SMA
Simple Moving Average is one of the easiest trend tools to understand and one of the most common tools in chart analysis.
Start the lessonIntroduction
The simplest trend line
A Simple Moving Average (SMA) is calculated by adding the closing prices over a set number of periods and dividing by that number. It is called “simple” because each price is given equal weight.
The short answer
SMA helps smooth price data so you can see the broader direction of a stock without getting distracted by daily noise.
How it works
A simple formula
SMA = Sum of prices over N periods ÷ N
Example: a 5-day SMA takes the last 5 closing prices, adds them, and divides by 5. If the stock closes at ₹98, ₹101, ₹103, ₹102, and ₹106, the SMA is ₹102.00.
Simple example
Calculate a 5-day SMA
5-day SMA = ₹102.00
Latest price = ₹106.00. It is above the SMA.
Common mistakes
What beginners often misunderstand
Using the wrong time period
A 5-day SMA reacts faster than a 50-day SMA, so the time frame changes the signal.
Expecting exact predictions
The SMA helps with trend context, not guaranteed future moves.
Ignoring price context
The stock may be moving with strong momentum, even if the SMA is flat or gently rising.
Using it alone
SMA works best when combined with price action, volume, and risk management.
Key points
What to remember
- SMA stands for Simple Moving Average.
- It averages the last N periods to smooth price movement.
- A shorter SMA reacts faster than a longer SMA.
- A rising SMA often points to a stronger recent trend.
- Prices above the average can suggest recent strength.
- It is a trend tool, not a guarantee of future returns.
