摘要
下偏矩作为风险的度量更适用于风险规避者。推导出考虑跳跃、对冲现货资产的最小下偏矩动态套期保值比率的估计量并构造套保策略。在实证中以中国沪深300指数为例运用股指期货构建套保组合,发现加入共跳因素后,无论对于多头还是空头套期保值者,对冲下偏风险的套保效率都有明显提升。
Lower partial moments are more appropriate risk measures for risk averse investor. This paper deduces the dynamic minimum lower partial moments hedge ratio estimates which allows for jumps. Strategy is suggested correspondingly. In empirical application, applied to hedging CSI300 stock index, stock index futures are used to construct hedged portfolio. It is found that for either short or long hedgers, the effectiveness of hedging downside risk has been improved obviously after adding common jumps.
