APM_53650_EP - Processus Stochastiques et produits dérivés en temps discret et continu (2024-2025)

This course runs from September to December, 3 hours per week + exercise sessions.

This course provides an overview of derivatives from a modeling and risk management perspective. The markets considered range from traditional markets (stocks/equity indices, interest rates, foreign exchange) to the new crypto-currency markets.

Three speakers are planned for this course:

The derivatives market is an important element in the transfer of market risk between investors (banks, hedge funds, financial institutions,…). The objective of the course is to describe the financial products offered, and the theoretical and practical methods used in the market to value and hedge these financial products. The topics covered are the following.

II - Some alternatives to lognormal modeling

  1. Implicit distribution from data
