Numerical Finance
ECTS : 3
Description du contenu de l'enseignement :
The course bears on the modeling and numerical analysis of financial derivatives. The objectives are:
- Understanding the financial meaning of the related mathematics: model parameters, implied volatility, Greeks.
- Learning how to derive a pricing equation based on the probabilistic formulation of a model, possibly with stochastic volatility and/or jumps,
- Learning how to implement a theta-scheme of finite differences or a tree pricing method,
- Learning simulation Monte Carlo pricing and Greeking methods: basic principles and variance reduction techniques, first in a set-up of random variables or vectors, then in a dynamic set-up of stochastic processes.
Course outline:
1) Motivating examples: Black-Scholes and Dupire model, Realized volatility vs Implied volatility vs Local volatility,
2) Derivation of the Pricing Equations in various models,
3) Deterministic Pricing Schemes: Finite Differences methods and Tree Methods
4) Simulation Pricing Schemes: simulation of random variables and stochastic processes, Pseudo Monte Carlo versus Quasi Monte Carlo, variance reduction techniquesCompétence à acquérir :
