Avaliação do desempenho de fundos de investimento tecnológicos

Abstract

Esta dissertação pretende avaliar o desempenho de fundos de investimento tecnológicos americanos. Neste estudo são analisados todos os fundos de investimento tecnológicos do mercado norte-americano existentes entre janeiro de 2000 e março de 2010, que existiram durante pelo menos três anos. Como metodologias de avaliação do desempenho são usados quer modelos não condicionais, quer modelos que têm em conta a informação disponível acerca do estado da economia na previsão do risco e da rendibilidade esperada. A partir do estudo é possível concluir que os gestores destes fundos não conseguem superar o mercado e há evidência de betas condicionais, mas não se encontram alfas condicionais. Neste estudo é também avaliado o impacto do survivorship bias nas estimativas de desempenho, tendo-se observado que a sua magnitude é significativa no contexto dos modelos multifatores.
