问题如下：
Determine the value at expiration and the profit for a buyer if the price of the underlying at expiration is $55.
选项：
A.$5
B.$1
C.–$1
解释：
B is correct.
CT = Max(0,ST – X) = Max(0,55 – 50) = 5 Π = CT – C0 = 5 – 4 = 1
中文解析：
根据公式CT = Max(0,ST – X) = Max(0,55 – 50) = 5 Π = CT – C0 = 5 – 4 = 1计算即可，注意求profit需要减掉期权费。
“Determine the value at expiration and the profit ”问题到底问的是value还是profit呀
