Bridgewater All Weather: Risk Parity Across Growth and Inflation Regimes

Article BigQuant

Summary

This article explains the All Weather approach as a way to build a portfolio without relying on precise economic-cycle forecasts. It frames the macro environment along growth and inflation dimensions, then describes matching stocks, bonds, commodities, gold, and cash-like holdings to different combinations of those conditions. Its central construction principle is risk parity: allocate by each asset’s contribution to portfolio risk rather than by equal dollars, with leverage discussed as a means of balancing lower-risk holdings. The proposed implementation measures tail risk with expected shortfall and rebalances on a fixed schedule.

The article also discusses why a simple economic-cycle allocation framework may fail when policy or other external shocks dominate. It cites historical performance figures and describes a later Nasdaq-and-gold variant, but the underlying tests and code are not presented in enough detail here to assess reproducibility, costs, or out-of-sample robustness. The author explicitly raises overfitting as a concern; the strategic rationale alone does not establish future performance.

Key ideas

  • The framework aims to reduce dependence on forecasting economic-cycle phases by diversifying across growth and inflation scenarios.
  • Risk parity weights holdings according to risk contribution rather than invested capital.
  • The proposed portfolio uses expected shortfall to account for tail losses and rebalances periodically.
  • Stocks, bonds, gold, commodities, and cash-like assets are assigned different roles across macro conditions.
  • The performance claims and later two-asset variant are not supported here with enough detail to independently evaluate them.
