问题如下：
Astrid is short 400 shares of ABC stock and the stock's current price is $95 per share. She wants to cover her short position if the price falls to $80.
Gail has 250 shares of BBC stock, which is trading at $86 per share, and he needs to buy another 150 shares if the price rises to $98. What orders should Astrid and Gail establish to meet their targets?
选项：
A.Astrid establishes stop buy at $80 and Gail establishes limit buy at $98.
B.Astrid establishes stop buy at $95 and Gail establishes stop buy at $86.
C.Astrid establishes limit buy at $80 and Gail establishes stop buy at $98.
解释：
C is correct.
Astrid should establish a buy order with a limit at 80 because she wants to buy stock to close out her short position if she can buy it at 80(or less).
Gail should establish a stop buy at 98 because this order will be executed only if the stock price rises to 98.
有个疑惑：为什么感觉题目跟正常的思维是反的呢？协会考题是为了考，只管知识点逻辑，不管会不会发生吗？
例如：A是空头，为了cover her short position，空头标的下跌还要cover吗？cover不是说有亏损了，需要避险兜底吗？
题目逻辑不是跟之前讲的空头挣钱逻辑相违背吗？
