When holding the Warren Buffett Portfolio, how long should you stay invested to have high probability to achieve a positive return?
Over the selected period (~154 years), the longest duration with a negative return was 181 months (from September 1929 to September 1944).
This indicates that, within the same timeframe, any rolling period of 182 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
A rolling return is a measure of investment performance that calculates the return of an investment over a set period of time, with the starting date rolling forward. This approach can provide a more accurate representation of the investment's historical performance and helps investors to evaluate the investment's consistency over time.
