Pricing and hedging of financial derivatives


Objective

The objective of the course is to provide an overview of the main methods for pricing and hedging risks on the financial markets. After a quick overview of the methods used in discrete-time models, we will mainly study continuous-time models. We will study these issues from a theoretical, practical and numerical point of view.
