Golden Butterfly Philosophy
Created by Tyler (PortfolioCharts), the Golden Butterfly evolves the Permanent Portfolio by adding a 20% slice of small-cap value stocks. The five equal slices (total market stocks, small-cap value, long bonds, short bonds, and gold) capture the historical value factor premium while maintaining broad economic resilience across prosperity, deflation, inflation, and recession.
60/40 Philosophy
The 60/40 portfolio is the institutional benchmark: 60% in broad equities and 40% in aggregate bonds. Based on Modern Portfolio Theory, it assumes stocks and bonds are loosely negatively correlated, providing growth during bull markets and cushioning during downturns. Its simplicity and long track record make it the default comparison for all other strategies.
Key Differences Explained
The Golden Butterfly improves on the 60/40 in nearly every dimension: higher CAGR (8.9% vs 8.2%), much lower drawdown (-15.0% vs -20.5%), and significantly better Sharpe ratio (0.68 vs 0.48). The key additions are gold (inflation hedge) and small-cap value (factor premium), which the 60/40 completely lacks.
