问题如下：
A trader who has bought a stock at $30 is concerned about a downside movement in the stock and would like to place an order that guarantees selling it at $25. Which of the following will most likely help the trader achieve her objective? (GTC = Good-till-cancelled)
选项：
A.“GTC, stop 25, market sell” order
“GTC, stop 25, limit 25 sell” order
“long put option” market order with a strike price of 25
解释：
Option contracts can be viewed as limit orders for which execution is guaranteed at the strike price. Therefore, a “long put” order at a strike price of 25 will guarantee selling the stock at 25.
如果是这样的话 是不是价格跌到25激活条款，20价格的时候开始卖
最高损失（买入价格是30的话）就是30-20=10，那如果股价跌的太快直接跌穿25，直接到20了，那损失不就30-20=10了，没有 最大损失一说了。
