Moving Average

What is Moving Average?

Moving Average (MA), commonly used in capital markets, can be defined as a succession of mean that is derived from a successive period of numbers or values and the same would be calculated continually as the new data is available. This can be lagging or trend-following indicator as this would be based on previous numbers.

Moving Average Formula

Moving Average = C1 + C2 + C3…. Cn / N

  • C1, C2…. Cn stands for the closing numbers, prices, or balances.
  • N stands for the number of periods for which average is required to be calculated.


Moving average is a type of arithmetic average. The only difference here is that it uses only closing numbers, whether it is stock prices or balances of account etc. The first step is to gather the data of the closing numbers and then divide that number by for the period in question, which could be from day 1 to day 30 etc. There is also another calculation, which is an exponential moving average; however, we have discussed here only a simple equation.

Example #1

Stock X was trading at 150, 155, 142, 133, 162, for the previous five trading days. Based on the given numbers, you are required to calculate the moving average.


Use the following data for calculation

Stock Closing Prices
Day 1150
Day 2155
Day 3142
Day 4133
Day 5162

MA can be calculated using the above formula as,

Moving Average Formula Example 1.1png
  • (150+155+142+133+162)/5

The moving Average for the trending five days will be –

Moving Average Formula Example 1.2png
  • = 148.40

The MA for the five days for the stock X is 148.40

Now, to calculate the MA for the 6th day, we need to exclude 150 and include 159.

Example 1.3png

Therefore, Moving Average = ( 155 + 142 + 133 + 162 + 159 ) / 5 = 150.20 and we can continue doing this.

Example #2

Alpha Inc was incorporated as Bank last year, and now its almost year-end to report the financial statement of the firmFinancial Statement Of The FirmFinancial statements are written reports prepared by a company's management to present the company's financial affairs over a given period (quarter, six monthly or yearly). These statements, which include the Balance Sheet, Income Statement, Cash Flows, and Shareholders Equity Statement, must be prepared in accordance with prescribed and standardized accounting standards to ensure uniformity in reporting at all more. The norms of the central bank asked the banks to report the average balances of the account instead of closing balance as at the end of the year. The average balances should be done on a monthly basis. The financial analyst of the firm took a sample account #187, where below were the closing balances reported.

Example 2

Based on the above closing balances, you are required to calculate a simple moving average.


First, in this, we will calculate the sum of the closing balances in order to calculate the average.

Cumulative Total for Day 10 will be  –

Example 2.3png
  • Cumulative Total for Day 10 = 124102856.26

Cumulative Total for Day 11 will be  –

Example 2.1png
  • Cumulative Total for Day 11 = 124739450.26

Similarly, we can calculate the cumulative total for the remaining days.

Example 2.2png

Therefore, the simple MA for 1st 10 days will be as follows,

Example 2.4png


The MA for 1st 10 days will be –

Example 2.5png
  • The MA for 1st 10 days = 12410285.63

Therefore, the simple MA for 11th day will be as follows,

Example 2.6png
  • MA for 11th Day = 12473945.03

Similarly, we can calculate the moving average for the remaining days

Example 2.7png

Example #3

Mr. Vivek wants to compute the estimated price of the onion for tomorrow based on an average of the last ten days. He believes that there is a margin of 10% upwards trends because of rising in the price of fuel. Also, he believes that the prices of onion are fluctuating based on moving averages. The last 10 days’ prices of the onion per kg are 15, 17, 22, 25, 21, 23, 25, 22, 20, 22. Based on the given criteria, you are required to compute the projected price of onion on day 11.


Use the following data for calculation of moving an average in excel

Day 115
Day 217
Day 322
Day 425
Day 521
Day 623
Day 725
Day 822
Day 920
Day 1022
Day 1121
Day 1220
Day 1317
Day 1419

Therefore, 7 days MA in excel will be as follows,

Moving Average Formula Example 3.1png
  • 7 Days MA = 21.14

Therefore, the next 7 days MA will be as follows,

Example 3.2png
  • = 22.14

Similarly, we can calculate 7 days MA as shown below

Moving Average Formula Example 3.3png

Estimated Price on Day 15

moving average formula Example 3.4png

The 7-day MA for the onion price is 20.14

It’s given that there will be a price increase for fuel, which could result in inflating of prices of onion.

Therefore, the projected price of onion on day 15 will be 20.14 * 1.10 = 22.16, which can be rounded off to 22

Uses of Moving Average

These kinds of averages are most commonly used in capital markets for analyzing the prices of the stock while conducting technical analysis. By using the moving average, the analyst tries to uncover if there any trends hidden in it. These are usually used as lagged indicators as these are based on previous numbers, and hence these averagesAveragesThe average value represents the set of data values; the average from the whole data is calculated by adding all the set values and dividing them by the number of values. Average = (a1 + a2 + …. + an)/nread more can never be greater than the closing prices. Further, it is also used in computing support and resistance level in technical charts.
