Abstract: A stochastic volatility model with error terms is considered following a generalized Fernandez-Steel distribution. Financial return data often exhibit characteristics such as heavy tails and skewness, which can be partially captured by the standard Fernandez-Steel distribution. However, by extending the distribution to allow connections at arbitrary quantile points (not just at the origin), the model gains greater flexibility. This enhancement is expected to improve the accuracy of forecasts for risk measures such as value-at-risk (VaR) and expected shortfall (ES).
