题目
Which of the following barrier put options is best described as a standard put option that ceases to exist if the underlying asset price hits a barrier level, which is set above the current stock value?
选项
A.Up-and-in put
B.Up-and-out put
C.Down-and-in put
D.Down-and-out put
答案
B
解析
An up-and-out put is a standard put option that only ceases to exist if the underlying asset price hits a barrier level, which is set above the current stock value. The opposite situation would be an up-and-in put, which only comes into existence if the underlying asset price hits the barrier level.向上敲出看跌期权是一种标准看跌期权，只有当标的资产价格触及高于当前股票价值的障碍水平时才会失效。相反的情况是买入看跌期权，只有当标的资产价格触及障碍水平时才会出现这种情况。
