Definition
A Simple Moving Average (SMA) calculates the average of a selected range of prices, typically the closing prices, by dividing the sum of those prices by the number of periods in that range. SMA serves as a lagging indicator as it considers past prices to identify trends in the asset over time. Picture it as trying to find your phone’s signal in a crowded restaurant - just keep listening to past conversations (prices) to guess the trend!
SMA vs EMA Comparison
| Feature | Simple Moving Average (SMA) | Exponential Moving Average (EMA) |
|---|---|---|
| Calculation Method | Average of prices over a selected range | Weighted average giving more emphasis to recent prices |
| Sensitivity to Price Change | Less sensitive, smoothes out fluctuations | More sensitive to recent price changes |
| Lag Time | More lag due to equal weight across all prices | Less lag due to increased weight of recent prices |
| Usefulness | Identifying general trends over time | Providing signals during quicker price movements |
Examples
Example Calculation:
For a simple moving average over 5 days:
| Day | Closing Price |
|---|---|
| 1 | $10 |
| 2 | $12 |
| 3 | $11 |
| 4 | $14 |
| 5 | $16 |
SMA Calculation:
- SMA = (10 + 12 + 11 + 14 + 16) / 5
- SMA = $63 / 5
- SMA = $12.60
Related Terms
- Exponential Moving Average (EMA): A type of moving average that places greater weight on more recent prices, making it more responsive to new information.
- Weighted Moving Average (WMA): A moving average that assigns different weights to prices, with more importance placed on specific data points.
