Core Viewpoint - The current market environment, characterized by soaring stock prices of tech giants like Nvidia and Microsoft amid the AI wave, raises concerns reminiscent of the "irrational exuberance" warning from former Fed Chairman Alan Greenspan in 1996, with financial leaders warning of significant market correction risks in the next six months to two years [1] Valuation Metrics - The S&P 500's price-to-earnings (P/E) ratio is approximately 23 times, nearing a five-year high and significantly above the ten-year average of 18.7 times, yet still below the peak of around 25 times during the dot-com bubble of 1999-2000 [1] - The tech sector's P/E ratio stands at about 30 times, exceeding the long-term average of 21.4 times, but remains far from the extraordinary level of 48 times seen during the dot-com bubble [1] Market Sentiment - The trading volume of stock options, a measure of bullish sentiment, is approaching a four-year high, heavily concentrated in AI-related tech stocks, indicating strong market enthusiasm for tech stock gains [1] Analyst Perspectives - Despite market concerns, many analysts and investors believe the current situation differs from 2000, with Goldman Sachs analysts asserting that the current rally is driven by "fundamental growth rather than irrational speculation," highlighting that leaders in the AI field are established companies like Microsoft and Google with solid business models and substantial profits, unlike many unprofitable startups of the past [1] Investor Positioning - Data shows that institutional investors are maintaining a neutral position, while retail investors are allocating more funds to bonds and money markets, indicating a lack of extreme enthusiasm in the market [1]

智通财经APP获悉，近期，美联储主席再次提及美国股市估值过高的问题，但市场却依旧置若罔闻。 历史经验表明，这种态度或许不无道理：过去的历次警告不仅从未引发即时回调，反而往往对应着行情 上扬期——至少在短期内如此。 摩根大通的数据显示，自1996年以来，在历任联储主席发出估值警告后，标普500指数未来12个月平均 涨幅接近13%。该行同时指出，这些预警后的一年期内，美股表现通常领先全球市场。 本次鲍威尔上周声称"股票估值偏高"之际，恰逢众多策略师逐渐形成共识：估值攀升正成为华尔街新常 态。他们认为，科技行业推动的盈利增长势头，理应支撑更高的估值倍数。 Miller Tabak + Co LLC首席市场策略师Matt Maley在谈及鲍威尔对估值的评价时表示："毫无疑问，市场 对此不为所动。"自鲍威尔发表相关言论以来，标普500指数整体持平。 Yardeni Research Inc.总裁兼首席投资策略师Ed Yardeni表示，鲍威尔的言论加剧了他对市场持续上涨的 担忧。尽管Yardeni仍维持标普500指数今年达到6800点的目标，但他也指出，该指数目前的市盈率已接 近历史高点，市销率更是创下历史新高。 尽管 ...

美联储主席对股市估值的警告历来备受市场关注，但据摩根大通最新研究显示，此类警示对市场的实际影响往往有限。 鲍威尔本周在讲话中明确表示，尽管股票价格"估值相当高"，但这并非金融稳定风险升高的时期。他强调，进一步政策正常化的路径并非毫无风险。这一表 态延续了美联储主席对资产价格估值发出警示的传统。 据追风交易台，摩根大通分析显示，从1996年格林斯潘的"非理性繁荣"到本周鲍威尔表示股价"估值相当高"，美联储主席的估值担忧并未引发显著市场调 整。 据摩根大通，自1996年以来的历次美联储主席估值警告后，标普500指数在随后1个月、6个月和12个月内均未出现负收益。平均而言，警告后12个月的正收 益仅略低于警告前6个月的表现，市场增长放缓但仍保持上涨趋势。 历史上的美联储主席估值警告 摩根大通梳理了自1996年12月格林斯潘警告"非理性繁荣不当推高资产价值"以来的历次美联储主席估值警告。这些警告涵盖了不同的宏观经济环境，但大多 数发生在宽松货币政策时期。 伯南克曾在2013年5月警告过度风险承担，耶伦在2014年7月和2015年5月分别对特定行业和整体市场的高估值表达担忧。鲍威尔在疫情期间曾以相对术语讨 论估值问题， ...

