老師,密卷下午提item set 4最后一問,為什么comment 2錯,comment 3對?1. long-short equity不是可以reduce beta risk, 那說shorting can increase active risk不就錯了嗎?2. long-short equity還可以增加potential alpha, 那market return premium應該也是增加?——以上我哪里理解錯了呢?
Q33: 書中18章exhibit 3 那張表的解釋了里提到alive cap tilt。請問為什么是large cap tilt? In Exhibit 3, we show the sources of performance of each product in terms of its exposure to each of the four factors and its respective alpha. In all cases, the Market factor is the dominant source of performance. The Value and Momentum factors did contribute positively to performance for the Russell 1000 Value, but much of this performance was lost because of the large-cap tilt and the negative alpha. The value fund did get a significant performance boost from the Value tilt, but much of it was lost to the very poor alpha in this period.” Excerpt From 2022 CFA Program Level III Volume 3 Fixed Income and Equity Portfolio Management CFA Institute This material may be protected by copyright.
