Financial astrology (also known as business astrology, economic astrology, and/or astro-economics) is a pseudoscientific practice of relating the movements of celestial bodies to events in financial markets. The use of astrology in financial markets is not consistent with standard economic or financial theory.
As with astrology in general, predictions are vague and hard dates are rarely given. Long term predictions are made based on patterns relative to astronomical events. Critics have pointed out that some astrological events that have been used in predictions occur so rarely that they may have never happened before within a human lifetime, thus having no precedent on which to predict results.
