2026年卸任前，鲍威尔留给华尔街的一句话：美股价格已很昂贵

Core Viewpoint - The stock market has shown significant gains in 2025, with the Dow Jones Industrial Average, S&P 500, and Nasdaq Composite rising by 15%, 18%, and 22% respectively as of December 24. However, not all analysts share this optimism, particularly Federal Reserve Chairman Jerome Powell, who has highlighted the risks associated with high stock valuations [1][2]. Group 1: Stock Market Performance - As of December 24, 2025, the Dow Jones Industrial Average, S&P 500, and Nasdaq Composite have increased by 15%, 18%, and 22% respectively [1]. - Powell's comments suggest that the Federal Reserve is aware of the potential impact of stock market valuations on monetary policy [2]. Group 2: Valuation Concerns - Powell indicated that stock prices are at "quite high valuation levels," referencing the Shiller P/E ratio, which has reached 40.74, nearing historical highs [2][5]. - The Shiller P/E ratio has an average of 17.32 over 155 years, and the current level is close to the peak of 41.20 during the recent bull market and the 44.19 peak before the 1999 internet bubble [5]. Group 3: Historical Context - Historical data shows that the Shiller P/E ratio exceeding 30 has only occurred six times in 155 years, with subsequent declines in major indices ranging from 20% to 89% [5]. - The average bear market since 1929 lasts about 286 days, while bull markets average 1,011 days, indicating that markets spend more time in an upward trend [11].
