问一道题:NO.PZ2018062002000035

问题如下:

The following limit order standing in the stock’s order book:

Suppose Carl submitted a day order with a limit price of $ 20.87 and sold 1,000 shares, and no more investor submits a buy order after he submitted the order. What is the average price for Carl’s transaction?

选项:

A.

$21.70.

B.

$21.28.

C.

$21.05.

解释:

Carl’s average trade price is:

21.28=300×21.89+400×21.02+200×20.88300+400+20021.28=\frac{300\times21.89+400\times21.02+200\times20.88}{300+400+200}

Carl's order will be filled with the most aggressively priced buy order firstly, which is Fiona’s order for 300 shares at $21.89. Carl still remaining 700 shares did not sell. Philip’s order for 400 shares at $21.02 is the second aggressively priced buy order, after the order was filled Carl still have 300 shares to sell. Debbie’s order for 200 shares at $20.88 is the third aggressively priced buy order, he still has 100 shares to sell after the third order takes place. Liam’s order for 1,000 shares at $20.70 is the next buy order, but the price of this order is lower than Carl's required limit price, therefore, no more transactions can be carried out.

这个人出价低于买方报价,不是make a new market吗? 买方不是应该以他的价格成交吗?

1、报价在高于买价,低于卖价时才叫make a new market

2、他现在的卖价低于买价说明交易可以被执行,但是具体的成交价需要根据市场的报价及成交量计算(这道题就是在计算这个成交价)。

3、他的报价是以不能低于20.87的价格卖出,所以一切高于这个价格的买单都可以满足。卖价并不是就等于20.87。价高者优先买到。

答案没怎么看懂,可以解释下么?

maggie_品职助教 · 2020年03月12日

carl的报价是以不能低于20.87的价格卖出1000股,因此我们就看表格中当前bid报价就可以,四个报价中20.7低于20.87所以不满足报价,其它三个都高于20.87。所以carl最后只卖出的900股,它的平均卖价就是上面解析中计算的。

NO.PZ2018062002000035 老师上课举例说如果买方定了150块钱买,现在市场价10块,那成交价还是10块,不是150,这是为了防止市场波动,我还清楚记得这个例子和例子的数据。请问怎么理解老师讲的例子和这道题?不是矛盾吗?谢谢
