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.
這道題的答案和說明怎么不一致呢。。。

老師,你好。原版書課后題equity部分,reading 22的第7題,關(guān)于note4的表述:如果是被動投資,因為需要追蹤指數(shù),需要頻繁調(diào)倉,fees不是應該更高嗎?note5的表述,在投資組合中加入債券,因為債券相對equity風險低,降低短期風險,這個表述不是應該是正確的嗎?

老師好,視頻里股票帶來的收益那里secertities lending income沒聽懂,這里的lending income應該就是借出股票人的利息收入加上抵押品的投資收益吧?不包括做空賺的錢,因為做空賺的差價應該是借入股票人的收益,而不是借出股票人的收益吧?
P/B為什么是value proxy?高P/B應該是growth style吧?
