Hu Xiu·2025-12-18 10:30Core Viewpoint - The recent significant decline in the US AI sector stocks, including major players like Oracle, Nvidia, and AMD, indicates a fundamental shift in valuation logic, moving from growth expectations to a focus on return on investment (ROI) [1][11]. Group 1: Market Reaction - The AI sector experienced a collective drop, with Nvidia down 3.81%, AMD down 5.29%, and Oracle down 5.40%, resulting in the loss of hundreds of billions in market value [1][6]. - The catalyst for this decline was the termination of a $10 billion financing deal by Blue Owl Capital with Oracle, raising concerns about Oracle's debt levels and spending [2][3]. Group 2: Systemic Risk - The exit of Blue Owl Capital signifies a crack in the funding chain for AI infrastructure, leading to fears of systemic risk across the industry [4][5]. - The market's reaction suggests that if a major player like Oracle, which has over $500 billion in orders, cannot secure funding for significant projects, it raises alarms about the entire AI infrastructure sector [4]. Group 3: Diverging Institutional Views - Analysts from KeyBanc and Stifel have lowered Oracle's target price due to concerns over its financial health and ability to fulfill its substantial order backlog [7]. - In contrast, Morgan Stanley's Joseph Moore remains bullish on Nvidia, raising its target price, arguing that the market is overreacting to competitive threats [9]. Group 4: Valuation and ROI Focus - The focus of investment has shifted from capital expenditure to ROI, with firms like Wellington Management emphasizing the need for sustainable returns to justify AI investments [11]. - Current estimates suggest that the AI industry must generate approximately $600 billion in annual revenue to validate the significant investments being made, while actual revenue projections for 2025 are much lower, around $150 billion to $200 billion [12][13]. Group 5: Impact on A-shares - The decline in US AI stocks has also affected related A-share companies, with significant drops observed in stocks like Zhongji Xuchuang and Xinyi Sheng [14].
