德银200年数据验证：在低估时买入，长期回报更高

Core Viewpoint - The article discusses a report by Deutsche Bank that analyzes long-term asset returns across various economies, revealing key variables that predict future returns and providing a historical basis for strategic asset allocation [4]. Group 1: Long-Term Asset Performance - Over the past 200 years, stocks have provided a median annualized return of 4.9%, outperforming traditional 60/40 stock-bond portfolios at 4.2%, government bonds at 2.6%, and gold at 0.4% [7]. - Since 2000, gold has achieved an annualized real return of 7.45%, surpassing stock returns in the U.S. (5.8%), Germany (3.9%), and the UK (3.3%), highlighting the variability of asset performance across different time periods [8]. - Stability is crucial for long-term returns, with Sweden and Denmark being the best-performing markets for stocks and bonds, respectively, while Italy has historically underperformed due to political instability and high debt [8]. Group 2: Importance of Valuation - The report emphasizes that starting valuation is the strongest predictor of long-term returns, with lower valuations leading to higher future returns [9]. - A model dividing economies by valuation shows that low P/E ratio portfolios achieved a 20.2% annualized return over 70 years, compared to 11.4% for high P/E portfolios [11]. - Current high valuations in the U.S. stock market and low dividend yields suggest that investors should lower their return expectations [11][18]. Group 3: Bond Market Insights - For bonds, starting yield is critical; when the yield on 10-year government bonds is below 3%, future real returns are often negative [13]. - The average equity risk premium across 22 countries is 3.2%, but there are significant differences, indicating that stocks do not always outperform bonds [14]. Group 4: Macroeconomic Trends - Global population growth is at its lowest in two centuries, with many economies expected to see a decline in working-age populations by 2050, which could pressure long-term asset returns [16]. - High government debt levels are associated with low real bond returns, posing challenges for future bond investors [16]. Group 5: Investment Strategy - The article concludes that successful long-term investing involves understanding historical patterns, respecting valuation principles, and constructing resilient asset portfolios in an uncertain future [19].
