“…We can observe that the logarithm of VIX futures price is a linear function of the contemporaneous and lagged items of the logarithmic VIX. This is consistent with previous studies (Jiang et al,
2022; Wang et al,
2022; Yin et al,
2021), but different from continuous‐time models (Mencía & Sentana,
2013; Park,
2016) and the discrete‐time HN‐GARCH model (Wang et al,
2017), where VIX futures price only depends on VIX at the current time. More importantly, the realized semivariances of VIX information at current time t are also incorporated into the VIX futures pricing via the conditional variances
and
in our proposed model.…”
