What Is the Closing Price?

The closing price is the point during an exchange's trading session at which the last price of the day is determined.

How it works

Like the opening price, the closing price is determined using the itayose method, which matches all the orders outstanding up to that point at a single price.

Difference from, and importance relative to, the opening price

The closing price serves as the reference for calculating the day's change and as the basis for the following day's price-limit range, and it is treated as "the stock's price for the day" in most financial news and charts. Unlike the opening price (see related page), which is set at the start of trading, the closing price is set at the end.

Frequently Asked Questions

How is the closing price used?
It serves as a base value in many contexts, such as calculating the percentage change from the previous day and setting the following day's price-limit range.
Why does the price often move around the close?
One reason often cited is that trades tied to the closing price — such as mutual fund NAV calculations or institutional investor rebalancing — tend to concentrate near the close. However, this is not the only factor at play.
