题5 Research has revealed that the performance of professional money manager tends to be:
A. equal to the performance of a passive investment strategy
B. Inferior to the performance of a passive investment strategy
C. superior to the performance of a passive investment strategy
答案为B 不解
原因:之前有说到Weak semi-strong, strong form EMH 只有当strong form 情况下Professional Management 无用。其余都有用,即使在strong form 情况下 portfolio managers 也能add value by assisting with portfolio diversification 或者asset allocation...
为什么题目臆断Money manager 的Performance一定差于Passive investment strategy(被动持有)呢?
跪求各位大大解释
