In this course we treat the foundations of mathematical finance, its fundamental concepts like arbitrage, equivalent martingale measures, and fundamental economic notions as preference relations and utility functions and show how these are applied in portfolio optimization. This will be done first for static markets and extended later on to a dynamic setting, where time is discrete. Finally we will show how stochastic control theory and dynamic programming can be applied to problems of portfolio optimization.
Aim and objectives
The general aim is to make students familiar with the mathematical foundations of mathematical finance in discrete time and the fundamentals of portfolio selection. In particular, students will able to prove a number of well selected theorems and demonstrate in assignments that they master the theory.
Specific objectives to be met at the end of the course:
- Students are familiar with fundamental concepts of financial mathematics and know how to apply them.
- Students know the theory behind portfolio optimization and know how to solve such optimisation problems.
- Students are able to optimize under order restrictions.
- Students know results about dynamic arbitrage theory and completeness in multi-period (discrete time) models.
- Students know how to apply dynamic programming to investment-consumption problems.
"Portfolio Theory" is generally structured as a second-year course in the Master's programmes of Mathematics and Stochastics and Financial Mathematics at the University of Amsterdam. Prospective students should be conversant with fundamental concepts of probability and measure theory, as covered in the "Measure Theoretic Probability" course.
A set of lecture notes also containing the exercises will be the main source for this course.
The course is mainly based on the book Stochastic Finance - An Introduction in Discrete Time by H. Föllmer and A. Schied.
