Abstract:

?本文选取2002年1月至2011年6月期间我国期货市场较活跃的期货品种为样本,对其收益率、条件波动率、交易量和持仓量的周内效应进行实证,通过引入正态分布、Student-t分布及广义误差分布(GED)三种分布假设以刻画扰动项,更全面地检验周内效应的存在性及存在模式。实证结果显示我国期货市场周内效应受我国期货市场投资者结构的影响尤其是个人投资者的影响,检验的结论与研究方法有较大关系,其中误差项分布直接影响实证结论。实证结果还显示不同期货品种在不同样本时期表现为不同的周内模式,但总体上在期货市场整顿的初期未有周内效应,随后均呈现出正周一效应即反转的周一效应,且不同收益率的周内效应模式也不尽相同。
