嗨,从没放弃的小努力你好:
不矛盾啊,请仔细看你说的强化班这一点是被动因子策略(新型的被动投资)和传统的主动投资相比。而这道题说就是一个传统的被动投资,传统的被动投资就是大盘买啥我也买啥,大盘不动我也不动,这样turn over 和rebalance都很少。而主动投资就是通过积极选股,经常的买卖来获得的收益的。注意要把咱们学过的内容套用在正确的题目中。
由于新型被动投资是有一定的主动决策在里面的即这些active成分,比如决定要投资哪些factor,weighting怎么设置之类的,这些是可以在既定benchmark基础上主动得做出决策做出一些调整,调整好了就passive tracking, 如果上述设定的权重发生变化就需要频繁的随着调整 。
我把原版书的原文给你放在这里供你参考下:Passive factor-based equity strategies use passive rules, but they frequently involve active decision making: Decisions on the timing and degree of factor exposure are beingmade. As Jacobs and Levy (2014) note, the difference between passive factor investing and conventional active management is that with the former, active management takes place up front rather than continuously.
