摘　　要：用期权进行套期保值是常用的风险转移方法。假设标的股票服从更新跳跃-扩散过程,研究在保值者给定可接受的保值失败概率情况下,如何确定合理的套期保值比率。给出了计算最优套期保值率所需参数的估计方法,并用算例予以验证。Hedging with option trade is one of the most useful ways to distract risk. This paper assumes that the underlying price obeys a renewal jump-diffusion process, studies how to determine a sound hedge ratio when given an acceptable probability of hedge failing, and suggests the way to assume the parameter of calculating the optimal hedge ratio which is finally validated with an example. The result obtained can be useful for distracting risk with option hedge.
