单项选择题
An analyst does research about risk management applications of option strategies. With respect to option strategies, the shape of the graph that illustrates both the value at expiration and profit for buying a call is most similar in shape to the graph for:
A. selling a put.
B. a covered call position.
C. a protective put position.
答案
参考答案：C
解析： 有保护的看跌期权(protective put position)是购买一股股票的同时再买入针对该股票的一个看跌期权，当股票价格上涨时股票可以获利，看跌期权没有价值；而如果股票价格下跌股票损失时，看跌期权则可以获利，所以从图形上来看其收益类似于购买了一个看 涨期权。
