投资人此刻最想问的是，人工智能（AI）究竟是不是泡沫，会不会爆？财经评论员认为，这根本问错 问题，事实上，AI泡沫早已开始泄气了，只是不像当年达康泡沫那样猛烈爆开。 财经评论员杜莫维奇表示，此刻AI泡沫确实存在，但独立研究机构MacroStrategy Partnership估计，AI泡 沫比2000年爆掉的达康泡沫大17倍，绝对是误导人，那项分析衡量的是所有资产类别的总资本配置，并 不是针对AI而已。 更重要的是，众人都问错问题。这场辩论不应是"AI泡沫会不会爆"--事实上早已发生，只是泡沫慢慢泄 气，不像轰然大爆炸那般引人瞩目。然而，一连串慢动作泄气，正悄悄重塑整个AI市场生态。 杜莫维奇指出，伤亡数字正日积月累。2024年，新创公司关门家数暴增；2025年，有95%的企业AI试验 计划未能在推出六个月内，达成可评量的损益（P&L）目标；而且，今年来，募资失败率占所有创业投 资交易比率达到15.9%，是十年来最高。 但相较于2000年达康泡沫爆破，AI泡沫的威胁不是被夸大，就是被误解。AI泡沫并非达康泡沫翻版， 反倒更有趣且获利前景更可观，但必须押对宝。 超大规模云端服务业者（hyperscalers）指 ...

Core Viewpoint - UBS reports that the market is in the early stages of a potential bubble, but key signals indicating a peak—extreme valuations, long-term overheating catalysts, and short-term peak signals—have not yet emerged [1][3][4]. Group 1: Current Market Conditions - UBS identifies that the current U.S. stock market meets all seven prerequisites for a bubble, including a 14% annual outperformance of stocks over bonds in the past decade and significant new technology emergence [5]. - The report emphasizes that the rationale behind the current AI bubble is more robust than that of the 2000 internet bubble, as the key peak events have not yet occurred [3][5]. Group 2: Generative AI Potential - The disruptive potential of generative AI and its unprecedented adoption speed are unique, with OpenAI attracting 800 million users in just three years, compared to Google's 13 years for the same scale [6][7]. - If generative AI can temporarily boost productivity growth by 2%, it could support a 20-25% upside in the stock market [7]. Group 3: Macro Risk Structure - The macro risk structure has fundamentally changed; during the 2000 internet bubble, the U.S. government had a budget surplus, while now the government debt-to-GDP ratio is double that of the past, with high fiscal deficits [8][11]. - This "weak government, strong corporate" dynamic may lead investors to shift funds from nominal assets to real assets, lowering the equity risk premium (ERP) and supporting higher stock valuations [11]. Group 4: Valuation Signals - UBS notes that extreme valuations typically accompany bubble peaks, but current valuations in AI-related sectors are not at dangerous levels [12]. - The absolute valuation levels are still distant from historical peaks, where at least 30% of stocks had P/E ratios soaring to 45-73 times [12]. - The current ERP is around 3%, indicating that the market has not completely ignored risks due to excessive optimism [14]. Group 5: Long-term Catalysts - There are currently no clear long-term structural factors, such as over-investment and excessive leverage, that typically trigger bubble bursts [22]. - ICT investment as a percentage of GDP remains below the peak levels of 2000, suggesting that a capital expenditure frenzy has not yet formed [22][26]. - The risk of excessive debt financing is low, as major tech companies rely on strong cash flows rather than debt for investments [26]. Group 6: Short-term Peak Signals - No short-term peak signals have emerged, such as major merger and acquisition activity comparable to the internet bubble's peak [32][34]. - Current market conditions do not exhibit extreme price momentum, with semiconductor stocks only 35% above their 200-day moving average, compared to 70% at the peak in 2000 [40]. Group 7: Conclusion - UBS provides a detailed "bubble map" for investors, indicating that despite the AI boom, key indicators across valuation, macro catalysts, and short-term triggers suggest that the current market may not be nearing its end [43].
