Weighted Moving Average: Meaning & How to Calculate

    Summary

    The Weighted Moving Average (WMA) is a vital technical indicator that prioritizes recent price data to provide a more responsive view of market trends. This guide explains how to calculate WMA by assigning linear weights, compares it with SMA and EMA, and demonstrates its role in identifying buy/sell signals. Master this tool to filter market noise and enhance your short-term trading precision.

    A weighted moving average is a technical indicator that assigns higher weight to recent prices than older prices. It is commonly used to smooth price data so short-term fluctuations appear less noisy. WMA is used in chart analysis to observe how recent price movement compares with the recent average.

    A weighted moving average is computed by multiplying each price with its specified weight, summing up the products, and dividing the sum by the total weights. The latest data is given higher weights; thus, the trend of current prices is more accurately reflected.

    WMA is often discussed for trend and momentum interpretation in technical analysis; it should not be treated as a standalone trading signal. It enhances technical traders' decision-making by simplifying price analysis in volatile markets.

    What is the Weighted Moving Average (WMA)?

    The weighted moving average is a famous type of moving average that is used to smooth out price data and identify trends. Typically, stock prices move a lot from day to day. Hence, there tends to be a lot of noise in their movements, which makes it difficult to interpret them. So, traders use WMA, which is calculated by giving more weight to recent prices than to older prices. To calculate a security's WMA, we assign a weight to each of its price points in a period. Based on this analysis, we can gauge the direction a stock's price is likely to take. WMA reacts faster to price fluctuations than SMA, which makes it a better market in highly fluctuating markets.  

    How to Calculate Weighted Moving Average?

    While calculating the weighted moving average (WMA), we assign more weight to recent price points than to older price points. However, we need to ensure that the sum of all weights assigned must equal 100% or 1. The higher the weight, the higher the importance of that price point.

    We need to follow these steps to calculate the weighted moving average:

    a) Identify the data set: The first step is to identify the data set to calculate WMA. Let us say that we want to find out the weighted moving average of a stock’s price between August 1 and August 5. Assume that the stock traded at these prices ₹100, ₹110, ₹105, ₹103, and ₹107 on August 1, August 2, August 3, August 4, and August 5, respectively.

    b) Assign weights to prices: In the second step, we have to assign weights to prices. Remember that weights are assigned linearly to calculate the weighted moving average. Let us say that we assign these weights 1, 2, 3, 4, & 5 to prices on August 1, August 2, August 3, August 4, and August 5, respectively. If we add 1, 2, 3, 4, and 5, we will arrive at 15. The following table shows how weights will be assigned to prices.

    Date

    Closing Price

    Weightage

    August 1

    100

    1/15 = 0.067

    August 2

    110

    2/15 = 0.133

    August 3

    105

    3/15 = 0.2

    August 4

    103

    4/15 = 0.267

    August 5

    107

    5/15 = 0.333

    c)  Multiply each price by its weight: Now, we need to multiply each price observation with its weightage, which is done in the table below:

    Date

    Closing Price

    Weightage

    Price * Weightage

    August 1

    100

    0.067

    6.7

    August 2

    110

    0.133

    14.63

    August 3

    105

    0.2

    21

    August 4

    103

    0.267

    27.501

    August 5

    107

    0.333

    35.631

    d) Sum up all the prices multiplied by their respective weight: Now, we need to add all the prices that are multiplied by their respective weight to calculate the WMA as shown below

    Weighted Moving Average = 6.7 + 14.63 + 21 + 27.501 + 35.631 = 105.462

    WMA vs. Simple and Exponential Moving Averages

    It is extremely important to know the differences between the weighted moving average (WMA), the simple moving average, and the exponential moving average (EMA) for all kinds of traders. So, please refer to the table below:

    Criteria

    Weighted Moving Average (WMA)

    Simple Moving Average (SMA)

    Exponential Moving Average (EMA)

    How is it calculated?

    We multiply each price point with a weight. Recent observations are assigned a higher weight than older observations.

    We calculate a simple average of all the price observations over a period.

    We assign exponential weights to prices. We assign higher weights to recent prices than to older prices.

    How does it respond to price fluctuations?

    WMA is more responsive to recent price changes than SMA because it assigns more weight to recent price points.

    Because all prices are assigned an equal weight, SMA is less responsive to recent price changes.

    As exponential weighting is used, EMA is the most responsive moving average to recent price changes.

    When is it used?

    It is more suitable for short term trend identification than SMA.

    It is suited for long term trend identification.

    This is the moving average to identify trends in the short term because it is the most responsive to recent price changes.

    How difficult is it to calculate?

    WMA is more difficult to calculate than SMA because it requires assigning weights to price points.

    SMA is the simplest moving average to calculate. All we need to do is add the price points and divide that by the number of observations.

    Because exponential weights are used in this case, EMA is the most difficult moving average to calculate.
