This combination of "high valuation + extreme concentration" is similar to previous crashes in 1929 and 2000. The greater risk lies in the surge in AI capital expenditures; however, despite the rampant bubble theories, the market has not yet shown signs of extreme irrational exuberance Despite Goldman Sachs maintaining its optimistic forecast that the U.S. stock market will continue to rise to 7,600 points by 2026 in its latest outlook, its strategists have also issued a stern warning, pointing out that the current valuation and concentration structure of the U.S. stock market resembles characteristics seen before several major crashes in the past century. On Wednesday, January 7, Goldman Sachs' newly appointed Chief U.S. Equity Strategist Ben Snider released his 2026 outlook report. In the report, he predicts that driven by U.S. economic growth and the Federal Reserve's continued accommodative policies, the S&P 500 index will achieve a total return of 12% by 2026, with a year-end target price of 7,600 points. Snider noted that of the 16% price return of the S&P 500 index in 2025, earnings growth contributed 14%. He expects that with productivity improvements brought about by AI adoption, the S&P 500's earnings per share (EPS) will grow by 12% in 2026 and 10% in 2027, providing a fundamental basis for a sustained bull market. However, behind this seemingly optimistic report, Goldman Sachs elaborated on the structural vulnerabilities facing the market. ## Valuation and Concentration Approaching Historical Extremes, Market Vulnerability Rising Goldman Sachs strategists warned that the core tension in the U.S. stock market lies in the contradiction between a "solid fundamental backdrop" and "valuation multiples near historical highs." - **High Valuation:** Currently, the forward price-to-earnings (P/E) ratio of the S&P 500 index based on expected earnings per share for the next 12 months is as high as 22 times. This level is on par with the peak in 2021 and is just a step away from the historical record of 24 times during the 2000 internet bubble. Snider acknowledged that such a high multiple increases the magnitude of market declines if earnings fall short of expectations. - **Extreme Concentration:** The top ten stocks in the S&P 500 index currently account for 41% of the market capitalization and 32% of the earnings. In 2025, these leading stocks contributed 53% of the index's returns. Goldman Sachs pointed out that as concentration rises, the embedded idiosyncratic risks in the S&P 500 index and investors' reliance on the continued strength of a few largest companies also increase. Snider used physics terminology to describe the current situation: "Valuation and concentration are measures of 'potential energy' that require a catalyst to convert into 'kinetic energy' (i.e., a decline) in the stock market." He emphasized that the current combination of "high valuations, extreme concentration, and recent strong returns" in the U.S. stock market is similar to several overheated market conditions seen in the last century. These characteristics appeared to varying degrees in the **market boom of the 1920s, the 'Nifty Fifty' dominance in the early 1970s, the bull market before Black Monday in 1987, and the markets of 2000 and 2021**. A common point among these historical periods is that they all ultimately ended with "significant declines in the stock market." Goldman Sachs explicitly warned that the current market faces the risk of experiencing similar pullbacks, which is the focal point of the current debate about whether there is a "bubble." ## Capital Flows Have Not Gone Crazy, Bonds and Money Market Funds More Favored Despite concerns about market structure, Goldman Sachs also pointed out a key difference between the current market and past bubble periods: investor sentiment and capital