The database consists of five most liquid share among the different segments of Bovespa Index. For the proposed methodology we used two of the empirical theories of the empirical literature - adjusted historical simulation and realized volatility. The Kupiec tes and Christoffersen test are used to analized and veryfy the proposed methodology performance. / O presente trabalho propõe para o cálculo VaR o modelo de simulação histórica, com os retornos atualizados pela volatilidade realizada calculada a partir de dados intradiários. A base de dados consiste de cinco ações entre as mais líquidas do Ibovespa de distintos segmentos. Para a metodologia proposta utilizamos duas teorias da literatura empírica – simulação histórica ajustada e volatilidade realizada. Para análise e verificação do desempenho da metodologia proposta utilizamos o Teste de Kupiec e o Teste de Christoffersen.
