In this thesis, we investigate the advantages of using high-dimensional copula modeling to understand the riskiness of portfolio investments and to more realistically estimate future portfolio values. Our approach involves benchmarking some pre-determined fitted copulas to the 0.05-quantile, the Tail Conditional Expectation, and the probability of negative returns for each portfolio. We find that the two R-Vine copula models used in this study provide good estimations of the distribution of portfolio values for the 1-month time frame, the shortest we consider in this thesis, most probably due to their flexibility and ability to represet a diverse array of dependence structures. However, for longer time frames (1 year or more), the Clayton c...
