WebKeywords: Portfolio Selection, Extreme Value Theory, Tail Dependence JEL: C58, G11 1. Introduction In this paper we apply portfolio selection techniques to a sample of large-cap stocks using lower tail dependence (˜) as the measure of risk. The concept of tail dependence comes from Extreme Value Theory (EVT), which allows us to describe Extreme value theory or extreme value analysis (EVA) is a branch of statistics dealing with the extreme deviations from the median of probability distributions. It seeks to assess, from a given ordered sample of a given random variable, the probability of events that are more extreme than any previously … See more Two main approaches exist for practical extreme value analysis. The first method relies on deriving block maxima (minima) series as a preliminary step. In many situations it is customary and convenient to … See more Applications of extreme value theory include predicting the probability distribution of: • Extreme floods; the size of freak waves • Tornado outbreaks • Maximum sizes of ecological populations See more Extreme value theory in more than one variable introduces additional issues that have to be addressed. One problem that arises is that one must specify what constitutes an extreme event.
