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.

Statistical analysis of effect of financial crisis of 2007 in vehicles and transport sector in brazil / AnÃlise estatÃstica do efeito da crise financeira de 2007 no setor de veÃculos e transportes no brasil

Francisco Osair Soares Nobre 19 December 2011 (has links)
nÃo hà / This article aims to measure and analyze potential impacts from the financial crisis of 2007 in the sector of transport and vehicles and in Brazil, whose growth in recent years surpassed many other sectors of the economy and the Brazilian Gross Domestic Product. To this end, it was made use of descriptive statistics associated with various forms of risk, and performance of the distributions of nominal daily return of companies that make up this sector, every six months, from 2005 to 2010 was used as benchmark some market and industry indexes. Due to some factors, among them, heavy subjection on credit for the sale of new vehicles and export profile associated with the most important companies in this sector, it was observed that the daily returns of the shares of individual companies, as well as the return of representative aggregated index of this sector, reacted to the crisis with accumulated expressive losses. Some shares have accumulated losses of more than 80% in value, as occurred with TPIS3, and fairly high standard deviation up to 12.66% for WISA4. Both the direction of change as the value of the shares were provided by outline micro founded given by the Capital Asset Pricing Model (CAPM). In the postcrisis period, the industry reacted to a greater extent more than it was expected by fundamentals and the returns of firms and the aggregate index of the sector exceeded all other indexes analyzed in this study. At the same time that the results exceeded the returns of other indices, statistical analyzes were favorable to the sector of transport vehicles and having smaller standard deviation and better indications of Sharpes, Sortino, Treynor and Calmar. / Este artigo visa mensurar e analisar os possÃveis impactos oriundos da crise financeira de 2007 no setor de veÃculos e transportes no Brasil, cujo crescimento nos Ãltimos anos superou o de vÃrios outros setores da economia e do prÃprio Produto Interno Bruto brasileiro. Com este intuito, fez-se uso de estatÃsticas descritivas associadas Ãs diversas formas de risco e de performance das distribuiÃÃes de retorno lÃquido nominal diÃrio das empresas que compÃem este setor, com periodicidade semestral, de 2005 a 2010 e utilizou-se como benchmark alguns Ãndices de mercado e setoriais. Em razÃo de alguns fatores, possivelmente entre eles, forte dependÃncia de crÃdito para a venda de veÃculos novos e do perfil exportador associado Ãs principais empresas deste setor, observou-se que os retornos diÃrios das aÃÃes das empresas individuais, assim como o retorno de um Ãndice agregado representativo desse setor, reagiram à crise com perdas acumuladas expressivas.Algumas aÃÃes sofreram perdas acumuladas de mais de 80% em seu valor, como ocorreu com TPIS3, e desvio padrÃo bastante elevado de atà 12,66% no caso da WISA4. Tanto a direÃÃo da variaÃÃo como o valor das aÃÃes foram previstos pelo arcabouÃo microfundamentado dado pelo Capital Asset Pricing Model (CAPM). No perÃodo pÃs-crise, o setor reagiu em maior intensidade que a prevista pelos fundamentos e os retornos das empresas e do Ãndice agregado do setor superaram o de todos os outros Ãndices analisados neste estudo. Ao mesmo tempo em que os retornos superaram os resultados dos outros Ãndices, as anÃlises estatÃsticas foram favorÃveis ao setor de veÃculos e transportes apresentando menor desvio padrÃo e melhores Ãndices de Sharpe, Sortino, Treynor e Calmar.
