Asymptotic equivalence in Lee's moment formulas for the implied volatility and Piterbarg's conjecture [PDF]

arXiv, 2010
The asymptotic behavior of the implied volatility associated with a general call pricing function has been extensively studied in the last decade. The main topics discussed in this paper are Lee's moment formulas for the implied volatility, and Piterbarg's conjecture, describing how the implied volatility behaves in the case where all the moments of ...

Pricing VIX options under the Heston-Hawkes stochastic volatility model [PDF]

arXiv
We derive a semi-analytical pricing formula for European VIX call options under the Heston-Hawkes stochastic volatility model introduced in arXiv:2210.15343. This arbitrage-free model incorporates the volatility clustering feature by adding an independent compound Hawkes process to the Heston volatility.
