1. Report Industry Investment Rating - Not provided in the report 2. Core View of the Report - The market is expected to maintain a short - term volatile pattern. Although the economic fundamentals show structural improvement, the short - term repair market is insufficient to boost market confidence.

Investors should be patient and wait for clearer market signals [34]. 3.

Core Viewpoint - The article analyzes the current state of the U.S. stock market from a valuation perspective, focusing on three key valuation indicators: Equity Risk Premium (ERP), Shiller CAPE, and Buffett Indicator, highlighting that all three suggest the market is currently overvalued and future returns may be lower than in recent years, while also noting that these indicators do not predict short-term market movements [4][19]. Group 1: Equity Risk Premium - Equity Risk Premium (ERP) measures the attractiveness of stocks relative to risk-free assets, calculated as the S&P 500 dividend yield minus the yield on 10-year U.S. Treasury bonds [8]. - Historical data shows that during periods of high market valuations and low dividend yields, such as the 2000 internet bubble and the recent period, ERP often turns negative, indicating that Treasury investments are more attractive [9]. - Conversely, after significant market downturns, like the 2008-2009 financial crisis, ERP can rebound, suggesting that stocks become more appealing compared to Treasuries [9][10]. Group 2: Shiller CAPE - Shiller CAPE, developed by economist Robert Shiller, assesses market valuation by using the inflation-adjusted average earnings over the past ten years, providing a smoother and more stable measure [13]. - The Shiller CAPE has shown three significant peaks in the last 40 years: during the 1999-2000 internet bubble, before the 2007 financial crisis, and in the current post-pandemic period, with the latest peak approaching historical highs [13][14]. - While Shiller CAPE can illustrate market conditions over long cycles, it does not predict short-term price movements, and high valuations do not necessarily lead to immediate declines [14]. Group 3: Buffett Indicator - The Buffett Indicator compares the total market capitalization of publicly traded companies to the country's GDP, indicating whether the market is overvalued or undervalued [17]. - Since 1980, this ratio has significantly increased, with the market capitalization reaching over 200% of GDP in recent years, surpassing levels seen during the 2000 internet bubble [18]. - Although the Buffett Indicator does not specify when the market will peak or decline, it suggests that when market capitalization is significantly higher than economic output, future long-term returns are likely to be lower [19].