flows have not yet reached extreme levels of euphoria. - **Speculative Activity:** Although speculative trading activity is sharply rising in 2025, it remains well below the peaks of 2000 or 2021. - **Capital Flows:** Last year, U.S. stock ETFs and mutual funds saw an inflow of about $100 billion, accounting for only 0.2% of the S&P 500 market capitalization, placing it in the 45th percentile over the past 20 years. - **Risk Aversion:** In contrast, U.S. bond funds attracted about $700 billion in inflows, while money market assets grew by over $900 billion. Goldman Sachs' Snider believes that this relatively restrained capital flow indicates that, despite the market being at historical highs and frequent discussions of bubble risks, there has not been an extreme irrational exuberance. ## Surge in AI Capital Expenditure Faces Huge Profit Return Challenges Ahead Setting aside macro factors, Goldman Sachs believes the current key micro risk lies in the trajectory of AI capital expenditure (Capex) and its return rates. - **Spending Surge:** In 2025, the total capital expenditure of the largest publicly traded hyperscale tech companies is expected to be around $400 billion, an increase of nearly 70% from 2024 and 150% higher than spending levels before the release of ChatGPT in 2022. - **Debt Dependency:** AI investments are expected to continue growing this year, with capital expenditure likely reaching 75% of cash flow—similar to the tech spending levels of the late 1990s. Future spending growth will increasingly rely on debt financing. - **Profit Gap:** Over the past decade, the profits of these large tech companies have typically been 2-3 times their past capital expenditures. Given the market's general expectation of an average annual capital expenditure of $500 billion from 2025 to 2027, these companies would need to achieve an annual profit run rate of over $1 trillion to maintain the capital return rates that investors are accustomed to. However, the current profit expectations for 2026 are generally only $450 billion. Nonetheless, Snider remains optimistic at the end of the report, writing: > Investors entering 2026 can expect substantial beta and alpha returns. For index investors, lower implied volatility and smaller credit spreads provide tools to maintain exposure to stock upside while controlling downside risk. Within the stock market, the dynamic macro environment, significant valuation disparities, and lower correlations create abundant opportunities for stock pickers ### Related Stocks - [.SPX.US - S&P 500](https://longbridge.com/en/quote/.SPX.US.md) ## Related News & Research | Title | Description | URL | |-------|-------------|-----| | 一文读懂 2026 年至今的全球市场:什么在涨?美股为何不行?这种趋势会持续吗? | 高盛报告揭示 2026 年市场新风向:周期性资产上涨仍有空间;但 AI 等热门主题估值过高,高波动或成为未来常态;美元将持续疲软;建议警惕高估值板块,分散股票持仓、保持健康的非美敞口(包括新兴市场),以及较长期限指数波动率的做多头寸。 | [Link](https://longbridge.com/en/news/276406606.md) | | 美股的 “危险信号” | 本月标普 500 指数成分股在八个交易日内下跌 7% 或以上的股票数量已经超过 100 只,直逼 2022 年美股熊市的水平。 虽然这不像新冠疫情或关税危机期间那样极端,但该指标超过 100 通常意味着更大范围的下滑,而这种情况目前还没有发 | [Link](https://longbridge.com/en/news/276185288.md) | | 高盛推出 “抗 AI 冲击” 主题投资组合:做多算力与安全,做空可被替代的软件股 | 高盛推出一项新的软件股多空组合,做多那些业务难以被人工智能取代、或直接受益于 AI 需求增长的公司,同时做空可能被自动化或被企业内部替代的软件企业。此前随着 Anthropic 等公司推出面向法务和税务的 AI 工具,引发相关软件股大幅下跌 | [Link](https://longbridge.com/en/news/275943203.md) | | 特朗普暗示违法征收的关税不退了,美财长称今年关税收入将 “基本保持不变” | 美国总统特朗普暗示不会退还被最高法院裁定违法的关税,预计 2026 年关税收入将保持不变。特朗普计划签署行政令,对全球商品加征 10% 进口关税,取代被推翻的关税。财长贝森特表示,政府将利用替代法律权力维持关税收入,强调国家安全和财政收入不 | [Link](https://longbridge.com/en/news/276494362.md) | | 美财政部让步,拟修订主权财富基金税收提案,此前遭私募业警告 | 美国财政部正就一项针对主权财富基金和公共养老基金征税方式进行全面改革的提案作出让步。相关提案此前由美国国税局提出,拟更新税法第 892 条,将这些基金持有的多数美国债务投资归为商业活动,这将令其面临被征税的风险。此前,私募信贷和私募股权公司 | [Link](https://longbridge.com/en/news/276491732.md) | --- > **Disclaimer**: This article is for reference only and does not constitute any investment advice.
