MA4269: Mathematical Finance II

Course Introduction

This course provides a clear understanding of the intuition behind derivatives pricing, how models are constructed, and how they are used and adapted in practice. Strengths and weaknesses of different models. Some important conceptions will be inclueded and tested: Black-Scholes, stochastic calculus, Martingale, exotic options, American options and Greeks.

Both the theory and the practice of the industry-standard pricing models are considered in detail. Each pricing problem is approached using multiple techniques including the well-known PDE and a change of measure.

Books

Preliminary knowledge

You should be familiar with basic concepts of financial derivatives though we will review them in the first lecture. A good introduction is one of the recommended book by John Hull: Options, Futures, and Other Derivatives. You must also have some basic knowledge in multivariable calculus and probability.
