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.

本文探讨货币政策对於股市报酬之影响，选取货币政策代理变数－金融业隔夜拆款利率在分别采用Component-GARCH-Constant Jump与ARJI-Trend模型，并同时考量报酬率呈现非常态之特性，因此采用偏态t分配(skewed student t-distribution)进行估计条件变异数的恒常与移转部份及跳跃机率与跳跃频率，以捕捉政府实施预期及非预期的货币政策对股市报酬的影响，分析在预期及非预期的货币政策冲击下对股市的影响是否存在不同之效果。

In the empirical analysis part, statistical descriptions on the sample funds are made firstly, which show that the actual distribution of each sample fund"s daily net value return possesses the characteristic of leptokurtosis. So it is necessary to add student T distribution and GED to capture such leptokurtosis characteristic other than normal distribution. Secondly, ARCH test shows that there exists volatility clustering in each sample fund"s daily net value return, so GARCH related models should be used to describe such volatility clustering characteristic.

实证分析部分首先对样本基金进行统计描述，得出其收益序列均存在尖峰厚尾特征，不服从正态分布，因此有必要在下面的VaR计算中加入T分布和GED分布来捕捉这种尖峰厚尾特征；并且经ARCH检验后得出收益序列存在明显的波动聚集性的特征，因此可以选择GARCH类模型来描述这种特性，经过模型筛选，得出最适合我国开放式股票型基金的收益波动性模型为GARCH(1，1)模型。
