Can You Trust the Market? Equal-Weighted S&P 500 vs. Four-Fund Strategy
Description
In this week’s episode, Paul Merriman shares lessons from a lifetime of investing—prompted by conversations with students, longtime collaborator Rich Buck, and questions from new investors about trust and risk.
Paul dives deep into the data behind his favorite long-term strategies, including the equal-weighted S&P 500 and the classic Four-Fund Portfolio, comparing 25-year results across multiple time periods.
He explains why no one can predict short-term returns, but how history can still guide your long-term strategy. Using decades of data, Paul shows how diversification across size and value has rewarded disciplined investors—even when recent performance has lagged.
