In the landscape of investment, reliance solely on average returns may restrict potential gains for investors. While it is tempting to select the asset class with the highest average return over long periods, making investment decisions based solely on these averages can overlook significant opportunities. Investors who are able to recognize and react effectively to deviations from these averages can benefit greatly.

The article discusses the importance of actively managing investments rather than passively accepting average returns. It posits that investors with a consistent surplus of funds should be strategic in their allocations, considering not just the average performance of asset classes over the last century but also the potential variability and the chances for opportunism. This approach encourages a more nuanced understanding of the financial markets based on complete data.

Furthermore, the commentary on deviations from the average stresses that market fluctuations and trends can present unique prospects that are beneficial for judicious investors. Hence, rather than sticking strictly to the average, embracing variability and being proactive in response to market changes can lead to enhanced investment outcomes.
