NO.PZ201702190100000102 问题如下 Whiof the following options strategies is Ferrell most likely to recommenfor the client’s portfolio? A.Long calls B.Short calls C.Short puts B is correct.inx-tracking portfolio without options ha lta of 1. To achieve a lta of 0.9, the lta of the options position must negative. Of the three choices, only short calls have a negative ltLong call options have ltranging from 0 to 1. Short calls, therefore, have ltranging from 0 to -1. The short call position lowers the portfolio’s overall lta sire考点 Sensitivity Risk Measures解析option 用lta衡量风险,正如股票通常用 β ,债券通常用ration convexity衡量。lta的定义是期权价格变化 / 标的物资产的价格变化,对于call option,标的物资产价格增加,期权价格越高,所以long call option的lta为正。short call option的lta为负。同理,long put option的lta为负,short put option的lta为正。具体内容在二级衍生这门学科还会学到。 inx-tracking portfolio without options ha lta of 1因为价格变1个单位 portfolio value就变1个单位?

NO.PZ201702190100000102 不太理解题目的,这个题目客户风险承受力弱,是需要降低风险敞口的,但lta的判断不太明白
老师这个是coverecall的操作吧?因为年龄大,所以担心下跌,应该控制风险,在持有了股票的同时,再short call,可以降低股票下跌带来的冲击。这里考的有点过于衍生品了吧?既与实际相挂钩,还要知道lta的变化和option的关系。。。真题不会跨着学科这么变态吧
老师好,为什么从这句 ask him to make the lta to 0.9 可以看出 题是要我们降低lt谢谢
