A trader holds a 1-year American put option with a strike price of USD 100 on a stock currently trading at USD 85. To value the option, a one-stop binomial tree is used where the stock price can move up or down by USD 10 in the 1-year period. If the risk-neutral probability of the stock moving up is 81% and the risk free rate is 6% per year. What is the current value of the American put?
选项:
A.USD 8.29
B.USD 15.00
C.USD 17.01
D.USD 19.97
解释:
由于是美式期权,可以提前行权,提前行权后可以获得100-85=15元
15>8.29,因此选择提前行权
