Resumen de El modelo matemático lognormal para valorar activos financieros: un enfoque didáctico

Gemma Calbo Sanjuan

• This paper provides two different ways to introduce the well-known model for describing the price of a financial asset. The model is usually called geometric Brownian motion. The first approach is based up to introduce uncertainty from deterministic framework for valuation of assets free of risk. The second one requires the introduction ofa special calculus namely Itô´s Calculus. This last topic is presented in an elementary way in order to take advantage in the classroom.
