We investigate whether there is a pattern regarding the quality of several models and methods in expected shortfall (ES) estimation, considering distinct asset classes, estimation windows and significance levels. We use unconditional, conditional and quantile/expectile regression-based models....

We evaluated the performance of multivariate models for forecasting Value at Risk (VaR), Expected Shortfall (ES) and Expectile Value at Risk (EVaR). We used Historical Simulation (HS), Dynamic Conditional Correlation-Generalized Autoregressive Conditional Heteroskedastic (DCC-GARCH) and copula...

The relationship between returns and risk factors are likely to vary depending on the investor's time horizon, but CAPM supposes homogenous expectations. A relatively new approach known as wavelet analysis may help to reduce that problem, incorporating different time scales. Taking advantage of...
