The AI Trading Collapse: Unpacking the Broadcom and Oracle Plunge
The U.S. stock market delivered a jarring reminder of the fragility of investor sentiment towards artificial intelligence. On December 12, a pronounced AI sector sell-off gripped traders, with major tech names leading the decline. This wasn’t a broad-based market crash but a targeted retreat from one of the most lucrative—and speculative—trades of the past year.
Broadcom’s Earnings Disappointment: Guidance Trumps Performance
芯片制造商博通 (Broadcom), a critical supplier of custom AI accelerator chips for giants like 谷歌 (Google) and OpenAI, reported impressive fiscal fourth-quarter results. Revenue reached $18.02 billion, beating analyst estimates, with full-year sales hitting $63.9 billion. However, the market’s reaction was brutally negative, with shares tumbling approximately 10%. The core issue emerged during the earnings call with CEO Hock Tan (陈福阳). He revealed that the company’s rapidly growing AI revenue carries lower gross margins compared to its non-AI segments. Furthermore, while Broadcom disclosed a massive $73 billion AI product backlog to be delivered over six quarters, this figure failed to meet the stratospheric expectations baked into the stock price. This AI sector sell-off highlights how even stellar fundamentals can be overshadowed by forward-looking concerns about profitability and growth sustainability.
Fermi’s Setback: A Warning Sign for AI Infrastructure
Market Rotation in Full Swing: From the ‘Magnificent Seven’ to Broader ValueWhile the AI sector sell-off dominated headlines, a more profound shift was underway beneath the surface. Money flowed out of technology growth stocks and into more cyclical and value-oriented sectors. This rotation is a classic sign of a maturing bull market, where leadership begins to broaden.

This environment demands agility and perspective from investors worldwide.
The key takeaway is that the AI revolution remains a powerful long-term trend, but its market manifestation will be punctuated by volatility and periodic reassessments of value. The current AI sector sell-off is a healthy market mechanism, shaking out excesses and redirecting capital to other areas of the economy. For professionals engaged in Chinese equities, this period emphasizes the importance of fundamental analysis, sector diversification, and a global macro lens.
Moving forward, investors should use this turbulence to conduct thorough portfolio reviews. Look beyond headline indices to underlying sector performance. Stay informed on central bank communications from both the 美联储 (Federal Reserve) and 中国人民银行 (People’s Bank of China). Most importantly, recognize that sustainable investing in growth themes like AI requires patience and a tolerance for cyclical downturns. The AI sector sell-off today may well create the entry points for tomorrow’s winners. Take this moment to refine your strategy, ensure your holdings are aligned with a balanced risk profile, and prepare to navigate the next phase of this dynamic market cycle.
