Resumo
With lhe increase of lhe number of assei managers and an even larger a number of investments alternatives in lhe Brazilian hedge fund industry, Fund of Hedge Funds became an alternative for investors planning to diversify their investments through financiai specialists. The intention of this study is to evaluate lhe capacity of Brazilian Funds of Hedge Funds (FoHF), classified as Multimercados Multigestor, to generate abnormal returns (alpha). For this porpoise we studied a sample of 1421 Fund of Hedg Funds between January of 2005 and December of 2011. The results of multi-factor model regressions, derived from Jensen's model (1968), suggest that only 3.03% of lhe funds in lhe sample can add value. The three main potential sources of alpha generalion in Funds of Hedge Funds come from lhe strategic allocation of lhe portfolios, lhe anticipation of market movements (market timing) and lhe capacity of FoHF managers to select lhe best assei managers in lhe industry to com pose its portfolio (fund selection). To evaluate lhe Brazilian FoHF manager's ability to anticipate market movements we included quadratic terms in lhe multi-factor models, as proposed by Treynor and Mazuy (1966). The results showed lha! managers, on average, could not add value by market timing. To evaluate lhe strategic allocation ability and lhe fund's selection abilities, we created a new variable with lhe information about lhe asseis in lhe porlfolio of each fund in lhe sample in every different month. The tests indicated that FoHF managers, on average, could no! add value by selecting lhe best managers, but lhe strategic allocation ability showed a positive contribution to FoHF's return. We also studied lhe alpha generation capacity before costs. lt raised lhe percentage of funds with positive alpha to 6.39% of lhe funds in lhe sample, but it was no! able to change lhe signal of lhe average alpha, lha! remained nega tive.
