Permanent portfolio
A permanent portfolio is an all-weather asset-allocation strategy created by investor Harry Browne, dividing assets equally (25% each) among four components: equities (stocks), long-term bonds, short-term bonds (cash), and gold. The design hedges against all major economic scenarios: inflation, deflation, growth, and stagnation.
For simpler all-weather approaches, see all-weather portfolio. For index-based approaches, see three-fund portfolio. For asset-allocation context, see asset allocation.
The four components
- Equities (25%). Stocks for growth and inflation protection.
- Long-term bonds (25%). 20–30 year government bonds for deflation and falling-rate scenarios.
- Short-term bonds (25%). Cash and very short-term bonds for liquidity and safety.
- Gold (25%). For extreme inflation or currency-debasement scenarios.
Each component performs well in certain economic regimes and poorly in others. The equal weighting ensures no single component dominates, and the portfolio as a whole performs acceptably in all conditions.
Economic hedging
- Growth + inflation: Stocks and gold rally; bonds weak. Portfolio gains 10–15%.
- Growth + deflation: Stocks and long bonds rally; gold weak. Portfolio gains 10–15%.
- Stagnation + inflation: Gold rallies; stocks and bonds weak. Portfolio gains 5–10%.
- Stagnation + deflation: Long bonds rally; stocks and gold weak. Portfolio gains 5–10%.
In no scenario does the portfolio crash 30–50% like a traditional stock-heavy portfolio.
Advantages
- Simplicity. Four equal allocations; no complex optimization.
- Stability. Historical maximum drawdowns ~15–20%, far lower than 50% for diversified stocks.
- No prediction required. You do not need to forecast which economic scenario will occur.
- Psychological comfort. Steady, predictable returns with minimal volatility suit risk-averse investors.
Disadvantages
- Moderate returns. Expected returns historically ~6–7% annually, lower than 100% stocks (9%+).
- Gold drag. Gold often underperforms, especially during deflationary or low-inflation periods.
- Opportunity cost. During long bull markets (2010–2020), the permanent portfolio drastically underperformed pure stocks.
- Complexity relative to three-fund. More components than a three-fund portfolio, though still simple.
Rebalancing discipline
The permanent portfolio requires annual rebalancing to maintain 25% in each component. As allocations drift (stocks up to 35%, gold down to 15%), rebalancing forces selling the outperformer and buying the underperformer — enforcing buy-low-sell-high discipline.
