Os impactos da crise financeira de 2008 nas aÃÃes das instituiÃÃes brasileiras / The impacts of the 2008 financial crisis in the shares of Brazilian institutions

Josà Eduardo de Carvalho Lima 15 June 2012 (has links)
nÃo hà / O objetivo do presente estudo visou investigar possÃveis impactos provenientes da crise financeira de 2008 nas aÃÃes das instituiÃÃes financeiras brasileira. Logo apÃs duas dÃcadas de instabilidade, planos econÃmicos malsucedidos e ciclos de crescimento pouco consistentes, chegou-se finalmente, apesar de alguns problemas, diante de um conjunto concreto de oportunidades para avanÃar significativamente no mercado financeiro. O Brasil assegurou diante do mundo um nÃvel de excepcional desempenho no setor financeiro, com instituiÃÃes financeiras que se projetaram como modelos de excelÃncia nos mais diversos segmentos de atuaÃÃo. Com esta finalidade, foram utilizadas algumas mÃtricas estatÃsticas descritivas agregadas Ãs diversas formas de risco e de performance das distribuiÃÃes de retorno lÃquido nominal diÃrio das aÃÃes das empresas que compÃem setor analisado, com periodicidade semestral de 2005 a 2010. Utilizou-se como benchmark o IBOVESPA. Possivelmente em funÃÃo de alguns fatores como, a forte contraÃÃo do crÃdito, o nÃvel de desconfianÃa dos investidores nos sistemas financeiros e diminuiÃÃo da demanda externa pelos produtos brasileiros, fizeram com que os retornos diÃrios das aÃÃes das empresas individuais, assim como o retorno do Ãndice de mercado IBOVESPA, reagissem à crise com perdas acumuladas expressivas. A direÃÃo da variaÃÃo e o valor das aÃÃes foram previstos pelo arcabouÃo microfundamentado dado pelo Capital Asset Pricing Model (CAPM). No perÃodo pÃs-crise, o setor reagiu e demonstrou uma significativa recuperaÃÃo prevista pelos fundamentos e os retornos das aÃÃes das instituiÃÃes superaram o Ãndice de mercado. Ao mesmo tempo as anÃlises estatÃsticas foram favorÃveis ao setor financeiro, apresentando menor desvio padrÃo e boa performance dos Ãndices de Sharpe, Sortino, Treynor e Calmar. Com a utilizaÃÃo do CAPM, e das regressÃes computacionais estimadas, testando os retornos das aÃÃes das instituiÃÃes financeiras analisadas, o estudo demonstrou que as aÃÃes acompanharam as movimentaÃÃes do mercado, variando positivamente o que deveria e desvalorizando quando os fundamentos sinalizavam que deveriam, mostrando-se de acordo com a teoria de precificaÃÃo de ativos. / The aim of this study was to investigate possible impacts from the 2008 financial crisis in the actions of the Brazilian financial institutions. Soon after two decades of instability, economic plans and unsuccessful cycles of growth inconsistent, it was finally, despite some problems, before a concrete set of opportunities to advance significantly in the financial market. Brazil is assured before the world an exceptional level of performance in the financial sector, with financial institutions that are designed as models of excellence in various segments. For this purpose, we used some descriptive statistics aggregated metrics to the various forms of risk and performance of the distributions of nominal daily net return of the stocks of companies that comprise the sector analyzed, every six months from 2005 to 2010. Was used as the benchmark Bovespa Index. Possibly due to such factors as the sharp contraction of credit, the level of distrust of investors in financial systems and reduced foreign demand for Brazilian products, made daily stock returns of individual companies, as well as the return of the index IBOVESPA market, react to the crisis with significant accumulated losses. The direction of change and shareholder value have been provided by microfundamentado framework given by the Capital Asset Pricing Model (CAPM). In the post-crisis period, the industry reacted and demonstrated a significant recovery predicted by fundamentals and stock returns of institutions exceeded the market index. While statistical analyzes were favorable to the financial sector, with lower standard deviation and good performance of the Sharpe ratios, Sortino, Treynor and Calmar. Using the CAPM, and the computational estimated regressions, testing the stock returns of financial institutions analyzed, the study demonstrated that accompanied the stock market movements, which should vary positively and devaluing the fundamentals signaled when they should, showing in accordance with the theory of asset pricing.
