Mutual funds in shares in Brazil: performance and expertise management / Fundos de investimento em aÃÃes no Brasil: performance e expertise de gestÃo

Artur Eduardo da Nave e Castro 01 December 2010 (has links)
nÃo hà / This article analyzes the Brazilian stock mutual funds market, proposing dynamic rankings constructed from different risk-return performance metrics during the period from 1998 to 2009. We can evidence an unusual level of persistence, especially among the funds with better performance due to the expertise of managers. The quarterly rebalancing of portfolios based on these rankings allows us to infer that in scenarios characterized by economic boom, the equal weighted strategies in funds winners provide significant increases in average monthly earnings, risk reduction associated with diversification and consequent increase in performance in relation to market or sectoral benchmarks. This evidence is robust to the use of different performance metrics for the selection of funds, signaling that the shareholders of the winner funds require good performance not only in Sharpe, but also on other metrics, such as Treynor, Sortino and Calmar. In these optimistic scenarios, only the index of the industrial sector (INDX) provided values compatible with these portfolios of funds. However, in crisis scenarios, no strategy involving the funds can provide the levels characteristic of the hedging index of the electricity sector (IEE). It is possible to show that the majority of these strategies are dominated by the benchmarks on the riskreturn criteria, except for the value weighted portfolios composed by looser funds, a sign that the common shareholders of the big and passive funds may be experiencing higher levels of inertia. / Este artigo analisa o mercado de fundos de investimentos em aÃÃes no Brasil, propondo rankings dinÃmicos construÃdos a partir de diferentes mÃtricas de performances risco-retorno, durante o perÃodo de 1998 a 2009. à possÃvel evidenciar um nÃvel de persistÃncia incomum, principalmente dentre os fundos com melhor performance devido à expertise dos gestores. O rebalanceamento quadrimestral de portfolios com base nestes rankings permite inferir que em cenÃrios caracterizados por boom econÃmico ou recuperaÃÃo dos mercados financeiros, as estratÃgias com participaÃÃes iguais em fundos winners proporcionam aumentos significativos de ganhos mÃdios mensais, reduÃÃo de risco associado à diversificaÃÃo e consequente aumento de performance em relaÃÃo a benchmarks de mercado ou setoriais. Esta evidÃncia à robusta ao uso de diferentes mÃtricas de performance para seleÃÃo dos fundos, sinalizando que os cotistas dos fundos winners ativos exigem boa performance nÃo somente em Sharpe, mas tambÃm em outras mÃtricas, tais como os Ãndices de Treynor, Calmar e Sortino. Nestes cenÃrios otimistas, apenas o Ãndice do setor industrial (INDX) proporcionou valores compatÃveis aos destes portfolios de fundos. PorÃm, em cenÃrios de crise, nenhuma estratÃgia envolvendo os fundos consegue proporcionar os nÃveis de hedge caracterÃsticos do Ãndice do setor de energia elÃtrica (IEE), sendo possÃvel evidenciar que a maioria destas estratÃgias à dominada nos critÃrios de ganho-risco por Ãndices setorias ou de mercado, com exceÃÃo dos portfolios value weighted compostos por fundos loosers, um sinal de que os cotistas usuais dos grandes fundos passivos e indexados ao Ibovespa podem estar apresentando maior nÃvel de inÃrcia.
