Using two-period binomial model, Jack wants to calculate the terminal value of a put option. If the current price of the underlying asset is $150 and the strike price is $120, the size of an up move is 1.69 and a down move is 0.59. Only when the price is below the strike price can the option has a positive value, otherwise the value will be zero. How many terminal nodes can give back positive return?
选项:
A. 1
B. 2
C. 0
解释:
A is correct. Only the third node has a value less than $120, which is $52.22.
