In this paper we propose a coordinate descent algorithm for solving high dimensional risk parity problems. We show that this algorithm converges and is very fast even with large covariance matrices (n500). Comparison with existing algorithms also shows that it is one of the most efficient...

ESG investing has gained considerable traction over the past few years and, alongside smart beta, factor investing and alternative risk premia, is one of the current hot topics for the asset management industry. Nevertheless, even though large institutions such as insurance companies, pension...

In this article, we show how to take into account skewness risk in portfolio allocation. Until recently, this issue has been seen as a purely statistical problem, since skewness corresponds to the third statistical moment of a probability distribution. However, in finance, the concept of...

Risk parity is an allocation method used to build diversified portfolios that does not rely on any assumptions of expected returns, thus placing risk management at the heart of the strategy. This explains why risk parity became a popular investment model after the global financial crisis in...

The emergence of net zero emissions policies is currently one of the most important topics among asset owners and managers. It considerably changes portfolio allocation and the investment framework of both passive and active investors. The academic literature generally concludes that...

These presentation slides have been written for the Advanced Course in Asset Management (theory and applications) given at the University of Paris-Saclay. They contain 5 lectures (Part 1. Portfolio Optimization Part 2. Risk Budgeting Part 3. Smart Beta, Factor Investing and Alternative Risk...

Like ESG investing, climate change is an important concern for asset managers and owners, and a new challenge for portfolio construction. Until now, investors have mainly measured carbon risk using fundamental approaches, such as with carbon intensity metrics. Nevertheless, it has not been...

The ongoing economic crisis has profoundly changed the industry of the asset management, by putting risk management at the heart of most investment processes. This new risk-based investment style does not rely on returns forecasts and is therefore assumed to be more robust. In 2011, it has...
