2.今天你阅读到的有价值的内容段落摘录
(1) In equity indexs the skew will be more pronounced than in the individual stocks that make up the index. So we can see that there two ways the index volatility can increase:either the component volatilitites or the correlation increase.
(2) Volatility isn't enough, the process was misspecified. We need to extend the BSM methodology to incorporate skewness and kurtosis.
3.今天你阅读到的有价值信息的自我思考点评感想
股指期权隐含波动率的偏度效应要比个股期权更明显,因为股指期权隐含波动率不止跟成分股相关,还与成分股之间的相关性有关。根据历史统计数据,个股之间的尾部相关特性是统计上显著的,因此较易出现微笑的曲线。
