When holding the Alpha Architect Robust Portfolio, how long should you stay invested to have high probability to achieve a positive return?
Over the selected period (~44 years), the longest duration with a negative return was 62 months (from January 2004 to February 2009).
This indicates that, within the same timeframe, any rolling period of 63 months or more has consistently resulted in a positive return.
Understanding this metric is crucial as it highlights the importance of a safe investment horizon. Knowing the minimum duration required to likely see positive returns helps investors set realistic expectations and reinforces the strategy of staying invested through market cycles. This approach can mitigate the emotional reactions to short-term market fluctuations and enhance the likelihood of achieving financial goals.

Rolling Returns
