Definition§
The Rate of Change (ROC) is a financial momentum indicator that measures the speed at which a variable changes over a specified period. It can be expressed as $ROC = \frac{(Current Price - Price , n , periods , ago)}{Price , n , periods , ago} \times 100$, providing insight into the acceleration or deceleration of price changes rather than the magnitude of those changes.
ROC vs Momentum Indicator§
| Feature | Rate of Change (ROC) | Momentum Indicator |
|---|---|---|
| Definition | Measures the change in price relative to time | Measures the strength of price movements |
| Formula | $ROC = \frac{(Current Price - Price , n , periods , ago)}{Price , n , periods , ago} \times 100$ | $Momentum = Current Price - Price , n , periods , ago$ |
| Application | Identify potential price reversals | Measure the strength of a trend |
| Output | A percentage indicating how much prices have changed | A numerical value identifying a trend’s direction |
Example§
Suppose the current stock price is $120 and the price 5 days ago was $100. The ROC would be calculated as:
$$ ROC = \frac{(120 - 100)}{100} \times 100 = 20% $$
This indicates a 20% increase in price over the last five days.

Frequently Asked Questions§
Q: How is Rate of Change used in trading? A: Traders use ROC to identify trends and potential reversals. If ROC is high, it suggests strong momentum; if it suddenly drops, it could mean a change in direction.
Q: Can ROC indicate overbought or oversold conditions? A: Yes! If the ROC is extremely high, the asset may be overbought. Conversely, an extremely low ROC can indicate oversold conditions.
Q: Is a higher ROC always better? A: Not necessarily! A higher ROC indicates more momentum, but it can also suggest overextension, which can lead to a pullback.
