Astrological Investing is simply as the name suggests - astrology related to anything to do with the money markets and how the movement of the planets affects individual financial instruments. It is also known as planetary finance or esoteric investing and uses a different system to normal or (mundane) astrology. The slow outer moving planets and eclipses are used mostly in money markets ,as opposed to the faster moving planets that are used in many horoscopes. Money based astrological predictions are based on the movement of individual planets at specific degrees - not based on gut feelings or intuition.
It is not actually the "stars aligning" you often hear which move financial markets, but (mostly) planets as they rotate around the solar system. When Planets combine with each other, they produce energy that resonate with events, people, countries, weather patterns and the financial markets. These energies can be positive or negative depending on the combination of planets involved. The art of astrological investing aims to know the difference between the positive and negative energies, and apply them to instruments that move in the markets. The job of a Stock Market Astrologer is to be able to apply time to these energies and implement them accordingly to the financial markets or specific financial instrument.
A good stock market astrologer or forecaster, will always combine traditional methods of trading such as technical analysis with astrology to see the big picture and try to forecast time and price. If you are not an experienced trader or long time astrologer using finance, it is unlikely you have the backtesting or experience to know how to apply these techniques successfully for both wins and losses.
No method in the stock market can deliver 100% accuracy, however stock market astrology is based on historical data, backtesting and statistics based on a "very" high rate of occurrence and probability and needs to evolve as markets evolve.
