N2 - This article investigates a new way of equity portfolio selection that provides maximum diversification along the uncorrelated risk sources inherent in the S&P 500. This diversified risk parity strategy is distinct from prevailing risk-based portfolio construction paradigms. Especially, the strategy is characterized by a concentrated allocation that actively adjusts to changes in the underlying risk structure. In addition, x-raying the risk and diversification characteristics of traditional risk-based strategies like 1/N, minimum-variance, risk parity, or the most-diversified portfolio, the authors find the diversified risk parity strategy to be superior. Although most of these alternatives crucially pick up risk-based pricing anomalies like the low-volatility anomaly, the diversified risk parity strategy more effectively exploits systematic factor tilts.
