Abstract in Portuguese
O trabalho é um estudo baseado no modelo de volatilidade estocástica de Heston (também conhecido como Cox-Ingersoll-Ross ou Feller). Adotamos a solução semi-analítica proposta por Dragulescu e Yakovenko para explicar as distribuições condicionais de retornos do Ibovespa (índice Bovespa). Verificamos que a distribuição resultante do modelo se ajusta muito bem à distribuição observada, de escalas que vão de 1 minuto a 100 dias. Os resultados têm relevância para as áreas de gerenciamento de risco e para a prática de negociação no mercado acionário e derivativos

Abstract in English
The work is a study based on the stochastic volatility model of Heston (also known as Cox-lngersoll-Rosé or Feller model). We use the semi-analytic solution developed by Dragulescu and Yakovenko to explain the condicional distribution of the returns of the lbovespa (Bovespa index). We verify that the resulting distribution of the model fits very well the observed distribution, in scales that go from l minute to 100 days. The results are relevant for risk management and for the practice of the stock market and derivatives trading
