摘    要:利用GARCH(1,1)-N、GARCH(1,1)-T、EGARCH-N和EGARCH(1,1)-GED4种模型,结合标准正态分布、学生t分布、广义误差分布3种分布形态,对我国2003年前发行的17支开放式基金净值的波动是否存在不对称进行检验。结果显示,EGARCH(1,1)。N模型和EGARCH(1,1)-GED模型能较好地刻画我国开放式基金净值的波动特点,开放式基金净值收益的波动具有异方差性和不对称性,同时正向与负向期望收益对波动也有影响。

关 键 词:波动不对称  开放式基金净值  Engle-Ng检验

Abstract:We test the asymmetry of the NAV volatility of 17 open-end funds established before 2003, using GARCH(1,1)-N. GARCH(1,1)-T. EGARCH-N and EGARCH(1,1)-GED models, assuming, respectively, that the distribution of variation is normal distribution, student-t distribution and generalized error distribution. We find, first, EGARCH(1,1)-N and EGARCH(1,1)-GED models are more suitable for describing the volatility characteristics of open-end funds. Second, volatility of NAV return is heteroscedastic and asymmetric, and positive and negative expected returns affect volatility as well.
Keywords:asymmetry of volatility  open-end funds'NAV  Engle-Ng testing
