Les objectifs du cours

Instructor 1 : Laurent Dahan

Instructor 2 : Xavier Bocher

Part 1 : Instructor 1 (18h)
The course objective is to understand the issue of risk management. The principal ways of understanding and learning about risk are considered.
Greeks computation is used to explain the daily P/L in a normal trading environment. The VaR is used to take into account market tail events while stress testing highlights performance under extreme market conditions. In a similar measure the course attempts to present the counterparty risk for market operations. This course shows also how all these measures come within the framework of the Basel Accords (3 pillars, regulatory capital requirements...)

Part 2 : Instructor 2 (12h)
Another important issue in risk management is to consider portfolio risk and multivariate models.
