Produce, through analysis and diagnosis, implemantable solutions in context and identify priorities for action. 6.1. Work in a team : Join in and collaborate with team members. Be open and take into consideration the different points of view and ways of thinking, manage differences and conflicts constructively, accept diversity. |

Content

The purpose of this course is to introduce the key mathematical concepts to understand the mechanics of derivatives pricing, both in discrete and continuous time. As a consequence, the language used in this course is quite formal and technical, but the equations are always put in perspective to highlight the intuition hidden behind.

These skills will be extensively used in LLSMS2226 (credit and interest rates risk)

- The course starts with a reminder about basic probability theory (events, probabilities, random variables, distributions, expectations, etc). Many of these concepts have already been used in previous courses, but some of them will be revisted in a more formal way, and new perspectives (such as changes of probability measures) will be introduced.
- We then introduce a time-dimension, dealing with stochastic processes in continuous and discrete time, such as the random walk, the scaled random walk, the Brownian motion and related processes.
- We explain how these processes can be used to build models to price financial derivative products by relying on the no-arbitrage theory and the notion of payoff replication. The focus is put on the binomial tree model and the Black-Scholes partial differential equation.
- The concepts, although quite theoretical, will be illustrated using numerical cases thanks to Monte Carlo simulation, facilitating the transfer from theory to practice.

These skills will be extensively used in LLSMS2226 (credit and interest rates risk)

Teaching methods

- Ex-cathedra course
- Optional exercise sessions
- Group project (in R or Python), consisting of pricing and risk-managing a derivatives product. The main objective of the projects is to make the concepts more concrete, which facilitates the learining processes.

Some optional homeworks may also be proposed, in order for the students to be able to assess the level of their understanding.

Evaluation methods

**Continuous evaluation (projects with implementation in R)**

- Date:
*Will be specified at the beginning of the course* - Type of evaluation:
*Report (teamwork, 20% of final grade) and Individual assessment (following the oral exam, during the examination session; 10% of final grade)*

**Evaluation week**

- Oral:
*No* - Written:
*No*

**Examination session**

- Oral:
*Yes* - Written:
*No* - Comments: The final examination is made of two parts :
*1h preparation of questions (exercises + theory) followed by a 10 to 15 min discussion with the professor (60% of final grade)**10 min discussion with the teaching assistant to assess the individual contribution of the student in the group project (10% of final grade).*

**Complementary information about the project**

*The grade of the project (both the group and individual parts) will be set to 0 for the students who would not present the individual examination scheduled the day of the exam. It is however possible to skip the oral exam, and to defend the individual part of the project only.*__In case of failure in first session:__the grade of the report of the project will be automatically transferred. The same holds for the individual part of the project, provided that it was successful in the first session. Otherwise, the student must retake the individual part in second session.__In case of failure in second session:__If both parts of the project were successful, the student gets a dispense for the project of the next academic year. Otherwise, the student must enroll in the project of the new academic year. It is the responsibility of the student to make sure (s)he joins a group !__Pay attention to the announcement on Moodle !__

**Important note about plagiarism and the use of generative AI**

*By submitting an assignment for evaluation, you assert that:*

*it accurately reflects the facts and to do so you need to have verified the facts, especially if they originate from generative AI resources;**all your sources that go beyond common knowledge are suitably attributed. Common knowledge**is what a knowledgeable reader can assess without requiring confirmation from a separate source;**you have respected all specific requirements of your assigned work, in particular requirements**for transparency and documentation of process, or have explained yourself where this was not possible.*

*If any of these assertions are not true, whether by intent or negligence, you have violated your commitment to truth, and possibly other aspects of academic integrity. This constitutes academic misconduct.*
