Abstract EN

The aim of this article is to spotlight the importance of the Brownian motion which allow for evaluating options in the financial market and demonstrate some main characteristics of these models and explain their applications in the financial mathematics which is the reference model proposed by Black-Scholes-Merton(BSM) that is widely used in finance and used mainly in the study of the option evaluation problem on the basis that the geometric Brownian motion is random and suitable for describing the trajectories of the prices of financial assets.

In the study, (BSM) model is presented in continuous time to determine the evolution of the options price on a sample of the shares of 12 banks listed on the Qatar financial market for the 2015 period.

The results show that the (BSM) option pricing method is perfectly suited to the most specific needs of investors, who manage important positions in the markets.

In this context, these models are particularly effective tools for making investment decisions that are accurate, fast and necessary to risk management.
