“…The VIX, as a measure of the implied 30‐day volatility of the SPX options, can be derived from the joint dynamics. The second one is to specify the VIX dynamics or the logarithmic VIX dynamics directly (e.g., Drimus & Farkas, ; Goard & Mazur, ; Grünbichler & Longstaff, ; Park, ), which is the route we take in this paper. In accordance with market practice, the hedging of options on the VIX usually makes use of corresponding futures, the pricing of VIX options, therefore, can be addressed by directly assuming the VIX dynamics, analogous to the valuation of stock index options.…”
