A Trader's Guide to Financial Astrology: Forecasting Market Cycles Using Planetary and Lunar Movements

By Larry Pesavento and Shane Smoleny

Quick Summary

A systematic exploration of financial astrology as a market timing tool, using planetary transits, lunar cycles, and zodiac sign influences to forecast market turning points. The authors combine astronomical data with statistical testing and provide a framework for integrating astrological cycle analysis into trading strategies.

Executive Summary

Larry Pesavento and Shane Smoleny present a comprehensive guide to financial astrology, a niche but historically persistent branch of market analysis that uses planetary positions, lunar cycles, and astrological transits to forecast financial market turning points. The book covers the fundamentals of astrology as applied to markets -- planets, zodiac signs, planetary coordinate systems, transiting aspects, and visual representations of transits -- then moves to practical forecasting applications using solar and lunar cycles. The authors attempt to bring empirical rigor to the subject through efficiency tests, including a statistical analysis of Dow Jones behavior around new moons from 1885 to 2013.

Core Thesis

Financial markets exhibit cyclical behavior that correlates with astronomical phenomena, particularly planetary transits and lunar phases. While the authors acknowledge that astrology is not a standalone predictive system, they argue it can serve as a valuable supplementary timing tool for traders who combine it with technical analysis and proper risk management. The book's statistical testing aims to demonstrate that these correlations are not random.

Key Concepts and Frameworks

1. Planetary Influences -- Each planet is associated with specific energies and tendencies that influence market sentiment and behavior.
2. Zodiac Signs -- The position of planets within zodiac signs modulates their influence on markets.
3. Transiting Aspects -- Key angular relationships between planets (conjunctions, squares, oppositions, trines) mark potential turning points.
4. Solar Cycles -- Long-term market cycles correlated with solar activity and planetary orbital periods.
5. Lunar Cycles -- The new moon and full moon as recurring market timing signals, tested statistically on the Dow Jones over 128 years.
6. Walk-Forward Analysis -- The authors apply out-of-sample testing to validate their lunar cycle findings.
7. Bradley Barometer -- A composite astrological indicator used to forecast market direction.

Practical Applications for Traders

1. If using astrological timing, treat it as one input among many -- always require confirmation from price action, volume, or conventional technical indicators before acting.
2. Use lunar cycle data as a secondary filter for timing entries and exits around new and full moons.
3. Apply walk-forward testing to any astrological timing system rather than relying on in-sample backtests.
4. Combine astrological cycle windows with established technical analysis signals for higher-probability setups.
5. Maintain strict risk management regardless of astrological conviction -- always use predefined stops.

Critical Assessment

Strengths

• Attempts to bring statistical rigor to a field often dismissed as pseudoscience
• Comprehensive coverage of astrological concepts as applied to markets
• The lunar cycle efficiency test on 128 years of Dow data is methodologically interesting
• Practical in orientation, with clear frameworks for application

Limitations

• The fundamental premise that planetary positions influence financial markets lacks a causal mechanism supported by physics or neuroscience
• Statistical correlations found may be the result of data mining across many possible patterns
• The book does not adequately address publication bias or multiple comparison problems
• Most mainstream academic finance research has found no reliable predictive power in astrological variables

Conclusion

This book represents the most systematic modern attempt to present financial astrology as a disciplined trading tool. While the authors bring more empiricism than most treatments of the subject, the underlying causal claims remain unsubstantiated by mainstream science. Traders interested in cycle analysis may find some of the timing frameworks useful as one input among many, but should apply strict risk management and independent confirmation before acting on astrological signals.
