We can consider the closing prices as a vanity metric to measure returns. But, what if the stock price became affected by some event that moved the prices dramatically toward a stock trade closure? The calculated historical returns may not consider the effects of such events and it may or may not also reflect in the next day’s closing price.

Therefore to better accurately calculate the returns during such situations, we consider using the Adjusted Closing Price.

In simple terms, we can describe the Adjusted Closing Price as a price adjustment made in the closing price of a stock. Hence, you can consider the closing price as just a mathematical number calculated using the total trades made in the final 30 minutes before closing the market. It is just a component of cash metrics. Thus, does not alter the effect of any corporate announcement.

How to Calculate a Stock’s Adjusted Closing Price

As earlier mentioned, we often use the adjusted closing price when evaluating historical returns or conducting a detailed analysis of historical returns.

Whenever a company carries out distributions, it becomes simple to calculate the adjusted closing price. For cash dividends (Profits), we divide the value of the dividend from the last closing sale price of the stock.

For instance, let’s speculate that the closing price for one share of ABC Corp. is $30 on Thursday. After the close on Thursday, ABC Corp. announces a dividend distribution of $2.50 per share. The adjusted closing price for the stock will then be $27.50 ($30-$2.50).

However, if ABC Corp. announces a 3:1 stock dividend rather than a cash dividend, the adjusted closing price calculation will change. A 3:1 stock dividend means that for every share an investor owns, he or she will receive three more shares. In this case, the adjusted closing price calculation will be $30*(1 / (3+1)). This will give you a price of $7.50, rounded to the closest penny.

While if ABC Corp. announces a 3:1 stock split, investors will receive an extra share for every share they already own. This time the calculation will be $30*(1 / (1×3)), indicating an adjusted closing price of approximately $10.

What Are The Benefits Of Adjusted Closing Price?

We have elaborated on some advantages of using the Adjusted Closing Price. They include;

#1. Accurate Returns

The major advantage of using an Adjusted Closing Price is to evaluate returns. It seems difficult to interpret the actual returns based on the closing price.

For example, decent companies keep splitting shares, which influences the graph of returns. If a company splits its shares, it doesn’t entail that an investor loses half of his money. In such cases, a difference, hence Adjusted Closing Price is a better metric to measure returns.

#2. Compares against asset classes

Adjusted Closing Price also helps in comparing the returns of long-term investments for two or more asset classes. The closing price doesn’t express the dividend payments, which will decrease the profitability while calculating the returns.

Therefore, if you use the Adjusted Closing Price it will give you a better picture for calculating returns on investment and handling the effects of major events if any.

What Is a Stock Split?

A stock split involves a situation where a company lowers its share price by splitting existing shares into multiple shares. Companies often do this (split stocks) to make share prices/value more affordable for individual investors. Meanwhile, note that a stock split does not affect the market capitalization or the value of all the company’s outstanding shares.

For instance, let’s say a company’s shares sell for $50 and they undergo a 3:1 stock split. You’d use the split ratio, which is 3:1 in this case, to determine the adjusted closing value. You’d divide the $50 share price by 3 and multiply by 1 to get the adjusted closing value. If you owned a $50 share, you would own two $25 shares. The stock’s closing price would be $50, while its adjusted closing price would be $50.
