthropic's cloud power purchases, while Nvidia solidifies its hardware dominance by binding with an AI leader. Anthropic aims to implement a "dual cloud strategy" to reduce reliance on a single cloud service provider, further diluting OpenAI's industry influence. Market attention is now focused on Nvidia's upcoming Q4 fiscal year 2025 earnings report, which is expected to reshape market expectations for the AI industry, with projected revenues of $39.3 billion (up 78% year-on-year) and data center revenues of $35.6 billion (up 93% year-on-year) [5].
