When it comes to investing, everyone wants a tool or method that can give them an edge. That’s where the Coppock Curve comes into play. It’s like a secret compass that tries to point investors to where the treasure might be buried, particularly when it comes to figuring out when to invest in the stock market.
In this article, we’ll explain the Coppock Curve indicator so you can consider adding it to your investment toolkit.
What Is the Coppock Curve?
The Coppock Curve is a momentum indicator originally designed by economist Edwin Coppock and introduced in an October 1962 issue of Barron’s magazine. Primarily utilised for identifying long-term trends in major stock indexes, this indicator can be adapted to various markets and timeframes, making it versatile for different trading strategies.
Functioning as an oscillator, the Coppock Curve moves above and below zero, signalling potential trend changes based on the momentum of a market index like the Nifty 50 or the Nifty 50 ETF. It calculates this by taking a weighted moving average of the rate of change (ROC) of the market index over specified periods.
The indicator is set with three main variables: a short ROC period and a long ROC period, typically 11 and 14 months, respectively, and a weighted moving average (WMA) usually set at 10.
Originally tailored for monthly charts to benefit long-term investors with infrequent signals, the Coppock Curve can also be applied to shorter timeframes such as weekly, daily, or even hourly, increasing the frequency of the signals and thus its applicability for various trading needs.
How To Calculate Coppock Curve?
To compute the Coppock Curve, follow these steps:
- Determine the 14-period rate of change (ROC14): This is calculated by comparing the most recent monthly closing price with the closing price from 14 months earlier.
- Calculate the 11-period rate of change (ROC11): Similar to the step above, compare the most recent closing price to the one from 11 months prior.
- Sum ROC14 and ROC11: Continue adding these values for each new period.
- Apply a 10-period weighted moving average (WMA10): Once you have at least 10 summed values of ROC14 and ROC11, compute the weighted moving average for these figures. Repeat this step for each subsequent period to update the Coppock Curve.
The Coppock Curve is thus expressed as WMA10 of the sum of ROC14 and ROC11, offering insights into potential shifts in market trends.
Why Use the Coppock Curve?
- Identifying Buying Opportunities: The main appeal of the Coppock Curve is its ability to highlight significant upward trends following a market downturn. When the curve rises from below to above zero, it suggests a strong buy signal, indicating that the market could be transitioning from a bearish (downward) to a bullish (upward) phase.
- Confirmation of Trends: Besides signalling the start of a bullish trend, the Coppock Curve can also confirm the strength of an ongoing uptrend when it continues to rise after crossing above zero.
- Long-term Strategy: The Coppock Curve is particularly valued for its long-term perspective. It helps investors filter out short-term fluctuations and focus on more significant trend reversals, making it ideal for strategic investors looking to hold stocks over extended periods.
- Risk Management: While primarily used for spotting buy signals, the Coppock Curve can also suggest when to be cautious. A downward turn in the curve could indicate that a bullish trend is weakening, prompting traders to consider taking profits or reevaluating their positions.
Using the Coppock Curve in Investing

Identifying Buy Signals
The most significant aspect of the Coppock Curve is its ability to signal potential long-term buying opportunities when it crosses above zero. This is interpreted as the market transitioning from a bear to a bull market. The idea is that the momentum is shifting upward, indicating growing investor confidence.

Timing Long-Term Investments
Because the Coppock Curve uses longer-term data points, it is best suited for identifying major market bottoms and potential long-term investment opportunities rather than short-term trading. It’s particularly popular among investors who manage retirement accounts or other long-term portfolios because it helps reduce the noise and emotional distress associated with short-term market fluctuations.
Practical Tips for Using the Coppock Curve in Trading
- Wait for Confirmation: Since the Coppock Curve is a lagging indicator (meaning it relies on past data), it’s wise to use it in conjunction with other analysis tools or indicators, like the RSI or MACD, to confirm signals before making trades.
- Monitor for Divergences: Occasionally, the Coppock Curve may diverge from the actual price movements—this can be a warning sign of an upcoming reversal. For example, if the curve starts declining but the price continues to rise, it might suggest the current uptrend is losing momentum.
- Adjust Settings as Needed: Although the traditional settings involve 14 and 11-month ROCs and a 10-month WMA, traders may adjust these based on their trading style and the specific characteristics of the stock or market they are analysing.
Advantages of the Coppock Curve
- Simplicity: Despite being based on complex emotional assumptions, the calculation and interpretation of the Coppock Curve are straightforward, making it accessible even to novice investors.
- Focus on Long-Term Trends: The indicator is designed to filter out the usual market noise and focus on substantial shifts, helping investors with long-term horizons.
- Historical Effectiveness: The Coppock Curve has successfully identified major bull markets historically, providing investors with valuable buy signals.
Limitations of the Coppock Curve
- Lagging Indicator: Like all momentum indicators, the Coppock Curve is a lagging indicator. This means it relies on past data and might not react quickly to sudden market changes.
- False Signals: While generally reliable, the Coppock Curve can sometimes provide false signals if the market conditions are unusually volatile or affected by extraordinary events.
- Limited Application for Short-Term Trading: Due to its long-term focus, the Coppock Curve is not suitable for short-term trading, where investors need to react quickly to price changes.
Bottom Line
The Coppock Curve isn’t a crystal ball, but it offers valuable insights into long-term market trends, helping traders and investors make more informed decisions. By understanding and applying this tool effectively, you can enhance your trading strategy, manage risks better, and potentially increase your chances of investment success.
Remember, no indicator is perfect. It’s crucial to use the Coppock Curve in conjunction with other tools and your analysis to make the best trading decisions. Happy trading!

What is the Coppock index indicator?
The Coppock index indicator is another name for the Coppock Curve. It’s used to identify major bottom points in stock indices, calculated by the weighted moving average of the sum of two rates of change.
How do you calculate the Coppock Curve?
Calculate the Coppock Curve by taking a 10-month weighted moving average of the sum of a 14-month and an 11-month rate of change of prices. This indicator helps identify major trend reversals in the market.
