问一道题:NO.PZ2020020202000013

问题如下:

The next day, Harding instructs Yellow to revisit their research on BYYP, Inc. Yellow’s research leads her to believe that its shares are undervalued. She shares her research with Harding, and at 10 a.m. he instructs her to buy 120,000 shares when the price is $40.00 using a limit order of $42.00.
The buy-side trader releases the order for market execution when the price is $40.50. The only fee is a commission of $0.02 per share. By the end of the trading day, 90,000 shares of the order had been purchased, and BYYP closes at $42.50. The trade was executed at an average price of $41.42. Details about the executed trades are presented in Exhibit 1.

Based on Exhibit 1, the opportunity cost for purchasing the 90,000 shares of BYYP is:

选项:

A.

$22,500.

B.

$60,000.

C.

$75,000.

解释:

C is correct.

Opportunity cost is based on the number of shares left unexecuted in the order and reflects the cost of not being able to execute all shares at the decision price. The opportunity cost is calculated as:
Opportunity cost = (SSj)(PnPd)(S-\sum S_j)(P_n-P_d)= (120,000 – 90,000) × ($42.50 – $40.00)
= $75,000

这是一个 limit order 为什么不是42-40,收盘价42.5是不会完成的吧

 opportunity cost就是拿(Pn-Pd)乘以未交易的股数,代表的是整个价格变动部分,由于没有交易一分钱都没有赚到的部分,这和限价指令的价格以及具体交易价格都没有关系。建议你回听一下基础班的例题或者原版书课后题。
