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.
WebbThis example highlights how to implement a Fama-MacBeth 2-stage regression to estimate factor risk premia, make inference on the risk premia, and test whether a linear factor model can explain a cross-section of portfolio returns.
