WebJul 1, 2024 · Conclusions. This study uses GARCH-EVT-copula and ARMA-GARCH-EVT-copula models to forecast and simulate the one-day-ahead returns of ten stock indexes. Using the forecasts, we employ three portfolio optimization techniques (Min-CVaR, GMV and CET) to compute the optimal weights and perform portfolio back-testing for the out … A conditional Extreme Value Theory (GARCH-EVT) approach is a two-stage hybrid method that combines a Generalized Autoregressive Conditional Heteroskedasticity (GARCH) filter with the Extreme Value Theory (EVT). The approach requires pre-specification of a threshold separating distribution tails from its middle part. The appropriate choice of a threshold level is a demanding task. In this paper ...
