The Rule of 110 offers a straightforward approach to asset allocation by suggesting that the percentage of a portfolio invested in stocks should be 110 minus the investor's age. This method aims to balance risk and return by adjusting the stock-to-bond ratio as one ages. For instance, a 30-year-old would allocate 80% of their portfolio to stocks and 20% to bonds, reflecting a higher risk tolerance and potential for growth. Conversely, a 65-year-old would have a more conservative allocation, with 45% in stocks and 55% in bonds, prioritizing stability and income. This strategy underscores the importance of adapting investment strategies to align with changing financial goals and risk appetites over time. While the Rule of 110 provides a general guideline, individual circumstances such as financial goals, market conditions, and personal risk tolerance should also be considered when making investment decisions. The visual representation of this rule through donut charts effectively illustrates the shift in asset allocation as one ages, highlighting the dynamic nature of investment planning. This approach encourages investors to periodically review and adjust their portfolios to ensure they remain aligned with their evolving financial objectives and life stages.