Core Viewpoint - Federal Reserve Chairman Jerome Powell stated that the stock market is "fairly valued," which has caused significant reactions in the stock market [2] - Concerns about the sustainability of AI trading have also been attributed to the market's weakness [2] Valuation Metrics - The CAPE ratio, designed by economist Robert Shiller, has been rising since the bull market began, reaching just below 38 at the end of August, a level not seen since the end of 2021 [4] - The CAPE ratio is calculated by dividing the S&P 500 index level by the inflation-adjusted average earnings of its constituent companies over the past ten years [4] - The S&P 500's CAPE ratio has reportedly surpassed 40 for the first time since 2000, indicating a potential market peak [4] Buffett Indicator - The "Buffett Indicator," which compares the total market value of U.S. stocks to the GDP, shows that the stock market's total value was approximately $64.5 trillion as of June, while the GDP was $23.7 trillion, resulting in a valuation of about 2.7 times GDP, the highest since March 2001 [7][8] - Analysts view this indicator as a useful measure of stock valuation, as it reflects the relationship between asset prices and economic activity [7][8] Price-to-Sales Ratio - The price-to-sales ratio for the S&P 500 reached 3.12 at the end of August, the highest level since January 2000, indicating that the index is more expensive relative to its expected sales [11] - Some analysts consider the price-to-sales ratio a more realistic measure of stock market valuation compared to net income figures, which can be manipulated [11] New Normal - Recent earnings expectations have been rising rapidly, suggesting that corporate profits may reach new historical highs in Q3, which could lead investors to accept higher valuations [14] - Analysts suggest that high valuations may represent a "new normal," as the largest U.S. companies today differ significantly from those in the 1980s and 1990s, with lower debt-to-equity ratios and reduced volatility in earnings [14]

盈利增长能否化解潜在危机。 受美联储降息预期提振，美国三大股指本周一连续第二个交易日联袂创历史新高。然而，市场情绪在美 联储主席鲍威尔有关估值问题的表态后有所降温，股市连续两个交易日回落。 1996年12月5日，格林斯潘在一次演讲中表示："我们如何知道非理性繁荣何时会过度推高资产价值，进 而导致资产价值遭受意外且持续的下跌？""非理性繁荣" 这一说法因格林斯潘而广为人知，后来更成为 互联网泡沫的代名词。在他发表这番演讲三年多后，股市才达到当时的峰值。当前这轮牛市是否会面临 类似结局，仍有待观察。不过从以下三个指标看，潜在风险似乎值得注意。 周期调整市盈率 周期调整市盈率（CAPE）由诺贝尔经济学奖获得者、耶鲁大学经济学家罗伯特·席勒于1988年提出，其 核心逻辑是通过计算股价与过去10年经通胀调整的平均盈利之比，消除经济周期对短期盈利的干扰，提 供更稳定的估值参考。 自本轮牛市启动以来，该比率持续走高。截至8月底，CAPE 比率已经升至2021年底以来新高。当时美 股开启了一段熊市行情，随着美联储开启紧缩周期，标普500指数在9个月时间内一度下跌超过20%。 希勒团队的网站每月仅更新一次标普500指数CAPE ...

[ 更新后的框架还对最大就业率的潜在不足进行了类似调整，并重申2%的通胀目标设定"最符合双重任 务目标"。 ] 他阐述了美联储决策的复杂性，指出了两个基本问题——各类影响"遵从任务授权"的因素，以及塑造美 联储实现这些目标之程序的考虑因素。 这一双重任务授权——物价稳定和充分就业——会让央行左右为难。鲍威尔有条不紊地阐述了目前影响 这两方面的因素，从关税和移民政策（同时影响供应和需求）到近期就业和GDP增长失去动力的根本原 因。鲍威尔对失业率目前仍然较低的状况甚感欣慰，但强调了劳动力市场中的"奇异平衡"状况——这在 美联储的话里就是"有危险"的意思，因为它可能很快被更高的失业率所取代。我认为这是评估风险平衡 变化的一个关键因素，也将指导未来的政策行动。 鲍威尔对各类政策框架考虑因素的讨论更偏学术性，相较于各个劳动力市场变化考虑因素来说跟利率制 定的直接相关性较低。但这正是一个独立的美联储可以行使最大自由裁量权的领域。 与传统认知相反，中央银行并不制定自身任务。这直接来自国会的授权——最初是1946年颁布的《就业 法案》，随后1978年出台的所谓《汉弗莱-霍金斯法案》又增加了控制通胀的内容。虽然美联储有权去 对 ...
