WebbIn regression 1, the Fama-MacBeth regression (1973) is applied and no independent variables are priced. The beta of ∆VIX has a t-statistic of 0.21 and it is a poor explanatory variable. This is opposite to the finding of Ang et al. (2006). They found the price of VIX is - 0.080 which has the t-statistic of -2.49.
