问一道题:NO.PZ2015122801000057

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.

看了老师的回答,对于stop buy和limit buy还是有点疑惑,比如现价价格是10

stop buy指的是我预测价格会上涨,所以,我能接受的价格是12,那么,只要价格到12我就买入,涨到11的时候我都不买

limit buy指的我能接受的最高价格是12,如果涨到11,我也买了

是这个意思吗

Gail shoulestablish a stop buy 98 because this orr will executeonly if the stopririses to 98.C是正确的。本题考察的是股票交易术语的区别。Stop buy(停止买入) 和 limit buy(限价买入)的最大区别是前者是一个有效性指令,而后者是一个限定成交价的指令. Stop buy是大于等于某股价成交;limit buy是小于等于某股价成交。Stop buy意味着只要比该指令定的价格高,就要买入。在本题中,Astri空股票时的市场价格是95美金,如果用stop buy $80指令,由于市场价远高于80,指令会立即生效,则Astri刻被平仓,就达不到要的效果了。如果用limit buy,则意味这只有到达80这个股价(小于等于),才会平仓,这才满足Astri要求。所以A,B都是错误的。Limit buy同理,如果用limit buy 来实现Gail的愿望,当前股价86美金,那成交的就会是84美金到98美金之间的单,显然不符合Gail的要求。而stop buy是大于98才成交。C正确。 请问84美金(解析)是哪里来的数字?谢谢
