Challenging Life Cycle Investing Tenets
The podcast episode discusses a recent study that challenges two central tenets of life cycle investing. The authors argue that investors should be 100% invested in stocks rather than diversifying across stocks and bonds. Furthermore, they argue that this approach should be maintained even during retirement. The study finds that an even mix of 50% domestic stocks and 50% international stocks outperforms age-based stock strategies in building wealth, supporting retirement consumption, preserving capital, and generating bequest.
The Impact of Data Source on Investment Advice
The podcast explains the limitations of using US stock data as the basis for investment advice. The sample size of major asset classes in the US is relatively small, and survivorship bias may affect the findings. The study addresses this issue by using a database that includes 38 developed market countries from 1890 to 2019, providing a more comprehensive and diverse dataset. This enables a more accurate assessment of investment strategies and retirement spending rates. The study reveals that a 100% stock portfolio, including 50% domestic and 50% international stocks, produces higher average retirement wealth and reduces the probability of retirement ruin compared to traditional strategies.
Considerations and Behavioral Challenges
The podcast highlights some behavioral challenges and considerations that individuals should be aware of when considering a 100% stock portfolio. While the study supports the benefits of this approach, it acknowledges the increased volatility and potential for larger drawdowns. The podcast emphasizes the importance of investor behavior and the ability to stay invested during market downturns. It also cautions that individual circumstances and risk tolerance should be taken into account, as not all investors may have the fortitude to withstand significant market fluctuations. The podcast concludes by encouraging investors to carefully consider the findings and their own risk tolerance before making investment decisions.
