The subject was developed in a way to encourage the usage of such practices by the local authorities, aiming at the improvement of regulators’ activities and the growth of brazilian capital market. Among the referred practices, the use of statistical models to evaluate the price of traded contracts was emphasized as a means to guide the enforcement actions on the surveillance of artificial conditions of trade. The approach to these models comprised from the definition of fundamental concepts to a case-study related with stock options, as well as the characterization of the main important models and methods of calculating the volatility of contracts price. The results of this research were related to the origins of the legal system and recent economic development in Brazil, which led to the sophistication of financing mechanisms, not being restricted to just pointing to the weak points of the local surveillance.
