This paper examines whether or not stock return responds asymmetrically to monetary policy shocks. We use over-night rate volatility to measure monetary policy and apply Component-GARCH-Constant Jump and ARJI-Trend model to capture expected and unexpected effects of government's monetary policy on the stock return in American, Canada, Japan, and Britain. Considering the non-normality features of these assets returns, this paper use skewed student t distribution to estimate the relationship between the permanent and transitory components of the conditional variance and the frequency and intensity of jump of stock return.
