老师,请问这个选哪个算法?

Beatrice Minchow designs and implements algorithmic trading strategies for Enlightenment Era Partners LLC (EEP). Minchow is working with Portfolio Manager James Bean on an algorithm to implement a sell order for Bean’s small position in the lightly-traded shares of public company Dynopax Inc. In a conversation with Minchow, Bean states the following:

  • I have no expectations of adverse price movements during the trade horizon and would like to use a scheduled algorithm.
  • I want to minimize market impact, but I’m more concerned about getting the sell order completely executed in one day.

Based on Bean’s comments, Minchow considers three algorithms: POV, VWAP, and TWAP.

同学你好:

这道题给出的两点信息,第一小点和第二小点的前半句话,三个算法都符合,都属于Scheduled,且均适用于no expectations of adverse price movements,适用于最小化市场冲击。 (参考基础班讲义P42页)

再来看第二小点的后半句话“but I’m more concerned about getting the sell order completely executed in one day.”,这句话可以将POV排除,因为POV的缺点就是未考虑能否买卖完全(参考基础班讲义P40页)。

至于如何区分是VWAP还是TWAP,题干并没有明确给出能够分辨他俩的信息,个人认为出题不严谨,只能做到排除POV,但不能得出确切的结论。

最后还是建议同学优先考虑做原版书课后题和我们的题库。Trading本身就是一门小学科,能掌握原版书课后题和老师上课讲解的内容足以应付考试。没有必要去做一些出的并不好的题目来扰乱我们正常的复习进度。
