问题如下:
The return on an optimally hedged portfolio is independent of the return of the hedging instrument. True or false?
选项:
解释:
False. The optimally hedged portfolio is uncorrelated with the return on the hedge. It is not necessarily independent. It would be independent if the returns were jointly normally distributed.
hedge是做的线性对冲,所以对冲后只能保证optimally hedged portfolio与hedge instrument之间不存在线性关系,但可能存在非线性关系,所以不能说independent。
