Coppock Curve: A Long-Term Momentum Indicator
Coppock Curve: A Practical Guide for Investors
The Coppock Curve is a long-term momentum indicator developed by Edwin Coppock in 1962. It was designed to spot major buying opportunities in stock indices. Indian investors use the Coppock Curve to identify possible long-term lows and shifts in market trend.
This guide explains how the Coppock Curve works and how to use it.
What Is the Coppock Curve?
The Coppock Curve is a momentum indicator built on monthly data. It combines two rate-of-change values with a smoothed moving average.
The output is a single curve that fluctuates above and below zero.
How the Coppock Curve Works
The standard formula uses:
- 14-month rate of change of the index
- 11-month rate of change of the index
- 10-month weighted moving average of the sum
The result is plotted as one curve. Most platforms calculate this automatically.
Why the Coppock Curve Matters
The tool matters for three reasons:
- It signals major long-term buying points
- It captures shifts in momentum
- It supports better long-term entry timing
A clean Coppock signal is rare but useful.
How to Read the Curve
Use these guides:
- Curve crosses above zero from below: long-term buy signal
- Curve stays above zero: bullish bias
- Curve falls below zero: bearish bias
The original use was a buy signal in indices, but traders also watch the curve direction.
How to Use the Coppock Curve
A common method:
- Apply the Coppock Curve on a monthly chart
- Wait for the curve to cross above zero
- Confirm with broader market trends
- Enter long positions in steps
- Plan exits at major resistance levels
This routine adds discipline to long-term entries.

Monthly charts give the cleanest signals.
Example of Coppock Curve Use
Suppose the Nifty Coppock Curve has been falling for months. The curve then turns up and crosses above zero. The signal hints at a long-term buying opportunity. Investors build positions in stages.

New investors often:
- Use the Coppock Curve on short time frames
- Trade every minor cross

A clean checklist avoids these errors.

Coppock Curve vs MACD
The two differ:

Coppock Curve is for long-term investors.
Coppock Curve and Risk Management
Risk control includes:
- Position sizing based on risk tolerance

Sound risk control protects capital.
Coppock Curve and Indian Bull Markets
