The aim of this thesis is to study the robustness of the optimal trading strategy. The setting we consider is that of a stochastic asset price model where the trend follows an unobservable Ornstein-Uhlenbeck process. In the first chapter, the background and the objectives of this study are presented along with the different methods used and the main results obtained. The question addressed in the second chapter is the estimation of the trend of a financial asset, and the impact of misspecification. Motivated by the use of Kalman filtering as a forecasting tool, we study the problem of parameters estimation, and measure the effect of parameters misspecification. Numerical examples illustrate the difficulty of trend forecasting in financial time series...
