Adjusted Close Price Explained

Adjusted close price is a financial concept used in the stock market to account for various corporate actions that can impact a stock's value. When a company undergoes events like stock splits, dividends, or rights offerings, the stock's price can be significantly altered. To maintain the continuity of historical data and provide a more accurate representation of the stock's performance, the adjusted close price is calculated.

The calculation involves adjusting the stock's closing price on each relevant date, considering the effect of the corporate action. This adjustment factor is then applied to all previous closing prices to ensure that the historical data reflects the stock's true value as if those actions had not occurred.

Investors and analysts heavily rely on adjusted close prices to make informed decisions and conduct meaningful analyses. By eliminating distortions caused by corporate actions, this metric allows for a more precise evaluation of a stock's performance over time and facilitates fair comparisons between stocks and periods. This modification ensures that historical price data remains accurate and comparable, allowing investors to analyze stock performance over time without distortions caused by these events.

How To Calculate?

To calculate the adjusted close price for a stock, follow these general steps:

Gather historical price data, including closing prices and dates, for the stock of interest.
Account for stock splits during the period, and divide all closing prices before the split date by the split ratio.
Subtract the dividend amount from the closing price on the ex-dividend date. The ex-dividend date is when the stock starts trading without the value of the upcoming dividend.
Consider other corporate actions. If other events like rights offerings or mergers exist, adjust the closing prices accordingly.
After making all the necessary adjustments, one will have the adjusted closing prices for each date.

Examples

Let us have a look at the examples to understand the concept better.

Example #1

Let us consider a calculation example to arrive at an adjusted closing price. Below is the data of a stock name XYZ

Below given are the dates & historical closing prices:

Jan 1: $100.00, Jan 2: $105.00, Jan 3: $98.00, Jan 4: $102.00

Stock Split: On Jan 2, Company XYZ underwent a 2-for-1 stock split.
Dividend: On Jan 3, the company paid a dividend of $2.00 per share.
Adjusted close price calculation:

Adjust for the stock split on Jan 2: The closing price of $105.00 becomes $105.00 / 2 = $52.50.

Adjust for the dividend on Jan 3: The closing price of $98.00 becomes $98.00 - $2.00 = $96.00.

Below are given the dates and adjusted close price:

Jan 1: $100.00, Jan 2: $52.50, Jan 3: $96.00, Jan 4: $102.00

Example #2

Consider a company called 'TechCore Inc.' which is publicly traded on the stock market. Over time, TechCore's stock price fluctuates due to various factors like market conditions, company performance, and corporate actions. The closing price at the end of each trading day reflects the stock's value at that moment. The company regularly pays dividends to its shareholders based on its profits.

Sometimes, the company might issue additional shares to existing shareholders instead of cash dividends. This action increases the number of outstanding shares, potentially impacting the stock's price.

To account for such corporate actions, the 'adjusted closing price' concept comes into play. It provides a modified value of the stock's closing price, considering the effects of dividends, stock splits, or other significant events. By using adjusted closing prices, investors can accurately analyze the stock's performance over time, considering the impact of these actions on its value.
