Abstract:
Many option pricing formulas have been developed to overcome the restrictive assumptionsof Black and Scholes models and to give more accurate prices. Most of the methods arefocused on a point prediction of option price.In this paper, we propose a method that predicts a distribution of the implied volatilityfunctions by applying a Gaussian process regression and estimating con dence intervals ofoption prices using the predicted volatility distributions. To verify the performance of theproposed method, we conducted simulations on some model-generated option prices dataand real option market data. The simulation results show that the proposed method per-forms well with practically meaningful option ranges as well as overcomes the problem ofcontaining negative prices in their predicted con dence intervals by the previous works.
