The Key to Speculation on the New York Stock Exchange

The Key to Speculation on the New York Stock Exchange by Jack Gillen is a bold and unconventional exploration of how astrology can be applied to financial markets. Published in 1979, the book presents Gillen’s lifelong research into planetary cycles, market psychology, and timing methods that challenge traditional economic thinking.

Jack Gillen, often described as a “modern Nostradamus,” began his studies in the early 1960s, extending his research from gambling systems and sports predictions into the financial world. His early manuscript, The Key to Speculation, circulated privately in 1970, gained attention after his stock selections surged in value. Yet Gillen resisted broader publication, believing many were unprepared to accept astrology as a legitimate forecasting tool. Eventually, after demonstrating stunning accuracy—including predicting massive volume surges in 1978 on the NYSE—he agreed to release his complete system for public study.

The book explains how planetary aspects, solar and lunar cycles, and sensitive degrees influence market swings. Gillen details correlations between planetary transits and panics, crashes, recessions, and rallies, while also analyzing corporate charts and the natal chart of the NYSE itself. He even includes planetary tables and sensitive degree listings for practical application.

Gillen’s forecasts, often verified in real time, established his reputation in both financial and astrological circles. His methods were regularly covered in U.S. newspapers and talk shows, earning him credibility despite skepticism.

For students of financial astrology, W.D. Gann-inspired cycle theory, or anyone interested in unconventional forecasting, The Key to Speculation remains a fascinating and practical guide. It blends rigorous observation, astrological tradition, and bold predictions into a framework for understanding—and anticipating—the rhythms of Wall Street.
