Abstract in Portuguese
A análise de estilo baseada em retornos é um método quantitativo que permite um melhor entendimento sobre o estilo de gestão dos fundos de investimentos. Este método compara os retornos históricos do fundo em estudo com os retornos de índices passivos de mercado, os quais funcionam como indicadores de estilo do fundo. Os pesos de cada índice de mercado dentro da carteira analisada são obtidos através de programação quadrática por causa de restrições de desigualdade. Como os testes estatísticos tradicionais não podem ser aplicados neste caso, foram desenvolvidos métodos alternativos para verificar a significância dos coeficientes estimados. Estes métodos envolvem tanto a derivação da estatística t aproximada quanto a distribuição assintótica obtida por meio da técnica de bootstraping. Por fim, a metodologia e os testes acima descritos são aplicados a uma amostra de fundos de investimentos brasileiros.

Abstract in English
Return-based style analysis is a quantitative method which allows a better understanding of the management style of investment funds. This method compares historical retums from funds with returns from passive market indexes, which work as style indicators. Because of inequality constraints, the weights of each market index inside the portfolio are obtained through quadratic programming. Traditional statistical tests can not be applied in this case; therefore alternative methods to check the statistical relevance of the estimated coeffícients were developed. These methods are an approximated derivation of the t-statistics and an asymptotic distribution of the coeffícients by the use of bootstrapping method. Finally, the methodology and the tests above described are applied to a sample of Brazilian investment funds.
