We have seen a renewed interest in how the $VIX settlement price is computed, as it pertains to expiring $VIX futures and $VIX options. Most of this interest has come from people who feel that they may have been “duped” by a somewhat biased settlement of $VIX. This is a false notion, fostered by the fact that $VIX has often “jumped” or “gapped” from its close on the last trading day (a Tuesday) to the morning settlement price (on Wednesday morning).
