# What Is MACD? – Moving Average Convergence/Divergence

December 7, 2021 5 minutes

MACD is a calculation mainly used as part of technical analysis for stock investments. MACD or Moving Average Convergence Divergence is an oscillator that helps in identifying the strength of a trend and of a possible reversal. This calculation method uses moving averages to arrive at the oscillator values, converting three moving averages into two.

While selecting stock market investments, MACD acts as a technical indicator for plotting future price trends of stocks.

## How to calculate MACD?

The MACD indicator comprises three aspects:

1. The MACD line – estimates the distance between two moving averages
2. The signal line – identifies price momentum changes and triggers buy and sell signals
3. The histogram – difference between the MACD and the signal line

For calculating Moving Average Convergence Divergence, we must subtract the long term EMA from the short term EMA. Here are the MACD formulas:

Steps for MACD calculation and plotting

As discussed above, MACD calculation mainly considers two lines:

1. The MACD line
2. The signal line

First, the MACD line is established by:

• Reducing the 26-period moving average from the 12-period moving average.

Second, the signal line is the 9-period moving average of the MACD

Lastly, the MACD is displayed as a histogram.

• This is a graphical representation of the total distance between the two lines.
• In case the MACD cuts through the signal line from below, traders consider it as a buy signal
• If MACD cuts the signal line from above, traders use it as a sell signal
• These intersections are called MACD crossovers

## Benefits of using MACD

MACD indicator is widely used in the stock market analysis because

1. it is simple and
2. It is reliable

MACD enjoys popularity among those who perform a technical analysis of markets because of the two different signals in it:

1. the strength of a trend and
2. the turning point of a trend.

MACD is not just about determining an upward or downward trend. It also tells us about the strength of buy and sell signals.

If a trader uses a simple moving average to know to buy and sell signals, it can be delayed as the market conditions may change before the execution of the trade. This is where the moving average convergence/divergence indicator comes into the picture as it allows an up-to-date market movement representation.

## What are the flaws of MACD analysis?

Just as any indicator, the MACD comes with some flaws and should ideally be used in parallel to other technical analysis methods.

One drawback of MACD is that it acts as a short-term indicator. This is because the longest measurement that it can consider is the 26-day moving average. Therefore, if a trader has a longer-term outlook, the MACD may suit his/her requirements.

MACD is also trend-following since it provides signals only when a trend occurs, never before it is about to start. Therefore, if a trader wants to recognize an upcoming trend, the MACD cannot be of any use.

## Conclusion

The MACD indicator is very useful in technical analysis, as it brings together momentum and trend under one indicator. Developed by Gerald Appel, this method is known to be one of the easiest and effective momentum indicators. However, investors must remember that comparing MACD values for a group of securities that have varying prices is not possible. It should also not be used as an indicator for overbought and oversold levels.
