标题: American Option [打印本页] 作者: Spongebob 时间: 2011-7-13 16:35 标题: American Option
Which of the following statements about the early exercise of an option is least accurate? For an American:
A) call option, on an asset with no cash flows, early exercise can be profitable if the option is far in the money.
B) put option on an asset with no cash flows, early exercise is sometimes optimal.
C) call option on an asset with positive cash flows, early exercise is sometimes profitable.
Your answer: C was incorrect. The correct answer was A) call option, on an asset with no cash flows, early exercise can be profitable if the option is far in the money.
Early exercise of an American call option on an asset with no cash flows is never profitable, they are worth more ‘alive than dead’.
Q: Anyone can explain?作者: joemoran 时间: 2011-7-13 16:35
You are holding a call option, meaning you have right to buy, meaning if you exercise now you have to part with your cash now.
If option is deep in the money, then it is better to exercise it later rather than now. That way you get to keep your cash longer and earn discount rate on it.
Always, other things same, it is better to
a) buy later rather than sooner
b) and sell sooner rather than later
Hope this helps.作者: bapswarrior 时间: 2011-7-13 16:35
I understand your comments, rus1bus.
I don't quite get the thing about "asset with no/positive CF". What is it trying to say? I only understand that if the asset has positive CF, the cost will be less by the PV of the CF.
Thanks.作者: manasib 时间: 2011-7-13 16:35
If asset has positive cash flows then you might want to buy it earlier, because it will then start to give you those cashflows. In this case, you will consider if positive cashflows from it could compensate for the loss of interest you could earn on keeping your cash and buying the asset later.
But if asset does not have any positive cash flows then there is no such consideration.作者: amqata 时间: 2011-7-13 16:35
I see.
A) call option, on an asset with no cash flows, early exercise can be profitable if the option is far in the money.
>> Since it is far in the money, can't I exercise it and sell the underlying immediately for a profit?作者: mnieman 时间: 2011-7-13 16:35
What if next weeks later it came out of money? It won't be profitable anymore.作者: kmf229 时间: 2011-7-13 16:35
Yes, that is very much a possibility.
But in the question, when it says 'far' in the money, they want us to assume, it will remain in the money till the strike date.作者: dece2011 时间: 2011-7-13 16:35

That is sad , but good thing is you are already focused, know exactly what you want to do and the best part is, you are actually ahead of it
