GestÃo de risco das principais tesourarias de fundos de investimento em aÃÃes no Brasil / Risk management of major treasuries of funds investing in shares in Brazil

Antonio GlÃnio Moura Ferreira 10 February 2014 (has links)
nÃo hà / O presente trabalho busca analisar, empiricamente, o comportamento do modelo de mensuraÃÃo de risco de mercado Value-at-Risk â VaR em sua interpretaÃÃo paramÃtrica gaussiana incondicional e extensÃes que regulam as violaÃÃes sobre a nÃo normalidade e a heterocedasticidade dos retornos diÃrios dos fundos de investimentos em AÃÃes, das treze maiores instituiÃÃes financeiras residentes no Brasil, durante o perÃodo de janeiro/06 a dezembro/12. Para uma melhor avaliaÃÃo dos dados, buscou-se, inicialmente, modelar a evoluÃÃo condicional do risco e ajustar a idiossincrasia estatÃstica das sÃries temporais das treze tesourarias, utilizando distribuiÃÃes de probabilidade que mais se adaptassem à anÃlise dos modelos. Os resultados obtidos com esses modelos sÃo analisados à luz do teste para proporÃÃo de falhas proposto por Kupiec (1995) e Chisttoffersen (1998). A pesquisa ainda apresenta, com exemplos grÃficos, uma anÃlise de desempenho Risco â Retorno dos treze bancos utilizando a metodologia proposta por Balzer. / This study aims to examine empirically the behavior of the model for measuring market risk Value at Risk - VaR in its parametric interpretation unconditional Gaussian and extensions that regulate violations on heteroscedasticity and non-normality of daily returns of investment funds Actions, of the thirteen largest financial institutions resident in Brazil, during the January/06 dezembro/12. For a better evaluation of the data, we sought to initially model the conditional evolution of risk and adjust the statistic al idiosyncrasy of temporal series of thirteen treasuries, using probability distributions that best adapt to the analysis of the models. The results obtained with the semodels are analyzed by the test failure rate proposed by Kupiec (1995) and Chisttoffersen (1998). The survey also shows, with graphic examples, a performance Risk - Return of the thirteen banks using the methodology proposed by Balzer.
