问题1,为什么benchmark也会有Alpha?
问题2,如何看出“the excess return was achieved largely through a very high and intentional exposure to rewarded factors”以及“the excess performance is so strongly explained by exposure to specific factors”?
问题3,“tracking error is a concern, it is important to identify satellite managers whose active returns have a low correlation with the core mandate, perhaps even a lower active risk”,这句话的意思是不是说,Tracking Error是因为return low correlation和risk low correlation?
