Risk parity – the benefits of a conditional approach

Risk parity is a meaningful and robust approach for building well-diversified portfolios, but it relies on historical volatility estimates, which penalises upside risk as well as downside risk and leads to a massive overweighting of bonds versus equities, even in a low yield environment. The authors from EDHEC Risk-Institute build the case for an alternative […]

Risk parity and beyond

This paper analyses whether the use of uncorrelated underlying risk factors, as opposed to correlated asset returns, can lead to a more efficient framework for measuring and managing portfolio diversification. The paper, by academics at EDHEC Business School and SYMMYS, acknowledges that the ability to construct well-diversified portfolios is a challenge of critical importance in […]

Deconstructing risk parity portfolios

In this paper MSCI applies its framework for defining macroeconomic risk to strategic asset allocation, labelling assets as either risk premium or risk hedging. It applies the analysis to arisk-parity portfolio, showing how its relatively high exposure to inflation shocks makes it a risk premium portfolio.   To access the paper click here

Just when you thought you were safe, the next reiteration of risk parity has arrived. AllianceBernstein’s tail risk parity takes the concept of risk parity, reallocating assets uniformly according to risk, but it uses tail risk, not volatility, as the core measure. The concept of risk parity is a portfolio diversified according to risk, rather […]

Risk parity manages risk regret

The risk parity approach to portfolio construction might not deliver results in a “bull stockmarket,” but remained a “robust and rigorous” methodology which also “managed risk regret over time.” These are the views of Wai Lee, chief investment officer of quantitive investment at New York-based fund manager Neuberger Berman, who was recently named winner of […]

New ways to calculate portfolio weights

This paper presents two simple algorithms to calculate the portfolio weights for a risk parity strategy, where asset class covariance information is appropriately taken into consideration to achieve “true” equal risk contribution. Previous implementations of risk parity either (1) used a naïve 1/vol solution, which ignores asset class correlations, or (2) computed “true” risk parity […]
