Unfortunately, these studies focus almost exclusively on alpha. In the present paper, we show the importance of considering not only the exposure to the market (the traditional beta), but also the other exposures (the alternative betas) to cover all the sources of hedge fund returns. To do so, we examine the real extent to which the variability and level of hedge fund returns are affected by (static) betas, dynamic betas (i.e., factor timing), and pure alpha (i.e., security selection).
