We investigate modelling volatility surfaces using the alpha-stable Levy motion as the driving term in asset price uncertainty. The main motivation comes from natural generalization of Black-Scholes theory into the category of infinite activity jump processes, which enables one for more realistic modelling of stochastic dynamics observed in the market.
We derive the partial integro-differential equation connected with option price, discuss the existence and uniqueness of the solution of the latter equation and provide examples of volatility smiles obtained from numerically derived option prices.
