The present thesis is a study of different optimal portfolio allocation problems in the case where the appreciation rate, named the drift, of the Brownian motion driving the dynamics of the assets is uncertain. We consider an investor having a belief on the drift in the form of a probability distribution, called a prior. The uncertainty about the drift is managed through a Bayesian learning approach which allows for the update of the drift's prior probability distribution. The thesis is divided into two self-contained parts; the first part being split into two chapters: the first develops the theory and the second contains a detailed application to actual market data. A third part constitutes an Appendix and details the data used in the app...
