Numerical Pricing and Hedging of Contingent Claims
This chapter introduces numerical methods for calculating prices and replication strategies of contingent claims. Only a few options can be priced and hedged explicitly, for instance, call and put options. For path-dependent derivatives like barrier and average (Asian) options there does not exist any explicit formula, and a numerical approach is necessary to evaluate them. We will introduce techniques based on Monte Carlo simulations of the risk-neutral expectation defining the derivatives price, and so-called finite-difference methods which numerically solve the Black & Scholes partial differential equation (4.12). Both approaches work for claims with payoff of the form f(S(T)), while the former is also applicable for more general claims.1
