corresponding local volatility surface can be found via the well-known Dupire’s formula see e g Itkin (2015) and references therein The second approach relies on the direct solution of the Dupire equation using either analyt-ical or numerical methods The advantage of this approach is that it guarantees no-arbitrage 1
When the underlying asset is a continuous martingale call option prices solve the Dupire equation a forward parabolic PDE in the maturity and strike variables By contrast when the underlying asset is described by a discontinuous semimartingale call prices solve a partial integro-di erential equation (PIDE) containing a non-local integral
local volatility framework is the Dupire formula that links the local volatilities ?l(tSt) to the implied volatility surface Theorem 1 (The Dupire Formula) Let C= C(KT) be the price of a call option as a function of strike and time-to-maturity Then the local volatility function satis?es ?2 l (TK) = ?C ?T + (r q)K ?C ?K + qC
1 The derivation by Dupire [2] that uses the Fokker-Planck equation 2 The derivation by Derman et al [3] of local volatility as a conditional expectation We also present the derivation of local volatility from Black-Scholes implied volatility outlined in [1] We will derive the following three equations that involve local volatility ? = ?(S
Dupire Local Volatility and Heston model was introduced Moreover rough Heston model will also be discussed in the following passage 2 Local Volatility The concept of a local volatility was developed when Bruno Dupire Emanuel Derman and Iraj Kani noted that there is a unique di usion process consistent with the risk neutral densities
THE DUPIRE FORMULA MARK H A DAVIS Introduction The Dupire formula enables us to deduce the volatility function in a local volatilitymodel from quoted put and call options in the market1 In a local volatility model the asset price modelunder a risk-neutral measure takes the form (1 1) dSt =?(t)Stdt+ ?(t˜St)StdWt
