Jim Tillman, Publisher, Cycletrend


We have published a technical market letter for over 28 years, during which time we have studied and used many of the classical methodologies, but our greatest success has come from the study of stock market cycles. It was with great interest that I met Bill Erman over ten years ago, when he shared a small part of his unique approach to analyzing market movements. Since that time his work has progressed into what might be called an entirely new field of cyclical analysis. Ermanometry is most definitely original and cutting edge. Viewing the market as spherical, his is the first method that we know of that can project turning points, for moves that span many years, to the precise day. His work is mind expanding and a very worthwhile method to explore and learn.
