单项选择题
A stop is used to trigger a buy or sell order when the stock price reaches a specified price:（）
A. but does not guarantee that the order is completed at the stop price.
B. but is only triggered if the order can be completed at the stop price.
C. but only after the seller receives written or verbal notification from the selling broker.
答案
参考答案：A
解析：
A stop order is roughly the opposite of the limit order. A market buy order is triggered if the price goes above the specified price (also called the limit price), while a market sell order is triggered if the price goes below the limit. Since the trigger of the stop order generates a market order, the price is not guaranteed.
