Obiettivi formativi
The student will have the familiarity with the elements of the stochastic calculus and with the main models describing the random evolution of the financial prices. He/She will be able to compute the price of derivative options and to discuss the assumptions of the different modelling choices. The student will be able to use stochastic calculus tools to model financial assets, derivatives, and portfolios.
