Determining the Implied Volatility in the Dupire Equation for Vanilla European Call Options
نویسندگان
چکیده
The Black-Scholes model gives vanilla Europen call option prices as a function of the volatility. We prove Lipschitz stability in the inverse problem of determining the implied volatility, which is a function of the underlying asset, from a collection of quoted option prices with different strikes.

Dynamic Hedging in a Volatile Market
In financial markets, errors in option hedging can arise from two sources. First, the option value is a nonlinear function of the underlying; therefore, hedging is instantaneous and hedging with discrete rebalancing gives rise to error. Frequent rebalancing can be impractical due to transaction costs. Second, errors in specifying the model for the underlying price movement (model specification ...
متن کاملPricing Barrier Options under Local Volatility
We study pricing under the local volatility. Our research is mainly intended for pedagogical purposes. In the first part of our work we study the local volatility modeling. We derive the local volatility formula in terms of the European call prices and in terms of the market implied volatilities. We propose and calibrate to the DAX option data a functional form for the implied volatility which ...
متن کاملThe real P&L in Black-Scholes and Dupire Delta hedging
We derive the real Profit&Loss(P&L) that accrues in what option traders do every day: continuously Delta (∆)-hedge a call, by substituting the option’s running implied volatility (generally stochastic) into the Black-Scholes(BS) ∆-formula. The result provides formal justification for a heuristic rule-of-thumb that a trader’s P&L on continuously ∆-hedged positions is his vega times times the dai...
متن کاملDupire’s Equation for Bubbles
We study Dupire’s equation for local volatility models with bubbles. The equation for call options contains extra terms compared to the usual equation, whereas, surprisingly enough, the Dupire equation for put options does not contain any extra terms. We also note that uniqueness of solutions to the Dupire equation is lost in general, and we show how to single out the option price among all pos...
متن کاملVolatility Surface Calibration In Illiquid Market Environment
In this paper, we show the fragility of widely-used Stochastic Volatility Inspired (SVI) methodology. Especially, we highlight the sensitivity of SVI to the fitting penalty function. We compare different weight functions and propose to use a novel methodology, the implied vega weights. Moreover, we unveil the relationship between vega weights and the minimization task of observed and fitted pri...
