assume that inefficiencies exist that may be exploited to earn positive return after adjusting for beta risk 这句话怎么理解?
The performance benchmark selection process is another area where misrepresentations may occur. 这句话怎么理解?
看到老师回答别的同学的问题,我也有疑问,long call行权是增加duration,long put行权是减少duration。但short call行权应该是减少duration,相当于持有的资产强制被卖出;short put是被强制去买入,增加duration。和老师说的不一样呢。所以对应到百题固收case3 Q3这里covered call存在的问题是,虽然它被行权后能够减少duration,但因为这里rate上升price下降,实际上无法行权,才无法发挥covered call减少duration的作用。实际上long/short call/put都存在这个问题,他们都能调整duration但只有在被行权的情况下才能发挥作用。
