问题 单项选择题

一般而言,期权合约的时间价值、协定价格、标的资产市场价格三者之间的关系式是()。

A.协定价格与标的资产市场价格差距越大,时间价值就越小

B.协定价格与标的资产市场价格的差额,就等于时间价值

C.时间价值与标的资产市场价格差距越大,协定价格就越高

D.协定价格与时间价值差距越大,标的资产市场价格就越低

答案

参考答案:A

解析:一般而言,协定价格与市场价格间的差距越大,时间价值越小;反之,则时间价值越大。这是因为时间价值是市场参与者因预期标的物市场价格变动引起内在价值变动而愿意付出的代价。只有在协定价格与市场价格非常接近或为平价期权时,市场价格的变动才有可能增加期权的内在价值,从而使时间价值随之增大。

     Very often, new-born babies are not beautiful. They are wrinkled (多皱的) or hairless, or they have an

angry look on their faces. They seem to say, "Get away! I hate everybody." But to a parent, that hairless,

wrinkled, angry-faced baby is the most beautiful and perfect (完美的) child in the world. When that proud

father or mother asks you, "Well, what do you think … isn't she beautiful?" what are you going to say? Is this

the time for the truth? Of course not!

     When you look at that proud father, you should say, "Yes, she is! She's really a beauty. She's one in a

million. She's going to be a movie star! She's as beautiful as a picture."

     In English, this is a white lie. White lies don't hurt people. They are not cruel (残忍的) or angry words.

People use them to make a difficult thing a little easier. When people don't want to meet someone, or eat

something new that they really don't like at a friend's house, they tell a white lie. They are trying to be kind.

They feel that being kind is sometimes more important.
