The main objective of this course is to apply the stochastic calculation on the valuation and hedging problems of financial products in a general multi underlying framework. The classic models (Black-Scholes-Merton) will be reviewed from this angle as well as on the one hand rate models and on the other hand models with local volatility. Significant emphasis will be placed on the risk neutral approach.
The course outline will follow the scheme:
Integrals and Itô formulas multidimensional case;
Black-Scholes-Merton equation, for EDP view;
Multivariate Stochastic Computation, trajectory approach;
Neutral risk valuation: Girsanov theorem, probability neutral probability, representation of Brownian Martingales, Fundamental pricing theorems;
Back to the EDP approach: Feynman-Kac 1d and muti-d formula;
Models with local volatility: Dupire formula.
