Adaptive Philosophy
The Adaptive Allocation strategy dynamically adjusts weights across multiple asset classes based on recent momentum and volatility. Unlike fixed-weight portfolios, it increases allocation to trending assets while reducing exposure to volatile or weakening ones. This creates a continuously evolving portfolio that adapts to changing market conditions.
Permanent Portfolio Philosophy
Harry Browne's Permanent Portfolio splits capital equally (25% each) among stocks, long-term government bonds, gold, and cash (T-Bills). Each asset class is designed to thrive in one of four economic states: prosperity, deflation, inflation, and recession. The quarterly rebalancing to equal weights captures mean-reversion gains across these structural allocations.
Key Differences Explained
This pairing shows the tradeoff between sophisticated tactical management and ultra-simple structural defense. The Adaptive strategy nearly doubles the PP's returns (11.5% vs 6.8%) while still maintaining lower drawdowns (-15.3% vs -10.5%). However, the PP requires virtually zero maintenance.
- Strategy Type: Adaptive is a tactical, actively-managed approach. Permanent Portfolio is a passive, buy-and-hold approach.
- Return vs Risk: Adaptive delivered 11.5% CAGR with -15.3% max drawdown (Sharpe: 0.78). Permanent Portfolio delivered 6.8% CAGR with -10.5% max drawdown (Sharpe: 0.58).
- Maintenance: Adaptive requires monthly signal monitoring. Permanent Portfolio needs only annual rebalancing.
