What Is It?
Risk parity is an asset allocation approach that allocates capital based on risk contribution rather than dollar amount. The goal is equal risk contribution from each asset class or factor, creating better diversification than traditional 60/40 portfolios.
Origin
Concept developed by Bridgewater Associates (All Weather fund, 1996) and formalized by Ray Dalio and Qian (2005). Addressed the problem of 60/40 portfolios where equities dominate risk (typically 90%+).
Why It Matters
Traditional allocation underweights diversifying assets. Risk parity better balances exposure across economic environments. It typically uses leverage to achieve equity-like returns with lower volatility. Understanding risk parity informs modern allocation thinking.
Intermediate Level
Market Mechanics
Principle: equal risk contribution (ERC) from each asset. Implementation: inverse-volatility weighting with leverage. Assets: equities, bonds, commodities (inflation protection). Leverage via futures or repo. Rebalancing maintains parity. Risk budgeting extends to factors.
How It Behaves
Lower volatility than traditional portfolios at comparable returns. Leverage amplifies both gains and losses. Works well in normal conditions; struggles when correlations spike. Rising rate environments challenge bond positions. Commodity exposure provides inflation hedge.

Institutional Behavior
Pension funds and endowments adopted risk parity post-2008. Some use internal management; others use funds of funds. Controversy around leverage and crowded exits. Smart beta variations target specific factors. Risk parity expanded to alternatives.
