Introduction
The Coppock Curve Indicator is a widely used momentum-based technical analysis tool designed to detect the start of a new bear market or bull market by studying long-term stock market trends. Edwin Coppock, a market analyst and economist, created the indicator in the late 1960s to help long-term investors spot the beginning of new bull markets, naming it after himself.
The Coppock Curve Indicator relies on two main components: a weighted moving average (WMA) and the rate of change (ROC). The ROC over a set period, typically 11 or 14 months, is summed and a WMA is applied to the result. The resulting line is plotted on a chart, with buy and sell signals triggered by the indicator’s movements.
A buy signal is generated when the Coppock Curve Indicator crosses above the zero line, indicating a new bull market. Conversely, when the indicator crosses below the zero line, a sell signal is generated, indicating a new bear market. These signals are valuable to traders and investors, who can use them to make informed decisions about when to enter or exit the market.
Computing the Coppock Curve Indicator
The Coppock Curve Indicator can be calculated using the formula:
Coppock Curve Indicator = WMA(ROC(n) + ROC(m))
Where:
- ROC(n) is the rate of change over n months
- ROC(m) is the rate of change over m months
- WMA is a weighted moving average
For the Coppock Curve Indicator, a long-term rate of change period of 11 or 14 months is typically used, along with a short-term rate of change period of 1 month. The weighted moving average is commonly set at 10 periods.
To calculate the Coppock Curve Indicator, follow these steps:
1. Calculate the rate of change (ROC) for the long-term period (n) by subtracting the closing price n months ago from the current closing price, dividing the result by the closing price n months ago, and multiplying the result by 100 to get a percentage.
2. Calculate the rate of change (ROC) for the short-term period (m) using the same formula as above.
3. Add the two ROC values together.
4. Apply a 10-period WMA to the sum of the ROC values.
5. Plot the resulting line on a chart and use it to identify buy and sell signals as explained earlier.
Understanding the Coppock Curve Indicator in technical analysis
The Coppock Indicator is a significant technical analysis tool that can help identify the start of new bull markets. It’s based on the idea that long-term market trends are influenced by fundamental economic factors, which are reflected in market prices over time.
A buy signal from the Coppock Indicator suggests that the market has hit a bottom and is beginning a new bull market. This can be helpful for long-term investors looking to enter the market at the start of an upward trend. Conversely, a sell signal indicates that the market has reached its peak and is entering a new bear market. This can be beneficial for investors who want to exit the market or take measures to safeguard their portfolio during a downturn.
It’s worth noting that the Coppock Indicator isn’t a flawless tool and can produce false signals in specific market conditions. Traders should use it in conjunction with other technical indicators and fundamental analysis to make well-informed investment decisions. Nevertheless, when used properly, the Coppock Indicator can be a valuable asset to a trader’s toolbox.
Edwin Coppock’s suggestions on how to use the Coppock Curve Indicator
The Coppock Indicator, developed by Edwin Coppock, is a long-term trend-following tool that is most effective in identifying the start of new bull markets. However, Coppock advised caution and recommended using the indicator in combination with other technical and fundamental analysis tools for making informed investment decisions.
Coppock recognized that the market is complex and unpredictable and that the indicator should not be relied upon as the sole basis for investment decisions. He suggested using the indicator to identify the long-term trend of the market and to use it along with other tools to make informed decisions based on market conditions, individual investment goals, and risk tolerance.
