How it works
Hierarchical Risk Parity Explained
- HRP was developed by Marcos Lopez de Prado. It uses hierarchical clustering on the correlation matrix to group assets by similarity, then allocates capital inversely proportional to volatility within each cluster. This naturally diversifies across uncorrelated risk sources.
No Expected Returns Required
- Unlike mean-variance optimization, HRP requires no expected return estimates — only the covariance matrix. Since expected returns are notoriously difficult to forecast accurately, this makes HRP significantly more robust in practice.
How Hierarchical Clustering Works
- The algorithm computes pairwise correlations between all assets, then builds a dendrogram (tree) that groups similar assets together. Capital is allocated starting from the leaves of the tree, ensuring diversification at every level of the hierarchy.
Frequently Asked Questions
- What is Hierarchical Risk Parity (HRP)?
- HRP clusters assets by correlation structure and allocates capital inversely proportional to volatility within each cluster. It requires no expected return estimates and is inherently diversified.
- Why use HRP over mean-variance optimization?
- HRP is robust to estimation error in expected returns, which is notoriously difficult to forecast accurately. By relying only on the covariance structure, it avoids the 'garbage in, garbage out' problem of MVO.
