Ralph Nelson Elliott (1871-1948) was of that rarest of breeds, a true scholar in the practical world of finance. His fascinating theory of stock market behavior is remarkably unique in that it goes way beyond the usual "get rich quick" methods so characteristic of the bulk of the literature. As A. Hamilton Bolton, founder of the Bank Credit Analyst, said, "He developed his principle into a rational method of stock market analysis on a scale never before attempted. In fact, the Wave Principle is much bigger than a mere stock market method. Over the years, it has has a profound effect on a small coterie of investors who not only have the ability to recognize a theory of immense practical value, but who have the ability to recognize a theory of immense practical value, but who have the ability to appreciate the aesthetic beauty of the human experience in the abstract. The Wave Principle has fascinated philosophers, mathematicians, psychologists, theologians and financiers alike. Now, for the first time ever, after being out of print for decades, the original works of R. N. Elliott have been made available in this one complete volume.
