Abstract
Financial assets’ risk is considered as heteroskedastic, and is generally modelled with GARCH models. However, this risk is perceived in the same manner, only external events change, such as returns and historical risk. The way these events are treated by investors, is assumed static. Some scholars explain that risk perception is subject to structural breaks, which are not taken under consideration in GARCH models. For this reason, this paper aims to develop the switching regime GARCH model SWGARCH. Results clearly show that the SWGARCH can capture the risk dynamics of the studied indexes better than classical models.
