老師好,這道題我沒有選C是因為如果是multi- factor manager,他偏向因子,那么他的idiosyncratic risk就小,為什么文中寫的是high active share呢?謝謝
老師,equity以下這兩點我很混淆:對于full replication來說,a large number of constituents會增大index的tracking error. 但是對于active share來說,the portfolio with the fewer securities and therefore higher degree of concentration in positions will have a higher level of Active Share,同時也會增大active risk。我覺得這兩點很矛盾。 Full replication :An index that contains a large number of constituents will tend to create higher tracking error than one with fewer constituents. The manager will naturally first purchase the largest, most liquid, lowest cost stocks. But as more stocks are added and the portfolio approaches full replication, the added stocks will be less liquid, increasing the effect of transaction costs on tracking error. 1) Comparison of active share If two portfolios with the same benchmark invest only in benchmark securities, the portfolio with the fewer securities and therefore higher degree of concentration in positions will have a higher level of Active Share.
