You can calculate net change by using the following steps:

Step 1: Firstly, determine the Closing price at the end of the period for which the analysis is conducted.

Step 3: Finally, deducting the values arrived in step 2 from step 1.

Net Change Formula = Current Period’s Closing Price – Previous Period’s Closing Price

Step 4: Also, if a net change is to be calculated in percentage terms, than the values arrived in step 3 is divided with step 2 values.

Net Change (%) = [(Current Period’s Closing Price – Previous Period’s Closing Price) / Previous Period’s Closing Price]*100

Example #1 – Positive Net Change

Let’s take an example of the prices of the stock of a company AB. At the end of the current session, the prices of the stock closed at $50.55. The stock prices of the same company closed at $49.50 at the end of the prior trading session. What is the net change in the company’s stock prices during the period?

Solution:

Use the given data for the calculation of net change.

Net Change Formula Example 1

Calculation of net change can be done as follows:

Example 1.1.0

Net Change = $50.55 – $49.50

Net Change will be –

Net Change Formula Example 1.2

Net Change = $1.05

Thus the net change in the stock price from prior trading session end to a current trading session at is $1.05.

Example #2 – Negative Net Change

Let’s take another example of the prices of a company’s stock, Info ltd. The prices of the company’s stock at the end of the current session closed at $150.00, but the prices of the same company closed at $165.50 at the end of the prior trading session. What is the net change in the company’s stock prices during the period?

Solution:

Use the given data for the calculation of net change.

Example 2

Calculation of net change can be done as follows:

Net Change Formula Example 2.2.0

Since the prior trading session price was greater than that of the current session’s closing price, there will be a negative net change in the stock prices of the company during the period.

Net Change = $150.00- $165.50

Net Change will be –

Net Change Formula Example 2.3.0

Net Change = -$15.50

Thus the net change in the stock price from the prior trading session end to the current trading session is -$15.50.

Example #3

Let’s take another example of a company. One of the technical analysts wants to research the prices of the stock of the company. He wants to know the value of the change in the company’s prices after one month. For this, he got the following information:

  • Current session’s closing price of the stock of the company: $1,100
  • Prior session’s closing price of the stock of the company (one month before): $1,000

What is the net change in the prices of the stock of the company during the period in value and in percentage terms?

Solution:

Calculation of net change can be done as follows:

Net Change Formula Example 3

Net Change = $1,100- $1,000

Net Change will be –

Example 3.1

Net Change = $100

Calculation of Net change (%) can be done as follows:

Net Change Formula Example 3.2

Net Change (%) = [($1,100 – $1,000) / $1,000] * 100

Net Change (%) will be –
