What Is Moving Average | SMA?
A moving average is a technical analysis tool used in trading and investing to smooth out price movements over time.
It helps traders see the overall trend by filtering out short-term price noise.
How to calculate moving average
The most common type is the Simple Moving Average (SMA):
SMA = Sum of Closing Prices Over a Period / Number of Periods
Real-Life Moving Average Example
If a stock closes at:
-
Day 1 = 10
-
Day 2 = 12
-
Day 3 = 14
-
Day 4 = 16
-
Day 5 = 18
Then the 5-day moving average is:
SMA = (10 + 12 + 14 + 16 + 18) / 5 = 14
