单项选择题
Jimmy Casteel pays a premium of $1.60 to buy a put option with a strike price of $145. If the stock price at expiration is $128, Casteel's profit or loss from the options position is:
A．
| A. $18.40. |
B．
| B. $1.60. |
C．
| C. $15.40. |
答案
参考答案：C
解析：The put option will be exercised and has a value of $145 - $128 = $17 [Max (0, X -S) ]. Therefore, Casteel receives $17 minus the $1.60 paid to buy the option. Therefore, the profit is $15.40 ( $17 less $1.60).
