Astro-Cycles and Speculative Markets

Astro Cycles and Speculative Markets by L. J. Jensen is a landmark text that bridges astrology, economics, and speculative trading. First published in the mid-20th century and later expanded, the work integrates decades of research into planetary cycles and their correlation with business trends, commodity prices, and financial markets.

Jensen begins by examining the “problem of economic causation” and argues that traditional explanations fail to account for the deeper rhythms driving markets. He introduces astro-cycles—planetary movements such as the Jupiter-Saturn conjunction, the Uranus cycle, and other cosmic rhythms—and demonstrates how they influence economic swings, mass psychology, and market sentiment.

The book then provides a practical “notebook reference manual” on applying astrological principles to forecasting. Topics include mundane rulerships, planetary progressions and transits, eclipses, angular relationships, and methods for synthesizing charts into usable forecasts. These tools are applied to real-world data, with examples spanning weather events, wars, commodity fluctuations, and stock market booms and busts.

Jensen’s approach is both esoteric and empirical. He insists that natural law and cosmic radiation—vibrations of the Sun and planets—interact with human affairs in ways too consistent to ignore. While controversial, his methods reflect nearly half a century of observation and analysis, first shared through pamphlets in the 1930s and later compiled into this comprehensive edition.

This book is not written for casual investors seeking quick profits. Rather, it is aimed at the serious trader or researcher who approaches markets like a navigator—dispassionate, disciplined, and guided by cyclical laws rather than fear and greed.

For students of Gann methods, financial astrology, or cycle theory, Astro Cycles and Speculative Markets offers an invaluable framework. It is both a historical artifact of astro-financial research and a practical guide for those daring enough to explore the cosmic dimensions of speculation.
