sample 里的 question 14: 正确答案是不是写错了。我觉得应该选a. currency risk can be hedged away ( curriculum v3, p367)
question 15。 答案是不是也错了? 答案给了c,但是计算结果是b. 是不是应该选b?
question 16. c 为什么不对呢?
14题我觉得是题目出错了,a是错的,b也是错的,currency risk不能被net across all portfolios. Only part of currency risk can be diversified away. c应该是对的啊,书上写了,contribution of currency risk decreases with the length of investment horizon.
