问题如下：

Caroline Rogers believes the price of Gamma Corp. stock will go down in the near future. She has decided to sell short 200 shares of Gamma Corp. at the current market price of €47. The initial margin requirement is 40%. Which of the following is an appropriate statement regarding the margin requirement that Rogers is subject to on this short sale?

选项：

A.

She will need to contribute €3,760 as margin

B.

She will need to contribute €5,640 as margin

C.

She will only need to leave the proceeds from the short sale as deposit and does not need to contribute any additional funds

解释：

She will need to contribute €3,760 as margin. Initial margin is the money that must be deposited in a futures account before any trading takes place. Before trading, She must deposit €3,760 = 40% of €9,400 (€9,400 = 200 X €47) as the initial margin.

同学你好，但是股票价格不仅会下跌，也会上涨，且投资者或任何一个人都无法100%确定股价一定会跌或一定会涨

而这个保证金就是如果一旦股票没有下跌而是上涨了，那投资者就开始亏损，券商作为借出股票的人，就有必要要求一定的保证金保证这种情况下保证金可以覆盖这些亏损，避免股票涨价后无法按市场价买回从而券商自己发生损失

Sell short 是什么意思呢？是卖出一个卖空short put option的意思吗？
