    Abstract: 鑒于股市收益率常常表現出非對稱性和"尖峰""厚尾"等系統性的高階矩特征,本文在"均值-方差"CAPM和三因素模型等經典模型的基礎上加入高階矩風險,考查動量策略和反轉策略的收益率是否可以進一步被高階矩風險所解釋。以中國滬深股市1998年1月至2009年11月所有A股的月度收益為樣本,研究發現:(1)加入高階矩風險能顯著改進經典模型對兩種策略下輸家和零投資組合以及部分贏家組合收益率的解釋力;(2)動量效應并不顯著而反轉效應顯著存在;(3)經典模型不能解釋的動量策略輸家組合的超額收益可以由高階矩風險所解釋;(4)反轉策略下輸家組合比該策略下的贏家組合具有相對較高的因素風險和高階矩風險
