We measure the loss potential of Hedge Funds by combining three market risk measures: VaR, Draw-Down and Time Under-The-Water. Calculations are carried out considering three different frameworks regarding Hedge Fund returns: i) Normality and time-independence, ii) Non-normality and...

The rate of failure in quantitative finance is high, and particularly so in financial machine learning. The few managers who succeed amass a large amount of assets, and deliver consistently exceptional performance to their investors. However, that is a rare outcome, for reasons that will become...

In this article, I advocate for the use of causal graphs to modernize the field of factor investing, and set it on a logically-coherent foundation. In order to do that, first I must introduce the concepts of association and causations. Second, I explain the use of causal graphs and the real...
