Part of the Dynamic Modeling and Econometrics in Economics and Finance book series (DMEF, volume 4)


We discuss the question of portfolio selection when the returns of the assets under consideration are characterized by a heavy-tailed distribution. As distributional assumption we consider the sub-Gaussian stable model and address the problems of estimation and portfolio optimization. The advantages for risk assessment when relaxing the normal assumption in favor of the heavy-tailed variant are illustrated empirically.
