Abstract: The short course covers the basic tools to model and solve an optimal portfolio problems, that is, the problem of selecting the best stocks of a financial market. Special emphasis is posed on the links between the three operational problems: model formulation, parameters estimation, computational solution. 

Program:

Lesson 1 (Part 1): The Roots of Optimal Portfolio Models.

The Markowitz Optimal Portfolio Problem. Mathematical properties, parameters estimation, experimental results.
The Von Neumann-Morgenstern Utility Theory. Risk adverse and risk taker investor’s behavior. Optimal portfolios of utility maximizer investors. 

Lesson 1 (Part 2): Portfolio models with non-invertible covariance matrices. 

The difficulty of estimating the covariance matrix and three solutions: The Mean/Absolute-Deviation portfolio model, the Markowitz model with cardinality constraints, Shrinkage estimators of the Covariance matrix.

Lesson 2: Portfolio models with robust estimators.

Variance estimators that are robust. The Optimal Median portfolio model. The Median/Risk portfolio models, integer linear programming formulation, experimental results.
