This course covers numerical methods for PDEs in finance: pricing methods (numerical calculation of derivative prices and Greeks) and model calibration.
- Pricing methods using Fourier transforms.
- Tree-based pricing methods –The Cox-Ross-Rubinstein binomial tree. The Kamrad-Ritchken trinomial tree. Case study: barrier and Bermuda options.
- Finite difference methods forpricing –Theta-schemes in dimension one of space. ADI methods in higher dimensions. Case study: Asian options, cliquet options, volatility and variance swaps.
- Calibration methods –Calibration of parametric models by non-linear least squares. Calibration of non-parametric models by regularised non-linear least squares. Case study: Extraction of effective volatility.
