卖出看跌期权的要求

NO.PZ2019012201000008

问题如下:

Which of the following statements about securities lending and covered call writing is incorrect?

Statement 1 Securities lending would increase income through reinvestment of the cash collateral but would require the fund to miss out on dividend income from the lent securities.

Statement 2 Writing covered calls would generate income, but doing so it requires portfolio manager simultaneously deposits money equal to the exercise price into a designated account.

选项:

A.

Only Statement 1

B.

Only Statement 2

C.

Both Statement 1 and Statement 2

解释:

C is correct.

考点:Income in an equity portfolio

解析:表述1是错误的,因为出借股票的股利是由股票借款人为股票出借人"制造"的——也就是说,股票借款人要确保股票出借人在没有出借股票的情况下获得的股利得到了补偿。因此,表述一是不正确的。

表述2也是错误的,因为需要将与行权价格相等的款项存入指定账户,这是卖出看跌期权的要求,而不是卖出看涨期权需要做的。

需要将与行权价格相等的款项存入指定账户,这是卖出看跌期权的要求。请问老师,卖出看跌必须要将与行权价格相等的款项存入指定账户,还是该存款可有可无。

嗨,爱思考的PZer你好:

在CFA这里,卖出期权,是义务的一方。因此要求把款项存入指定账户。

如果不提前准备款项,就容易造成违约。

就好像现实中,向别人借钱,需要给别人抵押物,否则就很容易借钱不还。


不过现实中,做空期权一般会要求一个保证金,不会要求把全额款项存入指定账户。
