How to Build an All-Weather Portfolio: Asset Allocation and Rebalancing Rules

Ray Dalio’s Bridgewater Associates popularized the concept of the “All-Weather” portfolio—an investment architecture structured to perform reliably across all four economic regimes: high inflation, low inflation, rising growth, and contracting growth.

The Four Economic Quadrants

1. Rising Growth: Favorable for equities, corporate credit, and high-yield instruments.
2. Falling Growth: Favorable for sovereign treasuries, investment-grade bonds, and defensive cash reserves.
3. Rising Inflation: Favorable for commodities, energy assets, TIPS, and physical real estate.
4. Falling Inflation: Favorable for high-duration fixed income and high-multiple growth equities.

Disciplined Periodic Rebalancing

A portfolio that is never rebalanced will inevitably drift into excessive risk concentrations following multi-year bull runs. By rebalancing annually or whenever an asset class deviates by more than 5% from its target weighting, you enforce a strict discipline of selling high and buying low without emotional guesswork.
