Abstract
There is a wide spectrum of models available today describing the asset price underlying. The paper presents a new model for financial asset price fluctuations in which the changes in price occur at random time moments. The basic probabilistic concepts in modelling are developed, the economic interpretation of the model is discussed, arbitrage opportunities arising within the model are excluded. We also derive the closed form formulas for moments of the price process and investigate the framework of hitting times calculation. The analysis in asymptotics shows further that the process appearing in our model converges to the Wiener process. Some estimation results, obtained by the GMM, are presented.
