You can also use a weekly Coppock to fine tune the buy signal date. Essentially watch as the monthly Coppock forms a trough and then shift to the Weekly. The author used daily data of long duration to approximate a curve that would otherwise be used with Month end data. I have done this too in the past. It works okay. www.freestockcharts.com has the Coppock implemented as one of its suite of indicators.
Food for thought: The Coppock can be used on any cyclical stock. For example timing an entry into the home building market (opportunity now past).
When Jerry told me he had been using the Coppock since the late 1980's I was a sceptic. Then I back tested using it on the NASDAQ as a confirmation of IBD Follow-Through Days. Very valuable tool.
