Coppock Curve(redirected from Coppock indicator)
In technical analysis, a system for determining stock market rallies. The system uses a ten-month weighted moving average of the sum of eleven- and fourteen-month rates of change. Buy signals are determined when the curve turns upward after being below zero; analysts disagree as to whether the curve shows sell signals. The curve is thought to be a good way to determine rallies for stock markets, but not for more volatile commodity markets.
