曾因押注美国次贷危机而名声大噪的《大空头》原型人物、投资人迈克尔·伯里(Michael Burry)，近日再度掀起波澜，将火力对准了美股最 炙手可热的人工智能(AI)赛道。 他指责美国几家最大的科技公司通过激进的会计操作，在AI热潮中"虚增"盈利。 与此同时，华尔街大型投 行高管及知名做空者频频发出警告，认为美股可能出现回调。 伯里当地时间周一在社交平台X上发文称，那些所谓的"超大规模算力服务商"，正在通过延长芯片折旧年限、压低折旧费用，人为放大AI热 潮带来的账面利润。 周一，英伟达股价在上周下跌7%后反弹近6%；Palantir则在上周大跌11%后回升约9%。不过，英伟达和Palantir周二股价再度走低。 伯里最后还表示，他将在11月25日公布更多细节，并让关注者拭目以待。 与此同时，日本软银集团作出了一项令人意外的举动：清仓了"AI芯片霸主"英伟达股份，套现58亿美元，加剧了外界对AI热潮或已触顶的担 忧。 他写道： "通过延长资产的使用年限来低估折旧支出，从而虚增利润，是现代财报中最常见的把戏之一。在以英伟达芯片和服务器为代表、 产品周期仅两三年的情况下，大规模增加资本开支并不应成为企业延长计算设备 ...

Group 1: Market Analysis - Xia Junjie highlights that the current market, particularly driven by AI, exhibits characteristics similar to historical bubbles, such as the 1999 internet bubble and the 2021 new energy boom, in terms of market capitalization, DCF valuation, cumulative gains, and capital participation [4]. - He emphasizes that the emotional highs and lows experienced in the market are likely a result of being in a bubble, reflecting collective psychology and expectations [4][5].

The MAG7 companies (Apple, Microsoft, Amazon, Google, Meta, Tesla, Nvidia) account for over 30% of the S&P 500's total market capitalization and contributed 48% of the market expansion since 2023 [1][6][7]. - There are concerns about a potential tech bubble, as the current market concentration resembles the tech bubble of 2000. The price-to-earnings (PE) ratio is nearing its highest level since 1990, and the leverage ratio in the market has increased to 1.7%, surpassing the 1.5% level seen during the 2000 internet bubble [2][3][23]. - The K-shaped economic recovery is evident, with high-income households seeing a net worth share of 63.0% by Q2 2025, up 1.5 percentage points from Q4 2022. Meanwhile, traditional sectors have not fully recovered to pre-pandemic trends [7][8]. Group 2 - The Federal Reserve is expected to continue its accommodative monetary policy into the first half of 2026, with interest rates potentially dropping to the 3.00-3.25% range. However, the scope for further easing is limited, and historical trends suggest that the S&P 500 typically performs poorly in the months leading up to the end of a rate-cutting cycle [2][29]. - Capital expenditures (CAPEX) for MAG7 companies are projected to slow significantly, from a growth rate of 48.8% in 2025 to 18.8% in 2026, and further down to 6.0% in 2027.

Core Viewpoint - The Federal Reserve has lowered the benchmark interest rate by 25 basis points to a target range of 3.75-4.00%, with plans to stop balance sheet reduction on December 1 and gradually replace maturing agency debt with short-term Treasury bonds. The Fed believes inflation, employment, and financial stability remain controllable, but there are significant internal disagreements regarding future rate cuts [1][5]. Economic Summary - The Fed continues to assess the coexistence of inflationary and employment risks, noting that both "dual risks" are easing. While inflation has upward risks, the overall trend remains manageable. The analysis indicates that commodity inflation is supported by tariffs but is likely one-time, housing service inflation is expected to decline, and other service inflation pressures are weak due to a soft labor market [3][4]. - Employment risks are present but marginal changes may have stabilized. Despite data gaps from government shutdowns, state-level unemployment claims and job vacancies provide decision-making references, showing stable employment conditions over the past month [3]. Policy Summary - The Fed has cut rates by 25 basis points to a range of 3.75-4.0%. There is increasing disagreement among committee members regarding future rate cuts, with some suggesting a pause to observe conditions. Powell likened the current situation to "driving in fog," suggesting a cautious approach [5]. - The Fed will stop balance sheet reduction on December 1, replacing maturing mortgage-backed securities with short-term Treasury bonds. Current bank reserves are nearing acceptable levels, and signs of tightening liquidity in the money market have emerged [5]. Forward-Looking Summary - The Fed's rate-cutting cycle is entering a phase of increased disagreement. In the short term, due to potential government shutdown impacts, a rate cut in December is likely. In the medium term, the policy rate may approach 3% by 2026, with expectations of 3-4 rate cuts before the end of 2026 [6]. - The ongoing investment wave in artificial intelligence and the K-shaped economic recovery are expected to continue, with inflation and employment risks remaining manageable for the foreseeable future [6]. Strategy Summary - Market expectations for rate cuts have shifted, with pricing for a December cut dropping from 23 basis points to 17 basis points, leading to a hawkish market sentiment. U.S. Treasury yields have risen across the board, with the 2-year yield up by 10.8 basis points to 3.60% and the 10-year yield up by 10.0 basis points to 4.098% [7][8]. - The U.S. dollar has strengthened slightly, with the dollar index rising by 0.56% to 99.22. The stock market remains stable, with mixed performances among major indices [8]. - In the medium to long term, the U.S. stock market may face increased volatility, transitioning from a phase driven by valuation and earnings to one driven by earnings growth amid heightened market fluctuations [8].
