2. Up and out put, with barrier H = 100, striked at 100. Current stock price
50, no interest rate. what is the price?
Thanks! |
s********4 发帖数: 38 | 2 2. up and out, stock price到了100就没有payoff了,那这个put不是worthless么?
我的理解对么 |
b***n 发帖数: 6 | 3 如果stock price没到100的话,payoff就不是0啊

b*****d 发帖数: 7166 | 4 第一个stock价格要假设geometric Brownian motion或是其他分布吧,否则没法做。
借贴问一下,怎么搞到面试啊,我找到猎头一问visa基本就没信了。内推吗?
要是在公司网站上自己投吗? |
b***n 发帖数: 6 | 5 嗯对啊 应该假设GBM的 然后怎么解呢
觉得从学校的career center投简历更有效吧。

spend 1 dollar to buy 1/S0 share of stock, and it will be worth of 1/St
Price = 1/S0 |
p******i 发帖数: 1358 | 7 it becomes ST/S0 isn't it?
【在 m*****n 的大作中提到】 : 1st answer : spend 1 dollar to buy 1/S0 share of stock, and it will be worth of 1/St : Price = 1/S0

m*****n 发帖数: 3575 | 15 Let us change the currency
the dollar as underlying and the share as currency
at time T: $1=1/S(T) share
at time 0: $1=1/S(0) share
at time 0: $exp(-r*T)=exp(-r*T)/S(0) share
since $exp(-r*T) at time 0 is equivalent to $1 at time T
exp(-r*T)/S(0) share is equivalent to 1/S(T) share at time T
the initial value of payoff 1/S(T) share is exp(-r*T)/S(0) share
I know this is not satisfactory to someone who needs to know the initial
value of the payoff of 1/S(T) dollar. But I just figured out this yet. |
