“…With respect to market timing and selectivity abilities, none of the models used, including Jensen's alpha, Treynor-Mazuy (TM), and Henriksson and Merton (HM), yielded satisfactory results (Henriksson and Treynor apud Cassicia et al, 2011). The SI and TI confirmed the superiority of about half of the funds with respect to the benchmark, whereas TM and HM did not find this superiority, but reaffirmed that no evidence was found of timing by the managers (Casaccia et al, 2011).…”

“…Using a quantitative approach (resources, techniques, and statistical models), they listed a sample of funds. Using Sharpe's model, they found that 49% of the funds outperformed benchmarking; however, after performing the Jarque-Bera normality test, the results showed that 53% of the funds rejected the null hypothesis of normality, indicating that the results from the SI model may not have significance (the model has a premise of normally distributed returns) (Casaccia et al, 2011).…”

“…However, Casaccia, Galli, Macêdo, and Leitao (2011) did not identify any special abilities of managers in their sample. There are other studies on Brazilian funds using factor models where, in most cases, no superior managerial skills are evident.…”

“…O alfa de Jensen (1976), baseado também no modelo CAPM, corresponde ao termo independente (coeficiente linear) da Equação 14, necessário caso exista "uma parcela do retorno dos fundos independente da variação do excesso de retorno de mercado" (Ceretta & Milani, 2012, p. 97). Deste modo, o Alfa de Jensen "mede o excesso de retorno obtido pelo fundo após ajuste pelo risco sistemático, (dado pelo beta vezes o excesso de retorno do mercado)" (Varga, 2001, p. 9), ou seja, é o índice que obtém o diferencial de retorno quando a medida de risco utilizada é o beta (Casaccia et al, 2011), que pode ser obtido isolando o da Fórmula 14 resultando na seguinte Fórmula:…”
