为何这道题的答案是pre-trade呢?

Although focused on long-term value, North Circle Advisors will exploit temporary mispricings to open positions. For example, portfolio manager Bill Bradley pegged LIM Corporation’s fair value per share at $28 yesterday; however, LIM’s stock price seems to have overreacted to a competitor announcement prior to market open today. The follow events unfold over the course of the morning:

  • PRIOR CLOSE: LIM closed at $30.05
  • PRE-MARKET: LIM priced at $20.34
  • MARKET OPEN: LIM opens at $22.15
  • 10:00 AM: LIM trading at $23.01
  • 10:00 AM: Bradley confirms the overreaction with target price of $28
  • 10:05 AM: Bradley instructs trader to buy 25,000 shares, with a limit price of $28 when LIM is trading at $23.09
  • 10:22 AM: Trader finishes the buy with an average purchase price of $23.45

Bradley and the trader conduct a post-trade evaluation. In picking an appropriate reference price, the trader asks Bradley if that would be a pre-trade, intraday, post-trade, or price target benchmark.

同学你好:

题目中给出的这些价格数据都是pre-trade benchmark。参考基础班讲义P29页。

arrival price是23.09,decision price是23.01,我是通过排除法反推出来的。target price和limit price都是干扰项,由于arrival price和decision price都针对的是市场价格,因此和我们交易时设定的target price和limit price无关。剩下来就只有23.01和23.09了,因此反推出decision是23.01,arrival price是23.09.

这道题出的不是很好,关键价格信息的表述都不是很清楚,不是精确的定义表达。官网的习题,都来自于一个题库,出的比较乱的,还是建议优先选择原版书课后题。
