Risk Parity

Risk parity is a portfolio-construction approach that allocates based on how much risk each asset contributes, rather than how many dollars are invested in it. In a conventional 60/40 portfolio, stocks take 60% of the dollars but, because they are so much more volatile than bonds, they contribute the overwhelming majority of the portfolio's actual risk — often 90% or more. A 60/40 investor is, in risk terms, almost entirely betting on stocks.

Risk parity tries to balance that. By holding more of the lower-volatility assets — typically bonds, and often using duration to give them enough punch — it aims for each asset class to contribute a roughly equal share of total portfolio risk. The goal is a portfolio that is genuinely diversified across economic environments rather than dominated by one, so that no single scenario, whether recession or boom, can devastate it.

Ray Dalio's All Weather Portfolio is the best-known retail expression of this idea, spreading risk across stocks, long- and intermediate-term bonds, gold, and commodities. The approach leans heavily on the correlation between assets: it works best when the holdings respond differently to growth and inflation surprises, so their risks partly offset. Institutional risk-parity funds often add leverage to raise the expected return of a bond-heavy mix, though the retail versions on this site do not.

The main vulnerability is a period when normally diversifying assets fall together — as stocks, bonds, and gold-sensitive assets did during the 2022 rate shock — which temporarily undercuts the whole premise. Risk parity is not magic; it is a disciplined answer to the asset allocation question that prioritizes balance and resilience over chasing the highest possible return.
