当地时间12月12日的美股市场，注定要被载入近期的波动史册，曾经凭借AI概念一路高歌的科技巨头集体失速，三大指数同步走低，其中纳指创下两周新 低。 这波下跌绝非偶然，背后是市场对AI商业化前景的重新审视，更是多重宏观因素交织的必然结果。 过去一年，绑定OpenAI几乎是美股市场最稳妥的上涨密码，甲骨文曾因与OpenAI的合作单日市值飙升近2500亿美元。 但这种神奇的联动效应，在12月彻底失效，11日暴跌近11%后，甲骨文12日再跌4.5%，两天内市值蒸发规模令人咋舌。 更令人意外的是芯片巨头博通，即便四季度销售额和利润均超预期，且上调了下季度收入预期，股价仍在12日暴跌11.4%，市值蒸发约2200亿美元。 市场情绪的反转，源于对AI业务盈利逻辑的深层担忧，博通CEO透露的两个信息彻底点燃了抛售潮。 当AI概念的光环开始褪色，那些被热捧的巨头为何突然成了市场抛售的对象？ AI业务毛利率低于非AI业务，且与OpenAI的巨额合同在2026年难以贡献显著收益，大部分回报要等到2027年之后。 在资本市场追求短期回报的逻辑下，这种漫长的盈利周期显然难以满足投资者的期待。 更值得关注的是，科技行业的投入产出规律本就 ...

Core Insights - The market is entering an unprecedented "bubble era" characterized by rapid alternation between prosperity and recession, driven by extreme expectations surrounding AI technology [1] - Historical patterns show that major technological leaps have consistently led to large-scale asset bubbles, with the current AI revolution being supported by government initiatives [1][2] - The report indicates that while the market shows typical bubble characteristics by 2025, core U.S. tech stocks have not yet reached extreme instability levels seen during the 1990s internet bubble [1] Government Support and Bubble Dynamics - Historical connections exist between major technological changes and asset bubbles, with past examples including the railway stocks in the 19th century and the tech bubble of the late 1990s [2] - Unlike previous bubbles, the current AI bubble benefits from strong government backing, which provides ample funding and higher policy tolerance, extending the bubble's growth cycle [5] - Geopolitical competition has intensified countries' commitments to AI, further reinforcing the bubble's resilience [5] Market Volatility and Expectations - The current market volatility is attributed to the "expectation gap" surrounding AI technology, where the promise of transformative change contrasts with the slower-than-expected realization of that change [6] - This expectation gap leads to frequent swings in market sentiment between extreme optimism and cautious skepticism [6][7] - The volatility driven by technological expectations is more sudden and rapid compared to traditional market cycles, rendering conventional forecasting models ineffective [7] Bubble Risk Indicators - Bank of America has developed a bubble risk indicator based on four key asset price characteristics: returns, volatility, momentum, and fragility [8] - A notable feature of this indicator is that volatility increases as prices rise, contrary to typical market behavior, indicating potential extreme positions driven by fear of missing out (FOMO) [8] - While the overall U.S. stock market and core tech stocks have not shown typical bubble instability, certain segments are already exhibiting bubble characteristics [11] Unique Risks and Market Concentration - The current AI bubble faces unique risks due to its unprecedented scale, with market concentration at historical highs, exemplified by Nvidia's market cap exceeding that of any European country [20] - If Nvidia were to be valued at the peak P/E ratio of Cisco in 2000, its market cap could reach $20.8 trillion, highlighting the potential for significant market corrections based on forward earnings expectations [22] - Predictions suggest that AI spending could reach $3-4 trillion annually by 2030, with long-term estimates reaching $5 trillion, but there are concerns about the overestimation of AI's productivity potential [22] Investment Strategy Recommendations - The report suggests a counterintuitive investment strategy during bubble periods: diversification may increase risk, while concentrated holdings in leading assets combined with cash hedges are recommended [23] - Historical data indicates that assets at the forefront of bubbles tend to outperform until the bubble bursts, making diversification a risky approach [23] - The report also notes that during previous bubbles, the center of the bubble often outperformed global markets, which may contradict the notion of an impending peak in the "American exceptionalism" theme by 2025 [25] Conclusion on Market Outlook - While timing the market remains challenging, the eventual bursting of the AI bubble appears inevitable, with tightening financial conditions identified as a significant risk factor [27] - High volatility is expected to persist, keeping the market fragile, while ongoing debates about AI's future will continue to elevate uncertainty and instability [27]
