Resumo: | This paper applies the traditional return-based style analysis (RBSA) in the presence of time-varying exposures. Often the investment style is assumed to be constant through time. Alternatively, time variation is sometimes implicitly accounted for by using rolling regressions when estimating the style analysis. We use the Kalman filter to model time-varying exposures of hedge funds explicitly. This leads to a testable model and more efficient use of the data, which reduces the influence of spurious correlation between hedge fund returns and style indices. The aim of this study is to estimate the investment styles and reveal periodic return distributions of Brazilian hedge funds for the 2006-2011 period. In a large sample of funds, we find substantial evidence that hedge fund risk exposures vary along the time. We also find that the exposition to fixed income is increasing over the last years. The results have shown that style analyses explain over 50% of the funds returns. Finally, we analyze exposures during the global financial crisis (2008-2009). |

Inicialmente, o modelo é estimado assumindo que os estilos são constantes ao longo do tempo. Posteriormente, é utilizada a abordagem do filtro de Kalman para modelar as exposições dos fundos multimercados variantes ao longo do tempo. Usando uma base de dados de fundos multimercados brasileiros, os resultados mostram que a RBSA pode explicar mais de 50% da variância dos retornos dos fundos. Também evidencia significante exposição ao mercado de ações e que a exposição a fatores relacionados ao mercado de renda fixa vem crescendo. Finalmente, a modelagem considerada capta mudanças importantes no estilo de exposição a fatores de risco dos fundos multimercados brasileiros decorrentes da recente crise financeira global (2008-2009).UFRGS2016-03-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufrgs.br/index.php/AnaliseEconomica/article/view/4577910.22456/2176-5456.45779Análise Econômica; Vol. 34 No. 65 (2016): março de 2016Análise Econômica; v. 34 n. 65 (2016): março de 20162176-54560102-9924reponame:Análise Econômica (Online)instname:Universidade Federal do Rio Grande do Sul (UFRGS)instacron:UFRGSporhttps://seer.ufrgs.br/index.php/AnaliseEconomica/article/view/45779/36639Copyright (c) 2019 Análise Econômicainfo:eu-repo/semantics/openAccessSchutt, Isabel GaioCaldeira, João Frois2016-05-06T16:24:32Zoai:seer.ufrgs.br:article/45779Revistahttps://seer.ufrgs.br/index.php/AnaliseEconomicaPUBhttps://seer.ufrgs.br/index.php/AnaliseEconomica/oai||rae@ufrgs.br2176-54560102-9924opendoar:2016-05-06T16:24:32Análise Econômica (Online) - Universidade Federal do Rio Grande do Sul (UFRGS)false |

We use the Kalman filter to model time-varying exposures of hedge funds explicitly.

The aim of this study is to estimate the investment styles and reveal periodic return distributions of Brazilian hedge funds for the 2006-2011 period.
