摘要:在我们的研究中,我们利用期权价格信息的前瞻性来估计股票的系统风险,同时控制特质偏度的影响。实证结果表明期权隐含的beta估计与随后的股票收益之间存在显着的正相关关系。根据我们的beta估计,短期投资组合的平均每月收益率为0.96%。我们还发现,期权隐含beta能预测未来实现的beta,期权隐含beta的风险溢价与未来市场回报正相关,并包含有关未来宏观经济变量的信息。

ABSTRACT
In our study, we take advantage of the forward-looking nature of information in option prices to estimate systematic equity risk while controlling for the effect of idiosyncratic skewness. Empirical results show a significantly positive relationship between the option-implied beta estimate and subsequent stock returns. A long–short portfolio based on our beta estimate earned an average monthly return of 0.96%. We also find that the option-implied beta predicts future realized betas and that the risk premium on the option-implied beta is positively associated with future market returns and contains information about future macroeconomic variables.
