1. TEORIA DOS VALORES EXTREMOS: VALOR EM RISCO PARA ATIVOS DE RENDA-FIXA / EXTREME VALUE THEORY: VALUE AT RISK FOR FIXED-INCOME ASSETS
Since the 90 decade, the use of Value at Risk (VaR) methodology has been disseminated among both financial and non-financial institutions around the world, as a good practice in terms of risks management. In spite of the fact that it does not take into account one of the most important characteristics of financial assets returns distribution - fat tails (exc

2. Modelagem estocástica em risco operacional aplicando teorias dos valores extremos
Nos últimos anos, a modelagem de risco operacional tornou-se fator crítico de sucesso para o gerenciamento de riscos em instituições financeiras. Com o advento do novo acordo de capital Basiléia II, diversos modelos de mensuração de risco operacional têm sido discutidos. Este trabalho preocupa-se em discutir métodos avançados e modernos na mensura�

3. Markets of risk and the theory of the extreme values: empirical study of cases / Mercados de risco e a teoria dos valores extremos: estudo empÃrico de casos
The objective of this work is to infer the behavior of extremes values of a continuous random variable, either extreme values in the down left tail of the probability density function (pdf), like the great daily losses in financial markets investments, or extreme values in the pdf upper right tail, like some great claim sizes in the insurance industry. The E

4. VALUE AT RISK A COMPARISON OF METHODS TO CHOOSE THE SAMPLE FRACTION IN TAIL INDEX ESTIMATION OF GENERALIZED EXTREME VALUE DISTRIBUTION / VALOR EM RISCO UMA COMPARAÇÃO ENTRE MÉTODOS DE ESCOLHA DA FRAÇÃO AMOSTRAL NA ESTIMAÇÃO DO ÍNDICE DE CAUDA DE DISTRIBUIÇÕES GEV
Value at Risk -VaR- is already part of the toolkit of financial analysts assessing market risk. In order to implement VaR it is needed to estimate low quantiles of the portfolio returns distribution. Traditional methodologies combine a normal conditional distribution together with ARCH type models to accomplish this goal. Albeit well succeed in evaluating ri

5. EXTREME VALUE THEORY: A CONDITIONAL APPROACH FOR VALUE AT RISK ESTIMATION IN THE BRAZILIAN STOCK MARKET / A TEORIA DOS VALORES EXTREMOS: UMA ABORDAGEM CONDICIONAL PARA A ESTIMAÇÃO DE VALOR EM RISCO NO MERCADO ACIONÁRIO BRASILEIRO
The existence of fat tails is one of the striking stylized facts of financial returns distribution. This fact makes the use of traditional parametric models for Value at Risk (VaR) stimulation unsuitable for the estimation of low probability events (1% or less). This is because traditional models are based on the conditional normality assumption for financia
