Bradley Model

In 1948, Mr. Donald A. Bradley wrote a research booklet, "Stock Market Prediction -- The Planetary Barometer and How to Use It," on mass psychology and its impact on the U.S. stock market. The booklet is long since out of print and the publisher has indicated no future plan to republish his work.

At the heart of Bradley's work is the belief that elusive natural forces powerfully affect men's minds and emotions. These forces are the broad cycles which determine underlying trends in world economic and political affairs over years, decades, and beyond. Bradley concluded that the planetary aspects are the secret engine behind the cycles in mass psychology and he proved they are frequently revealed in the stock market. Bradley found that the sum of planetary relationships, involving 190 planetary position combinations, could be categorized into what he called the Long-Term and Middle-Term Indicators.

Those found currently using Bradley's theory are few and they closely guard what they know and reveal on the subject. At the end of an almost endless trail, we finally obtained a copy of Bradley's research. After studying his work, a decision was made to implement the intensive computations into a Microsoft Windows application. It's hard to believe Bradley completed his research without the benefit of a computer, doing the thousands of calculations by hand.
