Higher-Moment Risk Parity for Non-Normal Asset Returns

Summary

This research note outlines an extension to traditional risk parity. Standard risk parity assigns equal contributions to portfolio volatility, but this approach accounts for only variance and can leave exposure to skewness and kurtosis uneven. Those higher moments can matter during tail events, when assets with non-normal return distributions may behave differently from what variance alone suggests.

The proposed method adds higher-moment terms to the portfolio optimization objective, aiming to balance risks beyond volatility. The note reports that its calculations show better performance than traditional risk parity when asset returns are non-normal and correlations are relatively high. It gives no specific datasets, test period, benchmark details, or performance figures, so the reported advantage cannot be independently assessed from this summary. The result is presented as conditional; it does not establish that higher-moment risk parity will outperform in all markets or regimes.

Key ideas

• Traditional risk parity equalizes asset contributions to portfolio volatility but focuses on variance.
• Skewness and kurtosis can create risk imbalances that become important during tail events.
• The proposed extension adds higher-moment terms to the portfolio optimization objective.
• The note reports stronger results under non-normal return distributions and relatively high correlations.
• The provided summary does not specify the test design or establish performance across other conditions.
