2020-07-22 10:59請(qǐng)問(wèn)在reading 25 中 example 10, 第一個(gè)問(wèn)題中,Information ratio = Active return / Active risk. 如果 active return 越高 active risk 不會(huì)也會(huì)增加嗎? 另外,"Adding the ability to short could facilitate a more balanced distribution of risk. Given the similar volatilities and low cross correlations among factors, the more balanced distribution of risk can be expected to reduce the tracking error of the strategy, thereby improving the information ratio." 如何在降低 tracking error 的狀況下提升return呢? 如果 portfolio return 高於 benchmark return,那tracking error應(yīng)該也會(huì)增加吧?

同學(xué)你好!
注意搞清楚概念。Active return is defined as the portfolio return minus the benchmark return;Active risk is the annualized standard deviation of active returns。
回到你的問(wèn)題:
1.active return高,不一定active risk高,只需要active return的波動(dòng)小就行;
2.tracking error即 active risk,比如一個(gè)因子原來(lái)給組合帶來(lái)穩(wěn)定的負(fù)收益,short以后,就是帶來(lái)穩(wěn)定的正收益,那么此時(shí)return增加,但active risk不一定變大。
3.和第一問(wèn)一樣的意思,見(jiàn)1。
