The Coppock Curve, conceived by Edwin Coppock in 1962, stands as a pivotal long-term price momentum indicator within the finance industry. This unassuming tool plays a crucial role in recognizing significant shifts in stock market indices, providing practical buy and sell signals based on momentum changes. Applied predominantly to monthly candlestick charts, its signals serve as valuable guides for investors in making informed decisions, devoid of unnecessary embellishments.
Calculating the coppock curve
The meticulous calculation of the Coppock Curve involves a 10-month weighted moving average, incorporating the 14-month and 11-month rates of change. This methodical approach ensures a reliable indicator for making well-informed investment decisions. The steps include calculating the rate of change for specific periods and subsequently taking a weighted moving average, ensuring precision and accuracy in financial analysis.
Interpreting the coppock curve
When the Coppock Curve rises above zero, it signals a buying opportunity, while a drop below zero indicates a sell signal. This indicator, tailored for long-term time series analysis, is often employed with monthly candlestick charts. Despite its inherent lag, the Coppock Curve’s uncorrelated appearance to price makes it a valuable tool for predicting market trends without unnecessary speculative language.
Example of how to use the coppock curve
Practical application of the Coppock Curve involves analyzing a monthly price chart of a stock index or ETF. Buying is recommended when the Curve rises above zero, and selling is considered when it falls below zero. For existing investments, holding onto them is advised when the Coppock Curve is above zero. A practical example is illustrated using the SPDR S&P 500 ETF (SPY), showcasing buy and sell signals since mid-1995.
The coppock curve vs. Rate of relative strength index (RSI)
While the Coppock Curve focuses on long-term momentum using the rate of change, the relative strength index (RSI) assesses current price levels compared to past prices. The distinct calculations result in different trade signals and information, offering investors a diversified toolkit for financial analysis devoid of unnecessary embellishments.
