The student will have the familiarity with the elements of the stochastic calculus and with the main models describing the random evolution of the financialprices. He/She will be able to compute the price of derivative options and to discuss the assumptions of the different modelling choices. He/She will be able to estimate volatility, implied volatility and risk premia.
