老师，请问价格从25.22涨到25.26不算market impact吗

问题如下：

Johnson discusses a market buy order for 5,000 shares of an illiquid stock. The order was filled in three trades, and details about the three trades are presented in Exhibit 2.

Based on Exhibit 2, the market impact relating to Trade 2, on a per share basis, is closest to:

选项：

A.

$0.02.

B.

$0.03.

C.

$0.07.

解释：

A is correct. Market impact, or price impact, is the effect of a trade on transaction prices. After the first trade (Trade 1) was executed at $25.20, Trade 2 was executed at $25.22, which is $0.02 per share higher than the trade price of Trade 1. So, the execution of Trade 1 led to a price impact of $0.02 per share on Trade 2.
