QuestionA stop-buy order is most likely placed when a trader:选项：
A.wants to limit the loss on a short position.
B.thinks that the stock is overvalued.
C.wants to limit the loss on a long position.
解释：
SolutionA is correct. A trader who has entered into a short sale will incur losses if the stock price begins to increase. A stop-buy order helps limit the loss on a short position because it becomes valid for execution when the stock price rises above the specified stop price.
B is incorrect. A stop-buy order is beneficial when the stock is undervalued (not overvalued) but the trader is unwilling to trade without market confirmation.
C is incorrect. A stop-sell order is appropriate when the trader holds a long position, not short position. A stop-sell order becomes valid when the stock price falls.
